Document Description
Eastern Municipal Water District's Pala Lift Station pumps raw sewage removal three miles through parallel 18-inch and 20-inch sewage forcemains, from south Temecula to the Temecula Valley Regional Water Reclamation Facility (TVRWRF). The parallel pipelines have twenty-two air release/vacuum valves at eleven locations. These valves are critical components designed to reduce hydraulic surges and prevent damage to pipelines. The air release/vacuum valves may malfunction by sticking open or closed when debris from sewage gets caught in the seats or mechanisms of the valve. Implementing the proposed project will ensure the system functions properly and prevent releases.
