Drainage system for connection to an infiltration system
The present disclosure relates to a drainage system for connection to an infiltration system. The present disclosure also relates to a method for guiding water away from streets. Normally, infiltration systems and drainage systems are separately used. A drainage system may comprise a gully that is placed for instance in a street and collects rain water for very fast disposal down the drainage system in, for instance, a river, using gravity. Infiltration systems tend to be blockshaped structures, for instance, cubics, which are provided with a water permeable bottom, top and side walls that enclose together a cavity. The top, bottom and walls allow for penetration of water into the cavity. Water that ended up in the ground, i.e. water that was not collected by a gully and not transferred away via a drainage system, finds its way through the walls of the structure into the cavity from where it may over time slowly find its way out of the structure again through the walls and/or the bottom back into the ground. Infiltration systems are also referred to as attenuation systems.
There is a need for alternative systems.
Summary of the present disclosure
Provided is a drainage system for connecting to an infiltration system. The drainage system comprises at least one gutter element having at least one inlet, at least one outlet and a reservoir having a bottom. The drainage system is configured for having in use relative to the direction of gravity the at least one inlet at an upper part of the drainage system, the bottom at a lower part of the drainage system and the at least one outlet, for instance, between the bottom and the at least one inlet. Advantageously, the drainage system provides thus a buffer for rain water that enters the at least one inlet. Only when the water level in the reservoir has reached the level of the at least one outlet, water will leave the drainage system. In practice, the at least one outlet is directed toward or into an infiltration system. Preferably, the at least one inlet comprises a number of inlet openings and the at least one outlet comprises a number of outlet openings.
In an embodiment each of the outlet openings is smaller than the largest inlet opening. Advantageously, leaves which may have entered the inlet opening are unlikely to leave the outlet opening and may sink to the bottom of the reservoir, and wait to be cleaned away. Accordingly, such leaves will thus not block a passage for water into the infiltration system
In an embodiment the inlet openings are spatially separated from each other in a first pattern that resembles a line. Accordingly, such a drainage system can be put alongside an infiltration system. For instance, where the infiltration system is placed under a runway on an airport, the drainage system can be placed such that the inlet openings form a line along the runway.
In an embodiment pairs of the inlet openings are in the line at regular distances from other pairs of the inlet openings. Herewith, the weakness introduced by the openings can be balanced out by the strength of the parts of the system that do not entail an opening.
Preferably, each inlet opening has a maximum length of about 35 mm. Also preferably, each inlet opening has a maximum width of about 15 mm.
In an embodiment, each inlet opening has its length direction corresponding with the direction of the line, as referred to above.
In an embodiment, the outlet openings each have a maximum diameter that is smaller than the smallest dimension of each of the inlet openings. Accordingly, items of a certain size, such as leaves, may find their way into the drainage system via the inlet openings, but may be too large for finding their way out of the outlet openings. As such, the drainage system may filter the water and ensure that such leaves will not block passages for water into the infiltration system. The leaves will over time sink in the reservoir down to the bottom and wait to be cleaned away. Preferably, each outlet opening has a maximum diameter of 14 mm.
In an embodiment, the outlet openings are grouped in groups of outlet openings, wherein the groups are spatially separated from each other. This allows for connecting up with an infiltration system that has for instance columns. Ideally, the groups are positioned such that the outlet openings are directed to openings between the columns, instead of directed onto the columns. Preferably, the system is provided with at least one block-shaped protrusion and one of the groups of outlet openings is provided in a protruding surface of one of the block-shaped protrusions. This allows for directing water that leaves the drainage system to really be entering the infiltration system. Preferably, each of the at least one block-shaped protrusions is in use suitable for protruding between two columns of an infiltration system, as explained above. Preferably each of the block-shaped protrusions is provided with side connectors for adopting a connected condition in which the block-shaped protrusion is connected to the columns between which it is placed.
In an embodiment the at least one inlet opening faces water that follows the direction of gravity. This provides for a suitable way of collecting water in the drainage system. Preferably, each of the inlet openings is, relative to the direction of gravity, situated a little lower than its immediate surrounding, so that water tends to flow optimally into the inlet openings. Preferably, the at least one outlet opening extends parallel to the direction of gravity. The at least one outlet opening will be used to a larger extent when much more water is available for leaving the outlet opening. There is a certain threshold to overcome, preventing floating items, such as small leaves, from easily being flushed out of the outlet opening.
In an embodiment, the at least one outlet allows for more flow of water than the at least one inlet. Accordingly, it is unlikely that the drainage system will ever be fully filled up with water to an extent that water will again leave the drainage system via the at least one inlet opening, or not even enter the inlet openings.
In an embodiment, within the gutter element the bottom is concave for easy cleaning. Preferably, each gutter element is provided with a sleeve and a spigot for connecting to another gutter element. Accordingly, the drainage system can extend in a longitudinal direction following a line parallel to a lengthy path. Preferably, one of the gutter elements is provided with a possibility for connecting to an accessible gully, so that with a hose entering that gutter element from that gully at least a number of gutter elements can internally be cleaned.
In an embodiment, the bottom is on the outside provided with bottom-connectors for adopting a connected condition in which the bottom is connected to an infiltration unit onto which it is placed. Preferably, the bottom-connectors allow for placement of the bottom onto a bottom part of an infiltration unit and therewith establish a point of contact, and for then using the point of contact as a pivotal point for rotating the gutter element in a connected condition, optionally assisted by pushing the gutter element into a predetermined position of the infiltration unit.
Preferably, each of the at least one gutter element extends significantly more in the longitudinal direction as compared to a transverse direction, wherein the longitudinal direction and the transverse direction are each in an imaginary plane that is normal to the direction of gravity. Preferably, the at least one gutter elements are connectable to each other so that the reservoir extends in a longitudinal direction, and so that the drainage system extends in a longitudinal direction. For that purpose each gutter element may comprise a sleeve-end and a spigot-end.
The present disclosure is also directed to a method for guiding rainwater away from streets.
The present disclosure is further explained with reference to an exemplary drawing, in which:

An example of a drainage system according to the present disclosure is presented in the Figures. The block-shaped protrusion is not necessarily strictly having the shape of a block. An example of an infiltration system to which the drainage system may be connected is presented in WO 2016/042139, WO 2016/042140 and in WO 2016/042141. In this example no side walls are shown. For this example these are optional and often only in place at external sides of a cluster of the infiltration systems as shown. However, it should be clear that a drainage system according to the present disclosure may be adapted to fit any other infiltration system.
