Vallecitos Water District-Interceptor-Pipeline-infrastructure

San Marcos Interceptor Project Ready for Phase 2 Summer Start 

/in , /by

The San Marcos Interceptor Replacement Project remains on schedule, with Phases 1 and 1A completed according to the Vallecitos Water District. The project replaces the District’s 1960s era 21-inch diameter sewer interceptor with more than 12,000-feet of 42-inch diameter sewer pipeline between Twin Oaks Valley Road and Pacific Street.

The Interceptor is a large trunk sewer pipeline receiving and conveying wastewater by gravity to the Encina Wastewater Authority. In Phases 1 and 1A of the project between 2002 and 2014, portions behind the Creekside Marketplace from State Route 78 to Grand Avenue, from Twin Oaks Valley Road to east of Johnston Lane, from Grand Avenue to Via Vera Cruz, and east of Johnson Lane to the south side of State Route 78 were completed.

Phase 2 will complete the remaining 3,400-feet of the westernmost project corridor extending from Via Vera Cruz to Pacific Street. The project budget is $8.5 million. The completion of Phase 2 of the Interceptor project has been in the works for more than 30 years, with the project exchanging numerous hands in planning, design, and construction.

“This is a milestone project for the District both in size and significance,” said Ryan Morgan, capital facilities senior engineer.

State of the art construction technology

The project used state-of-the-art trenchless technology to install a 115-ft long tunnel under an existing concrete culvert under the Pacific Street and San Marcos Boulevard intersection. The 42-inch diameter fiberglass reinforced plastic Interceptor sewer was installed inside a 60-inch diameter steel casing pipe.

Using a process known as “microtunneling,” contractor TC Construction and sub-consultant JW Fowler used a MicroTunnel Boring Machine (MTBM) inside an excavation in the eastbound lanes of San Marcos Boulevard and be received in a smaller excavation in the westbound lanes of San Marcos Boulevard at Pacific Street.

The MTBM is larger than 60-inches in diameter to be large enough to bore through native soils, rock, and backfill along the Interceptor alignment. The new tunnel’s wall is pressurized internally using hydraulic fluids before the steel casing is permanently installed. The MTBM is remote-controlled by an operator on the surface and is laser-guided to ensure it stays within the designed horizontal and vertical alignment (line and grade).

The MTBM’s high level of accuracy makes it especially useful when a project needs to avoid conflicts with existing underground utility lines, including a 16-inch diameter high-pressure San Diego Gas & Electric gas line in this project. The microtunnel installation was a 24-hour, 7-day-a-week process.

The microtunnel allowed the District to “thread the needle,” and the tunnel was completed in under a week (plus setup). There was no damage to any of the existing utilities in San Marcos Boulevard, and traffic impacts were minimized.

Project completion nearing this summer

The Interceptor project required biological monitors and archeological monitors for work adjacent to San Marcos Creek or predetermined environmental sensitive areas. Special mitigation measures and biological monitoring were required for construction during bird nesting season between February 15 and September 15. Additionally, tribal paleological monitors from Native American tribes of significance in the area were represented during excavation work in the creek.

The final leg of the project will begin in the easements adjacent to the creek between Via Vera Cruz and McMahr. Construction completion is expected in June 2021.

This replacement project was originally identified in the District’s 1991 Master Plan and has been phased to be completed prior to City of San Marcos development of the Creek District.

Budget-Rates-San Diego County Water Authority-building

Water Authority Recommends 0% Change in Next Two-Year Budget

/in , /by

The San Diego County Water Authority’s general manager today recommended to the Board of Directors a $1.7 billion budget for fiscal years 2022 and 2023 – a 0% change from the current two-year budget – due to the agency’s continuing commitment to cost control.

Water Authority staff also proposed increasing rates and charges for member agencies by 3.6% for treated water and 3.3% for untreated water in calendar year 2022, attributable to more rate increases by the Water Authority’s wholesaler, continued payments for past investments in supply reliability, and inflationary pressures on energy, chemicals, and construction materials.

Although the Water Authority’s budget spans two fiscal years, the agency sets rates annually to manage changing conditions more effectively. The Water Authority Board is expected to vote on rates for next year and the two-year budget at its regular meeting on June 24, following budget workshops on June 8 and 10.

“Major accomplishment”

“Proposing a flat budget is a major accomplishment made possible by strategic guidance from the Board of Directors, input from our member agencies, and the dedication of agency staff who are committed to resilient operations, forward-thinking plans, and regional collaboration,” said Water Authority General Manager Sandra L. Kerl. “The pandemic and economic recession, combined with a second consecutive dry year, created unprecedented challenges, yet we have contained costs while continuing to deliver enough water to sustain our region’s $253 billion economy and quality of life.”

As usual, more than 90% of the Water Authority’s recommended budget is for buying and treating water or building and financing infrastructure. This reflects the Water Authority’s long-term strategy to invest in supply reliability to meet current and future needs of the San Diego region – a strategy that is paying significant dividends during the current drought hitting most of California.

Seven percent of the budget funds the Water Authority’s operating departments. The recommended budget proposes increasing spending by those departments by 1%, or $1.1 million, compared to the current two-year budget.

Key initiatives the Water Authority plans to pursue during the next two-year budget cycle include:

  • Long-term planning – The Water Authority’s Long-Range Financing Plan and the Water Facilities Master Plan will be prioritized. Both are critical documents for projecting the Water Authority’s financial future and providing the Board with flexibility. Phase B of the Regional Conveyance System Study will conclude, and the Board will determine whether to proceed. Another focus is developing water storage capacity in Lake Mead to provide additional drought resilience for San Diego County and other parts of the Colorado River Basin.
  • Controlling costs – The recommended budget includes the elimination of eight staff positions, along with a reduction in outside services and minimizing travel. In addition, equipment replacement was evaluated for deferrals, minimizing the budget impact of day-to-day operations. As always, the budget is partly the function of water sales and water rates, which are both trending upward.
  • Capital improvements – The Water Authority’s Capital Improvement Program is the cornerstone of the agency’s efforts to ensure that regional water delivery and treatment systems continue to meet a variety of ever-changing demands. The agency will move forward on the highest-priority asset management projects, along with detailed seismic, hydraulic and cavitation analysis. Staff also will continue to enhance security systems for physical and cyber assets – a responsibility that grows as potential threats continue to expand.
  • Collaborating with member agencies – Water Authority staff in every department work closely with member agencies to support local efforts, from outreach and advocacy to budget and rate development – and those efforts will continue to be a priority. There are opportunities for collaboration both in joint projects and joint policy issues, such as advocating for local decision-making about drought investments and responses.
  • Communicating with stakeholders – Whether it be in the state Capitol or local chambers of commerce, the Water Authority will continue to share the region’s water story through a full range of engagement tools and creative tactics.

To support the recommended budget, the Water Authority developed its 2022 rate proposal in conjunction with an independent cost-of-service study to ensure rates and charges comply with state law, legal requirements, cost-of-service standards, and Board policies. The Water Authority also worked closely with its member agencies to keep the proposed rates and charges at the low end of earlier projections.

In 2022, the Water Authority proposes charging its 24 member agencies an all-in rate of $1,523 per acre-foot for untreated water, or $49 more per acre-foot than they currently pay. Charges would be $1,833 per acre-foot for treated water, or $64 more per acre-foot than in 2021. (Note: An acre-foot is about 325,900 gallons, enough to serve the annual needs of 2.5 typical four-person households in San Diego County.)

Actual figures will vary by member agency, and each member agency will incorporate costs from the Water Authority into the retail rates it charges to residents, businesses, and institutions.

Prudent financial planning

The Water Authority’s overall rate increase is driven by multiple factors, including rising costs from its wholesale water provider, the Metropolitan Water District of Southern California (up 3.9%), which increased its rates and charges, including the amount it charges to transport the Water Authority’s independent Colorado River supplies.

“Thanks to prudent financial planning and debt management, we are able to keep the proposed rates at the low end of our projections,” said Water Authority Finance Director Lisa Marie Harris. “We’ve worked hard to control rates while maintaining a complex water production, treatment and delivery system that will continue to support the region for generations.”

The rate proposal for Calendar Year 2022 includes strategic withdrawals from the Rate Stabilization Fund. To reduce 2022 rate increases by approximately $65 per acre-foot, the Water Authority plans to draw $25 million from the agency’s Rate Stabilization Fund. The fund was created in 1990 to help avoid rate spikes, especially those driven by reduced water sales. The rate proposal also includes strategic management of the Water Authority debt portfolio resulting in $130 million in net present value savings from several refundings.

The 2022 rate proposal ensures debt-coverage ratios that maintain the Water Authority’s strong credit ratings and minimize the cost of borrowing money for construction projects, an approach that saves ratepayers money over the long run. The Water Authority has senior lien credit ratings of AAA from Standard & Poor’s, AA+ from Fitch ratings and Aa2 from Moody’s.

Pure Water Oceanside-New Virtual Video-Oceanside

Pure Water Oceanside’s New Virtual Reality Video

/in , /by

To celebrate Water Awareness Month in May and highlight the value of water, the City of Oceanside has unveiled its new virtual reality video tour. The 360-degree video shows the water recycling process that prepares water for Pure Water Oceanside. The advanced water purification project will create a new local source of high-quality drinking water that is clean, safe, drought-proof and environmentally sound.

The video provides an immersive 360-degree look at Oceanside’s San Luis Rey Water Reclamation Facility in anticipation of opening the first advanced purified water project in San Diego County. The water for the project will be sourced from the reclamation facility. The virtual 360-degree video allows viewers to engage and look all around by simply using a computer mouse or touch screen or moving their phones in order to see all around.

Virtual reality video is “educational resource”

Viewers who have a virtual headset for cell phones can take it one step further by “stepping into” the video much like a simulation. In June, the City of Oceanside will begin scheduling opportunities for schools and scouts to view the video using city-provided virtual reality goggles.

“As we enter into another dry summer, Water Awareness Month provides a reason to reflect on how valuable Oceanside’s investments in water supply reliability and water use efficiency are,” said Cari Dale, City of Oceanside water utilities director. “The 360-degree video is an educational video resource for the community to have a better understanding of the City’s efforts to create local sources of water including recycled and advanced purified water, which will provide up to 50% of the City’s water supply.

“Pure Water Oceanside and recycled water expansion projects are examples of how the City works efficiently to provide safe, local and sustainable water resources while keeping water rates among the lowest in the county for our residents and businesses,” she added.

Water recycling and reuse projects

Pure Water Oceanside is one of several potable water reuse or recycling projects under development in the San Diego region.

The East County Advanced Water Purification project is a collaborative partnership between the Padre Dam Municipal Water District, County of San Diego, City of El Cajon and the Helix Water District. Once operational, the East County AWP will provide up to 30% of East San Diego County’s drinking water demands, or almost 13,000 acre-feet of water per year, while eliminating the discharge of 15 million gallons of partially treated wastewater into the Pacific Ocean.

Pure Water San Diego is a $5 billion project designed to generate 83 million gallons of water per day by 2035, nearly 50% of the City of San Diego’s water demand based on the new 2021 urban water management plan.

Drought safe and sustainable supply

The combination of Pure Water Oceanside with the City’s recycled water expansion project exemplifies the value the City of Oceanside places on water. The project will safeguard against drought, provide a local and sustainable source of water, and reduce the city’s dependence on increasingly expensive imported water from the Sacramento Bay Delta and the Colorado River.

Scheduled to be completed in 2022, Pure Water Oceanside will be the first operating advanced water purification facility in San Diego County. The $71 million project will use advanced technology to replicate and accelerate the natural recycling process to provide 3 to 5 million gallons per day to the City of Oceanside.

(Editor’s note: The City of Oceanside is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)

Value of Water-Mission Trails-FRSII-Underground reservoir

Value of Water: Mission Trails FRS II

/in , /by

What does project do?

The Mission Trails Flow Regulatory Structure II Project, or FRS II, will be an underground concrete water tank in Mission Trails Regional Park 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 underway and expected to be completed in 2022.

Why is this project important?

Improving the region’s water infrastructure ensures that San Diego County residents are getting a clean, safe, and reliable supply. The FRS II project is another example of the successful long-term strategy by the Water Authority and its 24 member agencies to diversify its water resources, make major upgrades in the regional water delivery and storage system, and improve water-use efficiency.

How do water ratepayers benefit?

The 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.

In 2013, the Water Authority finalized the Regional Water Facilities Optimization and Master Plan Update, the agency’s roadmap for infrastructure investments through 2035. This updated plan focuses on optimizing the Water Authority’s existing infrastructure while maintaining the flexibility to adjust to a range of future water supply needs.

Notable

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. The reservoir will be completely underground – out of sight – but within the control of the San Diego County Water Authority.

Quotable

“The San Diego County Water Authority is building a massive 5-million-gallon concrete water storage tank, called a flow regulatory structure. You will never see it once it’s completed.” — Joe Little, Reporter, NBC 7, April 9, 2021.

Watershed Survey Helps Maintain San Diego Regional Water Quality

/in , /by

The City of San Diego Public Utilities Department conducts regular surveys of its watersheds to monitor and maintain high water quality within those watersheds.

The City recently released its 2020 Watershed Sanitary Survey. Conducted and issued every five years since 1996 as required by California law, the report identifies actual or potential causes of local source water contamination that might adversely affect the quality and treatability of City of San Diego water.

The updated information is used as a basis for future watershed management and planning efforts. City of San Diego tap water meets all state and federal drinking water health standards, the primary standards for treating and monitoring water.

“Development and other activities in our watersheds can have a profound influence on the quality of our water,” said Shauna Lorance, director of the City of San Diego Public Utilities Department. “The Watershed Sanitary Survey is important for identifying potential negative impacts and ways to better protect our watersheds.”

Watershed protection critical to safe, reliable water supply

A watershed is an area of land that drains water into a specific body of water. Everything that is on the land, whether a natural feature or a human activity, is part of the watershed. Many places San Diego County residents live, work, and play in are watershed areas.

There are 11 westward draining watersheds in San Diego County.  Six are within the City of San Diego: San Dieguito River, Los Peñasquitos, Mission Bay and La Jolla, San Diego Bay, San Diego River, and Tijuana River.

The City of San Diego’s nine water supply reservoirs have a combined capacity of over 550,000 acre-feet and more than 900 square miles of watershed lands tributary to these reservoirs. Local runoff from watersheds captured in City reservoirs accounted for about 11% of total drinking water production from 2015-2020.

Reservoirs are critical components of the regional water supply system, as water is supplied to nearly two million people in the City of San Diego and neighboring communities. Protecting these water sources is vital to providing healthy and safe drinking water. The public can assist in preventing watershed damage through source reduction and preventing stormwater runoff.

The 2020 survey noted these changes since the 2015 Watershed Sanitary Survey:

  • Total area of residential and commercial development in the watersheds increased slightly by about 2%.
  • A total of 412 new construction permits were recorded for onsite wastewater treatment systems located within the watersheds.
  • The number of fires occurring in the watersheds increased by about 8%.
  • Leaking underground storage sites decreased by 53%.
  • Sanitary sewer overflows increased by 36%.

The survey offers recommendations including continuing and expanding public awareness programs to help protect watershed, and implementing projects and programs to improve land management and water quality of source waters. All recommendations will be used for future watershed management and planning efforts.

The full 2020 Watershed Sanitary Survey, as well as past surveys, is available on the City’s website.

Sweetwater Authority Reservoirs Provide Safe Public Recreation 

/in , /by

One year into the coronavirus pandemic, San Diego County’s reservoirs and lakes have provided welcome opportunities for safe, accessible outdoor family recreation.

After shutting down in March 2020, facilities began to slowly reopen through the summer months by carefully implementing safety guidelines, including increased sanitation, social distancing, and restricted attendance to allow San Diegans to resume their favorite hiking, fishing, horseback riding, and bird watching activities.

Sweetwater Authority owns and maintains two popular recreation spots in San Diego County, Sweetwater Reservoir near Spring Valley and Loveland Reservoir, near Alpine.

Primarily a local water supply for Sweetwater Authority’s 200,000 customers in National City, Chula Vista, and Bonita, the agency has created recreational opportunities at the reservoirs. Fishing programs are offered at both reservoirs and a riding and hiking trail at Sweetwater Reservoir is operated by the County of San Diego.

Sweetwater is one of several regional water agencies that offer recreational opportunities at reservoirs and lakes. Helix Water District operates Lake Jennings, a hot spot for trout fishing. The City of San Diego also provides boat rentals and paddle-boarding at several of its reservoirs.

Safety first to protect the public

Both fishing programs and the trail at Sweetwater Reservoir are designed to protect public health and the drinking water supply while benefiting the community.

“At Sweetwater Authority, part of our mission is finding the balance between human and environmental needs,” said Sweetwater Authority Board Chair Hector Martinez. “The recreation opportunities at our two reservoirs are a great example of how we achieve that balance. We can share these beautiful resources with the community while continuing to protect the local drinking water supply for our customers.”

A California Fishing License is required to fish at both reservoirs, and there are rules in place to ensure the protection of the water supply and sensitive habitats surrounding its reservoirs. For more information on current hours, fees, and COVID-19 safety, go to: www.sweetwater.org/fishing.

“The Board and I are proud to offer these recreation programs,” said Martinez. “We encourage the community to take advantage of these opportunities to get outside and enjoy the beauty of our water and the environment.”

Credit Agencies Affirm Water Authority’s Strong Ratings Despite Headwinds

/in , /by

All three major rating agencies – S&P, Moody’s, and Fitch – have affirmed the San Diego County Water Authority’s strong credit ratings, which will help the Water Authority optimize its debt portfolio and minimize the cost of financing important water reliability projects.

The reports cited the Water Authority’s strategic management, its conservative approach to water sales projections, and the benefits of the Water Authority’s rate case litigation that recently resulted in $44.4 million being refunded to local retail water agencies – among many other factors.

Significant challenges

However, rating agencies also noted significant challenges ahead, including efforts by Fallbrook Public Utility District and the Rainbow Municipal Water District to “detach” from the Water Authority – a move that could negatively impact ratepayers across San Diego County. If the two North County agencies leave per their plans, Water Authority analysis shows that the other 22 member agencies will have to pay $16 million to $46 million more per year to cover the cost of the departing agencies.

Moody’s said detachment could lead to a credit downgrade, which would increase borrowing costs for critical water reliability projects. S&P Global called detachment uncertainty “an additional credit stressor” – “especially if an approved detachment sets a precedent if members can easily detach from the authority.” S&P added that, “this would be further exacerbated if the two members are not required to pay for their portion of the associated debt and infrastructure costs that the authority has undertaken to provide reliable water sources.”

Solid financial position

Water Authority General Manager Sandra L. Kerl said, “The Water Authority maintains a solid financial position even in these difficult times, and the credit ratings reflect that. But the challenges are real as well, and they should unify the region to ensure that we continue to benefit from the safe, reliable water supplies we’ve invested in together for the past 30 years.”

In affirming their credit ratings, the services cited the Water Authority’s strong financial leadership, including prudent strategies to manage issues related to COVID-19, its success diversifying water supply sources, its commitment to infrastructure maintenance, and its financial reserves for managing contingencies, among other factors.

  • Fitch Ratings affirmed its AA+ rating and gave a stable outlook on March 15. Fitch noted the Water Authority’s “operating costs are low”  and credited the Water Authority for “significant investments in supply diversification (that) have allowed SDCWA to continue to meet water demands in its service area.” Fitch also accounted for the Water Authority’s current hiring freeze, spending cuts and deferral of $30 million in planned capital spending to proactively manage finances during the pandemic.
  • Moody’s Investors Service affirmed its Aa2 rating and stable outlook March 14. Moody’s said, “the stable outlook reflects our expectation that the Authority’s satisfactory operating performance will continue, supported by strong management practices in the face of challenges associated with variable water supplies, rising costs, and the coronavirus pandemic.” Moody’s added: “Liquidity, including a rate stabilization fund, remains sound serving to insulate the Authority from risks associated with variable water supplies, including California’s (Aa2 stable) current drought conditions, as well as unanticipated events such as the coronavirus pandemic.”
  • S&P affirmed its AAA rating on March 17 and issued a negative outlook based on “heightened business risks associated with potential projected declines in water sales.” On the plus side, S&P cited the Water Authority’s demonstrated ability to navigate highly variable demands and weather cycles. The agency also said, “management is taking important steps” to balance fixed and variable costs, and it praised the Water Authority’s “robust infrastructure maintenance and operational policies.”

Risks include detachment

All three agencies addressed risks, such as additional local supplies that reduce Water Authority sales and member agency detachment. As proposed by Fallbrook and Rainbow, the detachments would allow those agencies to avoid paying for water supplies and infrastructure that have been developed in collaboration with those agencies and are currently being used by those agencies to meet their customers’ needs. Abandoning those cost obligations would force other ratepayers countywide to cover their portion of the bills already incurred for decades of investments in supply reliability.

In May 2020, the Water Authority’s Board of Directors voted to oppose detachment unless four conditions can be met related to protecting Fallbrook and Rainbow ratepayers, avoiding negative impacts for other member agencies, protecting the Sacramento-San Joaquin Bay-Delta, and maintaining the Water Authority’s voting rights at MWD.

The issue is under review by the San Diego Local Agency Formation Commission, known as LAFCO. The LAFCO process, which is designed to provide for an impartial analysis of these issues, will allow the Water Authority and all other affected parties to determine if these conditions are satisfied. If not, the Water Authority will oppose detachment.

Volunteers Offer Birds Eye View at South Lake Reservoir

/in , /by

For decades, it was a source of drinking water for the San Marcos area. Today, the South Lake Reservoir has new life as a local wildlife habitat.

South Lake was built with an earthen dam and provided drinking water to the Lake San Marcos area, most of downtown San Marcos, and the Coronado Hills area. Updates to potable water treatment had detrimental effects on the lake ecology, so the Vallecitos Water District stopped using the lake as a drinking water source in 1984, although it remained an emergency water supply for another decade.

Now, South Lake provides a thriving ecosystem within and around the facility. The lake is home to freshwater fish and abundant aquatic plant life. Waterfowl such as coots, gallinules, grebes, various species of ducks, and cormorants frequent the lake throughout the year. The property is filled with quail, doves, deer, rabbits, raccoons, skunks, squirrels, bobcats, and coyotes.

Volunteers help identify habitat and wildlife at South Lake

Vallecitos Water District staff recently surveyed the area to look for animal tracks and other signs of wildlife, and to catalog plant and animal species.

Certified California naturalists Paige DeCino and Karen Merrill from Preserve Calavera assisted Vallecitos public information representative Alicia Yerman, who is also a certified naturalist. The team spent three days exploring the lake and the 1.4-mile trail. Merrill and DeCino host the volunteer UC Naturalist certification program. The program is currently on hold due to the coronavirus pandemic.

Two wildlife cameras were set up at South Lake to capture wildlife activity over a two-week period. Lisa Urabe, a University of California trained Master Gardener and Vallecitos public information representative, asked the Buena Vista Audubon Society to conduct a bird survey. The BVAS volunteers identified 36 species in mid-February and created a YouTube video showcasing some of the species.

BVAS volunteers were enthusiastic about surveying the birds in an area set aside as wildlife habitat. With increased habitat fragmentation, BVAS hopes the area will remain primarily an area for wildlife.

“What you have at South Lake is a gem of the healthy functioning habitat— flora, fauna, and it is just a complete picture of what we hope our open spaces and natural lands to be,” said Karen Merrill. “It is something we should treasure now and into the future. It is one of a kind here on coastal San Diego County.”

Vallecitos employees take pride in the lake and its surrounding ecosystem and strive to keep the habitat intact for generations to come.

In addition to its value as local wildlife habitat, South Lake is available for fire suppression. Firefighting helicopters can pull water from the lake during wildfire events. The lake may be used as part of the City of San Marcos’ park system in the future.

Water quality within South Lake is monitored daily by water distribution operators, and the condition of the dam’s integrity is recorded weekly. Recently, an environmentally-sound ultrasonic technology made by LG Sonic was placed on the lake to reduce algae blooms and to improve water quality.

Water Main Breaks Decline in San Diego for Fourth Year in a Row

/in , /by

Increased maintenance efforts by the City of San Diego of its water system infrastructure is paying off for ratepayers. For the fourth year in a row, the number of water main breaks has decreased in the City of San Diego. Thirty-three water main breaks were reported in 2020, the lowest total in more than 15 years.

The City credits its aggressive multi-year program to replace aging pipelines for bringing the numbers far below the peak of 131 breaks in 2010.

“The City’s Public Utilities Department has worked very hard to improve the reliability of our water system infrastructure,” said Shauna Lorance, director of public utilities. “Our citizens benefit greatly from fewer main breaks because it means less water loss and lower emergency repair costs.”

San Diego’s continuing program to replace old cast iron water mains has played a major part in the decrease in breaks. Some cast-iron pipes had been in service for more than a century. Since 2013, the city has replaced approximately 180 miles of water pipelines. By 2025, the last 55 miles of cast iron water mains are scheduled to be replaced with water mains made of durable polyvinyl chloride.

Water infrastructure maintenance programs also deliver a benefit to our region’s overall economy. According to the Economic Policy Institute, $188.4 billion spent on water infrastructure investments over five years would yield $265 billion in economic activity and create 1.9 million jobs.

“Improving and maintaining our water infrastructure is an important part of our commitment to serving our customers,” said Lorance. “We will continue to provide reliable water services our customers deserve.”

City of San Diego public utilities crews routinely oversee preventative maintenance work to help determine potential leaks and breaks before they occur. Private contractors have completed the bulk of the pipeline replacement projects under the direction of the City’s Engineering and Capital Projects Department.
