The award-winning Hauck Mesa Storage Reservoir enhances drinking water supply reliability and operational efficiency for the region. Construction was completed June 23 on the San Diego County Water Authority project in North San Diego County.

Work started in March 2021 with the demolition of an out-of-service steel tank.

Project work included construction of an underground isolation vault and flow control facility, in addition to a new 2.1 million-gallon water tank connected to the Valley Center Pipeline.

Improved operational flexibility

Operational flexibility is increased at Hauck Mesa by balancing the flow of treated water between the agency’s First and Second Aqueducts and by helping to maintain water deliveries if power supplies are interrupted. The new storage reservoir enhances the Water Authority’s ability to provide reliable and efficient deliveries of treated water to member agencies.

The walls of the new tank are about 60 feet tall, stained a forest green color to blend in with the natural landscape, and made of prestressed, or wire wrapped, concrete.

“The prestressed technology will maintain the tank walls in permanent compression, allowing the tank to accommodate seismic events while remaining watertight,” said Water Authority Construction Manager Emma Ward-McNally.

The project reached a major milestone in April 2022 when crews poured the concrete roof of the new prestressed concrete water tank. The entire system, including the new tank and flow control facility, was put into service in May 2023.

Strategic infrastructure improvements by the Water Authority and its member agencies are part of the regional effort to ensure continued delivery of water to support the region’s $268 billion economy and the quality of life for 3.3 million residents. As part of the asset management program, it is critical to actively replace and repair the Water Authority’s assets, which include pipes, valves, facilities, equipment, and other infrastructure.

Collaboration with Valley Center Municipal Water District

During construction, the Water Authority worked closely with the Valley Center community, Valley Center Municipal Water District, and nearby homeowners to minimize short-term construction impacts during the project.

The Water Authority operates and maintains a regional water delivery system capable of delivering 900 million gallons of water per day. Building and operating the large-scale infrastructure required to meet the region’s water needs now and in the future requires careful planning and technical expertise. The Water Authority uses a sophisticated approach to cost-effectively build, operate, maintain and secure its water facilities as an integrated system.

Neena Kuzmich has been appointed director of engineering for the San Diego County Water Authority – the first woman to lead the Engineering Department since the agency’s formation in 1944. Kuzmich brings more than 25 years of experience as a civil engineer to fill the position vacated by the retirement of Gary Bousquet.

The Water Authority is a regional wholesale water agency that provides about 80% of the water used in San Diego County, sustaining a $268 billion economy and quality of life for 3.3 million residents.

Director of Engineering Neena Kuzmich

Kuzmich joined the Water Authority in 2013 and has 26 years of experience in design, construction, and project management. Prior to her appointment as director, she served as deputy director of engineering. Kuzmich is responsible for overseeing and managing the design and construction of Capital Improvement Program projects, and the implementation of the Water Authority’s energy management policy. She is currently leading efforts to advance the proposed San Vicente Energy Storage Facility.

Kuzmich has a bachelor’s degree in environmental engineering from Syracuse University and a master’s in business administration from University of Phoenix. She is a registered professional engineer in the State of California.

Innovation and excellence

“Gary Bousquet’s expertise and dedication made a profound impact on the San Diego region, which benefits from the projects that he helped develop and lead over the past three decades,” said Dan Denham, acting general manager of the Water Authority. “Thankfully, the Engineering Department will remain in good hands. Neena Kuzmich’s dedication to innovation and excellence will help to sustain the San Diego region for decades to come.”

The Water Authority’s Engineering Department is responsible for the design and construction of regional water facilities in the capital improvement and asset management programs; overseeing energy related projects; managing real-estate interests; patrolling and managing 168 miles of right-of-way property; and providing survey services.

San Vicente Energy Storage Facility

During his 24 years at the Water Authority, Bousquet managed design and construction of Capital Improvement Program projects including the San Vicente Tunnel, San Vicente Pump Station, and the Lake Hodges Hydroelectric Facility. For the past several years, Bousquet and Kuzmich have led the Water Authority’s efforts to develop a major renewable energy project proposed jointly with the City of San Diego. The potential San Vicente Energy Storage Facility received $18 million from the state in 2021, to advance the project through initial design, environmental reviews, and the federal licensing process.

Award-winning engineering department

The department has won several awards in recent years, including the world’s top civil engineering honor for its Emergency and Carryover Storage Project in 2017 from the American Society of Civil Engineers.

Water Authority Director of Operations and Maintenance Eva Plajzer introduced the winning team members at the Water Authority Board of Director’s Engineering and Operations Committee meeting on April 27. Senior Maintenance Technician Bobby Bond, Maintenance Worker II Frank Vargas, and Maintenance Technician Tony Zepeda competed for the Water Authority. System Maintenance Supervisor Luke Holbrook and Operations and Maintenance Manager Al Garza supported the team’s preparation and efforts.

As the overall winning team, the Water Authority trio wins a MSA Trophy for display which, Plajzer joked, “is larger than the National Hockey League’s Stanley Cup.”

Bond, who also won first place in the backhoe competition, explained to board members all the events represent similar skills competitors perform in their jobs performing critical water and wastewater systems maintenance and repairs.

For the backhoe skills test, the operator must use the backhoe to pick up a basketball off a cone, or a ring on a chain, then run through an obstacle course against the clock to successfully place the basketball inside a barrel. The skills needed to pick up small items are the same skills preventing workers from breaking pipes or fixtures.

“They come through every time”

Valley Center Municipal Water District General Manager Gary Arant, who represents his agency on the Water Authority Board, noted the serious purpose of the competition.

“It reflects the skills that we have within the organization,” said Arant during the committee meeting. “Those skills come with years of service and perfecting what they do, training the newer people. We as member agencies benefit, because when we have a shutdown, and we’re waiting for that system to come back up, we count on those skills. They come through every time.”

Friendly competition with serious purpose

While participants enjoy the event and the friendly contest among colleagues, the competition categories test the same skills the participants use on the job while maintaining water and wastewater systems, streets, and other vital infrastructure residents and businesses alike rely on every day.

Bonds is a previous winner of multiple individual categories since 2017 and the 2018 Master Operator winner. Zepeda is also a previous winner in the Wheelbarrow Skills Competition. Vargas was a first-time competitor.

Winners in the equipment competitions will compete at the August 2023 National APWA ROADEO in San Diego.

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.

Major Relining Project Honored by the American Public Works Association

/in , /by

The San Diego and Imperial Counties Chapter of the American Public Works Association recently recognized a San Diego County Water Authority pipeline relining project for its excellence as a public works project. The award commends the successful partnership between Water Authority staff, the contractor and local agencies working together to complete this critical repair to maintain the reliability of the regional water supply.

Relining project covers 12,300 feet

Pipeline 5 was relined from the point of delivery with the Metropolitan Water District of Southern California to Sage Road in the Fallbrook and Rainbow communities in north San Diego County. The $24.7 million project was completed in July 2019 and relined approximately 12,300 feet of Pipeline 5, a 96-inch large-diameter regional pipeline.

30-year pipeline relining program rehabilitates aging pipes

Relining is a cost-effective method to repair pipelines and extend their service life with less impacts to the community and environment than if a traditional pipe replacement is performed. The relining process avoids digging up miles of pipeline, which would take significantly more time and resources, as well as impact associated streets and driveways for a long period of time.

“The Water Authority’s asset management program used an acoustic fiber monitoring system to help perform evaluations of the pipeline and prioritize this portion for rehabilitation,” said Jerry Reed, director of engineering at the Water Authority. “Our staff collaborated with stakeholders in Fallbrook, San Marcos and Rainbow, including staff at our member agencies and nearby residents to ensure project success.”

The project work areas were surrounded by residential homes and farms, heavily traveled public streets and a local retirement community.

Close coordination with multiple agencies ensured there were no impacts to water deliveries. Open communications with local residents regarding project schedule ensured no incidents occurred with local traffic.

Proactive asset management program rehabilitates crucial water infrastructure

The relining project was part of the Water Authority’s proactive and innovative asset management program to rehabilitate and reline pre-stressed concrete cylinder pipe within the Water Authority’s conveyance system to ensure continued supply reliability.

The local APWA chapter chose the project based on criteria that included superb planning, efficient design and construction management techniques to complete the project on schedule, within a cost-effective budget and adherence to regulatory requirements. It was also judged on the degree it enhanced a public service or facility, the quality of community relations or actions to minimize public impacts, safety precautions taken to protect lives and property, environmental impact mitigation measures and other accomplishments under adverse conditions.
