An example system is configured to manage the storage of water underground using a sensor-based grid system. The example system includes wells, each of which is between a surface and an underground formation capable of storing water received from the surface. The example system includes pumps, at least of which is associated with each well to force water from the surface, through the well, into the underground formation. The example system includes sensors, at least of which is associated with each well. The sensors are configured to communicate sensor data wirelessly. The example system also includes a computing system configured to receive sensor data from each of the sensors and to control operations of one or more of the pumps based on the sensor data.

A storm water drain system and methods of assembling the same are provided. The system can be arranged to provide a water management function such as retention, detention, conveyance, or infiltration. The system can include a plurality of support modules positioned adjacent to one another to form a top deck, a bottom deck, and an interior space between the top deck and the bottom deck. The plurality of support modules can include a support module that has a bottom corbel extending from an outer surface of the support module. The bottom corbel can be located within the interior space and have a surface that contacts a portion of the bottom deck.

The temporary storm water storage system comprises a storage tank, an inlet pump, an outlet pump, a graded top drain, a plurality of sensors, a timer, a first valve, a second valve, and a plurality of interconnecting pipes. The temporary storm water storage system may pump flood water from a street into the storage tank when flooding is detected by the plurality of sensors. The temporary storm water storage system may pump the flood water from the storage tank into the street after a predetermined time interval once the flooding has subsided. The flood water pumped from the storage tank to the street may be drained from the street via one or more catch basins into a storm drain.

A method for mitigating flooding in existing coastal plain areas includes: A dyke (or dykes) is (are) set/built on seabed outside partial existing coastline of an existing coastal plain area to form an enclosed area; the enclosed area, together with the dyke(s), the reservoir inlet(s) and outlet(s), constitutes a reservoir for containing rainwater; or, part(s) of the enclosed area is (are) of a reclamation area (or reclamation areas). Before the start of forecast heavy rainfall or continuous rainfall, the water level in the reservoir is lowered in advance and the water level of water area for containing rainwater in the existing coastal plain is also pre-lowered, so effective storage capacity for containing rainwater against flooding caused by rainfall in the locality is substantially increased. The present invention is applicable for the flooding control works, reclamation works, roads and highways and their integrated works in existing coastal plain areas.

A device for vehicle hindrance and rainwater treatment including a vehicle hindrance body and a well pit. The vehicle hindrance body includes a lower sidewall, the well pit includes a top opening, and the lower sidewall encloses the top opening. The lower sidewall includes a plurality of water inlet holes. The well pit includes an upper part, a lower part, and a partition disposed between the upper part and the lower part. The partition includes a plurality of leaking holes. The upper part of the well pit includes an outer ring belt filled with a rainwater pretreatment filler, a center ring belt filled with soil, and a rainwater collection ring belt disposed between the outer ring belt and the inner ring belt. The lower part includes a water-sand separating folded plate, a water-sand discharging channel, a rainwater collecting tank, and a rainwater storage chamber.

A vacuum sewage system includes a collection station, a variable speed vacuum pump, a variable speed drive, a control system, a sewage pump, a collection tank, a valve pit, a first conduit extending from the collection station to the valve pit, a second conduit extending from the valve pit and terminating in a closed end, a sensor located adjacent the closed end of the second conduit, and a valve located in the valve pit for selectively permitting sewage and waste water to flow from the valve pit toward the collection station upon activation of the valve. The control system, variable speed drive and sensor may be utilized to adjust the vacuum level and vacuum level range at the collection station so as to reduce the speed and operation time of the variable speed vacuum pump while maintaining the desired vacuum level in the vacuum sewage system.

Sewage flowing into a second water branching device is accurately controlled to separate into the following: sewage with a maximum sewage volume that can be discharged into a public water body W, the sewage sequentially passing through a first regulating tank, a first orifice, a second regulating tank, a second orifice, a third regulating tank and a third orifice to flow into a second discharge pipe; and sewage with an excess sewage volume, the sewage overflowing first to third overflow weirs to flow into an inflow pipe for a regulating reservoir.
