RECHARGE
What is Recharge?
Recharge is the process of capturing runoff from roof tops and surrounding areas and diverting it to the local groundwater table. Groundwater is naturally recharged by precipitation. However, in areas where there are paved surfaces the water will runoff into storm drains instead of going back into the ground to replenish the groundwater table.

What can property owners do?
Property owners can install a recharge structure (such as a dry well), porous pavement, and/or pervious pipes in yards or appropriate parking areas. Multiple examples are provided below in the different types of recharge section.
