Abstract
The Parkland Sewerage System is a sustainable localised sewerage and sewage
treatment system enabling development of smaller lots with no on-site sewage
treatment in areas not connected to mains infill sewerage. It is adaptable for
development of residential, retail or commercial uses and also for groups of
units or small homes. The system provides a higher level of environmental
protection than onsite treatment and is adaptable to meet the environmental
demands of each development location. Importantly, the system offers full
control of maintenance by authorities without the need to access owners'lots.
It is designed to include an internet enabled remote monitoring system, which
also has scope to add a billing system to lot owners. The Parkland Sewerage
System provides an alternative to onsite systems and mains infill sewerage,
with lower costs of installation and operation.
Description
[001] The Parkland Sewerage System has been developed to offer an alternative to on-site sewage treatment in most areas of Australia not serviced by reticulated mains sewerage. The present invention is a method of combining sewerage and sewage treatment apparatus in a novel way to provide a more environmentally friendly local self-contained system. Notably the Parkland Sewerage System enables subdivision of land lots with no on-site sewage treatment, which makes it possible to develop smaller lots for residential, retail and commercial uses as well as units and retirement villages in country towns or most places without mains sewerage. This is something not yet available to developments outside mains sewer areas in Australia. The said system achieves a high level of environmental protection and offers adjustable treatment levels to adapt to the surrounding environmental needs of each development location. The said system solves a major existing problem for authorities, as there are no owners' onsite systems to inspect and monitor. It allows the water authority or management body to retain complete control over every aspect of maintenance and remote monitoring without the need to access owners' lots. Overall, these factors point to a considerable saving in government expenditure.
[002] For many decades across Australia the ageing and growing population has increased demand for new home lots. In country towns ever rising costs have considerably slowed authorities' attempts to provide sufficient infill sewerage to meet the demand for small town lots. Further, the need for controls to protect the environment and the challenges of various soil types pose even more complex problems. Policy decisions regarding methods of sewage treatment have become increasingly difficult with the need to balance environmental outcomes, health issues and the rising demand, particularly in country towns.
[003] Most attempted solutions have limited minimum lot sizes to 4000 square meters. Much of these, under more recent regulations, now include onsite sewage treatment and irrigation fields. This in turn renders much of each lot unusable for trees, sheds, home extensions, pools, vehicles and the like. Further, the lack of lots smaller than said size in country towns has prompted sizeable population movement from country towns toward cities and large towns to find smaller town lots, which further inflates property prices. A large percentage of people whether young, old or disabled, do not have the time or ability to manage 4000 square meter lots, hence the trend to move to cities. The social repercussions over decades have caused far-reaching financial and personal problems for a significant part of the Australian population, which warrants priority for a practical solution to be found.
[004] Some attempted solutions have tried various onsite sewage treatment forms, but this has not sufficiently addressed the needs of the industry. There still remain many unresolved problems surrounding uncertain control of servicing sewage treatment systems under owners' responsibility, as well as the high costs and logistics of implementing a satisfactory system of monitoring and enforcing maintenance.
[005] In view of the above, it would be advantageous to invent a system that addresses a practical balance of solutions to the above problems or that provides a useful commercial choice.
[006] Any references to other methods, apparatus or documents are not to be taken as constituting any evidence or admission that they formed or form part of the common general knowledge.
[007] This summary is provided to assist understanding of the nature, operation and purpose of the invention in a simplified form. Further more specific information will be found in the detailed description section of this disclosure.
[008] It should be noted that any application of this invention falls within the scope and regulations of applicable Australian Standards, the Sewerage Code of Australia and other accepted practice governing the installation of sewerage systems for the disposal of sewage. It should therefore be clearly understood that any application of this invention should be subject to approval by the governing authorities.
[009] In a broad form the invention conveys sewage from each of small groups of multiple residential or commercial lots to treatment facilities in a separate parkland lot in new subdivisions. This opens the way to an exemplary solution for authorities to achieve full control of servicing of said treatment and sewerage facilities without the need for reliance on individual home owners or access to residential lots.
[010] In one exemplary aspect of the invention reduced environmental impact is achieved by the replacement of many individual lot onsite treatment facilities with one fully serviced treatment system connected to these lots.
[011] In a further improvement, the invention removes the need for authorities to monitor individual onsite systems with resulting cost and time savings to the authorities.
[012] It is envisaged that the invention would connect from small groups of residential lots to each nearby parkland lot. The actual number of lots in each group would be determined by local topography, soil types, lot sizes and regulatory planning guidelines. Larger developments would typically group lots so that landscaped small parklands become a pleasant aesthetic feature to enhance the community.
[013] Importantly, the parkland lot location enables more precise specification of the sewage treatment facilities. In a similar way, accurate planning of components of the invention such as pumps, gradient and access manholes can be more efficient as sewage load is more reliably calculated based on the number of lots and buildings be serviced in each group.
[013a] Further, said sewage treatment facilities can be tailored to suit the demands of environmental issues such as proximity to water table, rivers, soil types and topography. The level of aerobic and anaerobic treatment may also be adapted accordingly. Indeed many advances have been made in recent years using different bacteria strains to achieve higher levels of contaminant removal. In addition, it can be decided to what level waste products can be recycled and wastewater reticulated.
[014] Beneficially for each lot owner, the new invention does not require on site treatment, wherein large areas are set aside on each lot to accommodate irrigation fields or leach drains. This allows the owner more space to construct improvements, plant trees or drive vehicles and the like.
[015] Another exemplary aspect is that smaller residential lot sizes may be planned in new subdivisions because individual lot onsite irrigation fields are not a feature of this invention. This factor helps meet demand for smaller lots in country towns and contributes to the solution for reducing population movement toward cities. This in turn assists in growing both population and business in country towns.
[016] It should be noted that any one of the aspects mentioned above may include any of the features of any of the other aspects mentioned above and may include any of the features of any of the embodiments described below as appropriate.
[017] Preferred features, embodiments and variations of the invention may be discerned from the following Detailed Description which provides sufficient information for those skilled in the art to perform the invention. The Detailed Description is not to be regarded as limiting the scope of the preceding Summary of the Invention in any way. The Detailed Description will make reference to a number of drawings as follows.
[018] Figure 1 shows a small example of the invention. A new land subdivision of residential lots wherein a larger separate parkland lot is set aside to accommodate a mostly below ground level sewage treatment facility and reticulation field. It should be noted that a choice can be made concerning the size and type of treatment facility based on the number of lots to be serviced, local environmental demands and required load calculations. Figure 1 also shows vehicular access to the parkland lot for maintenance purposes. This enables the water authority to retain control over servicing requirements. Each residencial lot is provided with a connection point to a suitable septic tank located just outside the lot boundary, which then connects via a branch sewer to the parkland lot sewage treatment facility.
[019] Figure 2A shows a larger residential land subdivision with every lot indicating the position of onsite sewage treatment facilities. This is part of an actual existing development using onsite sewage treatment. It shows a concentration of sixty five onsite septic treatment systems in a small area. The authorities do not have control of servicing. Plans to monitor such servicing are yet to be introduced. There are obvious long-term ramifications for the environment here.
[020] Figure 2B illustrates application of the invention on the same estate as Figure 2A. The number of sewage treatment facilities are reduced from sixty five to five in the same area. All are in parkland lots and able to be regularly serviced under the control of the authorities. This preferred embodiment of the invention would enable costs for such servicing to be billed to lot owners in a similar way to the practice adopted currently for sewerage rates on properties connected to mains sewerage. The cost of so doing would be far cheaper to the lot owners and authorities than servicing and monitoring existing onsite systems.
[021] Figure 3A shows a typical example of a new residential lot under current regulations in a non-sewered area with onsite sewage treatment facilities.
[022] Figure 3B shows the same new lot, wherein the present invention is used without onsite sewage treatment. As treatment apparatus is located entirely outside said lot, servicing is completely under the control of the authorities. Without onsite treatment the lot may be planned for a smaller size. The owner has more scope to build on a much larger percentage of the lot thereby increasing both the practical uses and esthetic appeal. Without reticulation fields the lot also offers improved health considerations.
[023] Figure 4 shows a typical example of a two chamber septic tank feeding to a pumping tank. It is a preferred embodiment of the invention for the developer to include a septic tank of more than adequate size in the branch sewer line just outside the boundary of each residential lot to facilitate servicing by the authorities independent of the lot owners.
[024] Figure 5 shows some examples of the various components to be incorporated into the sewerage system of the invention. Due to the many variables in each subdivision layout comprising topography, gradient, soil type, sewage load, number of lots serviced and the like, it is appreciated there will be many different configurations. Indeed different authorities may have varying guidelines for which the present invention may be adapted.
[025] Figure 6 shows two versions of manholes with connections. Installations will vary as explained in Figure 5. One particular advantage of the invention is planning calculations can be very efficient when the invention is to be incorporated in new subdivisions because the load of sewage and number of residences will be known in advance.
[026] Figure 7 introduces the fiexible nature of the invention. A common type of development is encountered, wherein a small infill lot between two existing roads is rezoned for town lots. In this situation, the invention may be adapted so that connection to the sewerage system is located at the rear of each lot, thereby allowing a parkland lot to be created between the two rows of lots.
[027] Figure 8 refers to the many opportunities available to adapt the invention for use in small or large commercial developments. In this small embodiment, two groups form eight shops, with ample car parking space, rear delivery access and attractive parkland outlook from all shopfronts. This is combined with easy servicing access for sewage treatment facilities and low quantities of sewerage system components.
[028] Figure 9 depicts the invention applied to an embodiment for a residential strata or duplex development of small lots.
[029] Figure 10 depicts a further embodiment illustrating how the invention is adapted to groups of units, retirement homes or town houses using strata schemes.

[041] The following detailed description of the invention refers to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to like parts. Dimensions of certain parts shown in the drawings may have been modified and/or exaggerated for the purposes of clarity or illustration.
[042] The preferred embodiment of the invention refers to application to a new residential land subdivision. However the nature of sewerage systems is that they have many variations due to the different types of buildings serviced. Also the reader will appreciate this invention could be applied with the appropriate modifications to both new and existing developments. Equally it will be understood that adaptations can be made to the invention to suit commercial, non-residential construction and indeed multiple level units or town houses and the like.
[043] The present invention provides an improved remotely monitored and solar powered localised sewerage system for areas not connected to the mains reticulated sewer system. Said invention comprises apparatus to convey sewage waste underground from connection points on each one of a plurality of land lots to sewage treatment facilities on a separate parkland lot.
Examples
[044] Figure 1 is a small example as described above. The reader will gain a better appreciation of the benefits this novel invention layout provides from the following explanation. Firstly, there is no onsite sewage treatment on each residential lot 5 which immediately makes smaller lots possible and increases usable space for owners on each lot (Figure 3B). Further, all treatment facilities are located where there is vehicle access to enable servicing independently without involving lot owners. The major components of treatment unit 13 and reticulation field 2 are located in the separate parkland lot 1 which is of sufficient size to provide both environmental advantages and aesthetic landscaped park facilities for residents.
[045] Referring again to Figure 1, the house sewer on each lot 5 is connected 8 to a branch sewer line 10 a short distance within the boundary of each lot 5. Just outside the lot 5 boundary is installed a septic tank 9 to enable removal of solids and sludge 33 from effluent. Said effluent is expelled from said septic tank through a pumping tank 75 and conveyed by a solar powered pump with timer mechanism 77 to the parkland sewage treatment facilities 13._Said tanks 9, 75 are positioned between the lot 5 front boundary and the street to allow independent service access as required. A more detailed embodiment of the septic tank 9 is provided in Figure 4.
[046] The above embodiment would represent a typical situation where infill subdivision is proposed on a large lot 6 to create in this case twelve residential lots 5. From this, the reader will appreciate the invention may be adapted to comprise many different variations.
[047] Figure 2B shows application of the invention to a larger scale embodiment. When designing a large estate of lots it is preferred to connect lots 15 in small groups to sewage treatment facilities 17 each located on parkland lots. The result is beneficially, an estate with much fewer sewage treatment units than the individual onsite method, all of which are independently serviceable. The small parks thus created provide attractive green space to the community.
[048] Turning now to a more detailed embodiment on an individual lot in Figure 3B we see that the only space taken up by the invention is the connection pipe 29 from the dwelling to the front of the lot 21 which then connects to the septic tank 9 and remainder of the invention outside the lot boundary. From this it is clear to the reader there is no requirement for reticulation fields 24 or onsite septic tanks 26 and 27 as depicted in Figure 3A. Most of the lot depicted in Figure 3B remains available for owner uses such as outbuildings, pool, tree landscaping and the like.
[049] Further, Figure 3A provides a typical layout of current practise with reticulation fields 24 and septic tanks 26 and 27 and associated connecting pipes 28. No house extensions, outbuildings, pools, vehicles or trees can occupy these areas. Additionally, the reader will appreciate just how difficult and costly it is for the water authorities to set up inspection and monitoring controls to ensure such onsite systems are maintained regularly.
[050] Figure 4 depicts one example of the many variations of dual tank septic systems. The primary function is to remove solids and sludge 33 from the household sewage waste prior to the remaining effluent being pumped to the next stage of the sewerage system at 31. Advantageously now, the tank is located between the front of each lot and the street to facilitate servicing independently from the lot owners with access points 32 at ground level 36. The addition of solar panels with electrical backup to power the pump and timer is a cost-efficient improvement which can be included.
[051] Figure 5 depicts several examples of sewer pipe fittings to be used in the construction of the invention. The reader would appreciate all methods of such construction are governed by the rules and guidelines contained in the Sewerage Code of Australia. Beneficially, the invention makes all aspects of system planning, flow estimation and detail design more straight forward and accurate because in most cases the number of lots, sewage load and layout, as well as gradient and environmental demands will be known in advance with new subdivisions.
[052] Figure 6 provides two examples of inspection manholes to be used with the invention. The practical advantages of small sewerage systems servicing groups of lots as seen in this invention include ease of maintenance. Manholes can be positioned where most needed. The load carried in the system is far less than mains reticulated sewerage. The installation costs are also far less than mains sewerage because the smaller area covered by the invention uses flatter gradient, shallow excavation depths and smaller diameter pipes. Beneficially, the water authorities have control over maintenance of the whole system, unlike the present monitoring problems facing onsite treatment systems.
[053] In Figure 7 the full capabilities of the invention can be appreciated by its inherent adaptability. Development opportunities come in all shapes and sizes and it is often the case that a small town lot subdivision becomes possible following rezoning of an infill block of land between two existing roads. Here, figure 7 introduces a further embodiment, wherein the sewerage system connections 8 are installed at the rear of each lot 5 because every lot already has street frontage to the pre-existing roads 12. Advantageously now, this provides an opportunity to create a parkland lot 1 at the rear of the land lots 5, wherein not only all sewage treatment facilities 2 and 13 can be accommodated, but also access 4 for servicing said facilities is conveniently located.
[054] Figure 8 illustrates a further embodiment wherein the invention can be adapted for use in commercial developments. The reader will appreciate the cost savings gained from the relatively small length of sewerage pipe work required. Commercial shops requires ample car parking space 57, which advantageously in this case, can also provide service access to maintain sewage treatment facilities 59. Practical benefits also result from using the parkland lot 58 to not only serve sewage treatment requirements, but also to offer aesthetic opportunities such as a landscaped outlook from the shops and seating arrangements along the paved access paths 66. The improved layout afforded by the invention allows all commercial premises to receive delivery of supplies to the rear of each unit 63.
[055] Figure 9 illustrates an embodiment which satisfies the demand for small, easily maintained lots that have not been provided in many country towns for decades. The demand stems from many young people with full-time employment, who are time-poor; also retirees, who often search for homes with less garden work. People with disabilities also want these small lots. Cost saving is also a factor. Advantageously, the invention may be adapted to these smaller size lots through strata and duplex schemes. In Figure 9, the reader can appreciate how there remains ample space for sewage treatment facilities 13 and 2 on the parkland lot 1. Further, said parkland lot can easily become an attractive landscaped park for the community, whilst the economical sewerage system installation has low environmental impact. The septic tanks 9 and small quantity of pipe work 3 require shallow excavation compared to reticulated mains sewerage. Such a configuration has the advantage for the water authority of making servicing completely independent of lot owners. Billing for said servicing may be made through the strata scheme.
[056] Figure 10 depicts how the invention may be further adapted to suit groups of units, retirement homes or town houses. Here, through a strata scheme arrangement, combined septic tanks 72 are located underground in the parkland lot 1. This configuration comprises multiple units 67 with common boundary walls, garages 69 and courtyards 74 overlooking the central landscaped parkland. Servicing all treatment facilities is made simpler by locating all said facilities in said parkland.
Industrial Applicability
[057] Overall, the invention provides a completely novel method of combining sewerage apparatus with technological developments and discoveries in bacterial sewage treatment enabling land subdivisions of all sizes and small lots across Australia wherever it is not practical or cost-effective to consider infill mains reticulation sewerage.
[058] In particular, many country towns have not been able to consider subdivisions of smaller lots for many decades due to the high cost of infill sewerage. The invention offers a way for small and large land developers and town councils to meet this substantial demand. Therefore the invention has very large nationwide industrial applicability.
[059] In another aspect of industrial applicability, the reader should appreciate the sheer size of considerable expenditure savings, in the many millions of dollars, available to governments by implementing the invention as an alternative to mains reticulated infill sewerage.
[060] Industrial applicability also stems from a further advantageous example of large scale savings. By adopting the present invention, water authorities and appropriate governing bodies would have no additional onsite owner-controlled sewage treatment systems to monitor. The present invention may be remotely monitored and reliably serviced under full control of the water authorities. The cost of so doing may be billed directly to lot owners in a similar way to the present water and sewerage rates.
[061] Further advantages and improvements may be made to the present invention without deviating from its scope. Although the invention has been shown and described in what is conceived to be the most practical and preferred embodiments, it is recognized that variations and modifications may be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the appended claims so as to embrace any and all equivalent devices and apparatus. Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of the common general knowledge in this field.
