Manchester Pipeline Projects Begin with Replacement of Potable Water Pipeline

This is the first of two pipeline projects beginning in 2021 that will occur in the Manchester Avenue corridor

Olivenhain Municipal Water District is beginning construction this week to replace aging water infrastructure near the intersection of Rancho Santa Fe Road and Encinitas Boulevard.

OMWD takes a proactive approach in repairing and replacing aging water infrastructure. These proactive measures help prevent disruptive and costly main breaks to ensure continued water service to customers. The pipelines that will be replaced are approaching the end of their lifespan. The pipelines were originally installed in 1961.

“Water main breaks can waste millions of gallons of treated water while requiring costly emergency repairs,” said OMWD Board Secretary Bob Topolovac. “That is why this project is critical in ensuring safe and reliable water delivery to our customers.”

Further, installing the new pipeline will reduce water loss and avoid leaks. As the impact of California’s drought continues to escalate, projects like this that help save potable water are even more urgent.

The project will at times take place during the day. However, the majority of the project will be completed at night, per the City of Encinitas, between 9:00 p.m. to 6:00 a.m. in order to diminish traffic disruptions. The project has been designed to minimize noise and traffic impacts to the public, but delays are possible. The project is currently on track to be completed by the end of the year.

The other major portion of the Manchester Pipeline Projects will expand recycled water service to the corridor along Manchester Avenue and South El Camino Real, which is expected to begin in late 2021.
