✦ Synopsis
On November 15, 1991, the Orange County Water District (OCWD) was issued the first permit for a research and demonstration groundwater recharge project under the proposed Regulations for Groundwater Recharge with Reclaimed Wastewater being developed by the California Department of Health Services (DHS). The Department approved the injection of 100 percent reclaimed water from OCWD's Water Factory 21 (WF-21) into the Orange County groundwater basin to maintain a seawater barrier and to replenish aquifers used for domestic water supply. The proposal was approved as an ongoing "research and demonstration project", subject to several conditions. The process leading to the approval, the conditions imposed, and how OCWD will comply with those conditions are the main subjects of this presentation. The Need for Water Factory 21 Water Factory 21 was constructed by the Orange County Water District to produce water for injection into the Talbert Gap to form a barrier to seawater intrusion. Historic overproduction from the Orange County groundwater basin created a seawater intrusion problem in the coastal areas of the district. (Figure 1) The problem was most serious in the Talbert Gap, the alluvial filled erosional formation created by the ancient flow patterns of the Santa Ana River between the Newport Mesa and Huntington Mesa. The idea of reclaiming wastewater for injection to create a hydraulic barrier to seawater intrusion in the
