EGRP Stormwater Infiltration System

Energy-Passive Groundwater Recharge (EGRP) System

EGRP is an engineered system designed to restore stormwater infiltration capacity in poor soils (C & D), maximizing groundwater recharge and runoff reduction to meet water quality requirements and mitigate peak flows from developed sites.

The devices are installed in a sub-surface network surrounding permeable stormwater storage areas. By creating flow paths between soil layers and restoring moisture content to the soils, stormwater infiltration capacities can be improved by a factor of 5 to 10 times the existing rates. Designed and constructed with a performance warranty that guarantees the results, EGRP works well with ponds, bioretention systems, R-Tank, and other subsurface storage systems.
