The Valley Center Municipal Water District has been advised by its wholesale supplier, the San Diego County Water Authority, of the following aqueduct shutdown. The shutdown of the San Diego Aqueduct that delivers water to the District will be out of service for rehabilitation repairs and will begin at 1 a.m. on Sunday, February 26, through 8 p.m. on Wednesday, March 8.
More than $63 million in proposed federal funding was announced Tuesday to support nearly two dozen projects across the San Diego region.
Sen. Alex Padilla, D-California, said in a statement that the Fiscal Year 2023 appropriations package that will deliver funding for 22 projects slated for the San Diego region will head next to both chambers of Congress for final passage.
Among the projects expected to receive funding in the package are:
— $3.45 million for the City of Oceanside‘s Loma Alta Creek Sewer Relocation, which will move a sewer main from a creek bed to a roadway to minimize environmental damage in the event of a sanitary sewer overflow.
— $3.45 million for the Smuggler’s Gulch Dredging Project, which will clear trash and sediment to protect downstream communities, and protect human and environmental health in the Tijuana River Watershed and coastal waters.
— $3.39 million for Borrego Water District‘s Borrego Spring Transmission Main, which will update the water distribution system and reduce water pipeline breaks.
— $3.06 million for the Valley Center Municipal Water District‘s Lilac Road Pipeline Replacement, which is aimed at reducing water loss and improving water conservation, among other benefits of the 60-year-old pipeline’s replacement.
Valley Center Municipal Water District and its customers are long accustomed to dealing with periodic aqueduct shutdowns which allow the district’s sole wholesale water supplier, the San Diego County Water Authority, to inspect, repair, and make improvements to our imported water aqueduct system.
However, this coming winter will be especially challenging, as there will be three consecutive aqueduct shutdowns in fairly rapid succession: (1) December 4 –14, 2022, (2) January 22 – February 1, 2023, and (3) February 26 – March 8, 2023.
At play is the fact that the three tunnels on the 1st San Diego Aqueduct (“1st Aqueduct”) need to be relined to protect the quality of the treated water traveling north to south through the enclosed aqueduct, and restore its operational integrity. The 1st Aqueduct serves five of VCMWD’s seven Aqueduct Connections, spanning the full length of the District’s 100-square-mile service area. Although VCMWD does have a connection to the 2nd San Diego Aqueduct (“2nd Aqueduct”), the 1st Aqueduct provides water to approximately 85% of the District’s service area. Completed in the early 1950s, the 1st Aqueduct began serving the fledgling Valley Center Municipal Water District soon after its formation election in 1954 and has served the district continuously for 67 years.
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.
The project began with the demolition of an abandoned steel tank, and includes construction of an isolation vault and an underground flow control facility, in addition to the new 2.1 million-gallon water tank connected to the Valley Center Pipeline. The project is expected to be completed by November 2022.
The new Hauck Mesa Storage Reservoir will increase operational flexibility by balancing the flow of treated water between the agency’s first and second aqueducts as well as ensure water deliveries can be maintained even if power supplies are interrupted.
The walls of the new tank are about 60 feet tall, will be stained a forest green color to blend in with the natural landscape, and are made of prestressed, or wire wrapped, concrete. Construction Manager Emma Ward-McNally said that the prestressed technology “will maintain the tank walls in permanent compression, allowing the tank to accommodate seismic events while remaining watertight.”
Next steps for the project include the wire wrapping of the water tank, applying green-tinted shotcrete to the tank walls, installation of mechanical components within the flow control facility, system commissioning, and paving of the project site and access road.
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 $240 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.
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.
Local students floated lots of good ideas in the 30th annual Water Awareness Poster Contest, sponsored by North County’s water agencies. This year’s theme was “Love Water, Save Water.”
The contest for fourth-graders aims to increase understanding and appreciation for conserving water and using it more efficiently. Students showed ways they love water, how they save water at home, or ways to save or recycle water in the future to help the Earth. Winning students artwork is printed in the 2022 North County Water Agency Calendar. Free copies are available at local water district offices, usually by mid-November.
A major construction project to improve drinking water supply reliability in North San Diego 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 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.

How should power over water decisions in San Diego be divided?
Should the city of San Diego, which represents almost 40 percent of the region’s water consumers, have the most sway?
Or should smaller cities be on equal footing when the outcome of a decision could harm towns with less people and money?
That is the question facing San Diego County Water Authority once again, after the latest vote over a $5 billion duplicate pipeline to the Colorado River. Directors voted down spending $1.7 million more to study the project further, in raw numbers. Twenty of the agency’s 36 directors said no to the pipeline, and 14 said yes.
