Groundwater Recharge


Managed Aquifer Recharge (MAR) uses reservoirs, ponds, or spreading basins to hold water and allow the water percolate into the ground.


The use of floodwater for managed aquifer recharge (FloodMAR) is an increasingly popular method to replenish groundwater. The process diverts floodwater to reservoirs, ponds, spreading basins, or submerges farmland to allow the water to percolate into the ground.

Dry Wells

As the name implies, dry wells are rock filled borings that do not connect to the aquifer. Dry wells provide a direct connection for applied surface water to former water-bearing strata.
