OMWD Recognized for Construction Projects to Ensure Water Reliability

Encinitas, Calif. — Olivenhain Municipal Water District’s Indian Head Canyon Pipeline Restoration Project and El Camino Real Potable Water Pipeline Replacement Project were both recognized today as 2022 Projects of the Year by American Public Works Association’s San Diego and Imperial County Chapter at its awards event in Mission Valley.

“OMWD takes great pride in providing uninterrupted water service to our customers,” said OMWD Board President Larry Watt. “Replacing and repairing infrastructure before it fails helps to avoid emergency repairs, which is a more cost-effective and less impactful approach.”

Major Relining Project Honored by the American Public Works Association

The San Diego and Imperial Counties Chapter of the American Public Works Association recently recognized a San Diego County Water Authority pipeline relining project for its excellence as a public works project. The award commends the successful partnership between Water Authority staff, the contractor and local agencies working together to complete this critical repair to maintain the reliability of the regional water supply.

Relining project covers 12,300 feet

Pipeline 5 was relined from the point of delivery with the Metropolitan Water District of Southern California to Sage Road in the Fallbrook and Rainbow communities in north San Diego County. The $24.7 million project was completed in July 2019 and relined approximately 12,300 feet of Pipeline 5, a 96-inch large-diameter regional pipeline.

30-year pipeline relining program rehabilitates aging pipes

Relining is a cost-effective method to repair pipelines and extend their service life with less impacts to the community and environment than if a traditional pipe replacement is performed. The relining process avoids digging up miles of pipeline, which would take significantly more time and resources, as well as impact associated streets and driveways for a long period of time.

“The Water Authority’s asset management program used an acoustic fiber monitoring system to help perform evaluations of the pipeline and prioritize this portion for rehabilitation,” said Jerry Reed, director of engineering at the Water Authority. “Our staff collaborated with stakeholders in Fallbrook, San Marcos and Rainbow, including staff at our member agencies and nearby residents to ensure project success.”

The project work areas were surrounded by residential homes and farms, heavily traveled public streets and a local retirement community.

Close coordination with multiple agencies ensured there were no impacts to water deliveries. Open communications with local residents regarding project schedule ensured no incidents occurred with local traffic.

Proactive asset management program rehabilitates crucial water infrastructure

The relining project was part of the Water Authority’s proactive and innovative asset management program to rehabilitate and reline pre-stressed concrete cylinder pipe within the Water Authority’s conveyance system to ensure continued supply reliability.

The local APWA chapter chose the project based on criteria that included superb planning, efficient design and construction management techniques to complete the project on schedule, within a cost-effective budget and adherence to regulatory requirements. It was also judged on the degree it enhanced a public service or facility, the quality of community relations or actions to minimize public impacts, safety precautions taken to protect lives and property, environmental impact mitigation measures and other accomplishments under adverse conditions.
