An underground water storage system has a system for preventing water invasion into the near surface soil layers, thereby preventing water intrusion which may be detrimental to desired surface uses for the land, such as agricultural, recreational, residential or commercial uses.

Individual four-sided shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant four-sided tiling shape for maximized structural strength and material use efficiency. Internal four-sided shaped modules are assembled and encased by external four-sided shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal four-sided shaped modules drain into four-sided shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.

In various embodiments, the disclosure relates to a system for locating storm and/or waste water to a subsurface region. The system can be sized to replace, in some instances, retention ponds and to increase developable square footage on a region of land. The system can include a conduit for directing a volume of storm and/or waste water to a subsurface region located at least as deep as the aquifer layer. The system can be sized to handle a volume of water generated during a 100 year storm. In certain embodiments, the subsurface region is located directly below a land structure (e.g., a building structure).

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 system and method for an underground stormwater storage system which may comprise a pit, a structure, and a liner. The structure may be disposed within the center of the pit and surround by the porous backfill and wherein outlets are disposed on the crown of the structure. A liner may form the outer layer of the pit. A method for releasing stormwater may comprise capturing stormwater from a surface, containing the stormwater within a structure, releasing a volume of the stormwater from the structure and draining an additional volume of the stormwater from the crown of the structure from an outlet when the structure is capturing more stormwater than it is releasing.
