[0001] The present invention relates to a heavy rainwater management system, which is adapted to the fluid communication between a heavy rainwater source and a well means.

Background Art

[0002] CN111592191A discloses a treatment and recycling system based on the quality of rainwater for low environmental impact development. This system includes a low environmental impact development system, a collection and treatment system based on the quality of rainwater, a rainwater recycling system, and a central control system. The central control system is connected to the low environmental impact development system, the collection and treatment system based on the quality of rainwater, and the rainwater recycling system. The collection and treatment system based on the quality of rainwater is connected to the low environmental impact development system. Both the low environmental impact development system and the collection and treatment system based on the quality of rainwater are connected to the rainwater recycling system. Although general rainwater treatment methods are described in this prior art document, details of methods for handling rainwater in the form of heavy rainwater are not disclosed. For example, CN111592191A does not disclose specific technical teachings for enabling a large amount of heavy rainwater to be reused in an urban environment. In particular, it does not explain how to handle the quantity and quality of rainwater that vary seasonally and how to control it by the treatment system and the well means.

Summary of the Invention

[0003] An object of the present invention is to overcome the drawbacks of the prior art as described above.

[0004] According to the present invention, this object is achieved by a heavy rainwater management system adapted to the fluid communication between the heavy rainwater source and the well means as described in claim 1.

[0005] The rainwater management system according to the present invention is adapted for fluid communication between at least one, preferably only one, rainwater source and at least one well means. Advantageously, the system may also include a rainwater storage tank, as further described below.

[0006] A heavy rainfall water source is any appropriate type. In particular, a heavy rainfall water source is rainwater sewage, which is supplied by rainwater from drainage systems within the urban environment, especially drainage pipes and drainage ditches.

[0007] The well means can be any suitable type. In particular, the well means is an aquifer storage unit that is at least partially supplied by water discharged from the heavy rain management system according to the present invention. For this purpose, the well means may include infiltration and intake wells that are in fluid communication with the aquifer storage unit. The water in the well means can be used in any suitable way. In particular, at least a portion of the water in the well means can be recycled to the heavy rain management system according to the present invention. It should be noted that the well means can be configured in many variations. For example, the well means may be a single well that can perform both infiltration and outflow, or the infiltration and outflow functions may be arranged in a configuration in which they are separated.

[0008] The filtration means according to the present invention comprises the following different components, namely, - At least one rainwater inlet, - At least one inflow sump, - Biological filtration means, and - At least one spill sump It has.

[0009] More specifically, the filtration means has at least one stormwater inlet means adapted to receive stormwater from a stormwater source. The stormwater inlet means is of any suitable type. In particular, this means is a pipe or duct that is in fluid communication with the stormwater source. It is conceivable to have at least one pump that pumps stormwater from the stormwater source to the inlet sump means through the tube and / or through the stormwater inlet means. However, it is preferable to provide the connection from the stormwater source to the stormwater inlet means by duct or tube to allow for gravity-driven fluid flow.

[0010] At least one inflow sump means is adapted to receive the stormwater from the stormwater inlet means, physically and / or chemically treat the stormwater, and discharge the treated stormwater downstream of the stormwater inlet means as inflow sump water. In other words, once the stormwater enters the inflow sump means, it is physically and / or chemically treated and flows out of the inflow sump means as inflow sump water. The inflow sump means is of any suitable type. In particular, the inflow sump means may include one or more compartments that are separated from each other but fluid-connected, each designed and adapted to store stormwater for a desired period or residence time. The period is adapted to allow particles in the stormwater to settle within at least one compartment. However, alternatively, it is possible to provide a corresponding inflow sump means having one or more compartments that are separated from each other but fluid-connected, each designed and adapted to store stormwater independently of a desired period or residence time.

[0011] The biofiltration means is adapted to receive at least a portion, preferably all, of the influent sump water from the influent sump means, adjust the saturation zone, physically and / or chemically treat the influent sump water, and discharge the treated influent sump water downstream of the influent sump means as biofiltered water. In other words, once the influent sump water enters the biofiltration means, it is physically and / or chemically treated and exits the biofiltration means as biofiltered water. The biofiltration means is of any suitable type. In particular, the biofiltration means has a base element, in particular a base plate, which may consist of concrete and / or geotextile or any other suitable waterproofing material. Alternatively, the biofiltration means includes a waterproofing structure consisting of edge elements that hold geotextile or any other suitable waterproofing material, which are held in place on the base plate. The edge elements and / or the base plate are preferably made of concrete. At least one layer of filter material, in particular sand, is placed on one of the base plates. Plants can be planted in at least a portion of the sand. The filter material and plants receive the inflow sump water filtered by the filter material and plants, at least partially. The biofiltration system may include multiple compartments having different or the same filter material and / or plants. The biofiltration system is adapted to regulate the residence time and permeability coefficient of the biofiltered water. The system is adapted to provide its mechanical screening and to promote the biodegradation of organic components and nutrients therein. Furthermore, the system is adapted to provide contact time with the plants provided in the biofiltration system, creating periodic redox conditions. Finally, the biofiltration system is adapted to regulate soil moisture control and saturation.

[0012] At least one outflow sump means is adapted to receive at least a portion of the biofiltered water from the biofiltration means and discharge the biofiltered water as outflow sump water downstream of the outflow sump means to a well means. The outflow sump means can optionally be adapted to physically and / or chemically treat the biofiltered water. In the latter case, the biofiltered water, upon entering the outflow sump means, is physically and / or chemically treated and exits the outflow sump means toward the well means as outflow sump water. The outflow sump means is of any suitable type. In particular, the outflow sump means may include one or more compartments that are separated from each other but fluidly interconnected, designed and adapted to receive the biofiltered water and regulate a continuous submerged zone within the outflow sump means. Furthermore, this means can be adapted to control the water level within the biofiltration means.

[0013] As can be understood from the above, the rainwater is treated physically and / or chemically multiple times before entering the well. This, in an advantageous manner, ensures that high-quality water based on the rainwater enters the well.

[0014] According to the present invention, the inlet sump and outlet sump are located within the same structure. The structure is of any suitable type. In particular, the structure is a building, housing, or container in which both the inlet and outlet sump are housed. This minimizes the space required for the filtration means according to the present invention, in an advantageous embodiment.

[0015] This also applies when at least one sensor means, at least one control means and / or at least one communication means are located within the same structure, which may be of any suitable type. In particular, the structure is a building, housing or container. In a particularly advantageous embodiment, the structure is the same structure that houses the inflow sump means and / or outflow sump means. This minimizes the space required for the filtration means according to the present invention and further simplifies maintenance of the stormwater management system in particular.

[0016] According to the present invention, the heavy rain water management system has at least one sensor means adapted to sense at least physical and / or chemical properties of heavy rain water, inflow sump water, biofiltered water, outflow sump water, heavy rain water inlet means, inflow sump means, biofilter means, and / or outflow sump means and / or therein. In particular, the sensor means is adapted to sense data representing values ​​particularly of electrical conductivity, pH, dissolved oxygen, dissolved organic carbon, nitrates, oil content, turbidity, light transmittance, water level, aeration, and / or algae.

[0017] Alternatively or additionally, the torrential rain management system according to the present invention has at least one control means adapted to control at least the physical and / or chemical properties of the torrential rain, inflow sump water, biofiltered water, outflow sump water, torrential rain inlet means, inflow sump means, biofiltration means, and / or outflow sump means and / or in them. In particular, the control means is adapted to control the residence time of water in the inflow sump means, biofiltration means, and / or outflow sump means. Alternatively or additionally, the control means is adapted to adjust the amount of biofilter supply to the biofiltration means, adjust the contact time between the biofiltered water and the root zone for plant absorption, and / or create periodic redox conditions therein. Furthermore, the control means can be adapted to operate in a time-dependent manner, and / or based on water volume conditions, and / or actual weather conditions and / or predicted weather conditions, and / or seasonal conditions. Alternatively or additionally, the control means are adapted to shut off the flow of relevant fluids within the rainwater management system according to the present invention and / or activate one or more bypasses when contaminants are detected, particularly based on data sensed by the sensors disclosed above, and / or activate any water pumps based on data representing the water quality conditions inside and / or outside the rainwater management system according to the present invention.

[0018] Alternatively or additionally, the stormwater management system according to the present invention has at least one communication means for receiving and / or transmitting data representing at least physical and / or chemical properties of the stormwater, inflow sump water, biofiltered water, outflow sump water, stormwater inlet means, inflow sump means, biofilter means, and / or outflow stormwater means and / or therein. In particular, the communication means is an electronic communication means, in particular an telecommunications means, which is adapted to transmit and / or receive the data disclosed above. For example, any value sensed by any of the sensor means disclosed above may be transmitted and / or received via the telecommunications means to and from an external or internal computer data bank system, a computer cloud-based storage system, or a computer-based computing system of the stormwater management system according to the present invention.

[0019] As can be understood from the above, the stormwater, inflow sump water, biofiltered water, outflow sump water, stormwater inlet means, inflow sump means, biofilter means, and / or outflow sump means are monitored continuously as needed. If the sensed physical and / or chemical properties of the aforementioned items, in particular the corresponding measured values, deviate from the target values, the control means intervenes in the stormwater inlet means, inflow sump means, biofilter means, and / or outflow sump means to adapt them until the sensed physical and / or chemical properties of the aforementioned items essentially correspond to the desired target values. Communication means make it possible to transmit and / or receive and / or exchange data representing the aforementioned measured values ​​and / or target values ​​inside and / or outside the stormwater management system, for example, with the control room. As a result, in an advantageous embodiment, all sensed physical and / or chemical properties of the stormwater, inflow sump water, biofiltered water, outflow sump water, stormwater inlet means, inflow sump means, biofilter means, and / or outflow sump means become transparent and can be further processed and transmitted to any relevant parties or technical means. It goes without saying that each value or data can be stored in volatile or non-volatile storage means, respectively.

[0020] It should be noted that any of the sensor means, control means, and / or communication means can be located in the inlet sump means and / or outlet sump means. Furthermore, the inlet sump means and / or outlet sump means are adapted to provide a sewer bypass for contaminated water. This prevents the contaminated water from entering the water in the well means.

[0021] In an advantageous embodiment of the present invention, at least one particle settling means and / or particle removal means is located in the inlet sump means and / or outlet sump means. This allows for further improvement of the water quality within the heavy rainwater management system.

[0022] This also applies when at least one saturation zone control means is provided, adapted to adjust for different saturation levels.

[0023] This is further true, according to an advantageous embodiment of the present invention, when the particle settling means and / or particle removal means each have at least one channel adapted to facilitate the washing of water inside the inlet sump and / or outlet sump. Optionally, at least one recessed channel and / or at least one mesh adapted to receive particles from the water inside the inlet sump and / or outlet sump, respectively. Alternatively or additionally, the particle settling means and / or particle removal means each have at least one screen.

[0024] In a more advantageous embodiment, the particle settling means and / or particle removal means comprises at least one washing means adapted to remove particles from the particle settling means and / or particle removal means. In an advantageous embodiment, the washing means is a drain to a heavy rain source, particularly to a heavy rain sewer. This allows for maintenance of the heavy rain management system as needed.

[0025] As disclosed above, the inlet sump and outlet sump are located within the same structure. According to an advantageous embodiment, the biological filtration means may also be part of the structure.

[0026] In a further advantageous embodiment of the stormwater management system, the influent sampling means and the effluent sampling means can be located adjacent to each other on the same side of the biofiltration means, but can be spaced apart from each other with respect to the axis of the biofiltration means, particularly the vertical or horizontal axis. The influent sampling means and the effluent sampling means can be located within a structure provided with said space therebetween. The structure can be of any suitable type. In particular, the structure is a building, a housing, or a container, in which both the influent sampling means and the effluent sampling means are accommodated, as well as the space therebetween. This space is adapted to receive at least one sensor means, one control means, one communication means, one means enabling the flow of fluid, particularly one tube and / or one channel, and / or at least one means affecting the flow of fluid, particularly one valve means and / or one pump. The means enabling the flow of fluid or the means affecting the flow of fluid are in fluid communication with the stormwater source, the influent sampling means, the biofiltration means, the effluent sampling means and / or the well means. Optionally, the space is of such a size that a person can enter and operate, maintain, and / or replace the aforementioned means contained therein.

[0027] In order to further improve the water quality inside the stormwater management system and ultimately downstream thereof, at least one aerator means is provided within the influent sampling means and / or the biofiltration means and / or the effluent sampling means. In a highly advantageous aspect, at least two aerator means are provided in the biofiltration means. The aerator is adapted to increase the oxygen concentration. In particular, when the aerator means is located in the biofiltration means, the oxygen concentration in the biofilter feed, i.e., the influent stormwater, increases. The aerator means is adapted to support the coprecipitation of iron and other metals, the removal of organic matter, the conversion of nutrients, and to distribute water over any desired surface, particularly the entire surface of the biofiltration means.

[0028] According to a further embodiment of the present invention, at least one aerator means is provided with at least one control means for controlling the aerator means and / or at least one communication means adapted to communicate with at least one of the control means disclosed above.

[0029] Alternatively or additionally, at least one oil separation means is provided in the influent sampling means and / or the biological filtration means. Optionally, at least one oil separation means can be provided in the effluent water retention means. According to a further embodiment, at least one oil separation means is provided with at least one sensor means for sensing at least the physical and / or chemical properties of the oil separation means and / or at least one control means for controlling the oil separation means and / or at least one communication means adapted to communicate with at least one of the control means disclosed above.

[0030] As will be appreciated, the amount of stormwater adapted to enter the stormwater inlet means varies particularly depending on meteorological conditions. In order to enable control of the inflow of stormwater within the stormwater inlet means, at least one water storage tank adapted to function as a stormwater buffer is provided in the middle of the fluid communication between the stormwater source and the stormwater inlet means.

[0031] According to yet another embodiment of the stormwater management system according to the present invention, at least one valve is provided which is adapted to at least temporarily allow, bypass, and / or block at least a portion of the stormwater, a portion of the inflow sump water, a portion of the biofiltered water, a portion of the outflow sump water, and / or the flow of other water adapted to enter the stormwater management system, flow through the stormwater management system, and / or exit the stormwater management system. This makes it possible to control the fluid flow of the stormwater and / or any other water entering the stormwater management system, inside the stormwater management system, and / or exiting the stormwater management system. In particular, the stormwater inflow means, inflow sump means, biofilter means, and / or outflow sump means can be closed completely or partially as needed. Alternatively or additionally, additional water supply pipes, ducts, or similar water supply means can be provided to direct additional water, especially fresh water, into the inflow sump means, biofilter means, and / or outflow sump means.

[0032] In an advantageous embodiment, at least one valve, at least one sensor, at least one control and / or at least one communication is located within the same structure. The structure is of any suitable type. In particular, the structure is a building, housing or container. In a particularly advantageous embodiment, the structure is the same structure that houses the inlet sump and / or outlet sump. This minimizes the space required for the filtration means according to the present invention and further simplifies maintenance of the stormwater management system in particular.

[0033] This is especially true when at least one valve, at least one sensor means, at least one control means and / or at least one communication means are located in the space between the inlet sump means and the outlet sump means and outside of them. In a more advantageous embodiment, the inlet sump means and the outlet sump means are symmetrically positioned with respect to the space.

[0034] To further enhance the quality and operability of the heavy rainwater management system according to the present invention, at least one well means is in fluid communication with the outflow sump means and forms part of the heavy rainwater management system.

[0035] To further enhance the quality and operability of the heavy rainwater management system according to the present invention, the well means are adapted to discharge water to filtration means, particularly biological filtration means, and / or water utilization means, particularly buildings, and / or heavy rainwater sources, particularly heavy rainwater sewers. In other words, the clean water from the well means can be distributed as needed to filtration means, such as inlet sump means, biological filtration means, and / or outlet sump means, water utilization means, and / or rainwater sources, particularly for washing or watering purposes.

[0036] In summary, the following advantages are associated with the invention disclosed above: The stormwater management system mitigates stormwater-related events in a way that achieves a compact and nature-based management system design. Particulate dissolved pollutants are reliably removed, and the water flow rate within the stormwater management system is adjusted to promote biofiltration. The infiltration flow rate, oxygen level in the stormwater for infiltration, oxidation-reduction conditions in the biofiltration means for metal complexation, nutrient and carbon assimilation, and conditions for pathogen removal are further adjusted to match the hydraulic capacity of the receiving well means. Finally, the quality of the untreated and treated stormwater is monitored to protect the water entering the well means.

[0037] Embodiments of the present invention are further described by detailed descriptions and accompanying drawings.

[0038] The present invention will be described in further detail with reference to the accompanying drawings. The drawings illustrate practical embodiments of the present invention, but are not to be construed as limiting the scope of the invention. [Brief explanation of the drawing]

[Figure 9] This is a schematic diagram of a structure having a space between the inlet sump and the outlet sump. [Modes for carrying out the invention]

[0040] Figure 1A symbolically illustrates the heavy rainwater management system 1, which consists of an inlet sump 5, a biological filtration system 10, and an outlet sump 15. The inlet sump 5, the biological filtration system 10, and the outlet sump 15 form a filtration system 20.

[0041] Each of the inflow sump means 5, the biological filtration means 10, and the outflow sump means 15 is provided with a sensor means 25, a control means 30, and a communication means 35, respectively.

[0042] The inflow sump means 5 is provided with a rainwater inlet means 40 that is in fluid communication with a rainwater source 45. The rainwater source can be a reservoir in the form of a pond, canal, or similar artificial container. As indicated by arrow I, rainwater can flow from the rainwater sewer 45 into the inflow sump means 5 through the rainwater inlet means 40, for example, through a pipe. The quality and / or quantity of rainwater upstream of the rainwater inlet means 40 is sensed by a sensor means 25 of the inflow sump means 5. If the quality and / or quantity deviates from a preset value calculated and / or stored in the control means 30 and / or transmitted to the control means 30 via the communication means 35 by an external calculation or storage means (not shown in Figure 1A), the control means 30 reduces the flow from the rainwater sewer 45 to the inflow sump means 5, or, in some cases, shuts off the rainwater inlet means 40. In this case, the valve means 50, for example, a two-way valve, is adapted to bypass the rainwater inlet means 40 to undesirable rainwater, as indicated by arrow II. The valve means 50 is operationally connected to the sensor means 25 and the control means 30 that it controls.

[0043] Although Figure 1A shows the valve mechanism 50, please note that it can be ignored in different embodiments of the heavy rainwater management system 1. This embodiment corresponds to the embodiment shown in Figure 1A, except for the valve mechanism 50 and its corresponding arrow II, and therefore is not shown in another figure.

[0044] If the quality and / or quantity of the rainwater at the upstream position of the rainwater inlet means 40, as sensed by the sensor means 25 of the inflow sump means 5, corresponds to the aforementioned preset value, then the rainwater can enter the inflow sump means 5 via the rainwater inlet means 40 and be physically and / or chemically treated inside the inflow sump means 5, as indicated by arrow III and as described below. The physically and / or chemically treated rainwater is called inflow sump water. The inflow sump water exits the inflow sump means 5 through an inflow sump water outlet means 55, for example, a pipe, located downstream of the rainwater inlet means 40 and in the direction of the inflow sump water inlet means 60 of the biological filtration means 10, as indicated by arrow IV.

[0045] The quality and / or quantity of the inflow sump water upstream of the inflow sump water inlet means 60 is sensed by the sensor means 25 of the biological filtration means 10. If the quality and / or quantity deviates from a preset value calculated and / or stored in the control means 30 and / or transmitted to the control means 30 of the biological filtration means 10 via the communication means 35 by an external calculation or storage means (not shown in Figure 1A), the control means 30 reduces the flow from the inflow sump water outlet means 55 to the inflow sump water inlet means 60, for example, a pipe, or, in some cases, shuts off the inflow sump water inlet means 60. In this case, a valve means 65, for example, a two-way valve, is adapted to bypass the inflow sump water inlet means 60 to undesirable inflow sump water, as indicated by arrow V. The valve means 65 is operationally connected to the sensor means 25 and to the control means 30 of the biological filtration means 10 that it controls. Note that the valve means 65 may be located within the inflow sump means 5 (not shown in this figure).

[0046] Although not shown in this figure, it should be noted that in different embodiments of the heavy rain water management system 1, the sensor means 25, the control means 30, and / or the communication means 35 can be ignored.

[0047] If the quality and / or quantity of the inflow sump water at the upstream position of the inflow sump water inlet means 60, as sensed by the sensor means 25 of the biological filtration means 10, corresponds to the aforementioned preset value, then, as indicated by arrow VI, the inflow sump water can enter the biological filtration means 10 through the inflow sump water inlet means 60, for example, a pipe. The water is then adjusted in the form of a saturation zone in the biological filtration means 10, as indicated by arrow VII and described below. The physically and / or chemically treated inflow sump water is called biofiltered water. The biofiltered water exits the biological filtration means 10 through a biofiltered water outlet means 70, for example, a pipe, located downstream of the inflow sump water inlet means 60, in the direction of the biofiltered water inlet means 75, for example, a pipe, of the outflow sump means 15, as indicated by arrow VIII.

[0048] The quality and / or quantity of the biofiltered water upstream of the biofiltered water inlet means 75 is sensed by the sensor means 25 of the inlet sump means 15. If the quality and / or quantity deviates from a preset value calculated and / or stored in the control means 30 and / or transmitted to the control means 30 of the outlet sump means 15 via the communication means 35 by an external calculation or storage means (not shown in Figure 1A), the control means 30 reduces the flow from the biofiltered water outlet means 70 to the biofiltered water inlet means 75, or, in some cases, shuts off the biofiltered water inlet means 75. In this case, the valve means 80, for example, a two-way valve, is adapted to bypass the biofiltered water inlet means 75 to undesirable biofiltered water, as indicated by arrow IX, so that the bypassed water flows back into, for example, a heavy rain source 45. The valve means 80 is operationally connected to the sensor means 25 and to the control means 30 of the outlet sump means 15 which it controls.

[0049] If the quality and / or quantity of the biofiltered water at the upstream position of the biofiltered water inlet means 75, as sensed by the sensor means 25 of the outflow sump means 15, corresponds to the aforementioned preset value, then the biofiltered water can enter the outflow sump means 15 through the biofiltered water inlet means 75, as indicated by arrow X. The water is then physically and / or chemically treated inside the outflow sump means 15, as indicated by arrow XI and as described below. The physically and / or chemically treated biofiltered water is called the outflow sump water. The outflow sump water exits the outflow sump means 15 through the outflow sump water outlet means 85, for example, a pipe, located downstream of the biofiltered water inlet means 75, for example, a pipe, in the direction of the outflow sump water inlet means 90 of the well means 95, for example, a pipe, as indicated by arrow XII.

[0050] Note that the valve mechanism 80 may be located on the outflow sump mechanism 15 (not shown in this figure).

[0051] The quality and / or quantity of the outflow sump water upstream of the outflow sump water inlet means 90 is sensed by the sensor means 25 of the well means 95. If the quality and / or quantity deviates from a preset value calculated and / or stored in the control means 30 and / or transmitted to the control means 30 of the well means 95 via the communication means 35 by an external calculation or storage means (not shown in Figure 1A), the control means 30 reduces the flow from the outflow sump water outlet means 85 to the outflow sump water inlet means 90, or, in some cases, shuts off the outflow sump water inlet means 90. In this case, the valve means 100, for example, a two-way valve, is adapted to bypass the outflow sump water inlet means 90 to undesirable outflow sump water, as indicated by arrow XI. The valve means 100 is operationally connected to the sensor means 25 and to the control means 30 of the well means 95 that it controls.

[0052] If the quality and / or quantity of the outflow sump water at the upstream position of the outflow sump water inlet means 90, as sensed by the sensor means 25 of the well means 95, corresponds to the aforementioned preset value, then the outflow sump water can enter the well means 95 through the outflow sump water inlet means 90, as indicated by arrow XIV. The water is stored in the well means 95 and can be used as needed.

[0053] Note that the valve mechanism 100 may be located in the outflow sump mechanism 15 or the well mechanism 95 (not shown in this figure).

[0054] Figure 1B symbolically illustrates an alternative embodiment of the heavy rainfall management system 1 shown in Figure 1A. The heavy rainfall management system 1 shown in Figure 1B basically contains the same elements as the heavy rainfall management system shown in Figure 1A. Therefore, for the sake of simplicity, we will refer to the explanation of Figure 1A, but will not repeat the explanation itself here.

[0055] However, the heavy rainwater management system 1 shown in Figure 1B includes a water storage tank 105 downstream of the heavy rainwater sewer 45 and upstream of the inflow sump means 5. Specifically, the water storage tank 105 is interposed between the valve means 50 and the heavy rainwater inlet means 40. Sensor means 25, control means 30 and communication means 35 are provided, respectively, and these are functionally connected to the sensor means 25, control means 30 and communication means 35 of the inflow sump means 5, biological filtration means 10 and outflow sump means 15. The water storage tank 105 has a heavy rainwater inlet means 110, for example, a pipe, through which heavy rainwater can pass when it enters the water storage tank 105. Downstream of the heavy rainwater inlet means 110, a heavy rainwater outlet means 115, for example, a pipe, is provided, which is in fluid communication with a valve means 120, for example, a two-way valve. The valve means 120 is further in fluid communication with the heavy rainwater inlet means 40 of the inflow sump means 5.

[0056] The quality and / or quantity of rainwater upstream of the rainwater inlet means 110 is sensed by the sensor means 25 of the reservoir 105. If the quality and / or quantity deviates from a preset value calculated and / or stored in the control means 30 and / or transmitted to the control means 30 via the communication means 35 by an external calculation or storage means (not shown in Figure 1A), the control means 30 reduces the flow from the rainwater sewer 45 to the reservoir, or, in some cases, shuts off the rainwater inlet means 110. In this case, the valve means 50 is adapted to bypass the rainwater inlet means 110 to undesirable rainwater, as indicated by arrow II. The valve means 50 is operationally connected to the sensor means 25 and the control means 30 which it controls.

[0057] Although Figure 1B shows the valve mechanism 50, please note that it can be ignored in different embodiments of the heavy rainwater management system 1. This embodiment corresponds to the embodiment shown in Figure 1B, except for the valve mechanism 50, and is therefore not shown in another figure.

[0058] If the quality and / or quantity of the rainwater at the upstream position of the rainwater inlet means 110, as sensed by the sensor means 25 of the water storage tank 105, corresponds to the aforementioned preset value, the rainwater can enter the water storage tank 105 via the rainwater inlet means 110. The water storage tank 105 functions as a buffer and can store a desired amount of rainwater. If necessary, the rainwater exits the water storage tank 105 through the rainwater outlet means 115.

[0059] The quality and / or quantity of rainwater downstream of the rainwater outlet means 115 is sensed by the sensor means 25 of the inflow sump means 5. If the quality and / or quantity deviates from a preset value calculated and / or stored in the control means 30 and / or transmitted to the control means 30 via the communication means 35 by an external calculation or storage means (not shown in Figure 1B), the control means 30 reduces the flow from the reservoir 105 to the inflow sump means 5, or, in some cases, shuts off the rainwater inlet means 40. In this case, the valve means 120 is adapted to allow undesirable rainwater to bypass the rainwater inlet means 40, as indicated by arrow XV. The valve means 120 is operationally connected to the sensor means 25 and to the control means 30 of the inflow sump means 5 which it controls.

[0060] If the quality and / or quantity of the rainwater upstream of the rainwater inlet 40, as sensed by the sensor 25 of the inflow sump 5, corresponds to the aforementioned preset value, the rainwater can enter the inflow sump 5 through the rainwater inlet 40, as indicated by arrow XVI. The physically and / or chemically treated rainwater then becomes the inflow sump water, as described with reference to Figure 1A and also indicated by arrow III.

[0061] As can be understood from the above, each embodiment shown in Figures 1A and 1B includes a sensor 25, a control 30, and a communication 35 for each of the inflow sump 5, the biological filtration 10, the outflow sump 15, and the well 95. This enables very close sensing, control, and communication within the heavy rainwater management system 1 and / or with external technical devices (not shown).

[0062] However, as can be seen in the embodiment of the heavy rainwater management system 1 shown in Figure 2, a smaller number of sensor means 25, control means 30, and communication means 35 may be provided instead. Here, only the inlet sump means 5, the outlet sump means 15, and the well means 95 are provided with sensor means 25, control means 30, and communication means 35, while the biological filtration means 10 is not provided with sensor means 25, control means 30, and communication means 35. Also, as indicated by arrows V and XI, valve means 65 and 100 are provided only on the inlet sump means 5 and the outlet sump means 15 so that the fluid can bypass the biological filtration means 10 and the well means 95, while the biological filtration means 10 is not provided with valve means. The well means 95 is in fluid communication with an additional reservoir 123. The fluid flow between the well means 95 and the reservoir 123 can be allowed, limited, or suppressed by a valve means 124 controlled by an additional sensor means (not shown in this figure).

[0063] Figures 1A and 2 show the heavy rainwater management system 1 in block diagram form, while Figure 3 is an isometric view of the filtration system 20 of the heavy rainwater system 1. The inflow sump means 5 is designed as structure 125, and the outflow sump means 15 is designed as a different structure 130. Structures 125 and 130 are separated from each other but are located within a connecting structure 135 such that a space 140 is formed between structures 125 and 130. Furthermore, the inflow sump means 5 and the outflow sump means 15 are positioned symmetrically with respect to the vertical axis LA of the biological filtration means 10.

[0064] A hatch 137 in the ceiling 138 of structure 135 provides access to space 140, for example, for maintenance. According to this exemplary embodiment of the present invention, structures 125, 130, and 135 are made of concrete. The biological filtration means 10 is adjacent to structure 135 and includes its own structure 145. However, it should be noted that structures 135 and 145 can also be provided as a single unit. Three aerators 150 are evenly distributed over the entire length of the biological filtration means 10, each extending laterally to the biological filtration means 10 over a portion of its width. As can be seen in Figure 3, the filtration system 20 requires only a small amount of space.

[0065] Figure 4 is a schematic perspective view of the inflow sump means 5. As shown, the structure 125 is essentially cubic in shape and has a floor 155 and four side walls 160 extending upward from the floor 155. The structure 125 is enclosed by a ceiling element 165 having a hatch 170, which can be opened and closed to allow easy access to the structure 125. The containers for the sensor means 25, control means 30 and communication means 35 of the inflow sump means 5 are located above the ceiling element 165. Note that, although not shown in this figure, the sensor means 25, control means 30 and communication means 35 of the inflow sump means 5 may be located inside the structure 125. In this case, a container may not be provided.

[0066] Inside the structure 125 is a first baffle 175 extending upward from the floor 155 towards the ceiling element 165 and along the entire length of the side wall 165 in the width direction of the inflow sump 5, dividing the lower part of the inflow sump 5 into two spaces 176, 177 that are fluidly separated from each other. In other words, the first baffle 175 is a wall-like element that divides the lower part of the inflow sump 5 into two pools that are separated from each other. The first baffle 175 is made of the same material as the structure 125. Above the first baffle 175 is a screen 180 that is in direct contact with the first baffle, and this screen also extends upward towards the ceiling element 165 and along the entire length of the side wall 165 in the width direction of the inflow sump 5. The screen 180 contains a filter material and has a handle 185 that allows it to be removed and reinstalled or replaced, for example, for cleaning. The first baffle 175 and screen 180 are located downstream of the torrential rain inlet means 40. The torrential rain inlet means 40 is shown symbolically in Figure 4, but can be easily understood from the arrow I representing the torrential rain flowing into the inflow sump means 5.

[0067] Upstream of the first baffle 175 and screen 180 is a second baffle 190, which extends upward from the floor 155, but at a distance from the floor, towards the ceiling element 165. Unlike the first baffle 175, this baffle does not extend along the entire length of the side wall 165 in the width direction of the inflow sump means 5, but is offset from one side of the side wall 160. The height of the second baffle 190 is greater than the height of the first baffle 175.

[0068] As indicated by arrow III, the incoming rainwater is treated in multiple stages: after entering the second space 177, debris (not shown in this figure) may settle and accumulate on the floor of the second space 177. If the water level of the rainwater is higher than the height of the first baffle 175, this portion of the rainwater flowing through the screen 180 is filtered by the filter material within it and flows into the first space 176. In the first space 176, debris (not shown in this figure) that did not accumulate in the second space 177 and was filtered by the screen 180 may settle and accumulate. The treated water exits the inflow sump means 5 in the form of inflow sump water via the inflow sump water outlet means 55, as indicated by arrow IV.

[0069] Figure 5 is a schematic perspective view of the biological filtration means 10. As shown, the biological filtration means 10 has a floor 195 and four side walls 200 extending upward from the floor 195, thereby giving the biological filtration means 10 a trough-like shape. The floor 195 and the side walls 200 are covered with a geotextile liner (not shown). The floor 195, the side walls 200, and the liner are designed to provide a waterproof barrier. A first layer L1 of filter material (not shown here), which is sand of a specific quality according to this embodiment, covers the floor 195. A second layer L2 of further filter material (not shown here), which is sand of a specific quality different from the filter material of layer L1, is located on top of layer L1. A third layer L3 of further filter material (not shown here), which is sand of a specific quality different from the filter material of layers L1 and L2, is located on top of layer L2.

[0070] Plants (not shown here) with roots that can reach the first layer L1 and the floor 195 through the material of the second layer L2 are placed on layer L2. Finally, the biofiltration means 10 according to this embodiment includes a container for the sensor means 25, control means 30 and communication means 35 of the inflow sump means 5. Note that, although not shown in this figure, the sensor means 25, control means 30 and communication means 35 may be located at the end of the biofiltration means 10. In this case, a container may not be provided. Inflow sump water can enter the biofiltration means 10 via the inflow sump water inlet means 60, as indicated by arrow IV. The inflow sump water is treated by the filter material and plants in layers L1 and L2. The treated water passes through a horizontally positioned collection pipe (not shown) and exits the biofiltration means 10 via the biofiltration water outlet means 70 in the form of biofiltered water, as indicated by arrow VII.

[0071] Figure 6 shows a schematic diagram of the aerator 150. The aerator 150 according to this exemplary embodiment is designed as an overflow aerator and has a first support 205 and a second support 210 that can be fixed to the floor 195 of the biological filtration system 10. The two supports 205, 210 are fitted so that their height can be adjusted, for example by screw adjusters, in order to make the aerator 150 horizontal to the floor 195. An inlet pipe 215 is located between the two supports 205, 210, which is in fluid communication with the water in the biological filtration system 10. A schematic outlet pipe 220 is located downstream of the inlet pipe 215 and is in fluid communication with the inlet pipe. Because the outlet pipe essentially extends along the entire length of the aerator 150 and has numerous openings (not shown in this figure), the water in the biofiltration system 10 can be transported through the inlet pipe 215 by a pump (not shown) as indicated by arrow XV, distributed by the outlet pipe 220 along the entire length of the aerator 150, and sprayed onto the water in the biofiltration system 10 as indicated by arrow XVI.

[0072] Figure 7 is a schematic perspective view of the outflow sump 15. As shown, the structure 130 is essentially cubic in shape and has a floor 225 and four side walls 230 extending upward from the floor 225. The structure 130 is enclosed by a ceiling element 235 having a hatch 240, which can be opened and closed to allow easy access to the structure 130. The containers for the sensor means 25, control means 30 and communication means 35 of the outflow sump 15 are located above the ceiling element 235. Note that, although not shown in this figure, the sensor means 25, control means 30 and communication means 35 of the inflow sump 5 may be located inside the structure 130. In this case, a container may not be provided.

[0073] Inside the structure 130 is an adjustable dam 245 that extends upward from the floor 225 towards the ceiling element 235 and along the entire length of the side wall 230 in the width direction of the outflow sump means 15, dividing the lower part of the outflow sump means 15 into two separate spaces 250, 255. The dam 245 is located downstream of the biofiltered water inlet means 75. The biofiltered water inlet means 75 is shown symbolically only in this Figure 7, but can be easily understood from arrow X, which indicates that the biofiltered water flows into the outflow sump means 15. As indicated by arrow XI, the incoming biofiltered water can flow from the first space 250 into the second space 255, but a certain amount of biofiltered water remains in the first space 250. The water exits the outflow sump means 15 in the form of outflow sump water via the outflow sump water outlet means 85, as indicated by arrow XII.

[0074] Figure 8 is a block diagram of yet another embodiment of the heavy rainwater management system 1 according to the present invention. The inlet sump means 5, space 140, and outlet sump means 15 form a connecting structure 135. The biological filtration means 10 is positioned alongside the connecting structure in a separate structure 145. Each of the inlet sump means 5, space 140, outlet sump means 15, and biological filtration means 10 is provided with a sensor means 25, a control means 30, and a communication means 35, respectively. Note that the flow of fluids such as heavy rainwater corresponds to that shown in the previous figures, and that all the arrows and the designs of the inlet sump means 5, space 140, outlet sump means 15, and biological filtration means 10 have been omitted for simplification unless explicitly stated in the following parts of this specification.

[0075] As already explained with reference to Figure 1, the stormwater sewer 45 is in fluid communication with the inflow sump 5, as indicated by arrow I. The incoming stormwater is processed inside the inflow sump 5, as previously described and also indicated by arrow III. The processed stormwater exits the inflow sump 5 in the form of inflow sump water and is further processed in the biofiltration 10, as indicated by arrow VII. The biofiltered water thus produced enters the outflow sump 15 and exits the outflow sump 15 in the direction of the well 95, via space 140 to the well 95, as indicated by arrow XIV. For this purpose, at least one pipe (not shown in this Figure 8) is installed in space 140 and in the area outside space 130 to the well 95. The well has a sensor 25, a control 30, and a communication 35.

[0076] The well means 95 is further provided with an outlet pipe 260 equipped with a valve means 265 in the downstream direction. The first pipe 270 and the second pipe 275 are connected to the valve means 265 independently of each other. In this embodiment, the valve means 265 communicates with the sensor means 25, control means 30 and communication means 35 of the well means 95. Downstream, the first pipe 270 is in fluid communication with the user side 280 so that water from the well means 95 can be utilized. The second pipe 275 directs water from the well means 95 to the biofiltration means 10 through space 140 so that water from the well means 95 can be utilized by the biofiltration means, as indicated by arrows XVII and XVIII. As indicated by arrow XIX, the water can be redirected from the biofiltration means 10 to the user side 280 through space 140 by another pipe 285.

[0077] Although not shown in this figure, the water from the well 95 can also be directed to the inflow sump 5 and / or outflow sump 15 instead of the biological filtration 10. Additionally or alternatively, the water from the well 95 can be directed directly to the heavy rain sewer 45 (not shown in Figure 8).

[0078] Figure 9 is a schematic diagram of the connecting structure 135, which includes a space 140 between the inlet sump 5 and the outlet sump 15, as previously described with reference to Figure 3. This figure shows a portion of the side wall 160 of the inlet sump 5 adjacent to the space 140, and a portion of the side wall 200 of the outlet sump 15 adjacent to the space 140. As shown in the figure, there are several devices adapted to affect the fluid flow between the inlet sump 5 and the biological filtration means 15, and between the outlet sump 15 and the well means 95, respectively.

[0079] The inflow sump water is sent to pipe 295 by pump 290. Pipe 295 is equipped with a control means 30 and a valve 65 for the inflow sump means 5. A sensor 25 for the inflow sump means 5 is located in the bypass pipe 300, which is also adapted to receive the inflow sump water. As described above, if the quality of the inflow sump water corresponds to a preset value, the inflow sump water can enter the biofiltration means 10 via the inflow sump water inlet means 60, as indicated by arrow VI. If the quality of the inflow sump water does not correspond to a preset value, the valve 65 is shut off according to the control means 30. The inflow sump water can then exit tube 295, as indicated by arrow V.

[0080] In a similar manner, the outflow sump water is sent to the pipe 310 by the pump 305. The pipe is equipped with a control means 30 and a valve 100 for the outflow sump means 5. The sensor 25 of the outflow sump means 5 is located in the bypass pipe 315, which is also adapted to receive the outflow sump water. As described above, if the quality of the outflow sump water corresponds to a preset value, the outflow sump water can enter the well means 95 as indicated by arrow XIV. If the quality of the outflow sump water does not correspond to a preset value, the valve 100 is shut off according to the control means 30. The outflow sump water can exit the tube 310 as indicated by arrow XIII.

[0081] It will be understood that the aforementioned pipes, pumps, sensor means, and control means are all located within space 140. Therefore, they are easily accessible. In addition, any communication means 35 (not shown here) can be provided within space 140.

[0082] It should be noted that the heavy rainwater management system 1 may include piping, numerous valves, and numerous pumps to enable the flow of heavy rainwater fluid from the heavy rainwater sewer 45 to the well means 95 and the user side 280 (not shown in Figures 1 to 8 for simplification).

[0083] Furthermore, it should be noted that the number, location, and type of the sensor means 25, control means 30, and communication means 35 may differ from those shown in Figures 1 to 8. For example, the number of sensor means 25 can be increased significantly more than the number of control means 30 or communication means 35. In particular, a single control means 30 or a single communication means 35 can be provided that is operationally connected to a large number of sensor means 25.

[0084] As an example, the sensor means 25 of the inflow sump means 5 may include a water level sensor and / or a water quality sensor, such a sensor adapted to sense the presence of oil, hydrocarbons, the electrical conductivity or turbidity of water. The sensor means 25 of the biological filtration means 10 may include an overflow sensor or a water quality sensor. The sensor means of the outflow sump means 15 may include a water level sensor and / or a water quality sensor, such a sensor adapted to sense, for example, the pH and nutrients of water. Finally, any of the sensor means 25 may include a temperature sensor adapted to measure water temperature and / or air temperature.

[0085] Furthermore, for example, the control means 30 for the inflow sump means 5, the biofiltration means 10 and / or outflow sump means 15 can be adapted to control the level, volume, flow rate, turbidity, time, electrical conductivity of the water and / or amount of dissolved oxygen upstream of the control means 30 for the inflow sump means 5, the biofiltration means 10 and / or outflow sump means 15, and / or downstream of the control means 30 for the inflow sump means 5, the biofiltration means 10 and / or outflow sump means 15.
