The EGRP® dramatically increases the rate of infiltration, enhancing natural conditions and improving areas where infrastructure has created impervious areas. The EGRP® helps rebalance groundwater conditions by establishing new ways water can move to, and through, the soil. The EGRP® enhances infiltration by moving water more effectively and efficiently through the soil matrix and into the water table.
Each EGRP® has a central core with four crescents around the central core. EGRP®s are made of polyethylene plastic and are chemically inert so as not to degrade in the soil. The EGRP® has a smooth surface restricting silting and or clogging. Each EGRP® is capped. The cap closes the system so as not to act as a conduit for water free flow. The EGRP®s are placed either the fully or partially in the vadose zone two to three feet below the surface in lengths of 5’ (1.524m), 10’ (3.048 m), 20’ (6.096 m) and 40’ (12.192 m). The EGRP® is 1 ¼” (31.75 mm) in diameter.
