November 4, 2021 – The end of daylight saving time on Sunday offers residents a reminder to assess their outdoor watering needs and adjust their irrigation systems to reduce water waste – an especially important step after more than two years of statewide drought. Plants simply don’t need as much water during cooler months, and they typically don’t need irrigation at all after heavy rains.
San Diego County Water Authority Operations and Maintenance staff recently completed a complex relining project on a section of Pipeline 3 in central San Diego, within Mission Trails Regional Park. Pipeline 3 traverses the western portion of the region from the Riverside County border in the north to Lower Otay Reservoir in the south.
Large-diameter pipelines operated by the Water Authority and its 24 member agencies extend approximately 310 miles to convey water throughout the region.
By relining pipes ahead of time or conducting timely repairs, the Water Authority and its member agencies avoid pipeline failures and improve the reliability of future water supplies. The proactive Pipeline 3 relining project is part of the asset management program to make preventative repairs to large-scale infrastructure.
In June 2020, O&M staff performed an inspection of Pipelines 3 and 4 within Mission Trails Park during a routine shutdown. They inspected an area of Pipeline 4 that had previously been repaired, and the repairs were found to have held up successfully. Pipeline 3 has similar characteristics to Pipeline 4 in that area, and during the shutdown, staff inspected and found a 32-foot section of pipeline that had sustained lining damage. Between August and September 2021, staff completed the complex repairs on Pipeline 3.
“The project was challenging due to several geographical factors, including the distance of access structures from the damaged section and the steep grade of the hill that the section of pipeline traverses,” said David Hernandez, maintenance technician at the Water Authority. “Our asset management, facility maintenance, and mechanical maintenance teams collaborated closely to plan and execute the complex repairs.”
To begin the relining project, heavy concrete covers at access point structures were first removed to allow staff to access the pipeline. Piping and an air valve at the top and pumping well at the bottom of the hill were then removed to allow for safe access. Staff installed an atmospheric ventilation fan that moved fresh air into the pipeline. Once the piping and valves were removed, they were able to enter the pipeline.
Staff then hiked through the pipeline to perform a visual inspection and locate the damaged area. They located the broken lining section and loaded broken pieces into buckets and manually hauled the buckets to access structures. Then the metal pipeline was prepared for the application of new liner. Preparation of the pipe took several days – it involved carefully cutting out any remaining damaged liner, descaling rust from the metal, and cleaning up and wiping down the metal to prepare for new lining. O&M staff then mixed the new lining material – approximately 4,400 pounds of dry material was mixed and lifted over the course of the project. The new liner was then manually applied to the pipe, starting from the bottom half for traction and then applied up to the crown of the pipe. Finally, every inch of the new lining was carefully inspected.
The highly specialized work effort was performed in a safe and efficient manner due to careful planning and execution by the Water Authority’s O&M staff. Throughout the process, staff took multiple safety measures, including wearing personal protective equipment, having a confined space rescue team on standby, and tying hand and foot loops into a safety rope. The entire project took approximately one month. It will extend the lifetime of Pipeline 3, a crucial component to the region’s water supply.
The San Diego County Water Authority has begun crafting its 2023 Water Facilities Master Plan Update and will advertise for professional service support in early November following an update last week to the Board of Directors. The plan, updated every 10 years, will lay out strategies to optimize Water Authority facilities to serve the region under a range of future conditions through the 2045 planning horizon.
The draft version of the master plan is anticipated to be completed by winter 2023, followed by Board adoption of the final plan in early 2024. The development of the master plan builds on the region’s recently approved 2020 Urban Water Management Plan, which updated water demand projections to 2045.
The Water Authority’s master plan guides future investments, defines strategies to identify facility needs, and focuses on system optimization to ensure the Water Authority can meet future member agency water demands in a reliable and cost-effective way.
“As we move into the next decade of regional water facilities planning, it is important the Water Authority continue to lead regional preparations for an uncertain future by improving existing infrastructure with resiliency and flexibility in the face of climate change,” said Water Authority General Manager Sandra L. Kerl. “Especially in these times of drought, we all realize the full value of water and all that goes into a sound water delivery system to sustain our region’s $253 billion economy and quality of life.”
The previous master plan update in 2013 relied on the 2010 UWMP demand projections and incorporated a new normal of reduced water sale volumes, due to a greater emphasis on local supply development, water use efficiency, and new energy management options. Going forward, the 2023 master plan update will continue to focus on facility optimization; system changes due to local supply development by member agencies (such as potable reuse projects); updated water use efficiency regulations; and climate change.
Preliminary objectives of the 2023 update include:
Staff will lead the development of the master plan with support from a contractor team selected through a request for proposals that’s expected to be issued in November. Key tasks in the scope of work will include:
In addition to the Water Facilities Master Plan, the Water Authority also regularly updates its Urban Water Management Plan, Aqueduct Operating Plan, Long-Range Financing Plan, Climate Action Plan, and several others. Those documents work together to ensure the right mix of supplies and facilities to meet the region’s needs at the right time at an affordable cost.

November 2, 2021 – The San Diego County Water Authority has begun crafting its 2023 Water Facilities Master Plan Update and will advertise for professional service support in early November following an update last week to the Board of Directors. The plan, updated every 10 years, will lay out strategies to optimize Water Authority facilities to serve the region under a range of future conditions through the 2045 planning horizon.
October 28, 2021 – The San Diego County Water Authority today activated Level 1 – Voluntary Conservation of its Water Shortage Contingency Plan in support of Gov. Gavin Newsom’s efforts to sustain California after two record-dry years. The agency’s 36-member Board of Directors voted unanimously to activate the regional drought response plan for the third time this century.
October 28, 2021 – The San Diego County Water Authority’s Board of Directors today announced a plan to distribute $35.9 million to its 24 member agencies across the region after receiving a fund transfer from the Los Angeles-based Metropolitan Water District of Southern California to pay legal damages and interest.
San Diego County residents joined Americans across the country marking Thursday, October 21 as “Imagine A Day Without Water.” The nationwide awareness campaign offered opportunities to learn about our nation’s water systems and the hard work that goes into ensuring a day without water doesn’t become a reality for their community.
The day-long event is sponsored by the U.S. Water Alliance, the only national nonprofit organization with a diverse membership base representing the range of water champions, including water utilities, public officials, the business community, environmental organizations, community leaders, policy organizations, and researchers.
The Vallecitos Water District partnered with the City of San Marcos to promote Thursday’s awareness efforts among its residents. San Marcos Mayor Rebecca Jones starred in a video produced by VWD to highlight its water infrastructure investments. In the video, Mayor Jones encourages residents to conserve water. The San Marcos City Council officially proclaimed October 21, 2021 as “Imagine a Day Without Water.”
California Governor Gavin Newsom extended the state’s drought emergency on October 19, appealing to all Californians to do more to conserve water in the face of one of the state’s most severe droughts on record. The declaration added eight remaining counties, including San Diego County, not under the original declaration made in July.
In the United States, aging infrastructure, intensified weather events, and a lack of investment have kept more than two million residents from accessing safe and reliable water and wastewater services. Member agencies, including the Vallecitos Water District along with the San Diego County Water Authority, continue to develop and maintain safe, reliable water supplies and critical infrastructure through strategic planning, long-term investments, and state-of-the-art technologies.

The El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project has reached its final stage. After the Olivenhain Municipal Water District Board approved filing of a notice of completion for the pipeline portion of the project, the City of Encinitas will finish restoring the street and complete new bike lane striping.
The original pipelines were installed in 1961 and 1974 and fast approaching the end of their lifespan. OMWD replaced approximately 4,700 linear feet of existing 12-inch diameter potable water pipeline along North El Camino Real from Encinitas Boulevard to Garden View Road, and approximately 650 linear feet of existing 12-inch diameter pipeline between Via Molena and Mountain Vista Drive. Water service lines and fire hydrant laterals served by the existing pipelines were also replaced.
The pipeline replacement will reduce water loss and prevent emergency shutdowns due to leaks. This is vitally important for water conservation and to ensure water supply reliability for businesses and residents, more important than ever due to drought conditions in the region.
“Proactive maintenance is a big part of what we do,” said Olivenhain Municipal Water District Board President Larry Watt. “Replacing aging infrastructure before it breaks helps to avoid emergencies, which are more costly and more impactful to customers.”

To mitigate the impact to the surrounding community, OMWD coordinated with the City of Encinitas on its green bike lane project along the same route. The District implemented the lane restriping portion of the project on behalf of the City of Encinitas concurrently with the pipeline replacement project as an efficiency measure.
As a result, the two agencies combined what would normally be two separate, unrelated infrastructure improvement projects into a single effort to improve operational efficiency and reduce the temporary inconvenience of disruptions to area residents and businesses.
The bike lane will provide traffic calming measures, including improvements to safety and mobility for bicyclists along North El Camino Real from Encinitas Boulevard to Leucadia Boulevard by restriping and narrowing travel lanes. In addition, green-colored striping will augment some areas on the bike lanes and new signage and pavement markings will be installed.
“It was very important to us from the outset of the project to mitigate its impacts to the community, while also keeping costs down,” said Watt. “To that end, the partnership with the City of Encinitas was critical. They coordinated closely with us every step of the way.”
At the start of the project, the City of Encinitas requested that work be done at night to further reduce traffic impacts. Capitalizing on the reduced traffic as a result of the statewide stay-at-home order, OMWD was able to shift construction to the daytime for a portion of the project. Working during the day is more efficient and safer than night work, and minimized noise impacts to the surrounding neighbors. However, as traffic returned to normal levels, the City shifted work hours back to overnight.

The final work effort will include buffered bike lanes on the east and west, and fully restoring three lanes of traffic. Work is anticipated to occur through early December. Traffic controls will be in place during the day and at night with the most significant work occurring at night. Residents and businesses should anticipate lane closures and consider alternative transportation routes.

Encinitas, Calif. — In an October 19 proclamation, Governor Newsom extended to Southern California the drought-related State of Emergency that had been declared earlier in the year for other areas of the state. The emergency declaration directed water agencies throughout the state to activate their Water Shortage Contingency Plans to preserve water supplies.
Olivenhain Municipal Water District had already activated Level 1 of its Water Shortage Contingency Plan in 2016. At the Level 1 condition, customers are encouraged to take voluntary actions to reduce water waste, such as promptly fixing leaks, stopping runoff from inefficient irrigation, irrigating only during night and early morning hours, and avoiding washing down paved surfaces.
October 20, 2021 – The San Diego County Water Authority is preparing to activate Level 1 – Voluntary Conservation of its Water Shortage Contingency Plan in support of Gov. Gavin Newsom’s efforts to sustain California after two record-dry years. The agency’s 36-member Board of Directors will decide at its formal monthly meeting on Oct. 28 whether to activate the drought response plan, following today’s recommendation by staff.
