A stormwater collection, treatment, and aquifer replenishment installation includes a stormwater drain for receiving surface stormwater, a dry well downwardly extending underground to an outlet proximate to a water table over an aquifer, a tank structure at least partially disposed underground and coupled with the stormwater drain and the dry well in stormwater communication, a stormwater treatment system enclosed within the tank structure between the stormwater drain and the dry well for converting surface stormwater into treated stormwater, the tank structure for conducting surface stormwater to the stormwater treatment system between the stormwater drain and the dry well, and the dry well for receiving and gravity feeding treated stormwater from stormwater treatment system to the outlet.

A distributed integrated water management system includes water source supply lines capable of being placed in fluid communication with a separate water source, water discharge lines capable of being placed in fluid communication with a separate water discharge destination, a water source and destination control manifold to allow selected water source supply lines to be placed in fluid communication with selected water discharge lines, and a storm water collection and distribution system which includes a storm water collection conduit to collect storm water runoff, and a plurality of sumps to receive storm water runoff from the storm water collection conduit. The storm water collection and distribution system further includes a collected storm water discharge line in fluid communication with the sumps, and the collected storm water discharge line can be placed in fluid communication with the plurality of water discharge lines via the water source and destination control manifold.

An engineering system for collecting and utilizing regional rainwater includes a rainwater collection system, a water quality treatment system, and a control and allocation system. The rainwater collection system includes a rainwater collection ditch for a hardened underlying surface, a barrier and a water storage tank. The water quality treatment system includes a filter system. The control and allocation system includes a water quality monitoring device, a water level monitor, a control gate and a water pump. The filter system is connected to the underlying surface through the rainwater collection ditch, and the filter system is connected to the water storage tank. The control gate is disposed between the filter system and the water storage tank. The water quality monitoring device and the water level monitor are disposed within the water storage tank. The water pump is used to drain water from the water storage tank.

A method of removing sediment from fluid flow within a storm water drain pit by deflecting flow entering the pit towards the side walls of the pit by one or more deflectors. This reduces the energy of the fluid flow and promotes settling of sediment within the catch pit. Each deflector is preferably of a concave form and may be located in a storm water drain pit bag or suspended. A removable catch basin receptacle for a storm water drain pit includes a container has a low flow outlet defining a fluid path for fluid at a first level within the container to a second level, higher than the first level, outside the container. An overflow path provides a fluid flow path out of the container at a level higher than the first or second level.

A distributed integrated water management system includes water source supply lines capable of being placed in fluid communication with a separate water source, water discharge lines capable of being placed in fluid communication with a separate water discharge destination, a water source and destination control manifold to allow selected water source supply lines to be placed in fluid communication with selected water discharge lines, and a storm water collection and distribution system which includes a storm water collection conduit to collect storm water runoff, and a plurality of sumps to receive storm water runoff from the storm water collection conduit. The storm water collection and distribution system further includes a collected storm water discharge line in fluid communication with the sumps, and the collected storm water discharge line can be placed in fluid communication with the plurality of water discharge lines via the water source and destination control manifold.

A reservoir withdrawal system is disclosed comprising a selectively-adjustable water intake positioned within a reservoir. The water intake is adapted to withdraw water from the reservoir at a desired depth using a telescoping conduit. A water transport system is in fluid communication with the water intake and with a water discharge. A controller allows an operator to selectively adjust the desired depth of the water intake.

A water storage and filtering system for capturing pollutants from pollution borne storm water. The water storage and filtering system comprises a subsurface basin, at least one tire bundle made from a plurality of substantially whole tires secured sidewall to sidewall, and a filler which substantially fills the unoccupied volume of the subsurface basin. Pollutants in the storm water are captured as sediment in the subsurface basin as a result of the filtration and storage effects of the combination of the filler and tire bundles. The subsurface basin is covered by a water-permeable structure and multiple hollow vertical support columns may be included to support the expected load on the top of the basin.

A liquid treatment system is provided having a vault that contains a treatment chamber and an outflow chamber. The treatment chamber may have a filtration media layer containing media that treats liquid as it descends through the filtration media layer, where it will accumulate in a porous layer or open space. The liquid will then be directed through the plurality of pipes to the outflow chamber, where the treated liquid is further directed to outside the system. Accumulated debris settled at the bottom of the treatment chamber may be flushed out by a spray bar.

A gravitational separator for a drainage system includes a collection cavity within which drainwater is collected. The collection cavity includes an exit; and a baffle is strategically arranged within the collection cavity for isolating a boundary region of the cavity interior from the central region thereof and for directing the flow of drainwater which moves through the boundary region along a desired flow path. In addition, an outlet control structure is disposed over the mouth of the exit and includes a sidewall having an opening through which drainwater which enters the mouth of the exit must enter so that as the drainwater enters the sidewall opening and moves into the mouth of the exit opening, the direction of flow of the drainwater is altered through at least 90 degrees.

The present invention relates to a device comprising a coherent manmade vitreous fibre substrate (MMVF substrate) and at least one first conduit (2) and at least one second conduit (3), each conduit having first and second open ends, wherein the MMVF substrate (1) comprises man-made vitreous fibres bonded with a cured binder composition, wherein the first open end of the first conduit and the first open end of the second conduit are each independently in fluid communication with the MMVF substrate, wherein the first conduit is at a greater height than the second conduit, wherein at least a portion of the MMVF substrate is disposed between the first and second conduits. The MMVF substrate provides for an increased water storage ability due to the hydrophilic behaviour of the substrate and its increased surface.
