2017 Talbert seawater intrusion Barrier - Distribution Pipeline Upgrades

​JIG is pleased to announce a new project with Orange County Water District (OCWD) for the Talbert Seawater Intrusion Barrier Distribution Pipeline Upgrades. The Talbert Barrier Distribution Pipeline is part of OCWD’s seawater barrier system which prevents seawater from flowing inland in response to freshwater aquifer pumping by coastal cities. The project is for upgrades to the existing Talbert Seawater Intrusion Barrier Distribution Pipeline to alleviate existing restrictions in the system. A hydraulic model will be developed to confirm “bottleneck” areas with high velocities and develop alternatives for alleviating these conditions.
 
Two potential “bottleneck” areas have been identified. The first area is an 800 foot pipe segment near the Ellis Avenue/Ward Street intersection, near the OCWD plant. The second area is a 135 foot pipe segment crossing under the Talbert Channel.
