A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater, in some cases greywater or water used in a groundwater heat pump. It is a gravity-fed , vertical underground system that can capture surface water from impervious surfaces , then store and gradually infiltrate the ...
Since then, over 40 ASR wells have been installed for many different municipalities. These wells range in depths from 1,000 ft (300 m) to 3,000 ft (910 m) below ground surface, with injection rates commonly between 100 US gal (380 L; 83 imp gal) and 500 US gal (1,900 L; 420 imp gal) per minute (gpm) per well.

Both problems, Nelson’s dry well and Springman’s muddy water, are coming from the same source: a court-ordered extreme drawdown of Lookout Point and Green Peter reservoirs meant to save ...
A septic tank consists of one or more concrete or plastic tanks of between 4,500 and 7,500 litres (1,000 and 2,000 gallons); one end is connected to an inlet wastewater pipe and the other to a septic drain field. Generally these pipe connections are made with a T pipe, allowing liquid to enter and exit without disturbing any crust on the surface.
A lone pickup truck barreled down East Army Post Road on a weekday afternoon. Sunshine refracted through the 500-gallon water drum the truck hauled, shimmering on the barren farm fields and ...
A non-exempt well is a well capable of producing more than 17.36 gallons per minute, and must submit semi-annual water well production reports to the District at a rate of $0.155 per 1,000 gallons.

A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time.
