DETENTION BASIN
A detention basin is a storm water management facility installed on adjacent to tributaries of rivers, streams, lakes or bays that is designed to protect against flooding and in some cases, downstream erosion by storing water for a limited period of a time. These basins are also called "dry ponds", "holding ponds" or "dry detention basins" if no permanent pool of water exists. Some detention ponds are also "wet ponds" in that they are designed to permanently retain some volume of water at all times. The basic form of detention basin is used to manage water quantity while having a limited effectiveness in protecting water quality, unless it includes a permanent pool feature. Detention basins are storm water best management practices (BMPs) that provide general flood protection and can also control extreme floods such as a 1 in 100-year storm event. The basins are typically built during the construction of new land development projects including residential subdivisions or shopping centers. The ponds help manage the excess runoff generated by newly-constructed impervious surfaces such as roads, parking lots etc.

RETENTION BASIN
A retention basin, is a type of best management practice (BMP) that is used to manage stormwater runoff to prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream or lake . Sometimes called a wet pond or wet detention basin, it is essentially an artificial lake with vegetation around the perimeter, and includes a permanent pool of water in its design.
It is distinguished from a detention basin, sometimes called a dry pond, which temporarily stores water after a storm, but eventually empties out at a controlled rate to a downstream water body.

RENEWABLE SUPPLIES VIA UNDERGROUND STORAGE
United states has an innovative program called the Underground Water Storage, Savings and Replenishment Program.
This program, which is managed by the Department of Water Resources, allows surface water and reclaimed water not needed today to be banked – stored underground – for future use.
Water is stored underground through two methods:-
Direct Recharge: In this method, water is delivered to specially constructed basins that facilitate the infiltration of water into the ground. The water percolates and eventually reaches the existing groundwater aquifer, storing the water underground for future use.
​
Indirect Recharge: Indirect recharge is performed at irrigation districts that are permitted by as groundwater savings facilities.
The concept is that irrigation districts with legal rights to pump groundwater can use CAP or reclaimed water in lieu of pumping groundwater. Thus, groundwater is "saved," hence the name "groundwater savings facility," and long-term storage credits are issued to the entity that delivered the CAP water or reclaimed water to the irrigation district.
