Water Group LLC

The Water Group LLC, is the Exclusive Representative of Parjana Distribution and the EGRP® Water Infiltration System.

Integrating Stormwater & Groundwater Management with the  EGRP®

 What is the EGRP®? Parjana® Distribution's innovative technology promotes surface infiltration through installation of Energy-Passive Groundwater Recharge Product (EGRP®) devices. By accelerating infiltration into and through the near surface soils, EGRP® technology increases the volume of stormwater that can be stored, infiltrated and ultimately recharged.  Surface water that would have pooled or run off is captured below grade and filtered, which improves water quality and reduces flooding.  At each project site, a series of EGRP® devices are installed vertically into the ground underneath natural topsoil that allows water to be naturally filtered entering the EGRP®s. The devices can be operated with or without additional stormwater enhancement that can be used to increase volume storage and/or water quality. The many individual channels within the EGRP® arrays serve to initially capture surface water and subsequently dewater upper soils, thereby preparing the upper soil layer for the next wet-weather event
