The award-winning Hauck Mesa Storage Reservoir enhances drinking water supply reliability and operational efficiency for the region. Construction was completed June 23 on the San Diego County Water Authority project in North San Diego County.
Work started in March 2021 with the demolition of an out-of-service steel tank.
Project work included construction of an underground isolation vault and flow control facility, in addition to a new 2.1 million-gallon water tank connected to the Valley Center Pipeline.

Operational flexibility is increased at Hauck Mesa by balancing the flow of treated water between the agency’s First and Second Aqueducts and by helping to maintain water deliveries if power supplies are interrupted. The new storage reservoir enhances the Water Authority’s ability to provide reliable and efficient deliveries of treated water to member agencies.
The walls of the new tank are about 60 feet tall, stained a forest green color to blend in with the natural landscape, and made of prestressed, or wire wrapped, concrete.
“The prestressed technology will maintain the tank walls in permanent compression, allowing the tank to accommodate seismic events while remaining watertight,” said Water Authority Construction Manager Emma Ward-McNally.
The project reached a major milestone in April 2022 when crews poured the concrete roof of the new prestressed concrete water tank. The entire system, including the new tank and flow control facility, was put into service in May 2023.

The Hauck Mesa Storage Reservoir project has received two awards: The 2023 Honor Award from the American Public Works Association for Utilities in the $6 – $25 million category and was a joint winner of the 2023 Outstanding Water Project from the American Society of Civil Engineers.

Strategic infrastructure improvements by the Water Authority and its member agencies are part of the regional effort to ensure continued delivery of water to support the region’s $268 billion economy and the quality of life for 3.3 million residents. As part of the asset management program, it is critical to actively replace and repair the Water Authority’s assets, which include pipes, valves, facilities, equipment, and other infrastructure.
During construction, the Water Authority worked closely with the Valley Center community, Valley Center Municipal Water District, and nearby homeowners to minimize short-term construction impacts during the project.
The Water Authority operates and maintains a regional water delivery system capable of delivering 900 million gallons of water per day. Building and operating the large-scale infrastructure required to meet the region’s water needs now and in the future requires careful planning and technical expertise. The Water Authority uses a sophisticated approach to cost-effectively build, operate, maintain and secure its water facilities as an integrated system.
(Editor’s note: The Valley Center Municipal Water District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the San Diego County region.)
The San Diego County Water Authority Hauck Mesa Storage Reservoir project in North San Diego County reached a major milestone in late April when crews poured the concrete roof of the new prestressed concrete water tank. The major construction project, which began in March 2021, will improve drinking water supply reliability for the county.
A major construction project to improve drinking water supply reliability in North County will start in February after the San Diego County Water Authority’s Board of Directors January 28 approved an $11.4 million contract for the work to Pacific Hydrotech Corporation of Perris, California.
The Hauck Mesa Storage Reservoir project includes demolition of an abandoned steel tank, building a 2.1 million-gallon storage reservoir connected to the Valley Center Pipeline, and construction of an isolation vault and an underground flow control facility. The project is expected to be completed by winter 2022.

Strategic infrastructure improvements by the Water Authority and its 24 member agencies are part of the regional effort to ensure continued delivery of water to support the region’s $245 billion economy and the quality of life for 3.3 million residents. The Water Authority just completed a $30 million series of upgrades on the historic First Aqueduct in North County to ensure these facilities continue to serve the region for many more decades.
“These upgrades are investments in our future,” said Water Authority Board Chair Gary Croucher. “Ever-changing conditions mean the work is complex and challenging, but continued vigilance helps ensure that we can meet our region’s water needs both today and for decades to come.”
As part of the asset management program, it is critical to actively replace and repair the Water Authority’s assets, which include pipes, valves, facilities, equipment and other infrastructure.
The new Hauck Mesa Storage Reservoir will provide operational flexibility, enhanced system reliability for the day-to-day operations of the aqueduct system, and help ensure water deliveries can be maintained even if power supplies are interrupted.
The Water Authority will continue to work closely with the Valley Center community, Valley Center Municipal Water District, and nearby homeowners to minimize short-term construction impacts.

January 28, 2021 – A major construction project to improve drinking water supply reliability in North County will start in February after the San Diego County Water Authority’s Board of Directors today approved an $11.4 million contract for the work to Pacific Hydrotech Corporation of Perris, Calif.
The San Diego County Water Authority is gearing up to construct a 2.1 million-gallon drinking water reservoir on the Valley Center Pipeline to enhance service reliability throughout the region. The Hauck Mesa Storage Reservoir project in northern San Diego County is part of the Water Authority’s Capital Improvement Program. Construction work is scheduled to begin in early 2021 and is estimated to be completed in the winter of 2022.
