Description

-1- A system for assembling a road as well as a method for capturing traffic-produced contamination, use of a system of filters for removing traffic contamination from water, and a plastic supporting structure for supporting a road and having a filter Thedisclosure relates to a system for assembling a road. The establishment of a road by assembling the road out of parts, wherein modules are available for lining-up and connecting to make the road, has the advantage that the footprint needed for putting down the road is relatively small. Also the speed by which such a road can be laid is very advantageous.
Overall, establishing such a road can be said to have a relatively low impact on the environment. WO 20207022888 A1 describes a system and a method for building such a road. Rainwater that falls onto the road is preferably collected, and somehow guided into a predetermined direction, which may be the direction of a drainage system. When much rainwater falls, a drainage system cannot always cope. The supply of rainwater may simply be too much. Ideally, the rainwater, then often referred to as stormwater, may find its way into underground infiltration systems for temporarily storing the water WO2016/042141 A1 describes an example of such systems. Over time, the water may from such systems slowly permeate into the ground. When such rainwater, or stormwater, finds its way into a system where it is temporarily stored before it isreleased into the sewage system, reference is made to attenuation systems. Such systems do not allow for permeation of water from the underground storage into the ground. As with any road, rubber particles that are worn off from the tyres of cycles, motorbikes, and larger vehicles, contaminate the road and its surrounding. When it comes to motorized traffic over the road there is a chance that also oils may be released onto the road and into its surrounding. Further, in the environment are nowadays always microplastic particles present. These are often captured by rainwater and end-up in the ground from where it is almost impossible to ever remove them. Such microplastics may ultimately end in water that flows down the rivers and into the seas. Unfortunately, the microplastics are likely to enter the food chain at some stage.
In view of the above, there is a need for addressing contaminations in rainwater that falls onto a road. However, land becomes more and more expansive. An extra footprint for capturing such contaminations is often considered too costly.
-2- The disclosure also relates to a method for capturing traffic produced contamination.
The disclosure further relates to use of a system of filters for removing contamination from rain water.
The disclosure relates also to a support structure for use in the system for assembling a road.
Summary of the disclosure The disclosure provides a system for assembling a road.
The system comprises a plurality of plastic support structures and a plurality of road deck elements.
Each of the support structures comprises a base plate and at least one supporting element that extends, or is for extending, upwardly from the base plate for supporting at least partly one of the road deck elements.
In an assembled condition, the system is such that when rainwater falls onto the road, it predominantly flows away over the road to one or more rainwater collection points adjacent each support structure and/or each road deck element.
The plurality of plastic support structures comprises a multi-functional support structure which is provided with at least one filter for filtering rainwater that has from the one or more rainwater collection points entered a treatment volume which is spanned by dimensions of the multi-functional support structure.
At least a part of the at least one filter is positioned within that treatment volume.
Advantageously, facilitating removing contamination from rainwater can accordingly take place within space that is already taken up by infrastructure needed for a road.
As the multifunctional support structure is a one of the plurality of support structures which are present anyway for supporting the road deck elements of the road deck, there is hardly a need, if at all, for enlarging the footprint and/or the volume of the road.
Preferably the treatment volume is in its entirety within the dimensions of the multifunctional support structure, so that no extra footprint and no extra volume is required for having this facility for removing contamination from rainwater that falls onto the road.
According to an embodiment, in the assembled condition the system is such that rainwater which is collected by the one or more rainwater collection points and that has entered the treatment volume, includes rainwater which has flowed over at least an other area of road deck.
The other area of road deck is different from an area of road deck that covers that at least one multifunctional plastic support structure.
Advantageously, for filtering all the rainwater that falls down on the road only one out of a plurality of plastic support structures needs to be provided with the at least one filter, making it not only economically viable for making the system, but also economically viable
-3- for maintaining the road in that only a relatively small number of the supporting structures will over time need to be assessed for cleaning or replacing the at least one filter, partly or in its entirety.
According to an embodiment of the system, in its assembled condition the system is such that rainwater which has been filtered by the at least one filter finds its way away from the treatment volume into other volume. Advantageously, there is no need to actively remove the filtered water.
Further, the at least one filter can continuously be in use without a need for consumption of mankind-made energy sources.
In an embodiment, that other volume is covered by the other area of road deck. Thus, the filtered water may at least temporarily be kept under the road. Preferably, the other area of road deck is area of road deck under which no such multifunctional plastic support structure is present. Ideally, the other area of road deck is area of road deck under which an infiltration system is present for temporarily storing water before it permeates into the ground. Such systems are known systems and assist for instance in the handling of stormwater. When much rain falls in a short period of time and the drainage systems cannot cope with the amount of rainwater, much of that water may quickly find its way into such systems. The system of the present disclosure allows for assembling a road and filtering out of rainwater that flowed over that road the contamination before that rainwater ultimately permeates into the ground. Preferably, a path for rainwater into such infiltration systems is predominantly, if not exclusively, available via the treatment volume, and even more preferably, via the at least one filter.
Although it is envisaged that the other area of road deck is area of road deck under which an infiltration system is present for temporarily storing water before it permeates into the ground, it is also possible that instead of an infiltration system, and attenuation system is present under that other area of road deck. It is even conceivable that under a part of that other area of road deck an infiltration system is present and that under another part of that road deck an attenuation system is present.
Astherainwater is filtered before it finally enters the infiltration from where it over time permeates into the ground or is released into the sewage system, there is also no need to expect that infiltration systems over time slip full with small particles that undermine the capacity and the response time of the infiltration units, in case stormwater needs to be managed, and/or, when the water should permeate from the underground infiltration systems into the ground.
4 - Also for attenuation systems there is a need to avoid that contamination collects in the underground system and a need to avoid that from there the contamination find its way into rivers and the seas. Ideally, the contamination does not enter the attenuation system in the first place.
A system according to the disclosure, is expected to have a long life-time in use, with low maintenance requirements, and improved prospects for the environment. The disclosure also provides for a method for capturing contamination out of rainwater that has flowed over a road deck, comprising: - collecting rainwater that has flowed over a road deck to one or more rainwater collection points adjacent the road deck; - allowing the collected rainwater to flow into a treatment volume; - allowing floating dirt in the treatment volume to be separated from the rainwater; - allowing the rainwater in a part of that treatment volume to flow through a relatively coarse filter; - allowing the rainwater downstream of that coarse filter to flow through a relatively fine filter that is configured to capture at least one of Petroleum Hydrocarbons (TPH), Fats, Oils and Grease (FOG), oily sheen, microplastic particles and small rubber particles; - allowing the rainwater downstream of that relatively fine filter to move away from the treatment volume. Preferably, the treatment volume is underneath the road. In an embodiment, the collected rainwater is collected from parts of the road which are free from having underneath the road the treatment volume. Preferably, the parts of the road that are free from having underneath the road the treatment volume, have underneath the road an infiltration system for temporarily storing rainwater before it permeates into the ground, or have underneath an attenuation system for temporarily storing rainwater before it finds its way further into sewage system. Rainwater downstream of that relatively fine filter preferably moves thus an infiltration system or into an attenuation system. The disclosure further provides use of a system of filters for removing contamination from water, wherein the use is preferably in a system for assembling a road.
-5. The disclosure also provides a support structure made of plastic and comprising a base plate and at least one supporting element, extending, or for extending, upwardly from the base plate for supporting at least partly a road deck element in a system for assembling a road.
The support structure is provided with at least one filter for filtering rainwater that has entered a treatment volume, wherein the treatment volume is spanned by dimensions of the support structure, wherein at least a part of the at least one filter is oriented parallel to the surface of the water or includes an acute angle with the surface of the water, and/or wherein at least a part of the at least one filter is configured to adsorb and capture at least one of Petroleum Hydrocarbons (TPH), Fats, Oils and Grease (FOG), oily sheen, microplastic particles and small rubber particles, the at least one filter being positioned around and/or between the at least one supporting element, so that the support structure itself is unchanged by the presence or absence of the at least one filter.

Detailed description of the disclosure with references to the drawing Figure 1 shows a part of a road 1 that can be made with a system according to the present disclosure. Fig. 1 shows an embodiment of the system once it has been put in an assembled condition. In this example, two road deck elements 2 which are almost square-shaped, are on either side of a smaller two-part road deck element 3. The almost square-shape road deck elements 2 each cover, and are supported by, two plastic support structures 4, which are partly visible in fig. 2 and much better visible in Fig 14. The smaller road deck element 3, having two parts 3a and 3b, covers, and is supported by, a plastic support structure 4 that is in fact a multifunctional support structure 8. Further below, it will become clear to the reader why the term “multi-functional” is selected for referring to that structure. The arrows A show the direction of the road, also referred to as the road direction, or even the direction of traffic over the road.
In Fig. 2 is more clearly visible that each support structure 4 comprises a base plate 5 and at least one supporting element 6, extending upwardly from the base plate 5 for supporting at least partly one of the road deck elements 2. The at least one supporting element 6 is in the embodiment shown an integral structural feature of the structure 4. That is, the supporting element 6 and the base plate 4 form each a structural feature of a one-piece structure 4. In other words, in the embodiment
-7- shown throughout this disclosure, the supporting element and the baseplate are seamlessly connected with each other. In an alternative embodiment (not shown), the supporting element 6 is a separate element that is connectable to the base plate 5. That supporting element is thus for extending upwardly from base plate 5, for supporting at least partly one of the road deck elements
2. Reference is further made to WO2020/022888 A1, which also describes supporting structures, suitable for supporting at least partly a road deck element. In an assembled condition, the system is such that when rainwater falls onto the road 1, it predominantly flows away over the road 1 to one or more rainwater collection points CP. In this disclosure, the phrasing "flows over the road” is to be understood as contrasting to “flowing into the road or through the road”. The phrasing "predominantly flows over the road” is understood to mean that more than, say 90%, of the water flows over the road, as opposed to flowing into or through the road. Ideally more than 95%, and even more preferably more than 99% flows over the road. Flowing into or through the road would for instance be possible if the road deck would be water permeable or for instance when the road deck is provided with many perforations. The water collection points are adjacent each support structure 4 and/or each road deck element 2, 3a, 3b. The actual position of the water collection points, can be next to the road, a little under the road, for instance at a side of the road, next to the support structure, etc. and is thus not critical provided that it is adjacent enough and so that water that has flowed over the road can be collected at the rainwater collection points. An example of the flow direction of water is schematically presented in Fig. 2 by a line having multiple arrows, referred to as WF. An embodiment of the system comprises a plurality of inlet- gutter parts 7, so that in an assembled condition of the system adjacent each support structure 4 and/or each road deck element 2, 3a, 3b at least a part of an inlet gutter 7 extends for functioning as multiple rainwater collection points CP. In an assembled condition of the system the inlet gutter 7 streamlines in a traffic direction A of the road 1 a flow of rainwater of which at least a large amount of rainwater has flowed over the road deck of the road. However, it is pointed out that the inlet-gutter can be extending into any other direction, such as for instance, somewhat transvers to the road direction, and does also not need to extend into a straight line. The plurality of plastic support structures 4 comprises a multi-functional support structure 8 which is provided with at least one filter 9 for filtering rainwater that has from the one or more rainwater
-8- collection points CP entered a treatment volume TV which is spanned by dimensions of the multi- functional support structure 8. The treatment volume fits thus, at least partly, within a geometrically determined volume that is defined by connecting the most outer positions of the supporting structure. At least a part of the at least one filter 9 is positioned within that treatment volume TV. Going back to Fig. 1, in the assembled condition an embodiment of the system is such that rainwater which is collected by the one or more rainwater collection points 7 and that enters the treatment volume TV, includes rainwater which has flowed over at least an other area of road deck, wherein the other area of road deck (ORD) is different from an area of road deck (RD} that covers that at least one multifunctional plastic support structure 8. This is in Fig. 1 schematically shown by the dashed line visible under the road deck elements 2, 3a, 3b. That dashed line enters a volume under road deck element 3a. On the top of the road deck elements 2, 3a, 3b also dashed lines and dashed arrows are shown, schematically indicating that in an assembled condition the system is such that rainwater which has been filtered by the at least one filter, finds its way away from the treatment volume TV into other volume. Preferably, that other volume is covered by the other area of road deck 2, so that it is not again contaminated by contaminants, for instance contaminants which are produced by traffic that moves over the road. Preferably, the other area of road deck 2 is area of road deck 2 under which no such multifunctional plastic support structure 8 is present. Although, not necessarily the case for all systems according to the disclosure, the other area of road deck is area of road deck 2 under which an infiltration system is present for temporarily storing water before it permeates into the ground. The system of the embodiment shown comprises a plurality of inlet-gutter parts 7, so that in an assembled condition of the system adjacent each support structure 4, 8 and/or each road deck element 2, 3a, 3b at least a part of an inlet gutter 7 is provided, extending in the direction A of the road for functioning as multiple rainwater collection points CP. The inlet gutter parts 7, shown in Fig. 15 and 16, are generally U-shaped and connectable, given spigots and sockets that allow for a swift connecting during assembling and then allow for a watertight connection. In an assembled condition of the system, the inlet gutter 7 streamlines in a traffic direction A of the road a flow of rainwater of which at least some rainwater has flowed over the other area of road deck 2 (ORD). In an assembled condition of the system the inlet gutter 7 also collects rainwater that has flowed over the area of road deck 3a, 3b (RD) that covers one of the multi-functional plastic support structures
8. Not only figure 1 but also Fig 12 displays this schematically by means of arrows. In the assembled
-9- condition of the system rainwater flows into the treatment volume TV when the rainwater has reached a predetermined height in the inlet gutter 7. The part of the inlet gutter 7 that is adjacent the multifunctional plastic support structure 8 and/or road deck 3a is provided with flow exits 10 for releasing rainwater into the treatment volume TV. Fig 16 shows such a part of the inlet gutter
7. Fig 4 to Fig 12 show various views of the multifunctional plastic support structure 8. From comparing Fig 4 and 5, it is clear that in the assembled condition of the system, the treatment volume TV is in its entirety under area of road deck 3a, 3b that covers that at least one multi- functional support structure 8. In Fig. 5, 8, 11 and 19, is visible that multi-functional plastic support structure 8 may be provided with upwardly standing side plates 18. These can for instance placed and held in fixed position by a connection at multiple positions with the multifunctional support structure 8. These side plates provide support for an impermeable foil that may be placed at an outer side of the multi-functional support structure, i.e. underneath the base plate 5, and outside the side plate 18 and for instance between the inlet-gutter 7 (and outlet gutter 12) and the multi- functional support structure 8 for providing a physically delimited treatment volume TV. The at least one filter 9 comprises upstream a coarse filter 9a for filtering particles out of the water based on a mesh size of the filter. As shown in Fig 4, 5, 6, 7, 10, and 12, in an assembled condition of an embodiment of the system, at least a part of the coarse filter 9a is oriented parallel to the surface of the water. However, there may additionally, or alternatively, be at least a part that includes an acute angle with the surface of the water. The treatment volume TV is upstream the coarse filter arranged to let rainwater pass a position that is below the coarse filter 9a. The at least one filter 9 comprises downstream of the coarse filter 9a a relatively fine filter 9b that is configured to capture at least one of Petroleum Hydrocarbons (TPH), Fats, Oils and Grease (FOG), oily sheen, microplastic particles and small rubber particles. The at least one filter may also comprise a floating dirt separator for separating floating dirt from the rainwater that flows through and thus out of the at least one filter. An oil separator OS, may be an example of such a floating dirt separator. The floating dirt separator may be positioned at the most upstream part of the at least one filter 9. The term “filter” thus also embraces the concept of a separator.
-10- The treatment volume TV includes at least one part for facilitating sedimentation. The at least one part for facilitating sedimentation comprises a first part S1 for facilitating sedimentation upstream the at least one filter. The at least one part for facilitating sedimentation comprises a second part S2 for facilitating sedimentation upstream the relatively fine filter. The treatment volume is in this example defined by impermeable material shaped for holding a volume of water that is at most equal to the treatment volume. The impermeable material could be a foil, f.i. bag-shaped or container-shaped into which the multi-functional support structure is positioned. The treatment volume TV is provided with an overflow-exit which regulates that the treatment volume at most holds a volume of water that is equal to the treatment volume TV. Preferably, in an assembled condition of the system, the system comprises at least one overflow-exit, preferably under the road deck. An overflow-exit is not necessarily a dedicated hole in an element of the system, it may equally by limited height of a part that physically delimits the treatment volume TV. Figure 19 and 20 indicate where in an embodiment of the system in the assembled condition the functioning of an overflow-exit may be facilitated. The same applies for a pathway for aeration.
The embodiment of the system as shown also comprises a plurality of outlet gutter-parts 12, so that in an assembled condition of the system adjacent each support structure 4, 8 and/or each road deck element 2, 3a, 3b at least a part of an outlet-gutter 12 extends in the direction of the road, for streamlining in a direction of the road a flow of rainwater that has been filtered by the at least one filter 9. Also for the outlet gutter 12 it applies that these may additionally, or alternatively, at least partly extend in a direction that is transverse to the road direction. In the embodiment shown, the relatively fine filter 9b comprises a number of walls which are water permeable. A downstream side of the walls has a fluid communication with the outlet gutter 12. Preferably, the walls have at least partly the shape of pipes 11 of which an upstream end is closed by a part 11a of the walls and of which a downstream end 11b streamlines a flow of filtered rainwater into the outlet gutter 7. However, although not shown, the downstream end 11b may also streamline filtered water directly into volumes that neighbour the treatment volume and that is under the other area of road deck (ORD). The pipes 11 may each have annular ribs and infiltration holes therein between. A geotextile sheet may be wrapped around each of such the pipes 11. Such pipes are known as IT -pipes. The longitudinal direction of the pipes 11 are preferably across the traffic direction of the road. This ensures that treatment volume TV and the multi-functional support structure 8 only need to occupy
-11- over a short stretch of the volume under the road in the road direction. Further, only over a short stretch of the road needs the road to be open when cleaning and/or replacing of filters, parts for sedimentation etc are needed.
In the assembled condition of the embodiment shown, rainwater that has been filtered by the at least one filter enters via the outlet gutter volume under the other area of road deck (ORD). In the assembled condition of the system, in the outlet gutter parts 12 adjacent the plastic support structures 4 which are different from the multi-functional support structure 8, at least one flow exit 13 is provided as shown in Fig. 17 for releasing filtered rainwater into the volume under the other area of road deck (ORD). Figure 18 shows an outlet-gutter part 12 for placement next to the multi- functional support structure 8. Prefabricated closed recesses 16 for connecting pipes 12 are already provided. The recesses 16 can easily be opened by removing the material that closes the recess off. The recesses in Fig. 18 are shown to be opened.
As can be seen from Fig. 15-18, the inlet-gutter parts and the outlet-gutter parts can be identical. The flow exits 10 and 13 can also be identical. This allows for an economically viable way of making the inlet- and outlet-gutter parts.
Under the other area of road deck (ORD) an attenuation system is present for temporarily storing water before it permeates into the ground. Reference is made to WO 20207022888 Al for a road that is also made using attenuation systems, and to WO2016/042141 Al for an example of an attenuation system.
The road deck 3a,3b that covers one of the multi-functional plastic support structures 8, has a first part 14a and a second part 14b, wherein the first part 14a, can be lifted independently of the second part 14b, and wherein the first part extends at most up to a part of the width of the road. Advantageously, a part of the width of the road can still be used when the required maintenance and cleaning activities are carried out. Lifting the first part will also facilitate access to inlet-gutter 7 for cleaning that gutter.
Each of the plastic support structures of the plurality of plastic support structures is in structure the same, and preferably also in dimensions the same. This enables an economically viable way of producing the system. Preferably each of the structural features that has been added to a support structure to change it functionally into a multifunctional support structure, is mechanically
-12- connectable to that structure or placeable onto that structure. Preferably, the support structure itself, in terms of the base plate 5 and the supporting elements 6, is unchanged by the presence or absence of the at least one filter.
In an assembled condition of the system, one plastic support structure out of at least five, preferably out of at least 10, and even more preferably out of at least 15 of out of the plurality of support structures corresponds to one of the multi-functional plastic support structures. It is not inconceivable that only one out of twenty, thirty or even forty support structures needs to be a multifunctional support structure to obtain a road that allows for filtering the rainwater out of the water that flows over the road. A dimension of a road deck element 2 is in traffic direction of the road 1 preferably able to span in an assembled condition of the road 1 at least two plastic support structures 4. The road deck elements 2, 3a, 3b are preferably shaped such that in an assembled condition of the system the road slightly slopes off towards one side of the road, by a slope of the road deck elements. Each road deck element may then have a most upper road deck that in the assembled condition of the system slightly slopes off (1-3%) in one direction across a traffic direction of the road. Accordingly, the water would always flow towards the side at which the inlet gutter is positioned. However, often this sloping of the road may be achieved by simply ensuring that the ground of the bedding has slope that is between 1 and 3 % degrees, so that the system does not need to facilitate for achieving a slight slope. In the assembled condition of the system, the flow exits 10 in the inlet gutter parts 7 for releasing rainwater into the treatment volume TV facilitate the generation of a flow when a first height of water in the inlet gutter 7 is reached, and the flow exits 13 in the outlet gutter parts 12 for releasing rainwater into volume under road deck elements 2 facilitate the generation of an flow when a second height of water in the outlet gutter 12 is reached. The first and the second height may be the same, enabling a simplification of the production of the gutter parts, the logistics and storage thereof, etc. The gutters 7 and 8 are, as can be seen from figures 15-18 very similar, if not identical, apart from the presence of flow exits 10, 13. The gutter part 7, 12 are preferably provided with integral connectors 20 at positions shown in Fig. 15-18 for connecting to for instance a supporting element 6 (upper connector 20) and the base plate 5 (lower connector 20). The supporting elements 6 and the base plate 5 ideally has
-13- corresponding integral connecting points. The type of mechanical connections that are suitable can easily be chosen by a person skilled in the art. For instance, a snap-fit connection that is firm, requires no extra tools, and allows for disconnecting in a non-destructive fashion, may be ideal. As is also seen, the gutter parts 7,12 are preferably each incorporated in stabilizing part 19, that provides for a stable positioning of the respective gutter part, as it not only allows for connecting to the support structure, but also for resting on the ground.
Figure 21 and 22 show schematically, the level of the water, relative to the parts of an embodiment of the system when the base-plate 5 is put under a small angle with the horizontal level. Fig. 21 shows the multifunctional support structure 8 and Fig. 22 shows the support structure 4. If the respective flow exits 10, 13 are indeed at the same heights in the inlet gutter 7 and in the outlet gutter 12, than this positioning facilitates in a relatively slow movement of the water through the system, facilitating even more the sedimentation and/or the filtering.
Preferably, an embodiment of a system according to this disclosure is provided with at least one sensor for detecting the status of the at least one filter, wherein status includes one of filter sensitivity, filter capacity, and pressure exerted onto the filter.
The road decks 2, 3a, 3b are connectable to each other, preferably using a spacer for fixation to a construction element (in this case a road deck), for maintaining a relative distance to another construction element (road deck), and for restricting a movement about a position relative to another construction element (road deck), such as disclosed in WO 2019/170630. ideally, a gap between the road decks is occupied by rubber strip 17 as for instance shown by Fig 23.
The embodiments shown are examples of a system that allows for carrying out a method for capturing contamination out of rainwater that has flowed over a road deck, comprising: - collecting rainwater that has flowed over a road deck to one or more rainwater collection points adjacent the road deck; - allowing the collected rainwater to flow into a treatment volume; 36 - allowing floating dirt in the treatment volume to be separated from the rainwater; - allowing the rainwater in a part of that treatment volume to flow through a relatively coarse filter;
-14 - - allowing the rainwater downstream of that coarse filter to flow through a relatively fine filter that is configured to capture at least one of Petroleum Hydrocarbons (TPH), Fats, Oils and Grease (FOG), oily sheen, microplastic particles and small rubber particles; - allowing the rainwater downstream of that relatively fine filter to move away from the treatment volume, The treatment volume TV may be underneath the road. The collected rainwater may be collected from parts of the road which are free from having underneath the road the treatment volume. Preferably, the parts that are free from having underneath the road the treatment volume, have underneath the road an infiltration system for temporarily storing rainwater before it permeates into the ground. Preferably, rainwater downstream of that relatively fine filter moves into the infiltration systems. Instead of infiltration systems, attenuation systems may be employed, in which water is temporarily sored before it finds its way into a sewage system.
Any known system for treating, and preferably filtering, water so as to remove contamination, may be employed. Such system may each be scaled up or down for removing contamination from water, and for placement under a part of a road.
The multi-functional support 8 structure ideally comprises the same base plate 5 and the same supporting elements 6 as comprised by the other supporting structures 4. The multi-functional support structure 8 also holds filters 9 in addition to supporting at least a part of the road deck. The term “multi-functional” as used throughout this disclosure is not be construed in a sense that the other support structures 4 would not carry out functions that differ from supporting at least a part ofa road deck.
The disclosure is not limited to the examples shown and discussed. Many variations and modifications are feasible. Each of these modifications and variations is within reach of a skilled person, once the present disclosure has been understood.
For instance, the supporting elements are shown as cone-shaped columns, but these may have any shape, including cylindrical, rectangular, block-shaped, extending not only upwardly but also laterally.
-15- The term road includes a very small road, more like a drive, and includes a road having a “dead- end”.
Instead of pipes 12 for the fine filter, any other shape is feasible for the wall that forms part of the fine filter. The walls may itself have many structural features, such as for instance circumferentially extending ribs, and may have many “perforations” or may be open by porosity to enhance the filtering sensitivity. In addition to the more rigid walls, or as an alternative to such rigid walls, also very flexible wall may be employed, including those made of cloth, textile, woven or non-woven fiber-based filter material etc.
The direction of collected rainwater flow can be chosen as is desirable and suitable for the positioning of the road. The path from rainwater to infiltration/attenuation system can be made so that it has much length and allows for sedimentation.
itis also possible to apply the present disclosure such that volume under the road divided up in two volumes that extend parallel to each other in road direction. One of the volumes may be used as the treatment volume, i.e. for removing contamination, and the other volume may be used for infiltration/attenuation purposes of the de-contaminated water. Such systems may be useful where the road itself is in road direction going slightly upwards or downwards. The possible variations and modifications within the framework of the appended claims are endless.
