San Diego County Water Authority crews recently replaced two pickup truck-sized valves at the agency’s Pressure Control and Hydroelectric Facility in central San Diego – each valve weighing about 35,000 pounds. The pressure-control facility is a key piece of the Emergency and Carryover Storage Project, which ensures water is available around the region if imported water deliveries are disrupted.
The U.S. Bureau of Reclamation has awarded three San Diego County water agencies a total of $2,788,500 in 2021 WaterSMART Water and Energy Efficiency Grants. A total of $42.4 million in grants was given to 55 projects across 13 states to improve water reliability and efficiency, conserving more 98,000 acre-feet of water per year.

“The Water Authority and its member agencies have been leaders in helping customers improve water efficiency, which ultimately helps our communities become more resilient to both dry years and the large-scale impacts of climate change,” said Water Authority Board Chair Gary Croucher. “This grant money is added value for our region as we continue to do our part for people and the planet.”
The Bureau of Reclamation grants support the new Executive Order on Tackling the Climate Crisis at Home and Abroad to increase resilience to climate change impacts. The agency’s WaterSMART program works cooperatively with states, tribes, and local entities to plan and implement actions that increase water supply reliability through investments to modernize existing infrastructure and attention to local water conflicts.

San Diego County Water Authority crews recently replaced two pickup truck-sized valves at the agency’s Pressure Control and Hydroelectric Facility in central San Diego – each valve weighing about 35,000 pounds.
The replacement project took place during a scheduled shutdown of a portion of Pipeline 5, which delivers untreated water throughout the county. The pressure-control facility is a key piece of the Emergency and Carryover Storage Project, which ensures water is available around the region if imported water deliveries are disrupted.
Several large-diameter valves in the facility control the pressure and quantity of water delivered to reservoirs and water treatment plants in eastern and southern parts of the county. In addition, a hydroelectric turbine in the facility generates supplemental electricity that reduces the Water Authority’s energy costs while supplying surplus power to the region.
“The new valves will allow the facility to function efficiently at both low and high water flows, depending on regional demand,” said Kirk Whitaker, a senior engineer at the Water Authority. “The project is part of ongoing improvements that enhance the flexibility of our regional water delivery system.”
To perform the valve replacement, a large crane lifted the existing valves out of the facility through the roof and placed them onto flatbed trucks for delivery to a disposal and recycling site. The new valves were then lowered into the facility through the roof and fitted with new 42-inch pipeline sections. Concrete was poured to build pedestals that secure the valves in place.
The new valves were produced in Germany and transported to San Diego by ship. The valve installation process took four days to complete.
The Pressure Control and Hydroelectric Facility serves an important function in improving aqueduct operations and enhancing the flexibility of the Water Authority’s extensive water delivery system. The $21 million facility was completed in 2007 and pressurizes a 22-mile-long section of the Water Authority’s large-diameter Pipeline 5 between San Marcos and Mira Mesa.
The pipeline previously conveyed water in one direction only, from north to south, by gravity. This limited the Water Authority’s ability to move water around the county in the event of a supply disruption. Upgrades to Pipeline 5 now allow water to be transported either north or south using water stored at San Vicente Reservoir, which greatly improves pipeline operations and ensures that water can continue flowing to member agencies.

Helix Water District will use $2.8 million received from the San Diego County Water Authority as part of a legal settlement with the Metropolitan Water District of Southern California to reduce future water rates for the district’s customers.
Padre Dam Municipal Water District’s Board of Directors has unanimously approved using the recently received $1,157,552 rebate from the San Diego County Water Authority to offset the District’s next pass-through rate increase from the CWA. This action will result in a direct benefit to customers by the reduction or potential elimination of a water pass through rate hike in 2022.
Poway is gearing up for several years of water infrastructure improvement projects, including replacing the city’s aging clearwell.
The Poway City Council received an update at its Tuesday night meeting on the Water Infrastructure Improvement Program, which includes three projects spanning the next four-to-five years.
The program includes bypassing and then replacing the clearwell with two new storage tanks. Poway’s clearwell, which was built in 1964, is used to store treated water from the city’s Lester J. Berglund Water Treatment Plant before distribution.
The other project in the program is creating a treated water connection to the San Diego County Water Authority. Poway has a raw water connection to the SDCWA and treats its own water, but a treated water connection will build redundancy in the system, said Shadi Sami, principal civil engineer.
March 17, 2021, Santee, Calif. – Padre Dam Municipal Water District’s Board of Directors unanimously approved using the recently received $1,157,552 rebate from the San Diego County Water Authority to offset the District’s next pass‐through rate increase from the San Diego County Water Authority. This action will result in a direct benefit to customers by the reduction or potential elimination of a water pass through increase in 2022.
