In a major milestone for water reliability, the East County Advanced Water Purification Program was awarded a $388 million federal loan from the U.S. Environmental Protection Agency to help advance the project’s completion.

Radhika Fox, U.S. EPA Principal Deputy Assistant Administrator for the Office of Water, joined Kyle Swanson, Director of the East County AWP, and Steve Goble, Joint Powers Authority Chair of the East County AWP, for the June 4 announcement at the demonstration facility for the project in Santee. Following the presentation, Fox joined local officials for a tour of the demonstration facility.

“EPA is proud to partner on this project, which uses proven technology to bolster drinking water supplies in this climate-stressed region,” said Fox. “Investing in water infrastructure is one of the best bets we can make to improve public health and the environment, create jobs and address pressing challenges that face our communities.”

The East County AWP is one of only 38 projects selected nationwide to receive a share of approximately $6 billion in federal water infrastructure investments. The Water Infrastructure Finance and Innovation Act (WIFIA) loan is the second-largest loan awarded to any San Diego County project.

“The East County Advanced Water Purification Program is the result of many years of strategic, long-term planning and this WIFIA loan marks a historic milestone in its development,” said Allen Carlisle, CEO and general manager of Padre Dam Municipal Water District. “By providing East County with local control and independence of both its wastewater and water, the program secures a long-term solution for increased stability in our communities and safeguards the vitality of our economy and quality of life.

The East County AWP is a collaborative partnership between the Padre Dam Municipal Water District, Helix Water District, County of San Diego, and City of El Cajon. It will create a new, local, and sustainable drinking water supply using sophisticated technology to provide 30% of current drinking water demands for East County residents when it is completed in 2025, as much as 11.5 million gallons per day.

The project will recycle East San Diego County’s wastewater locally and purify the recycled water at a new treatment facility using four advanced water purification steps. The purified water will then be pumped into Lake Jennings, treated again at the Helix Levy Treatment Plant, and then distributed into the drinking water supply.

Padre Dam Municipal Water District currently imports 100% of its drinking water supply. The agency treats two million gallons per day at its water recycling facility for irrigation and non-potable uses. Helix Water District imports approximately 85% of its drinking water supply with the remaining coming from local sources.

In addition to providing a new local water supply, the project will eliminate the need to send most of East County’s wastewater to the City of San Diego’s Point Loma Wastewater Treatment Plant, where it is currently treated and then discharged into the ocean. Keeping this water resource in east county provides water sustainability and it’s good for the environment.

(Editor’s note: The Padre Dam Municipal Water District, Helix Water District, and the City of El Cajon are three of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)

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.

Water Authority Wins Four Awards for Outstanding Projects

/in , /by

The American Public Works Association and American Society of Civil Engineers recently presented the San Diego County Water Authority with four awards for construction projects that exemplified outstanding skill, dedication and collaboration from staff in many departments. All of the projects were underway or completed during the COVID-19 pandemic, and project teams navigated shutdowns, adapted to health and safety restrictions, and overcame many other uncertainties – in addition to typical challenges encountered during construction projects.

1) APWA Project of the Year: Northern First Aqueduct Structures and Lining Rehabilitation

With extensive coordination between the Water Authority’s Asset Management, Operations, Maintenance, Right of Way, Water Resources, Engineering and Public Affairs teams, the First Aqueduct rehabilitation project was completed in early 2021. Significant work had not been performed on the First Aqueduct since the completion of Pipeline 1 in 1947 and Pipeline 2 in 1954. The Operations and Maintenance Teams worked closely with multiple member agencies to ensure no impacts to water deliveries over the extended shutdowns required to reline both Pipelines. These extended shutdowns allowed the Asset Management team to inspect 27 miles of pipeline along the aqueduct using innovative technologies – the first time this had been done in nearly 75 years.

“Since the project included more than 35 work sites spread out over 15 miles, many in rural areas of the county, we collaborated closely between different departments and member agencies to ensure that water service was not disrupted,” said Emma Ward-McNally, Water Authority engineer.

2) APWA Honor Award: Vallecitos 11/Vista Irrigation 12 Flow Control Facility

This new facility replaced the existing Vallecitos 2/Vista Irrigation 1 facility that was built in 1954. The Water Authority’s Operations and Maintenance team worked closely with the Engineering team to develop a construction sequence to build the new facility while maintaining water service to member agencies.

“A meticulous level of detail in the design process allowed for the project to be completed with minimal changes during construction,” said Jim Zhou, Water Authority senior engineer.

3) APWA Honor Award: San Diego 28 Flow Control Facility

The new flow control facility replaced the San Diego 12 flow control facility. The Water Authority’s Right of Way team worked closely with the City of San Diego to acquire property rights for the facility. During construction, electrical and rotating technicians from Operations and Maintenance provided support to ensure that the facility was constructed correctly and that electrical relay protection was coordinated when connecting to San Diego Gas & Electric.

“The new facility repurposed an existing building at the site, but it was forward-looking – the project included the installation of a second pipe train for a future inline hydroelectric turbine,” said Aaron Trimm, Water Authority senior engineer.

4) ASCE Award of Excellence: Pipeline 5 Emergency Repair

After nearby Pipeline 4 was repaired in late 2019, the Asset Management team inspected Pipeline 5 in early 2020, and found it needed repairs as well. Multiple Water Authority departments and teams collaborated to launch the emergency repairs on Pipeline 5, despite the uncertainty of the growing pandemic. The Engineering Contracts group executed five contracts and task authorizations for design, construction and inspection within a few weeks to make the project happen, and the work was completed in April 2020.

“The project was a true team effort that required collaboration from multiple departments to ensure that the emergency repair could be completed even as the region was shutting down due to the pandemic,” said Colin Kemper, Water Authority senior engineer.

Local Water Districts Get Piece of $44.3M Settlement Refund

/in , , /by /The Coast News Groupby Steve Puterski Quoted: San Diego County Water Authority

A settlement between the San Diego County Water Authority and Metropolitan Water District is delivering a windfall of refunds to local water districts.

The SDCWA filed suits between 2010 and 2018 challenging how Los Angeles-based MWD set rates and imposed charges. SDCWA won several “critical issues” from 2011-14 and was awarded $44.3 million by a state court in January to refund rates and repay overcharges, according to a press release.

SDCWA is also entitled to attorney’s fees and costs for those cases, although the exact amount is to be determined.

The money has been reallocated to its member agencies, with most securing more than $1 million in refunded money.
