New Seawater Intake Pumps-Carlsbad Desalination Plant-fish-friendly

New Fish-Friendly Seawater Intake Pumps at Carlsbad Desalination Plant

/in , /by

New fish-friendly seawater intake pumps recently commissioned  at the Carlsbad Desalination Plant are among the most environmentally advanced intake pumps in the world.

The three intake pumps, manufactured by Indar, are part of a broader effort to ensure the long-term health of the marine environment near the Claude “Bud” Lewis Carlsbad Desalination Plant, which sits on the shores of Agua Hedionda Lagoon.

New intake pumps and state-of-the-art technology

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 that wasn’t available when the plant was operating with source water from the Encina Power Station. The closure of the power station in December 2018 led to temporary intake-discharge operations until the new intake pumps came online. 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.

Essential work during COVID-19 pandemic

The work to complete the construction and commissioning of the new fish-friendly seawater intake pumps was part of the essential work allowed under California guidelines during the COVID-19 pandemic. The contractor, Kiewit–Shea Joint Venture, worked in accordance with guidelines adopted by the State Building and Construction Trades Council and approved by Governor Gavin Newsom for essential construction. The contractor worked uninterrupted to complete the project per the June 30, 2020, deadline set by the Regional Water Quality Control Board without any health or safety violations.

The eventual transition of the desal plant to operate independent of the power plant was anticipated in the 2012 Water Purchase Agreement between Poseidon Water, which manages and operates the facility, and the San Diego County Water Authority, which purchases the water for use across the region. Currently, the plant provides about 10% of the region’s water supply.

New intakes part of advanced sea-life protection

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, which is among the most advanced sea-life protection measures in the world. Poseidon Water also plans to implement the same state-of-the-art intake system at its proposed Huntington Beach Seawater Desalination Plant in Orange County.

“We are excited to reach this milestone at the Carlsbad Desalination Plant that highlights our commitment to environmental stewardship,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “This plant will continue to be a vital regional resource for decades to come, and it demonstrates that environmental enhancements can go hand-in-hand with water supply sustainability.”

Carlsbad Desalination Plant improves sustainability

The Water Authority can purchase up to 56,000 acre-feet of water from the Carlsbad plant per year – enough to serve approximately 400,000 people annually. The new pumps, combined with additional future investments, will continue to provide the San Diego region with a critically important drought-proof water supply from the Pacific Ocean.

The plant is a major component of the Water Authority’s multi-decade strategy to increase the county’s water supply reliability through supply diversification. San Diego County’s water portfolio approach has been successful in minimizing the region’s vulnerability to drought and other water supply emergencies.

“Using the most advanced technology for the seawater intake system builds on the Carlsbad Desalination Plant’s long history of protecting and preserving the coastal environment,” said Poseidon CEO Carlos Riva. “The new intake system will make this one of the most environmentally sensitive desalination plants in the world, and further enhance our region’s water reliability and climate resiliency.”

New Helix Water District Connection Improves Emergency Communication

/in , /by

East San Diego County firefighters and first responders will be better prepared to respond to emergencies due to improved communication capacity through a new partnership with the Helix Water District. The Heartland Communication Facility Authority recently installed a new radio repeater on Helix Water’s Calavo tank, located near Mt. Helix.

“When public agencies work together to improve the lives of our citizens, everyone benefits,” said Helix Board President Mark Gracyk. “We are delighted with the outcome and are very proud to participate in making East County a safer place to live.”

Heartland’s goal is to provide its customers with the highest quality of public safety communications services. Heartland provides public safety communication services to 13 fire agencies throughout East San Diego County. It uses a universal radio system – known as a VHF radio – to communicate with fire agencies and first responders.

Though reliable, the hilly terrain of East County can interfere with VHF radio communications. As part of its effort to improve communication in El Cajon and Spring Valley, it needed a suitable location to install a radio repeater between the two communities. The Calavo storage tank was ideally positioned to play home to the new repeater. Heartland approached Helix to work out an agreement.

“Heartland Communications Facility Authority knows the needs of our local emergency communication infrastructure,” said Dan McMillian, Helix Water District board member. “When Heartland approached Helix, our board saw this as an opportunity for our two agencies to work together for the benefit of the communities that we serve.”

“The addition of a radio repeater on the Calavo Drive water tank will allow firefighters from throughout the state who respond to the East County to communicate with each other and the dispatch center using this repeater,” said Carlos Castillo, Director of Heartland Communications. “Communications are an integral part of the firefighting effort in suppressing wildland fires, and firefighter safety relies on an effective communication infrastructure.”

Construction started in March 2020 and was completed in June 2020. Improvements at the Calavo site included installing a new radio repeater and a four-foot antenna at the top of the tank. As part of the project, San Diego Gas and Electric installed a new electric service and meter at the site so Heartland’s equipment can operate independently from Helix’s pumps and monitoring equipment.

“Heartland Communications would like to thank Helix Water District for allowing us to install our VHF repeater on their water tank,” said Castillo. “This collaboration between Helix and Heartland is a win-win for the fire service and the community. It will provide the critical communications infrastructure needed to enhance public safety.”

The Heartland Communication Facility Authority provides emergency communication services for its member agencies, which include Alpine Fire, Bonita Fire, San Miguel Fire, City of El Cajon, City of La Mesa, City of Lemon Grove, Lakeside Fire, City of Santee, Barona Fire and Viejas Fire.

The Helix Water District treats and delivers water to 277,000 people in La Mesa, El Cajon, Lemon Grove, and parts of Spring Valley, Lakeside, and unincorporated San Diego County.

Technology-Asset Management-Pipelines

Pipelines Assessed in Record Time with Latest Technology

/in , /by

The San Diego County Water Authority’s asset management team recently celebrated the completion of a comprehensive condition assessment of more than 27 miles of the agency’s oldest pipelines. The assessment was performed in record time over just 16 months.

The work was part of a package of rehabilitative efforts on a portion of the First Aqueduct, which includes Pipelines 1 and 2 in North San Diego County. Built in 1947 and 1952, the two pipelines deliver treated water to the region and were constructed using various materials, including reinforced concrete and steel.

Proactive asset management team makes critical repairs

As the pipelines were inspected, areas that required immediate attention were identified and repaired, thereby minimizing future disruptions to water service and impacts to the surrounding environment. Sections of the pipelines requiring future repairs were added to a list of upcoming projects prioritized by the risks and associated costs.

“The asset management team took advantage of scheduled pipeline shutdowns, and with careful coordination, assessment work was performed concurrently with other major rehabilitation efforts in the region,” said Martin Coghill, operations and maintenance manager at the Water Authority. “This innovative approach saved time and avoided unnecessary disruptions in service to our member agencies.”

Throughout the condition assessment process, Water Authority staff worked closely with staff from member agencies to coordinate work being performed in their service areas and any potential impacts. Proactive repairs are crucial to ensuring the reliability of the regional water supply.

Collaboration with multiple contractors to perform complex work

In 2016, a search was conducted to find the best technologies to perform critical assessments to maintain the reliability of the pipelines. It resulted in a multi-technology, multi-contract approach.

The Water Authority partnered with multiple contractors to perform the complex work:

  • Diakont, based in Carlsbad, Calif., used its robotically-mounted technologies to inspect steel pipe sections. High-resolution LASER Profilometry and Electromagnetic Acoustic Transfer technology located internal and external corrosion defects that were then repaired by welding steel patches on the inside of the pipe. This method avoided costly excavations and environmental impacts.
  • Pipeline Inspection and Condition Analysis Corp., based in Edmonton, Alberta, brought its sophisticated Remote Field Technology to San Diego County to scan most of the reinforced concrete pipe using an innovative tool that moved through the pipe at a controlled speed. The technology had been previously used by the Water Authority and consistently demonstrated a high level of accuracy.

  • Pure Technologies, a Xylem company with an office in San Diego, deployed its Near Field and Remote Field electromagnetic inspection tools to assess portions of the reinforced concrete pipe. With a focus on lightweight components, both tools were successfully conveyed through the pipelines using personnel with rope and pulley support.

The focus on the Water Authority’s First Aqueduct is the latest chapter in the agency’s long-running strategy to assess critical pipelines and ensure the maximum lifespan is achieved with the most cost-effective methods. Proactive asset management efforts first began in the 1990s and were consolidated into the Asset Management Program in 2009. To date, more than 150 miles of the Water Authority’s total 310 miles of large-diameter pipelines have been assessed using cutting-edge technologies.

The asset management team collaborates with local, national and international organizations in the asset management and water infrastructure fields, focusing on knowledge sharing and asset life optimization.

Construction near San Marcos homes required creative thinking and community cooperation from the Vallecitos Water District to successfully complete the project. infrastructure

Community Outreach Makes Challenging Infrastructure Update a ‘Walk in the Park’

/in , /by

In its efforts to maintain its critical infrastructure, the Vallecitos Water District undertook a challenging update to a wastewater system pipeline constrained by its precarious location.

The existing eight-inch gravity sewer pipeline conveys wastewater from the intersection of Rock Springs Road and Bennett Avenue west through a greenbelt area to an existing 12-inch pipeline in Rock Springs Road at Lancer Park Avenue. To expand capacity for current and future growth, it was replaced with a new 15-inch PVC pipe west of Matthew Lane and a 12-inch PVC pipe north and east of Matthew Lane.

See video following the progress of this vital infrastructure project

The District always prefers to perform work in a street or public right-of-way. Neither were possible for this project due to its greenbelt and park location within feet of residential homes.

“We took every environmental precaution prior to construction,” said Lito Santos, Vallecitos Water District Project Engineer. “We performed a nesting survey, a raptor survey, and we also worked to tunnel under the bridge,” within the Environmental Protection Agency’s “Clear Water Rule.”

San Marcos Woods Homeowners Association board member Ross Fisher acted as a liaison between homeowners and the HOA with the District. Fisher expressed concern about access to the work area by the District’s large combination truck. The original proposal to create a concrete strip to drive over wasn’t feasible.

Working together with Vallecitos Water District engineers, the group chose an alternative material called “grass-crete.” Grass-crete is a green porous paving solution that comes in easy-to-install rolls. It’s flexible, lightweight, durable and provides design versatility to the project. Due to its incredible strength, the grass-crete and existing lawns can handle the weight of a large service vehicle driving on it without significant damage.

Proximity to additional threats

Manholes were waterproofed, coated, and sealed as an additional precaution and to extend their longevity.

Vallecitos Water District engineers also worked with San Diego Gas & Electric to perform its work with enough safety clearance from a 16-inch transmission main artery gas line pressurized at 800 pounds per square inch. The District secured permission to dig within two to three feet from the line instead of the standard five feet.

The work area is also prone to flooding after large rain events, raising the water levels in the nearby creek high enough to infiltrate and inflow into the manholes. The District moved the manholes clear of the creek embankment, and lifted the manholes two feet above ground and clear of the flood plain to prevent runoff intrusion. Manholes were waterproofed, coated, and sealed as an additional precaution and to extend their longevity.

“Overall Vallecitos left the greenbelt area as good or better when they started,” said Fisher of the HOA. “On a scale of one to ten, I have to give them a 9.5 or a ten. Working with the inspectors and Lito Santos the engineer, everything we asked for was done in a timely manner.”

“The project was a huge success,” said Santos. “Working with the Vallecitos Engineering Team, the Inspection Team and Mr. Fischer, it was not just a Vallecitos highlight but a career highlight.”

Sweetwater Authority Taps Innovative Technology to Ensure Water Quality

/in , /by

The Sweetwater Authority recently began a multiyear water main flushing program using innovative technology to clean all 400 miles of pipeline in its system. It’s part of Sweetwater Authority’s use of the latest technology to deliver a safe, reliable water supply to its South San Diego County customers.

Water main flushing cleans pipeline interiors by sending a rapid flow of water through them. Sweetwater’s program is the first in the region to use a new, innovative technology resulting in less environmental impact.

“We’re committed to providing our customers with high-quality water, ensuring that every drop meets safety standards and protects public health,” said Tish Berge, Sweetwater Authority general manager. “We’re also dedicated to providing the safe, reliable water through the use of best available technology and sustainable practices.”

See the system in action in the following video. A Spanish language version is also available.

New method avoids storm drain discharge

Traditional flushing methods release water from fire hydrants at a high speed in order to flush out naturally occurring sediments accumulating in water pipes over time. Although the sediment itself is harmless, it can eventually affect water color and taste. The water used to clean the pipes often cannot be captured and ends up in the storm drain system.

The bulk of Sweetwater Authority‘s flushing program now eliminates the need to discharge water from fire hydrants during the cleaning process while delivering the same results.

With the closed-loop system and increased controls, crews are able to effectively and thoroughly flush large sections of pipeline with a single setup and staging area. This more efficient setup is less labor-intensive and allows the crew to maintain a safe hub for operations. Photo: Sweetwater Authority

Crews identify all pipes, valves, and fire hydrants located in the area to be flushed. Next, crews connect one end of a hose to a hydrant and the other end of the hose to the no discharge, or NO-DES flushing unit. The process repeats, connecting a second hose to another hydrant and the other end back into the flushing unit, creating a temporary closed loop.

Once the NO-DES flushing unit is turned on and the hydrants are open, water will push through the loop at high pressure, disrupting any accumulated sediment on the inside of the pipes. The water is pushed through a series of sock-like filters, which remove those sediments and return clean, high-quality water back into the system.

Crews closely monitor the filtration system and water quality to determine when flushing of each pipeline segment is complete.

Innovative technology, efficient and environmentally responsible

In the National City area 75.8 miles of pipeline was recently flushed. Crews are now completing work in the Bonita area, and then will start work in Chula Vista.

Additional water agencies have indicated an interest in the cost-effectiveness of purchasing the NO-DES flushing units for the region and collaborating to create a shared-use program with the innovative technology.

“Securing a local water supply to ensure the water delivered is of the highest quality through the best technology in our projects and programs helps to maximize value for our customers while also being sustainable,” said Berge.

Vallecitos Water District Crews Rehab Manhole, Protecting Environment  

/in , /by

Vallecitos Water District crews sprang into action to repair and rehabilitate a manhole in danger of failing, successfully preventing a spill, which could have resulted in significant environmental damage.

Located just off Palomar Airport Road in a shared 30-foot easement with the Buena Sanitation District in Carlsbad, the manhole is part of a 30-inch outfall providing a main sewage drain for the City of San Marcos. The line feeds directly into the Encina Wastewater Treatment plant a half-mile from the project site.

Originally constructed in the 1980s, turbulence generated by a hard right-turn along the sewer easement creates hydrogen sulfide gases. These gases corrode concrete and weakened the manhole over the years. Flooding also occurs in the area and allows rainfall to infiltrate the manhole.

Preventing harm to sensitive habitat areas

Vallecitos Water District staff became concerned the structure could fail. The result would be a major sewage spill affecting the nearby Encinas Creek Habitat Conservation Area, ultimately spilling into the Pacific Ocean a mile downstream. The Habitat Conservation Area is owned by the Center for Natural Lands Management, which supports its management through an endowment.

The Encinas Creek HCA is also part of the City of Carlsbad’s habitat management preserve. It includes riparian habitat and is known to be home to state and federally protected species. The Center for Natural Lands Management works to protect the property from trespassing, nonnative invasive plant and animal species, and other issues.

The District determined emergency repairs were required. Although the Vallecitos Water District has proper easement rights to access, operate, and maintain the pipeline, the agency must avoid any impact to the existing habitat while repairing the manhole. This required some creativity by the work crews.

Creative thinking provides access for repairs

The District kept all construction activities within its existing easement to avoid any impacts to existing riparian vegetation. Crews constructed a temporary bridge over an existing stream obstructing access to the manhole. The bridge installation was designed to be temporary, and not affect the existing stream with footings or other supports. Constructing the bridge for access turned out to be the most complex part of the repair project.

District crews working with a contractor team took advantage of the lower sewage flow during the early morning hours, starting work at 3 a.m. to get as low into the waterline as possible. Repairs like this take advantage of the low flows to keep critically important sewer systems in operation.

Instead of replacing the manhole, the District used a polymer concrete replacement product to build a new manhole within the old manhole. As a result, no excavation was needed. Unlike regular concrete, the new material is corrosion-proof and should provide District customers in San Marcos with many years of reliable service while protecting the environment.

Lake Jennings in Lakeside, operated by the Helix Water District, will also reopen for recreation and day-use on Saturday, June 13. Hours are limited to weekends from 6 a.m. to 3 p.m. Fishing and day-use visitors must wear masks and adhere to social distancing. The Bait and Tackle Shop will be open with restrictions. Shore fishing and private boat launching are available, but no boat rentals, night fishing, or fish stocking at this time.

In addition, Lake Jennings recently reopened for camping on June 5 with restrictions in place limiting use to every other campsite, and only by members of the same household. See the complete list of restrictions at the Lake Jennings website.

“We are thrilled to be able to reopen in compliance with the County regulations,” said Kira Haley, Lake Jennings recreation manager. “We really appreciate your understanding in this difficult time while we continue to work hard to keep our community safe.”

The public will be asked to observe COVID-19 preventative measures, including mandates requiring face coverings and physical distancing.

Santee Lakes, operated by the Padre Dam Municipal Water District, expanded recreational use including fishing with some restrictions on May 16. All activities with physical distancing are allowed including jogging, bike riding, roller-skating. A facial covering is not required during physical activities but must be in your possession. Physical distancing and possession of a facial covering are required while fishing. The lake’s campsites have remained open throughout the pandemic, but campers must practice social and physical distancing while on site.

County of San Diego to help cover costs

The cost of reopening the City of San Diego’s additional reservoirs is approximately $1 million. Funding identified through a tentative cost-sharing agreement with the County of San Diego will be limited to covering enhanced staffing costs for ensuring public health is maintained in response to the COVID-19 pandemic. Both the City Council and San Diego County Board of Supervisors will need to approve the agreement.

Stimulus Funds Would Create Regional Jobs, Enhance Water Reliability

/in , /by

Water suppliers in San Diego County say future COVID-19 federal and state stimulus packages should include funding for shovel-ready projects that would create jobs in the region.

In a letter to members of California’s congressional delegation, a group of 13 agencies, including the San Diego County Water Authority and 10 of its member agencies, and the cities of Del Mar, Oceanside and Poway, say the region’s water utilities have dozens of infrastructure projects that could be launched with an infusion of state and federal stimulus funding.

“As the water suppliers throughout San Diego County, across the state, and around the nation are confronting the unprecedented impacts of the COVID-19 pandemic, there are several actions that the federal government could take to provide some much-needed relief,” according to the letter dated May 31.

From replacing valves in pipelines to building water purification facilities, to developing a major pumped hydropower energy storage project for the region, the funding boost would advance efforts to enhance water reliability and increase jobs across San Diego County.

Financial stress, economic fallout from pandemic

The letter requests the following action items be supported as Congress discusses additional legislative relief packages:

  • Allow for use of federal funds to backfill for lost revenue: The largest issues that water suppliers are currently facing are the immediate budgetary impacts and the ongoing effects of lost revenues. Allowing water systems to use federal funds to fill the gap being created by lost revenue would provide significant assistance to prevent layoffs or furloughs, minimize project deferrals or delays, and help avoid other associated impacts that may have a lingering negative effect on regional economies. An analysis produced last month by the Association of American Metropolitan Water Agencies and the American Water Works Association estimated that drinking water utilities throughout the county are facing an annualized revenue loss of approximately $13.9 billion as a result of the pandemic – a sum equal to nearly 17% of the sector’s annual revenue.  We strongly encourage Congress to set aside robust funding for water utilities to help offset these fiscal losses. Otherwise, ratepayers will face escalating costs and reduced economic activity related to delayed capital investments, which will only further hinder the nation’s, state’s, and region’s economic recovery. 
  • Extend the Emergency Payroll Tax Credit to Public Entities: The “Families First Coronavirus Response Act” required public employers to provide paid sick and family leave, yet the law excludes these same employers from receiving payroll tax credits made available to private employers. Extending this tax credit to local governments would help cover the costs associated with these programs.
  • Restore advance refunding for tax-exempt bonds: This action would allow flexibility for local government entities to access billions of dollars to reallocate and spend on other projects and priorities, which would be much needed during this time.
  • Aid to low-income ratepayers: COVID-19 response legislation should also include a separate component to ensure that low-income customers are able to afford to keep up with their utility bills throughout the pandemic. Without federal assistance targeted at these customers, some low-income households will fall even further behind on their bills, making it that much more difficult for them to catch up with their payments once the crisis ends.

San Vicente Energy Storage Facility

Pumped Energy Storage-WNN-June 2020-graphic

Pumped energy storage facilities are part of an integrated and sustainable energy system that includes the production, storage and distribution of clean energy.

Regional energy project needs regulatory path

One of those shovel-ready projects does not require any state investment or financial assistance to generate economic stimulus. But it needs a regulatory path forward, which could come in the form of state legislation or decisions by the California Public Utilities Commission.

The Water Authority and the City of San Diego have been working on the San Vicente Energy Storage Facility project for several years. All equity and debt financing would be provided by a private investor.

Generating renewable energy and jobs

The project would create a small upper reservoir above the existing San Vicente Reservoir, along with a tunnel system and an underground powerhouse to connect the two water bodies. The powerhouse would contain up to four reversible pump turbines.

During off-peak periods – when power is inexpensive and renewable supplies from wind and solar facilities exceed demand – turbines would pump water to the upper reservoir where it would act as a battery of stored energy. During peak energy use, the system would create clean energy as water from the upper reservoir flows downhill through the turbines.

“Our developer estimates the project could generate more than 50,000 hours of preconstruction work, followed by more than 1,000 jobs during a four-year construction period,” said Gary Bousquet, with the San Diego County Water Authority. “When it’s completed, the facility could store huge volumes of renewable energy and then use that energy when renewables are not available, such as nighttime.”

Bousquet said the project, when completed, would also generate additional revenue to offset water agency costs and help stabilize water rates.

To prevent water main breaks and ensure reliable service to its customers, Olivenhain Municipal Water District is proactive in its repair and replacement of aging water infrastructure.

Year-long construction project underway

In early April, OMWD began construction to replace aging water infrastructure along El Camino Real in Encinitas. The work marks the start of the El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project. Construction is expected to last about one year.

During the project, OMWD will replace 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 will also be replaced.

The two pipelines being replaced were originally installed in 1961 and 1974, and are approaching the end of their lifespan.

The American Society of Civil Engineers estimates that there more than 240,000 water main breaks in the United States every year. The main breaks waste over two trillion gallons of treated drinking water, but also interrupt water service to homes and businesses, and require costly and disruptive emergency repairs.

After OMWD’s pipeline work is complete, the City of Encinitas will implement traffic calming measures and improve safety and mobility for bicyclists along North El Camino Real from Encinitas Boulevard to Leucadia Boulevard by restriping and narrowing travel lanes.

The work will include adding bollards to existing bike lanes, applying green color to some areas on the bike lanes, and additional signage and pavement markings will also be installed.

OMWD will implement the lane restriping portion of the project on behalf of the City of Encinitas, which will take place concurrently with the pipeline replacement project.

Coordination minimizes impact on residents and businesses

The two agencies have combined efforts to maximize operational efficiencies and to reduce impacts to area residents and businesses.

Originally, OMWD’s project was scheduled to begin in 2021. Encinitas Council Member Joe Mosca and OMWD Board Treasurer Larry Watt identified the opportunity to streamline the two projects, maximizing efficiencies and minimizing impacts to the community. Because the City’s project had a deadline for grant funding, the two agencies ultimately decided it would be more efficient to advance the timeline of OMWD’s project.

“El Camino Real is a major thoroughfare and any work done there needs to be executed with maximum care and efficiency in mind to keep impacts to businesses and residents low,” said Larry Watt, OMWD board treasurer. “By coordinating the pipeline replacement project with the City’s project, the community can enjoy a continued safe and reliable water supply and improved road safety with the least disturbance possible.”

Environmental responsibility and safety

“The City of Encinitas is continuing its track record of environmental responsibility by making our streets safer for bicyclists and pedestrians through the Active Transportation Enhancing Project,” said Encinitas Councilmember Joe Mosca. “The City’s partnership with OMWD on this project highlights the benefits of collaboration between neighboring public agencies on critical infrastructure projects.”

In addition to the partnership, OMWD has taken steps to minimize the impact of the project on residents and businesses along North El Camino Real. A City-approved traffic management plan will be implemented during construction. All work was originally scheduled to be completed at night to minimize traffic impacts.

As a result of the reduced traffic from the statewide stay-at-home order, the agencies adapted hours in April to 7:30 a.m. to 6 p.m., Monday through Friday. The change allows work to be completed more efficiently and safely.

Olivenhain will work closely with the City to monitor the project’s impact on traffic on a week-by-week basis and modify the schedule as needed along with project contractor Teichert Energy and Utilities Group while still maintaining efficient operations.

OMWD anticipates a single shutdown of water service for most businesses/residences, kept as short as possible. Project updates are posted on its website. Email questions to or call 760-632-4235.
