To a certain extent, priority is claimed in respect of each of the above disclosed applications.

The field of technology to which the invention belongs

The present invention relates to an artificial public urban beach entertainment complex, containing as the main object of the complex a tropical-style artificial crystal clear lagoon, adjacent to at least one entertainment, educational, cultural, sports or commercial facility, while the complex has controlled public access and with clear waters and sandy beaches, it provides the impression and feeling of being on a tropical beach, while the lagoon contains a surf attraction.

The present invention further relates to a method for effectively utilizing facilities and land that is vacant, low utilization, of limited use, and/or adjacent to or adjacent to recreational, educational, cultural, sports, or commercial establishments by providing a publicly accessible urban beach entertainment complex. with the main facility in the form of an artificial tropical-style crystal clear lagoon containing a surfing attraction.

Background of the invention

There are innumerable land areas in the world, such as unoccupied land, that have a low utilization rate due to various factors. There are also various recreational, educational, sports and commercial establishments bordering large areas of land that can benefit from development. Such limited or unused sites usually require the payment of monthly or annual maintenance fees or taxes, and their use generates little or no direct profit. For example, it has been estimated that in the United States up to 25% of the total land area in cities consists of unoccupied land (according to experts), and it is recommended that such spaces be used more efficiently in order to meet the current and future demands of urban residents. This urban unoccupied land includes land that could be used for future real estate development, among other uses. In addition, there are sites that are not used, such as undeveloped sites, abandoned sites, or agricultural or uncultivated land, which can be found in relative proximity to urban centers.

Event arenas, museums, amusement parks, water parks, stadiums, golf courses, indoor clubs, zoos, aquariums, shopping malls, university campuses, casinos , cruise ship ports, racing tracks, racetracks and Olympic venues, among others.

Based on research by the present inventor, it has been estimated that there are more than 100,000 of these types of establishments in the world, most of which have nearby or bordering land that is currently underutilized or of limited use, which is a major global marketplace for new and innovative ideas that make good use of the aforementioned sites and that significantly improve and change the way of life of people living in the immediate vicinity of these sites. Additionally, many of these establishments have extensive associated infrastructure such as parking lots, driveways, and large spaces that are unused or have low utilization rates. For example, some stadiums are used only once or twice a week, and the rest of the time their existing infrastructure has no alternative or additional use. The same happens in the interior of racecourses and racing tracks, which are often not used or used only during racing (i.e. not used for alternative or additional purposes). In addition, some racing tracks have closed and therefore the buildings are not used in an efficient way.

It is also important to note that there are several significant global retail-related trends emerging at the moment. In particular, malls and stores are closing on an unprecedented scale. This makes large empty spaces available that can be rearranged and used for other purposes. It is estimated that a quarter of all malls in the US will close within the next five years (according to forecasts by banking group Credit Suisse). In many cases, these spaces no longer offer what the population wants, such as recreational and cultural activities, a meeting place to spend time with family and friends, additional playgrounds and environments for recreation and improvement of physical and mental health.

Another significant new trend is that golf courses have gone from explosive growth to massive closures. More than 800 golf courses according to Bloomberg

- 1,041,087 have been closed in the US in the last decade. An often cited reason is that golf is not a family sport, which results in less interest from people who want to share new activities and experiences with their families and friends. Golf course closures leave owners with large tracts of land that can be abandoned. This creates a big problem where unoccupied lots can eventually turn into abandoned lots. As mentioned earlier, the closures reflect the changing preferences of people for entertainment and leisure, seeking outdoor recreational and cultural activities, appreciating time spent with family and friends, and looking for a new ideal meeting place.

Therefore, the growing availability of unoccupied land, land with limited use, land with low utilization rate, or land bordering or located near recreational, educational, sports or commercial establishments is an untapped market that has not seen innovation in the last few years and that you can implement a newly created complex that people who live near this complex like, which provides more efficient use cases.

In addition to changing the availability of low-use spaces, city life and needs have also changed over the years. The number of publicly accessible outdoor recreational spaces has decreased due to urbanization and population growth. It is often said that life in big cities is getting more and more stressful. The UN notes that with over 50% of the world's population living in urban areas, there is a growing and very important need to provide attractive and versatile recreational spaces, especially outdoors, that can help people get out of their busy routine and relax in a peaceful paradise atmosphere. According to these trends, the period of gatherings in closed spaces such as shopping malls, cinemas and indoor gyms is coming to an end and there is a need for open spaces of paradise to improve the lifestyle of people around the world.

Paradise and tropical beaches have been found to be one of the preferred travel destinations of people all over the world. The desire to relax and enjoy the outdoors is universal, especially during the summer and warmer months. Tropical surroundings and beaches are one of the most preferred destinations by travelers around the world. In addition, the beaches are very popular with travelers to their own countries, who seek to escape from the usual daily life and relax and recover in a tropical paradise. People in general tend to visit and become regular visitors to recreational areas, especially near sea and beach areas. For example, in the US, the coastline makes up less than 10% of the total land area (excluding Alaska), but accommodates 39% of the total population, according to the National Ocean Service. However, many of the coastline beaches are unsuitable for swimming, with very high winds, dark sand and little safety in regards to currents, surf, marine life, rocks and other associated risks. This creates a situation in which many people do not swim or do water sports on or near such beaches.

Instead, people dream of white sandy beaches with tropical turquoise waters. Their dreams include immersing themselves in a beach setting with the look and feel of a tropical environment, enjoying an idyllic lifestyle next to crystal clear waters with natural wave movement. Also in these types of environments, doing water sports other than swimming is a popular activity that people demand. Such water sports may not be practiced in backyard pools or public pools.

Traditional swimming pools simply do not allow such idyllic beach areas to be introduced. For the purposes of the present invention, and based on its worldwide definition, the term traditional swimming pool means a sealed body of water constructed from concrete or similar materials, the operation of which requires the total volume of water contained in the pool to be filtered 4 times a day, and also requires the maintenance of a constant residual chlorine level. of at least 1.0 ppm in total water according to Florida regulations such as Florida Department of Health Rule 64E-9.

Although the public pool provides a swimmable body of water, it does not provide the essential parameters needed to create the look and feel of a beach lifestyle, urban beach entertainment complex, and the feeling of being in a tropical setting. Several reasons include: (i) very high construction and operating costs, including electricity requirements and chemical requirements, which limits their size, hence only small pools are built; (ii) the general use of right angles, straight lines and unnatural forms; (iii) pools usually do not have sandy beach areas; (iv) the color of the water appears artificial and unnatural due to their small size and shallow depth; (v) pools do not have natural wave movement because their size does not allow the wave generation area to create larger and more natural waves; (vi) they do not allow water sports due to their shallow depth and small size; (vii) they have a strong smell of chlorine or chemicals; (viii) and usually they are not surrounded by tropical or beach scenery with jetties. More:

- 2 041087 (i) Traditional swimming pools are very expensive to build and maintain and are usually made of thick concrete structures with an artificial appearance.

For example, the Fleishhacker Pool, located in California, has a surface area of

15,000 m ² had to be closed in 1971 due to water quality problems and high costs. There are several additional examples of such situations around the world.

Based on the present cost of building a swimming pool, an approximately 1,000 ^m2 Olympic-sized pool costs approximately US$1.8 million in direct construction costs and uses over 23,000 kWh of electricity per month and over 25 gallons of chlorine daily, equivalent to direct monthly costs. for operation in the amount of more than $6,000. Increasing the size and volume of such traditional pools results in extremely high construction costs, due in part to the use of thick concrete bottoms with waterproof paint and large and expensive equipment to maintain water quality. Therefore, because it is economically and technically difficult to increase the size of conventional swimming pools, they do not reach a size large enough to resemble tropical seas and/or allow for water sports.

The operating costs of large pools are high and economically unsustainable due to the high energy consumption to filter the full volume of water 4 times a day and due to the use of chlorine to keep the chlorine levels high and constant. Consequently, swimming pools have a very large carbon footprint, which affects the environmental friendliness of such structures.

(ii) Public swimming pools are usually built using straight lines, right angles, and rectangular geometries, which are different from the natural and curved forms of pools that resemble tropical seas or coasts.

(iii) Pools usually do not have sandy beach areas, which creates a more artificial appearance. Traditional pools are usually constructed of thick concrete and covered with paint or tiles, giving the appearance of an artificial structure used to hold water rather than the appearance of an idyllic beach with white sand beaches reminiscent of the appearance of the tropics.

(iv) The color and hue of the water that is achieved in swimming pools usually appears artificial due to the depth of the pools. Since the depth of the pools is usually less than 1.5 m, the reflection of the Sun from the bottom of the pools does not create a rich and deep turquoise color, such as the pure turquoise color found in tropical seas. Also, since the pools are small in size, they evoke the feeling of being immersed in an artificial rather than a beach atmosphere.

(v) Due to the small size of the pools, the wave activity generated in the pools appears to be artificial with little movement of the water surface. The small size and, in particular, the short length of the pools (the greatest distance from one point on the perimeter of the pool to another point located on the perimeter of the pool) creates a situation in which the wind does not have a noticeable effect on the surface of a small pool. The influence of wind over a long distance above the water is called the wave generation region, which affects the wave motion of the water surface. Small pools with small surfaces do not allow the creation of a wave generation area and therefore do not create larger and more natural waves and wave activity.

(vi) Also, traditional swimming pools are not usually provided with conditions for water sports, since many water sports require large surface areas and large depths that cannot be obtained using traditional technologies for building and operating swimming pools, since it is technically and economically impractical to build and serve larger scales. Water sports not commonly practiced in small pools include sailing, rowing, windsurfing, water skiing, power skiing, flowriding, stand up paddle boarding, jet skiing and kite surfing, among others. For example, stand-up paddleboarding, which is one of the fastest growing water sports in the United States, cannot be practiced in small pools because it does not achieve the desired sensation of paddling in a large space.

(vii) Many swimming pools have a strong odor of chlorine or chemicals because their operating technology and worldwide regulations require that the residual chlorine level in the water be maintained at a constant and high level to ensure proper disinfection. Consequently, the smell of chemicals interferes with the illusion of being in a tropical paradise and instead conveys the feeling of being in an artificial setting. Pools generally need to maintain a minimum residual chlorine level of 1ppm, which creates a very noticeable chlorine smell.

(viii) The pools are not usually surrounded by tropical or beach scenery such as palm trees and usually do not have piers or pontoons as no water sports are practiced in such small pools. Consequently, the look and feel associated with an idyllic beach life and tropical paradise that includes several water sports is not created.

Based on the above, as life in the cities has become more stressful and travel to

- 3 041087

Antilles or other tropical beach is inaccessible to most people (for example, due to lack of time, money, long distance or other restrictions), the present invention overcomes the aforementioned urban problem of lack of recreational space in a new and innovative way by creating a beautiful tropical environment with crystal clear water and white sandy beaches on urban land or urban areas with low utilization rate through an artificial urban beach entertainment complex with a crystal clear lagoon as the main facility. These recreational areas are designed to change the way people around the world live by providing an idyllic beach setting that promotes relaxation and pure water enjoyment, which can reduce conscious or subconscious stress and improve mental and physical health. A variety of activities, including recreational, social, cultural and sports activities, can be carried out around the main lagoon facility, with the aim of transforming the area into a beautiful and desirable landscape.

In addition, in recent years there has been a development of technologies for creating artificial waves for surfing, and such technologies are provided mainly as independent attractions designed for visitors involved in surfing or similar sports. However, such surf generators have not been used as part of an entertainment complex, like the generator used in the present invention, according to which additional facilities and platforms are provided in order to create a meeting place of the 21st century.

According to another aspect of the present invention, a method is provided for the efficient use of land with limited use, by creating a public urban beach entertainment complex, the method includes selecting a site with a minimum total surface equal to 16000 m ² , while the site is selected from unoccupied land, places with low the rate of use, land of limited use, or land bordering or adjacent to recreational, educational, sports or commercial establishments with a minimum adjacent population of 500,000 within a 50 mile radius with road links; and having a water supply with sufficient availability for use on the site; creating a main lagoon facility having a surf part and a non-surf part, the non-surf part of the lagoon having a bottom, perimeter and surface area of 10,000 to 200,000 m ² to recreate the look and feel of a tropical lifestyle, while most of the bottom is made of flexible plastic material; and wherein at least one part of the lagoon further comprises an edge with a gradual increase in depth, reminiscent of the natural edge of the beach; and wherein the surf portion includes an artificial surf wave generator configured to generate surf waves in the surf portion of the lagoon; creating at least one sandy beach area and recreational area surrounding the perimeter of the lagoon, wherein the sand in the sandy beach area is light in color, thereby resembling a tropical beach, and wherein the sandy beach area and recreational area have a surface area of at least 2500 m ² ; connecting a water source to the lagoon via a water supply system, the water supply system providing fill and/or make-up water for the lagoon; providing a water purification system for purifying water in the lagoon, the water purification system being located and designed to use at least 50% less electricity compared to a traditional centralized swimming pool filtration system, while the filtering capacity and volume of filtered water are at least 50% lower than a traditional swimming pool filtration system that filters the full volume of water 4 times a day; restricting at least a portion of a lagoon, a sandy beach area, and a recreational area with a physical fence, wherein the area within the physical fence further forms an urban beach entertainment complex, the fence being positioned and configured to restrict individual access to the complex; placement of the access control system in at least one part of the physical fence, while the access control system is located and designed in such a way as to selectively provide the passage of individuals to at least part of the urban beach entertainment complex; and creating at least one ancillary facility located in an entertainment area and selected from a group of commercial, recreational, educational, cultural, residential and sports facilities; while separate entrance fees provide revenue to the urban beach entertainment complex, thereby ensuring the efficient use of a facility or land that has limited use.

Accordingly, embodiments created according to the principles of the present invention provide people around the world living near urban centers with the opportunity to escape from everyday life and enjoy the beautiful environment of a tropical beach with a crystal clear lagoon with white sandy beaches as its main object. These public urban beach resorts have the potential to become the main meeting place of the 21st century, thereby changing the way people around the world live.

The public beach entertainment complex of the city contains a surfing attraction that allows you to practice sports such as surfing, boogie surfing, body surfing, etc. In addition, the surf attraction can provide the look and sound of an ocean beach, adding to the aesthetic of a tropical beach.

These and various other features, as well as the advantages that characterize the present invention, will become apparent from reading the following detailed description and review of the related drawings.

Detailed description of the invention

The present invention relates to an artificial public urban beach entertainment complex with a tropical style artificial lagoon as the main facility of the complex with surrounding entertainment, educational, sports and/or commercial facilities, while the complex has controlled public access and provides the look and feel of a tropical beach with clear water and sandy beaches.

The present invention further relates to a method for efficiently utilizing facilities and land that have a low utilization rate or border or are located near recreational, educational, sports or commercial establishments by providing a publicly accessible urban beach entertainment complex with a tropical-style artificial crystal clear lagoon as the main object. The method enables revenue generation and efficiency gains by combining vacant lots, low utilization lots, restricted areas, or lots that border entertainment, educational, sports and/or commercial establishments with the development of urban beach recreational complexes with artificial crystal tropical-style clean lagoon as the main facility, while the complex has controlled public access and, thus, provides paid public admission to at least one section of the complex. By transforming such sites into a tropical paradise through the creation of urban beach entertainment complexes with the main facility in the form of a tropical-style artificial crystal clear lagoon with white sandy beaches, the effective use of sites with income generation through the collection of entrance fees to the complex and other types of income generated from activities carried out in the complex. It will be apparent to those skilled in the art that the ultimate goal of a publicly accessible urban beach complex is a profitable operation.

In the context of this document, the phrase "tropical lagoon" means a large body of water with crystal clear water, the hue and color of the water varying from turquoise to emerald, which are natural for a tropical setting (i.e. in the tropics), where the depth varies from 0.5 up to 6 m and above. These tropical-style lagoons have a light bottom, usually due to the lighter color of the sand, with depth differences creating different hues in the same bodies of water, with clearer water in the shallows and richer water at depth. These tropical-style lagoons form a typical Caribbean landscape, recognized throughout the world and known to the general public.

Also in the context of this document, the term urban refers to a type of setting and terrain that has road connections and access and is surrounded by a population of at least 200,000 people within a 30 mile radius.

One advantage of the present invention is to economically create a piece of tropical paradise in cities by providing a public urban beach entertainment complex with a main facility in the form of a large crystal clear tropical-style artificial lagoon, allowing recreational, cultural, sports, educational and commercial activities around the lagoon containing surfing attraction; and thus in providing a welcome meeting place for the 21st century.

- 6 041087

An additional advantage of the present invention is to provide a method for the efficient use of areas such as unoccupied land, areas that currently have a low utilization rate, or that border or are located near educational, sports, recreational or commercial establishments. The method according to the present invention transforms such sites into a tropical paradise by creating urban beach entertainment complexes with a tropical-style artificial crystal clear lagoon as the main facility and white sandy beaches, while the sites are effectively used and receive potential income from complex entry fees ( as well as income from other services provided in the complex).

These cost-effective public urban beach entertainment complexes represent a brand new idea to allow people to experience vacation-like spaces anywhere in the world, even blocks away from home, providing a solution to the growing demand for new recreational spaces and secluded beach-like spaces on the lot. which have not previously been used for this purpose. Complexes built according to the principles of the present invention transform sites into family vacation spots and upgrade any establishment into a next-generation entertainment venue. For example, if you asked 50 years ago where people go to stretch, they answered that they go to the park or jogging through the streets, and if you ask today, people answer that they go to the gym. In the same way, when people want to go to the beach, they usually need to travel long distances by car or plane and spend considerable time moving around. However, the present invention creates a beach close to their homes, so it will represent a significant change in people's lifestyle.

These public urban beach resorts and their main facilities in the form of large crystal clear lagoons with a tropical look and feel provide an incomparable landscape that is aesthetically pleasing, with plenty of turquoise water that creates a sense of relaxation and idyll. Consequently, this environment creates an extremely attractive and beautiful location where the environment can be used for activities that are currently being carried out in much less attractive places and in much worse general conditions. Therefore, these urban recreational complexes and their main facilities in the form of large crystal clear lagoons with tropical appearance and atmosphere should be the meeting point of the 21st century.

It is important to note that the surfing attraction as part of the main lagoon facility is generally considered independent of the rest of the complex, and there is usually an independent access control system to allow the site to be rented out for a limited period of time, allowing surfing or similar activities to be carried out on throughout the paid period. Thanks to the access control system, such an attraction is usually considered independently of the city's beach entertainment complex. All further references apply to the non-surf portion of the city's beachfront entertainment complex and main tropical lagoon facility.

I. Difference from existing locations/activities

As stated earlier, the era when confined spaces such as shopping malls and movie theaters were used for gatherings and meetings is over. By creating and operating an urban beach recreational complex with a tropical atmosphere, including a crystal clear lagoon surrounded by sandy beaches, an incomparable setting is created for a meeting place of the 21st century. Accordingly, urban beach recreational complexes can replace traditional walkways and public parks with urban beach environments where a variety of cultural, recreational, educational and commercial activities can be carried out.

In the case of malls, as mentioned earlier, customer trends have changed and customers are spending more money on experiences such as travel, entertainment and food. This fact, together with the growing trend of online shopping, has led to the closure of many stores and malls around the world. By providing these public urban beach entertainment complexes with artificial crystal clear lagoon as the main facility with a tropical look and feel, and incorporating malls into their surroundings, this solution can contribute to the preservation of the mall business by providing customers with something more than just a shopping mall. point (for example, by providing an unusual and qualitatively new shopping experience). Customers will be able to enjoy spending the whole day in the mall, shopping, eating, relaxing or relaxing in public places (the term spend time is often used to refer to such activities in conjunction with shopping centers). At the same time, customers will be able to use all the additional facilities and enjoy a day at the beach with a tropical environment. This approach is unparalleled and is expected to have a significant impact in this market, where successful mall projects will include such urban beachfront recreational complexes containing entertainment, dining and leisure components. Shopping malls must provide unique and memorable experiences that customers will often return for. Therefore, it will be desirable for malls that seek to renew their offerings and become part of the 21st century meeting place to build and implement publicly accessible urban beach complexes in accordance with the principles of the present invention.

In addition, physical activities such as jogging and walking were practiced in enclosed spaces or in vegetated public parks, but there are no examples in the world of a publicly accessible urban beach environment that offers the opportunity to appreciate a beautiful, crystal clear, tropical-style lagoon like tropical seas.

In addition, there has been a growing demand for outdoor weddings in idyllic surroundings and a move away from closed and cramped wedding venues. One popular alternative is tropical beach weddings. Accordingly, a public urban beach designed according to the principles of the present invention can provide a popular location for wedding ceremonies and celebrations.

Other activities and events that are usually held in less attractive locations are concerts, which are held either in enclosed stadiums and arenas, or in open unoccupied areas adapted only for such events, and usually do not have beautiful scenery or environment.

The complex built according to the present invention will create a beautiful environment and include a large number of activities around the main object in the form of a tropical lagoon, which will be associated with it. Characteristic features of the complex may include night lighting, bars and restaurants for meeting friends and family, screens, stages and amphitheaters for various recreational, cultural, educational or sporting events - all this creates an environment in which you can have a wonderful experience and enhance your image. people's lives. In addition, part of the lagoon contains a surf attraction used to provide waves for surfing and fulfill the purpose of surfing.

II. Difference from pools and water parks

It is important to note that these public urban beach entertainment complexes will be very different from traditional water parks. Modern water parks have a completely different concept as their main purpose is to provide slides, rides and water activities for visitors. Such water parks do not provide a tropical environment with the look and feel of a beach, but rather provide visitors with a set of attractions and experiences within the park. On the other hand, the public urban beach entertainment complexes of the present invention aim to provide a main facility in the form of an artificial tropical crystal clear lagoon, allowing various recreational, cultural, sports, educational and commercial activities to be carried out around it. These activities simply cannot exist without the main facility in the form of a lagoon. Therefore, instead of having a water park with several small pools and attractions using traditional swimming pool technology, the urban beach entertainment complex provides a meeting place for the 21st century, allowing a range of recreational, cultural, sports, educational and commercial activities around the main lagoon facility. with beautiful and attractive surroundings.

With regard to the technology used to build and operate the main tropical-style crystal lagoon facility, it is important to understand that traditional swimming pools do not provide the venue for this idyllic beach lifestyle. While a pool may provide a swimmable body of water, it does not provide the key parameters needed to create the look and feel of a beach, an urban beach experience, and the feel of being in a tropical setting.

Additionally, the cost of a water park is significantly higher than the cost of an urban beach recreation center such as described in the present invention.

For example, a water park in South Dakota, comprising three small water features approximately 1,000, 600, and 700 m ² (total 2,300 m ² ) and using swimming pool technology, has an estimated construction cost of about $5,000,000 (counting only three water features and related equipment), while the city's 1.2 hectare (12,000 ^m2 ) lagoon beach entertainment complex will have an estimated construction cost of approximately $1,800,000 (including the main lagoon facility and associated equipment only). It is important to note that these costs do not apply to the surf portion of the lagoon or its design or operation requirements, as such artificial wave generators are usually provided by a third party and are usually installed in the lagoon portion of the main facility. Such a surf area is usually fenced off or restricted in a way that prevents people from the rest of the lagoon from accessing the surf area.

In addition, the cost of operating said water park is estimated at $20,000 per month, including electricity and chemicals, while the cost of operating said

- 8 041087 the 1.2 hectare main lagoon facility (not including the surf section) will be valued at $4,000 per month inclusive of electricity and chemicals. This data is based on a study by Stantec, an independent engineering firm that designed and built this water park located in South Dakota.

In contrast to traditional public swimming pools, these public urban beach resorts with large man-made crystal clear lagoons offer several advantages, as described in the following table. 1.

By creating these public urban beach entertainment complexes and embodying the beach lifestyle anywhere in the world in a cost-effective and sustained manner, value can be created and the overall appreciation of adjacent or adjacent sites can be increased. In addition, the creation of these complexes can thus increase the value of nearby buildings, houses and any other sites and objects located near the complex. The score can be even higher if there are commercial or residential buildings that directly overlook the city's beachfront recreational complex and its tropical-style crystal clear lagoon, thanks to the beautiful scenery and the feeling of being on the coast. An urban beach recreation center can also create and add value to the entire area where it is located, as it adds value to the city by creating a beach lifestyle close to residences.

III. Parameters of the city beach entertainment complex and the lagoon

According to the present invention, an artificial public urban beach entertainment complex is provided, containing the main object in the form of a large tropical-style crystal clear lagoon with a tropical appearance and atmosphere.

In addition, at least a portion of the main tropical style lagoon facility includes at least one wave generating means providing a surf area in at least a portion of the lagoon. Therefore, the lagoon will be divided into a surfable part and a non-surfable part, with the surfable part usually containing the wave making equipment and enclosing the area where the surfing waves are created. By positioning the artificial surf wave generator in an appropriate area of the lagoon, the resulting surf waves can be used for surfing, boogie surfing

- 13 041087 and body surfing among other activities. The artificial surf wave generator is configured to generate surf waves using the same water from an artificial crystal clear lagoon and is installed in a portion of the lagoon. In addition, preferably such part of the lagoon for creating waves for surfing and surfing does not exceed 50% of the total area of the lagoon. Creating such surf waves based on the configuration of such surf areas in the main lagoon facility can also move water in beach areas, recreating the natural small and aesthetic wave movement.

The non-surf portion of the tropical style crystal clear lagoon according to the urban beach entertainment complex of the present invention has a bottom, perimeter and minimum surface of 8000-10000 ^m entertainment complex. The use of smaller lagoons would not convey a tropical setting. Instead, it would resemble a traditional backyard or hotel swimming pool that doesn't provide the necessary conditions for immersing yourself in an idyllic beach lifestyle.

Additionally, the tropical style lagoon has a maximum surface area of approximately 200,000 m ² because even larger surface areas do not provide the desired appearance and atmosphere. For example, when the area of the lagoon exceeds 200,000 m ² and a person looks at the opposite shore, he or she may not see the opposite shore area along with its additional establishments and playgrounds. Thus, the desired feeling of a holiday on the coast, as described in the present invention, is not created. Those skilled in the art will appreciate that the lagoon can be positioned and configured to be longer than wide. In this case, you can achieve large sizes, while still achieving the desired appearance and atmosphere.

Consider Fig. 1, which shows a typical urban beach recreational complex 1 with a main facility in the form of an artificial lagoon 2 in a tropical style. The lagoon 2 comprises at least one shallow beach area 3a, a swimming area 3b and a water sports area 3c, each located within a large tropical style artificial lagoon 2. In FIG. 2 shows a schematic side view of one embodiment of the beach edge 3 a with a gradual increase in depth.

As shown in FIG. 1 and 2, the bathing area 3b is located adjacent to the edge 3a of a beach with a gradual increase in depth, the edge with a gradual increase in depth preferably resembles a natural gentle slope of a tropical beach or natural lake. The edge with gradual increase in depth creates an inlet to the lagoon, which usually starts just above the average water level 4a, passes through the average water level around the perimeter of the lagoon 4b and continues to drop below the average water level to the center of the lagoon 4c. The slope of the edge with gradual increase in depth, represented by the angle α (and numbered 5 in Figs. 2 and 3), is formed by the angle between the horizontal line (usually parallel to the mean water level) and the sloping beach entrance. Preferably the angle is between 5 and 30%. This range generally resembles the natural edges of beaches with gentle slopes and provides people in beach area 6 and swimmers with a free and good view of the large and crystal clear water surface.

Also, the bathing area 3b includes a local disinfection system that provides an increased concentration of chemicals in such an area. The local disinfection system comprises a metering outlet positioned and configured to deliver disinfectant chemicals into the body of water in the bathing area. The local disinfection system is best seen in FIG. 3, which shows a perimeter chemical application system 7a and a bottom chemical application system 7b. The chemical application system includes one or more systems selected from the group consisting of nozzles, atomizers, nozzles, piping, and inlets.

The chemical application system can be located along the perimeter of the lagoon and is usually limited to the swimming area, whereby the main exposure to disinfectant chemicals occurs mainly within the swimming area. The chemical application system may preferably be located on the bottom of the swimming area and include a plurality of metering outlets, with the metering outlets located on the bottom of the lagoon within the swimming area, whereby the main exposure of disinfectant chemicals is mainly within the swimming area. There may also be combinations of a perimeter chemical application system 7a and a bottom chemical application system 7b. It will be understood that the amount and specific location and configuration of the selected chemical application system is best determined on a case-by-case basis, considering the potential number of bathers, the volume of water, the flow of water in the swimming area to the rest of the tropical style lagoon, among other things.

As also shown in FIG. 1, the water sports area 3c has a minimum water depth range that is at least more than 1.5 m and preferably more than 1.8 m.

- 14 041087

This minimum depth allows for water sports that would not be possible in traditional small size swimming pools. The area for water sports, depending on its design and configuration, can have a variety of slopes at the bottom. When the total size of lagoon 2 is between 10,000 and 200,000 ^m2 , a range of water sports can be practiced in the water sports area 3c, such as sailing, boating, canoeing, kayaking, tubing, watersports. skiing (skiing without skiing, skiing without a powered watercraft, jet skiing), flyboarding, paddleboarding, parasailing, rowing, wakeboarding, windsurfing, kiteboarding, kitesurfing, among others. Preferably, for water sports such as water skiing and the like, the size of the lagoon 2 should be approximately 15,000 m ² or more. Also, the artificial wave generator 25 is configured to generate surf waves in at least a portion of the lagoon, referred to as the surf portion 26.

As mentioned earlier, traditional swimming pools located in water parks have a small area, usually in the range of 1000-1500 m ² , with a maximum depth usually less than 1.5 m. beach lifestyle and do not allow for multiple water sports. On the contrary, a crystal clear tropical-style lagoon 2, created according to the principles of the present invention, in the deepest part of the zone 3c for water sports has a minimum bottom depth of 1.8 m - and often in most of the zone 3c for water sports sports depth even more. This makes it possible to indulge in countless water sports with a variety of watercraft that cannot be found in traditional swimming pools.

Consider Fig. 1 and 4, where several possible embodiments of the complex are shown, with similar objects and structures indicated by similar designations. In various embodiments, at least one sandy beach area 6 is provided that surrounds a large, crystal clear, tropical-style lagoon 2, with the sand having a light color reminiscent of a tropical beach. In a preferred embodiment, the colors of the sand are similar to or within the range of the following colors according to the RAL color chart: RAL 9001, RAL 9002, RAL 9003, RAL 9010, RAL 9016, RAL 9018, RAL 1001, RAL 1014, RAL 1004 or similar colors.

The sandy beach areas 6 are typically provided just before the edge 3a of the beach with a gradual increase in depth, located on at least part of the perimeter of the central lagoon, to create a feeling of coming out of the water to the beach. Beach areas 6 and additional recreation areas have a minimum surface area sufficient to support recreational, educational, sports and commercial activities. The beach areas 6 and additional recreation areas have a surface area preferably of at least 2500 m ² , which allows this area to be largely used for various activities such as concerts, performances, screenings, sporting events, as well as other activities. and events.

Also unlike traditional pools, which have hard edges and enclosed shapes, the non-surf portion of the main tropical lagoon facility is preferably designed with curved shapes and rounded corners that are associated with natural waters and beaches, conveying the feeling of being in an idyllic setting. paradise beach.

In addition, in an embodiment of the present invention, at least one part of the urban beach entertainment complex involves the use of trees and plants to create a tropical appearance. In a preferred embodiment, vegetation 8 reminiscent of a tropical setting is located in beach areas or additional recreation areas surrounding or located near the edges of the beach with a gradual increase in depth and/or areas 6 of sandy beaches.

As shown in FIG. 4, the urban beach entertainment complex 1 further comprises a water supply system 9 operatively connected to the water supply network and containing a source, pumps, devices and other suitable fluid channels for supplying fill and make-up water to the lagoon 2. Those skilled in the art will appreciate that devices and conduits for supplying make-up and make-up water to the lagoon include piping, nozzles, sluices, inlets, outlets, and fittings, among other things. The make-up water supply system is preferably positioned and configured to supply make-up and make-up water to the lagoon to continuously maintain a volume of water in the reservoir at a level of at least 80% of the design water volume.

Make-up water should have iron and manganese concentrations of no more than 2 ppm to provide the main tropical-style crystal lagoon facility with suitable water that will not change appearance when cleaned. It will be apparent to those skilled in the art that, for example, water with high concentrations of iron and manganese results in a very noticeable discoloration of the water when it is purified. Also, the turbidity of the make-up water should not exceed 8 NTU to avoid the presence of cloudy water (i.e. such water will not provide a tropical appearance and atmosphere, nor transparency).

- 15 041087

Since the levels of filtration of the main lagoon facility according to the present invention are lower than those used in swimming pools, it is important to control the quality of the inlet water and its compliance with the above parameters.

The tropical artificial crystal clear lagoon 2 according to the present invention is preferably the main object of the urban beach recreational complex 1 and is constructed and maintained with innovative technologies that provide low construction and operation costs. These costs are up to 10 times lower than the construction costs associated with the traditional thick concrete or tile floor used in swimming pools. In addition, these operating costs are up to 10 times lower than those of traditional swimming pools, which require a full volume of water to be filtered 4 times a day.

Due to the low construction and operation costs and at the same time providing the possibility of obtaining aesthetically attractive water with high physical-chemical and microbiological quality, the public urban beach entertainment complex 1 is provided in a cost-effective manner. Accordingly, the method of the present invention makes economical use of sites that are unoccupied, previously had low utilization, or that border or are located near recreational, educational, sports, or commercial establishments, thereby making such sites profitable.

In order to provide an economically viable urban beach entertainment complex, the construction methods for constructing the non-surf portion of the lagoon frame would typically not include a concrete bottom of the type used in the construction methods for swimming pools in most of the lagoon. The construction of a traditional swimming pool requires that the pool frame (bottom and sides) be built from concrete of a specific thickness, typically a minimum of 2 to 6 inches, and which can be reinforced to provide structural stability and resistance based on the type of soil underneath the pool. In addition, such a concrete bottom is usually painted with waterproof paint or tiled, which makes the construction process more difficult and expensive.

On the other hand, the present invention requires that a large portion of the bottom of the non-surf portion of a large main lagoon facility be covered with a flexible plastic material to provide water resistance and sealing properties while providing a different feel than a typical concrete swimming pool floor. Preferably, the bottom surface of a tropical style crystal clear lagoon water sports area is designed such that at least 80% of its surface is covered with a flexible plastic material. The plastic material is selected from the group consisting of polyvinyl chloride, polyethylene, rubbers, polypropylene, among others. In a preferred embodiment, polyethylene may be used. The color of the plastic material varies from pure white to blue or light brown.

The tropical style lagoon floor can be further constructed using different materials to provide additional layers. In one embodiment of the present invention, the bottom of a large lagoon is covered with a mineral layer which creates a substantially stagnant body of water to hold the volume of water. In another embodiment of the present invention, the bottom may be covered with a thin layer of shotcrete less than 6 inches thick.

It is important to note that the technology currently exists to build the non-surf portion of a large, tropical-style main lagoon facility for less than $600,000 (US) per acre (this amount may vary by country, overall size, and specific local variables), and to maintain excellent physical-chemical and microbiological water quality using a minimum amount of chemicals and energy in a cost-effective way. As noted above and by way of comparison, a traditional water park located in South Dakota, USA, containing three relatively small water features with a total area of 2300 m ² , has a total direct construction cost in excess of US$5 million 20,000,000 US dollars per hectare in direct comparison and only considering the surface of water bodies). This data is based on a study by Stantec, an independent engineering firm that designed and built this water park located in South Dakota.

Also, the city's public beach entertainment complex contains a cost-effective purification system that provides water purification technology that uses at least 50% less electricity than traditional centralized swimming pool filtration and disinfection systems. The water treatment technology contains a filtration system having a filtering capacity and filtered water volume at least 50% lower than traditional swimming pool filtration systems that filter the full volume of water 4 times a day.

For example, using traditional pool technology, for a 30,000 m ² lagoon

- 16 041087 with a volume of 45,000 m ³ , the volume of filtered water will be 180,000 m ³ per day (to achieve filtration of the total volume of water 4 times a day = 45,000 mx4 = 180,000 m/day). On the other hand, the preferred water treatment technology of the present invention includes a filtration system that filters at least 50% less than a traditional swimming pool filtration system. Considering the same example, the filtering capacity of the present invention and the volume of water will be a maximum of 90,000 m ³ /day, thereby achieving significant savings in energy and equipment costs.

In one embodiment of the present invention, the main tropical lagoon facility utilizes a modular cleaning system 10, wherein the modular cleaning system includes one or more items selected from the group consisting of a containerized machine room, a framed system, and/or water purification equipment. In a preferred embodiment, such a modular cleaning system is located and made with the possibility of online connection. This facilitates its connection with other elements, equipment, systems, pipelines and structures. In another embodiment of the present invention, the modular cleaning system 10 is portable and can be deployed and installed on site in a short period of time. As another advantage, the modular cleaning system 10 can be operated on a temporary basis, depending on the time of year, its configuration, and need. An example of a preferred modular cleaning system that can be used in conjunction with the present invention is a group of containers made to house different systems and equipment, which can be made locally or sent from other cities or even countries.

In the preferred embodiment of the present invention, the economical treatment system does not produce a noticeable chemical odor in most of the lagoon, unlike traditional swimming pools having a constant residual chlorine level of 1 ppm in full water. Since much of the lagoon is virtually free of any noticeable chemical odor, this helps achieve the goal of providing the look and feel of an idyllic beach with white sandy beaches reminiscent of Caribbean beaches.

In another embodiment of the present invention, the water treatment technology for operating the main tropical lagoon facility must use at least 50% fewer chemicals than a traditional swimming pool disinfection system that requires a constant chlorine level of at least 1 ppm, in the total volume of water, for example, according to the regulations for traditional public swimming pools from the CDC (United States Centers for Disease Control and Prevention), Rule 64E-9 from the Florida Department of Health and Title 22 - Title 4 - Chapter 20 of the California Administrative Code, in addition to other things.

In addition, the tropical style lagoon main object 2 may preferably have natural wave motion on the surface due to its large surface. The horizontal extent of the lagoon 2 in the direction of the wind can create a wave generation region, whereby the wave generation region is a horizontal extent along an open water surface that is blown by the wind and generates waves. Therefore, the appearance of the waves in a tropical style lagoon achieves a natural appearance, since the waves are similar to those of the sea and are very different from the waves created in traditional small swimming pools. Depending on the horizontal extent, parallel to the wind blowing over the lagoon, the waves created in the lagoon will be higher and similar to the movement of water in the sea. Wave height increases exponentially with wave origin and wind speed, an effect that cannot be achieved in traditional small basins. This will be in addition to the use of a surf wave generator in part of the lagoon, which will also create surf waves that will move the surface of the water in the lagoon.

In one embodiment of the present invention, the tropical-style crystal clear lagoon operates in a substantially closed loop. In this embodiment, the volume of water is not substantially renewed by recycling with a water source (eg, a well) and/or an open body of water or river.

In one embodiment of the present invention, the crystal clear tropical style lagoon has a minimum vertical transparency of 1.2 m to resemble tropical seas with crystal clear waters when the surf generator is not in operation. This depth allows you to create rich color with crystal clear water, while the tropical style lagoon bottom 11 allows you to provide such rich color and tone due to the reflection of the sun from the bottom and due to the transparency of the water.

There are new and innovative ways to build and maintain large bodies of water with excellent physical-chemical and microbiological water quality and high transparency for various applications, which are protected by US and worldwide patents, such as those described and shown in the following issued US patents: US 7820055, US 8070942, US 8062514, US 8790518,

- 17 041087

US 9708822, US 9470007, US 9080342, US 8465651, US 9062471, US 8753520, US 9957693 and US 9470008.

Each of the above patents is incorporated herein by reference and forms part of it.

Such innovative methods, systems and devices have very low construction cost, very low operating costs due to the use of minimal amounts of chemicals and energy to maintain water quality, and alternatively can be used to build and/or maintain large crystal clear lagoons with tropical appearance and atmosphere. These proprietary methods, systems and devices can be used to build and/or maintain a large crystal clear lagoon 2 using all or some of the technologies or details described in such technologies.

The aforementioned incorporated patents describe various large lagoon water treatment operations and processes that provide efficient and cost effective water maintenance. Although it is worth referring to such patents for detailed descriptions, the following is a brief description as a typical method of maintaining water in a public lagoon. Firstly, the process of purifying and filtering water requires collecting water and storing this water in a container having a bottom that can be thoroughly cleaned by a suction device. Secondly, over a period of 7 days, the process requires the water in the tank to be purified by periodically adding disinfectants to said water to obtain an redox potential (ORP) of at least 500 mV for a period of time depending on the temperature of the water to be treated. Thirdly, the method requires activating the operation of the mobile suction device in order to suck a part of said water into a container containing settled solid particles, so that the thickness of the settled material does not exceed 3 mm. Finally, the method requires filtering said portion of the water sucked in by the mobile suction device and returning the filtered water to said container. These processes use at least 50% less filtration capacity and filtered water volume compared to a traditional swimming pool filtration system that needs to filter the full volume of water 4 times a day.

It is important to mention that the previously mentioned proprietary technologies have been used in real estate developments with completely different concepts and configurations. In addition, such improvements do not involve mass public use and do not create a meeting place for the 21st century. Instead, real estate development applications are very different, as such lagoons are intended for owner and resident use, do not have controlled public access (such as entry fees) for large-scale use, and cannot be located in areas with a high concentration of urban population. Therefore, they cannot create a 21st century meeting point with surrounding venues and facilities such as restaurants, amphitheaters, stages, kiosks, rental shops, shopping malls, gyms, walking areas, bars, coffee shops, among others. Accordingly, the real estate model is quite different. However, if there is a real estate, hotel, or private residence improvement near a public urban beach entertainment complex or in one area on the perimeter of a main tropical lagoon facility that has private access to such an area, the principles of the present invention require at least one public access area that is separate from such enhancements and has controlled access for public use as a mixed use.

Therefore, as mentioned in this whitepaper, swimming pool technologies cannot be scaled to large bodies of water. For large bodies of water, other technologies are used, such as those used in lagoons for surfing, aesthetic pleasure or decoration, but which do not achieve either the crystal clear water or the water quality characteristics of the present invention and would not be able to provide the urban beach entertainment complex of the present invention. .

In one embodiment of the present invention, evaporation control chemicals are added to the lagoon water to reduce natural evaporation by up to 50% of natural evaporation rates. It should be understood that chemicals must be approved for use in recreational waters. Examples of preferred evapotranspiration chemicals include alcohol-based evaporative chemicals or silica-based evaporative chemicals that create an invisible layer on the surface of the water and therefore reduce evaporation by preventing direct contact between the water surface and the surroundings. air. Adjustment chemicals work at different temperatures and are able to withstand the effects of wind. The evaporation control chemical must be NSF approved for use in recreational waters, either NSF 50 (swimming pool chemicals) or NSF 60 (drinking water chemicals). An example of a preferred evaporation control chemical is Heatsavr® Crystal Lagoons Formula, manufactured by Flexible Solutions of Canada. Such

- 18 041087 the chemical can be added manually, using a system 9 for adding water and/or a modular cleaning system 10.

The urban beach entertainment complex also includes at least one access control system 12 that preferably restricts and controls user access on a daily basis to at least a portion of the complex. The access control system is located in at least one part of the physical enclosure 16. The access control system 12 includes one or more access control areas 13 that contain a control system 14 to provide controlled passage of the public through such a post. Such a control system may include gates, turnstiles, biometric systems, access card readers, security fences, biometric systems, among others. In a preferred embodiment, the control system comprises a gate with a turnstile. Additionally, in FIG. 5 shows sequence 15 of steps 15a-15c, allowing, after payment of a fee, controlled access to at least a portion of an urban beach entertainment complex.

In FIG. 4 shows a diagram of one embodiment according to the present invention, where a physical fence 16 limits the entry of people into an urban beach entertainment complex 1 and provides access to the complex through the access control posts 13.

The public will access the city beach entertainment complex through the access control posts 13, since the remaining boundaries of the city beach entertainment complex must be physically fenced off to prevent uncontrolled access.

In FIG. 11 shows one embodiment of an access control system 12 depicting a point of sale 24 used when people pay an entrance fee. In another embodiment, people may use their pre-purchased tickets or season passes to access at least a portion of an urban beach entertainment complex and may not be required to pay an entrance fee on the spot. In the depicted embodiment, a person purchases a ticket on the spot, then optionally goes through security 23 and then uses one of the access control posts 13 containing at least one control system 14, in this case a turnstile, to access the city beach entertainment complex.

The access control system is designed to provide public access to the complex and requires the use of a special fence. Such fencing forms a physical boundary structure implemented at the boundaries of the urban beach entertainment complex or part of it, access to which will be controlled. The fence may include one or more combinations of elements selected from the group containing fences, walls, ditches, natural vegetation, buildings and parts of buildings, or other types of fences to prevent public access to the urban beach entertainment complex 1 through any location other than posts with system 13 access control. It should be understood that the fences may vary from complex to complex, depending on the location and existing structures (if present). It should also be understood that one-way emergency exits and/or exits may be provided in fence areas, which typically trigger warning horns and sirens.

Preferably, the access control system is configured to provide access to the urban beach entertainment complex 1 or part of it to at least 500 people per hour. For example, for an urban beach entertainment complex 1 with a total area of 40,000 m ^2, the access control system 12 may include two different access control posts 13, each of which has at least four control systems 14, such as turnstiles, allowing the public to pass through such turnstiles and receive access to the urban beach entertainment complex with a total speed of at least 500 people per hour. Preferably, at least one of the control systems 14 and one of the access control posts 13 can be opened or closed depending on the needs of the public.

The urban beach entertainment complex also includes at least one ancillary facility selected from a group of commercial, recreational, educational, cultural, residential and/or sports facilities surrounding the main facility in the form of a tropical-style artificial lagoon to provide a variety of activities. activities inside the urban beach entertainment complex. Ancillary facilities 17 are selected from the group including, but not limited to, restaurants, shopping malls, exhibition centers, gyms, stores, sports facilities 17e, and educational or cultural institutions, depending on their configuration. Auxiliary objects 17 are shown in FIG. 1. Such support facilities and sites may be provided by a third party.

Preferably, the urban beach entertainment complex further includes at least one coastal amphitheater with stages and/or spaces for holding and/or displaying various events, educational activities, concerts, cultural events, sports events and similar activities. Also, the urban beach entertainment complex may include at least one large screen for displaying movies, sports events, conferences, broadcast simulcasts, live broadcasts, e-sports events, educational activities, events, and similar content.

The urban beach entertainment complex of the present invention may also include a lighting system 18 (best seen at the perimeter of lagoon 2 in FIG. 4) whereby the tropical style lagoon is illuminated to allow use at night or under enclosed structures. The underwater lighting clearly defines the perimeter of the lagoon 2 and also illuminates the water with underwater light sources, creating a whole new aesthetically pleasing look for a beach night setting. The lighting system 18 comprises underwater light sources in the form of LED strips or underwater point light sources. The lighting system can be used around the perimeter of Tropical Lagoon 2 or only in certain parts of the lagoon. One embodiment is shown in FIG. 4 where the lighting system 18 is used on part of the perimeter of the lagoon 2.

Moorings 19 (best shown in FIG. 4) can be provided within a crystal clear lagoon, which is not possible in swimming pools as tropical style crystal clear lagoons allow for water sports and require moorings to access the deep parts of the lagoon. In FIG. 4 shows the use of berths 19 within tropical lagoon 2.

IV. Description of the method

As shown in FIG. 6, the method 20 of the present invention, including steps 20a20g, provides a method for efficiently utilizing facilities and land that are unoccupied, have a low utilization rate, or are adjacent to or adjacent to recreational, educational, sports, or commercial establishments by providing publicly accessible urban beach entertainment. complex with the main object in the form of an artificial crystal clear lagoon in a tropical style. The method provides an opportunity to generate income by allowing the creation of public urban beach entertainment complexes, which must be located on low-use or unoccupied sites with a certain population density and access infrastructure, in order to create a meeting place of the 21st century.

The method of the present invention includes finding and identifying a low utilization or unused site, with site selection being a key part of the method. Sites that may be selected for this purpose include unoccupied land, low-use land, and sites bordering or adjacent to various establishments such as recreational, educational, sports, and commercial establishments.

Recreational, educational, sports and commercial establishments that may have bordering areas of low utilization include event arenas, amusement parks, water parks, museums, stadiums, golf courses, indoor clubs, zoos, aquariums, shopping malls, university towns, casinos, cruise ship ports, racing tracks, racetracks and Olympic venues, among others.

The site in accordance with the method of the present invention should preferably have a minimum surface area of 16,000 m ² to create a public urban beach entertainment complex and be strategically located so as to have a minimum population in the surrounding areas of 500,000 people within a radius of 50 miles.

In FIG. 7 depicts an exemplary population density map from which a desired area in combination with an area that is vacant and/or underutilized can be determined by analyzing the population density in a neighborhood within a 50 mile radius of the location of the potential vacant and/or underutilized site. section 21. In FIG. 7, the population density is indicated by different color and/or saturation of the pattern in the figure, with the selected area surrounded by a dotted circle indicating a radius of 50 miles, and in this case, a population analysis was carried out, and it was determined that such an area had a population density of at least at least 500,000 people.

The urban beach entertainment complex and the method of making efficient use of land of limited use according to the present invention aims to bring a new way of life and transform urban centers into a meeting place of the 21st century, completely changing urban centers that have a large population in the surrounding areas, and providing these people the opportunity to immerse themselves in the tropical lifestyle close to their homes. These city centers are targeted at the population in the surrounding areas in close proximity, with the goal of a high frequency of people returning to the city's beach entertainment complex for positive experiences, shopping, cultural events, movies, water sports, dining or dinner, coffee, or other activities. With a high probability, the creation of such complexes can be important, since such urban beach entertainment complexes are expected to have significant attendance.

Several predictable implementations of the effective use of some of the aforementioned establishments with the present invention are shown in FIG. 8A, 8B, 9A, 9B, 10A and 10B. In FIG. 8A and 8B show one embodiment according to the present invention, which is a race track, with a large area of low utilization within the race track 21a. The low utilization area shown in FIG. 8A has been converted as shown in FIG. 8B into a beautiful area with tropical style crystal clear lagoon 2 as the main facility, forming an urban beach entertainment complex 1. In FIG. 9A, 9B, 10A and 10B show another embodiment according to the present invention, where part of the parking lot 21b shown in FIG. 9A and 10A has been converted into the urban beach entertainment complex shown in FIG. 9B and 10B, containing a main facility in the form of a tropical-style crystal clear lagoon 2.

It should be understood that access infrastructure, such as roads and public transport, must be present to transport visitors to the complexes (ie, to be able to reach the complex at a reasonable cost and within a reasonable period of time).

Additionally, the site may preferably have a predetermined source of water and sufficient availability for its use. The type of water can be fresh water, brackish water, salt water, or sea water, depending on availability. The water sources may be selected from the group consisting of sea, ground water, potable water, surface water, wells, or other types.

The water source must not be contaminated with industrial waste that requires extensive industrial pre-treatment and cannot be removed by simple and traditional pre-treatment methods such as oxidation or filtration processes. For example, the water source should preferably not be contaminated with industrial water residues such as aluminum and hydrocarbons. Large scale industrial pretreatment systems typically require the use of large sumps which also provide an industrial appearance that conflicts with the tropical beach feel that is the aim of the present invention.

Once a site has been selected, the method includes developing a public urban beach entertainment complex 1 with a main facility in the form of a large artificial tropical crystal clear lagoon 2. Lagoon 2 preferably has the look and feel of tropical seas and beaches, thereby creating an idyllic beach feel. The tropical look and feel is all about providing the feeling of being in an idyllic setting, with a large body of water and a beach area simulating, for example, the feeling of being in the Caribbean.

The city's public beach entertainment complex contains an economical purification system that provides water purification technology that uses at least 50% less electricity than traditional centralized swimming pool filtration systems. The water purification technology includes a filtration system having a filtering capacity and a volume of filtered water at least 50% lower than conventional swimming pool filtration systems (eg, which filter the entire volume of water 4 times a day). In addition, in one embodiment of the present invention, the water treatment technology for operating a tropical style lagoon main facility must use at least 50% fewer chemicals than a traditional swimming pool disinfection system (e.g., which requires constant maintenance of chlorine levels, constituting at least 1 ppm, in the entire volume of water). Therefore, there is less chemical smell in lagoon 2 than in a traditional pool.

City beach entertainment complexes can be located, for example, in public parks. However, there must be a physical barrier and/or fence to provide controlled public access to the urban beach entertainment complex 1 or part of it, such as the control system and posts 13 access control.

Additionally, for efficient use of the restricted area, facility, or land, the method includes charging an entrance fee to provide access to at least a portion of the urban beach entertainment complex. Such fees may be charged prior to entering the City Beach Entertainment Complex, or may be charged locally based on availability and other factors such as demand and overall attendance, among others. Fees may vary depending on age, number of people in groups, time of year, or other factors. In addition, the fee may be based on different seasonal, monthly, weekly or other passes. It should also be understood that electronic tickets using cell phones and other devices may be used in addition to printed materials and/or cards. It should be understood that there may also be seasonal passes (such as week, month or year passes) that can be purchased online or before visiting the city's beach entertainment complex.

In one embodiment of the present invention, the main lagoon facility and surrounding facilities may only be accessible to the public upon payment of a pre-entry fee. However, in some embodiments, it may be desirable for at least a portion of the entertainment areas, cafes and restaurants to be available to guests without paying a fee.

In these embodiments, visitors using the beach and water sports areas may be charged for access to these areas.

Therefore, the method includes the ability to generate income for sites with low utilization or not currently used, such as unoccupied land, land with limited use, and land adjacent to or located near establishments such as recreational, educational, sports and commercial establishments. , by creating an innovative beachfront entertainment complex with a large tropical crystal clear lagoon as the main facility, and which provides controlled access and which charges a ticket/entrance fee to the site.

Based on the population within a 50 mile radius and the magnitude of the demand that the urban beach recreation complex will create, a minimum of 100,000 people annually, preferably 500,000 people annually, and most preferably more than 1,000,000 people annually, are expected to visit the tropical setting. Visitors are expected and planned to be primarily from the surrounding area and are expected to revisit the city's beach entertainment complex many times. With the beautiful and relaxing nature of this beach-like setting that allows for relaxation, shopping, water sports, swimming, eating, among other activities, a large annual attendance is expected, targeting a larger percentage of the neighboring population, as well as an additional percentage part of the tourists who will visit public city beach recreational complexes.

It has been estimated that by creating a complex using the principles of the present invention, it is possible to achieve an attendance of such an urban beach entertainment complex of the order of 100,000 to 1,000,000 and up to 6,000,000 people per year. Based on the market and socio-economic status of cities, admission fees are expected to be between US$5 to US$150, preferably US$10 to US$20, generating an annual direct income of US$1,000,000 to US$12,000,000 from ticket sales alone.

Therefore, for example, an urban beach recreation center with a 16,000 ^m2 tropical lagoon main facility with an annual attendance of 500,000 people and a $15 admission fee could generate $7,500,000 in direct ticket revenue while while the total construction cost of the main lagoon facility would be in the order of US$2,400,000 and the annual operating costs would be less than US$100,000 per year (including chemicals and electricity).

V. Example of a shopping mall

As another predictable example, the method of the present invention can be used in the shopping mall industry, where a part of the parking spaces located in the shopping center, which currently has a low utilization rate, can be converted into an urban beach entertainment complex. Based on the project evaluation, three scenarios were obtained, including a conservative scenario, a baseline scenario and an optimistic scenario, where the income and profit associated with the construction, operation of the urban beach entertainment complex and paid access to it are presented in Table. 3.

Table 3

Description Conservative Base Optimistic Attendance 250,000 people per year 500,000 people in year 750,000 people per year Admission ticket $30 $30 $30 Gross income in 1-4 years $30,000,000 USA $60,000,000 USA $90,000,000 USA Internal rate of return 67.3% 129.8% 172.1% Profitability b costs 32% 68% 105%

The scenarios listed in Table. 3 do not consider an event center, large restaurant areas or sports facilities, but consider ancillary facilities such as a beach center with rental shops. Therefore, the rates of return are expected to reach significant levels, thereby creating a very attractive market and investment by improving the efficiency of land of limited use, in this case the parking lot of an existing shopping mall.

It is important to note that, all over the world, some areas have been modified, for example by adding sand at the border of natural rivers with poor water quality. With this improvement alone, the number of visitors amounted to more than 500,000 people annually. Examples of such locations include Luján Beach in Mendoza, Argentina and Encarnacion in Paraguay. But neither of these two examples of public spaces created a meeting place for the 21st century, where an urban beach entertainment complex with a main facility in the form of a tropical-style crystal clear lagoon is equipped with ancillary facilities, while containing beach centers, rentals, stages and similar facilities and places for pleasant pastime day and night with family and friends. It is also believed that such places do not have as good an opportunity for profit as the method according to the present invention, which, based on calculations and economic estimates, has an internal rate of return of up to 172% and even higher, depending on the specific scenario. The ability to cost-effectively transform land of limited use, such as low-use sites or facilities that border or are located near recreational, educational, sports or commercial establishments, into a highly profitable business by creating an urban beach entertainment complex has not previously been seen and will have great social and economic benefits.

The urban beach entertainment complex and the method for making efficient use of land of limited use according to the present invention also contemplates the incorporation of entertainment and commercial sites in the urban beach entertainment complex through the rental or brokering of space, facilities, services such as food and beverage sales, activities. or equipment. Therefore, based on research, it is expected that the previously calculated income from direct access fees can even double with the help of such ancillary businesses.

Some venues surrounding the main tropical lagoon-style facility contain natural and coastal amphitheaters with stages and spaces for concerts, e-sports and other events, large screens for showing films, sports events, conferences, educational events, live events , exclusive live broadcasting of shows and other events, and others, unique coastal centers and venues for events such as conferences, weddings, trade shows, fairs, meetings and others, sectors for the sale of food and beverages with permanent or temporary facilities, such as bars, restaurants, food trucks, coffee houses and others, sports sectors such as gyms, jogging tracks, football fields, tennis courts and others, shopping malls and facilities, kiosks, rental offices for coordinating activities or equipment rental.

An amphitheater section 17a can also be created within an urban beach entertainment complex, with the amphitheaters 17a accommodating a large screen 17b and/or stage 17c for various events (see FIG. 1).

Additional activities that can be performed directly or indirectly from the large tropical-style crystal clear lagoon include floating water parks containing Wibit® or Aquaglide® objects, banana rides, holographic imaging displays, water performances, floating stages, among others. .

Various activities and performances may be performed live on site or may be shown and/or streamed via a large screen designed to be seen by a predetermined number of people. Such activities and performances include concerts, performances such as water ski shows, drone light shows, water climbing walls, synchronized swimming, ceremonies, feature films, television series, documentaries, sports including beach volleyball, e-sports, games and gaming events, competitions, including drone races, streaming of live or pre-recorded material, among other things.

Beach entertainment complexes may be primarily outdoors or may be wholly or partly covered by domes or structures that allow year-round use and activities in highly seasonal areas and that allow winter activities to take place inside the domes. Such domes may be structural or inflatable and may be positioned and constructed to cover all or part of a tropical lagoon.

Additional sites made within the beach entertainment complex, including
