Orange County Water District (OCWD) Groundwater Replenishment System (GWRS) Expansion, Fountain Valley, CA
Orange County Water District (OCWD) Groundwater Replenishment System (GWRS) Expansion, Fountain Valley, CA

Project Description

z•Yourman & Associates (DYA) performed a geotechnical investigation for the expansion of the groundwater replenishment system at OCWD in Fountain Valley, California.  The GWRS consists of three major components: (1) Advanced Water Purification Facility (AWPF) and pumping stations located in Fountain Valley; (2) a 14-mile pipeline adjacent to the Santa Ana River connecting the treatment facilities to existing recharge basins in the cities of Anaheim and Orange; and (3) the expansion of an existing seawater intrusion barrier in the cities of Fountain Valley and Huntington Beach.

The expansion entails the construction of additional treatment facilities at the AWPF site in Fountain Valley and includes adding treatment capacity to the AWPF in Fountain Valley to increase its nominal design capacity from 70 to 100 mgd. Construction is expected to be completed in 2015.
