Orange County Water District Groundwater Replenishment System
On Jan. 10, the Orange County (Calif.) Water District (OCWD)
celebrated the fifth anniversary of its Groundwater Replenishment System.
In the 1990s, OCWD and the Orange
County Sanitation District
(OCSD) joined efforts to develop the GWRS water purification
OCWD needed to increase its groundwater recharge volume to
/d (35 mgd) from 56,800 m
/d (15 mgd) to
prevent seawater intrusion, and OCSD faced the possibility of building a second
ocean outfall to dispose of wastewater effluent.
