FRS II: Mission Trails Water Project Takes Shape
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.

FRS II will help balance regional water flows
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.

Pure Water Oceanside Installing New Pipelines and Drilling Wells
Pure Water Oceanside is installing new pipelines and drilling wells as the recycled water project continues on track for completion in 2022. The advanced water purification project, and expansion of the City of Oceanside’s existing recycled water system, will deliver a new, local source of high-quality drinking water supplying more than 30% of the city’s water supply when completed.

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 construction

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.
River Bike Trail remains open

Construction for the entire project is expected to be complete in 2022. While most construction will take place during regular weekday business hours, some critical pipeline construction elements will require temporary extended work hours and occasional Saturdays to complete the project on time.
Residents can sign up for email updates about the project. In the event of any immediate concerns, residents can call 760-435-4570 and representatives will troubleshoot issues.
Carlsbad Desalination Plant Celebrates 5th Anniversary
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.
Desalination plant diversifies region’s water supply sources
“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.
Carlsbad Desalination Plant celebrates water supply accomplishment
“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.”
The Carlsbad plant uses reverse osmosis to produce approximately 10% of the region’s water supply; it is a core supply regardless of weather conditions, and it is blended with water from other sources for regional distribution. Photo: San Diego County Water Authority
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
Milestones
July 22, 2020: New Seawater Intake Pumps Preserve Marine Environment
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.
December 13, 2018: Carlsbad Desalination Plant Celebrates 40 Billion Gallons Served
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.
“It’s incredible what we’ve accomplished in three years,” said Sandra L. Kerl, at the 2018 celebration event, general manager of the Water Authority. “Since coming online in 2015, the Carlsbad Desalination Plant has met nearly 10 percent of the region’s water demand, and it will be a core water resource for decades to come.”

Miramar Reservoir Marks 60 Years of Service
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.”
Role in San Diego’s history

Miramar Reservoir marks 60
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.
Miramar Reservoir to become part of Pure Water San Diego

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.
Sen. Atkins to Share Legislative Vision with Water Authority Board
Editors Note: Due to the volume of activity associated with this week’s organizational activities related to the beginning of the 2021-2022 state legislative session, Senator Atkins regretfully had to cancel her appearance during this Thursday’s special Board of Directors meeting, and she expressed her apologies for the unavoidable circumstances and workload that resulted in the cancellation. Fortunately, the Water Authority is honored that state Senator Brian Jones will join the special Board meeting at 2 p.m. Thursday and offer his perspectives on 2020 and his insights on policy and fiscal issues facing California and San Diego County as we advance toward 2021.
California Senate President pro Tem Toni Atkins will share her legislative vision and 2021 policy outlook at a special San Diego County Water Authority Board of Directors meeting on Thursday, December 10. The webcast of the meeting can be viewed at 2 p.m. here.
“I’m hopeful that we’ll hear from Senator Atkins about energy and infrastructure funding and partnership opportunities,” said Sandra L. Kerl, General Manager of the Water Authority. “This has long been one of the top legislative priorities for water and wastewater agencies – and the pandemic has highlighted the need for continued investments in these projects that produce jobs as well as generational benefits.”
Atkins has represented the region since 2000, serving on the San Diego City Council for eight years and in the state Assembly for six years. She was elected to the state Senate in 2016, where she represents the 39th district. The district includes most of the city of San Diego, and Coronado, Del Mar, and Solana Beach. She was elected Senate President pro Tem by her senate colleagues in March 2018.
A champion for California water policy
Throughout her years of public service in state and local government, Atkins has championed sound water policy. She is currently in the middle of coronavirus pandemic-related public safety and economic recovery issues. Atkins received the 2019 Safe Drinking Water Champion Award in January 2020 from the California Municipal Utilities Association in Sacramento.
As leader of the Senate, Atkins was instrumental in bringing California together to find consensus that resulted in passage of the Safe and Affordable Drinking Water Fund of 2019. The long-term funding solution avoided a proposed water tax, ensures safe drinking water for an estimated one-million Californians, and will fix failing water systems in vulnerable communities.
Legislative partnerships are essential for a prosperous future
The San Diego County Water Authority is pursuing partnerships with state and national agencies to advance shovel-ready water and energy infrastructure projects that can help California’s economic recovery gain traction.
Over the years, the Water Authority has hosted numerous legislative roundtable events to promote collaboration with civic, business, and elected leaders to ensure continued water supply reliability for the region.
Past speakers have included Congressmen Scott Peters and Mike Levin, State Assemblymembers Lorena Gonzalez and Marie Waldron, and State Senators Ben Hueso and Brian Jones. Atkins participated in the Water Authority’s Legislative Roundtable in October 2015.
