When looking from the right vantage point towards Mission Trails Regional Park, a brown hill can be seen. This is the San Diego County Water Authority’s Mission Trails Flow Regulatory Structure II Project, or FRS II, under construction. Once complete, the dirt hill will be leveled to its previous contours and revegetated with native plants – many seeded from plants within the park itself.
An underground reservoir is being constructed within the park to improve the Water Authority’s untreated water system in the northwest area of the park. The upgrade will increase reliable water delivery to treatment plants that serve the central and south sections of San Diego County.

Work efforts on the new FRS II are beginning to take shape with many of the wall sections installed.
The FRS II will be an underground concrete water tank that will store slightly less than five million gallons of water and be used to balance flows in the aqueduct system. FRS II will be the second underground water tank in the park – both work to efficiently move water through the region. Construction is also underway on a new flow control facility, which is part of the project.

Residents are kept up to date on construction impacts to streets and other infrastructure through several outreach efforts including an interactive construction map, detailed online schedule, regular newsletters, and virtual open house presentations live on the City of Oceanside’s YouTube channel, offering residents the opportunity to ask questions.
“We understand living and commuting near a construction site is not easy,” said Cari Dale, water utilities director for the City of Oceanside. “Everyone involved with the project is thankful to those residents and business owners who live and work in the construction zone for their patience and cooperation. It is crucial to the successful on-time completion of this vital infrastructure project.”

Pipeline installation is now taking place at North River Road and the Douglas Drive intersection, and moving towards Pala. Lane closures on Douglas Drive allow access to the businesses through the entrance on North River Road.
In addition, pipeline installation on Pala Road is now underway. The road will remain open both ways but will require lane closures.
Well construction, which includes injection and monitoring wells, requires closing a section of Coco Palms Drive (south of Cherrystone Street), which will reduce construction time and impacts to nearby residents. Well drilling will continue 24 hours a day, seven days a week for approximately three weeks until early 2021. During this time, 16-foot sound walls have been installed around the drilling site to direct sound waves up into the atmosphere and away from residents. Night construction lighting will also be mitigated by the sound walls.
After drilling is complete, additional work will be conducted for testing and to install well infrastructure. The post-drilling work will take place weekdays during business hours and occasional Saturdays.

The Claude “Bud” Lewis Carlsbad Desalination Plant is celebrating its fifth year of operation this month. More than 65 billion gallons of water from the plant have provided a sustainable and reliable supply to businesses and residents of San Diego County since December 2015.
The Carlsbad Desalination Plant produces more than 50 million gallons of high-quality, locally controlled, water every day. It’s a foundational water supply for the San Diego region that minimizes the region’s vulnerability to drought or other water supply emergencies.
“The desalination plant is a key piece of the region’s multi-decade strategy to diversify our water supply portfolio,” said Sandra L. Kerl, general manager of the San Diego County Water Authority. “As we celebrate five years of operation, the plant continues to provide a drought-proof supply that reduces our dependence on imported water sources vulnerable to droughts, natural disasters, and regulatory restrictions.”
A 30-year Water Purchase Agreement between Poseidon Water and the Water Authority allows for the production of up to 56,000 acre-feet of water per year, enough to meet the needs of approximately 400,000 people. The facility is the largest, most technologically advanced and energy-efficient desalination plant in the nation.
“The Carlsbad Desalination Plant was once merely an ambitious vision. Fast forward to today, and we are celebrating the plant’s fifth anniversary of operations, during which we have successfully produced enough water to meet the needs of San Diego County residents,” said Carlos Riva, CEO of Poseidon Water. “This is an incredible accomplishment and an example of how communities throughout California can invest in the state’s future water security.”

Desalination uses reverse osmosis technology to remove water molecules from seawater. Water from the ocean is forced through tightly-wrapped, semipermeable membranes under very high pressure. The membranes allow the smaller water molecules to pass through, leaving salt and other impurities to be discharged from the facility.
Reverse osmosis is the heart of the Carlsbad plant. During this process, dissolved salt and other minerals are separated from the water, making it fit for consumption. This reverse osmosis building contains more than 2,000 pressure vessels housing more than 16,000 reverse osmosis membranes. Photo: San Diego County Water Authority
Three new fish-friendly seawater intake pumps, commissioned in July 2020 at the Claude “Bud” Lewis Carlsbad Desalination Plant, are among the most environmentally advanced intake pumps in the world. The pumps are part of a broader effort to ensure the long-term health of the marine environment near the Plant, which sits on the shores of Agua Hedionda Lagoon. Photo: San Diego County Water Authority
Installation of the new intake pumps is part of a phased program to replace the existing seawater intake and discharge facilities with state-of-the-art technology to protect marine life. The technology wasn’t available when the plant was operating with source water from the Encina Power Station.
The next steps include adding new intake screens, designed to prevent any sea-life larger than 1 millimeter (thicker than a credit card) from entering the plant. The new intake screens are the final part of upgrades, which when complete in 2023, will make the Carlsbad Desalination Plant the first desalination facility in California to comply with the 2015 California Ocean Plan Amendment, among the most advanced sea-life protection measures.
Desalination plant project partners Poseidon Water and the San Diego County Water Authority celebrated delivering 40 billion gallons of drought-resilient drinking water to San Diego County during three years of commercial operations at the plant.

Operations are under way at the nation’s largest and most technologically advanced seawater desalination plant, which was dedicated today by more than 600 elected officials, community leaders and project partners. After successfully completing construction, the Claude “Bud” Lewis Carlsbad Desalination Plant has already produced more than 1.5 billion gallons of locally controlled water for San Diego County, helping to minimize the region’s vulnerability to the statewide drought.
The Carlsbad Desalination Project included 1.5 million hours of work in Carlsbad, Vista and San Marcos, supporting an estimated 2,500 jobs and infusing $350 million into the local economy. Project partners included the Water Authority, Poseidon Water, IDE Technologies, Stonepeak Infrastructure Partners and Kiewit-Shea Desalination. Photo: San Diego County Water Authority

For 60 years, Miramar Reservoir has been an integral part of the City of San Diego’s drinking water system and offers San Diegans a popular recreational area. Now, the reservoir is being called into service to play a vital part in San Diego’s future Pure Water system to sustain a reliable water supply.
The City of San Diego is commemorating the 60th anniversary of Miramar Reservoir, its role in the region’s history, and the part the reservoir will play in the future.
“We celebrate not only Miramar Reservoir’s past, but the critical role it will play when the Pure Water system is completed,” said Shauna Lorance, director of the San Diego Public Utilities Department. “Miramar Reservoir will continue to be a key part of our water system for many years to come.”

Miramar was the last of the City’s nine reservoirs to be developed. It was completed in 1960 as part of the second San Diego Aqueduct. The location previously had been the site of a small reservoir serving the vast ranch of newspaper publisher Edward W. Scripps.
Water flowing south to the reservoir originates from both the Colorado River Aqueduct and the California Aqueduct. The earthen embankment dam has a maximum height of 165 feet measured from the downstream toe, and has a base of 1,180 feet.

It was constructed by contractors Einer Brothers Inc. of Escondido and McCammon Construction, for $1.42 million. Land acquisition and engineering costs were approximately $730,000. Funds for the project came from an $11 million water bond approved by San Diego voters in June 1958.
When full, the reservoir covers 274 surface acres, reaches a maximum water depth of 114 feet, and has four miles of shoreline. Miramar Reservoir has a water storage capacity of 6,682 acre-feet.
Miramar Water Treatment Plant, which was completed in 1962 at a cost of $3.5 million, and expanded and upgraded in 2010, treats and filters drinking water distributed to customers in the northern part of San Diego.
Since the mid-1960s, the reservoir has been a popular recreational destination. An estimated 100,000 people visit Miramar each year to enjoy jogging, walking, biking, fishing, boating, picnicking, among other activities.

When the Pure Water system comes online, Miramar Reservoir will switch from holding imported water to holding purified water received through a pipeline from the planned North City Pure Water Facility. After water has been purified at the North City Pure Water Facility, it will then be transferred via pipeline to Miramar Reservoir. The Miramar Water Treatment Plant will clean the water again, and the water will be distributed to homes and businesses throughout northern San Diego.
Miramar Reservoir will continue use into the foreseeable future as it helps provide one-third of San Diego’s water supply locally by the end of 2035.
