Two actions taken at the Oct. 26 Rainbow Municipal Water District board meeting addressed the construction of the replacement for Lift Station No. 1.
The board approved a $15,181,157 construction contract with James W. Fowler Company and a $1,423,717 professional services agreement with Valley Construction Management for construction management and inspection services. Both actions had 4-0 votes with one vacant seat.
Encinitas, Calif. — Olivenhain Municipal Water District’s Board of Directors unanimously approved today the filing of a notice of completion for the El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project. After over a year of collaboration with the City of Encinitas, OMWD has officially turned the project over to the city. The city will now begin the repaving and bike lane striping portion of the project.
Construction on 8 miles of water pipeline that will be serve as life-blood for the Pure Water Soquel Project, is set to begin on May 24 in Santa Cruz. Three distinct components of building are set to take place during the next several months. From late May until June 15 crews will work around California Street, from the Santa Cruz Wastewater Treatment Facility to Laurel Street. After that, and until around July 6, construction will take place on Laurel Street to Chestnut Street. The third scheduled construction phase will run from July 6 through Aug. 12 on Chestnut to the west end of the Laurel Street Bridge.
San Diego County Water Authority crews recently replaced two pickup truck-sized valves at the agency’s Pressure Control and Hydroelectric Facility in central San Diego – each valve weighing about 35,000 pounds.
The replacement project took place during a scheduled shutdown of a portion of Pipeline 5, which delivers untreated water throughout the county. The pressure-control facility is a key piece of the Emergency and Carryover Storage Project, which ensures water is available around the region if imported water deliveries are disrupted.
Several large-diameter valves in the facility control the pressure and quantity of water delivered to reservoirs and water treatment plants in eastern and southern parts of the county. In addition, a hydroelectric turbine in the facility generates supplemental electricity that reduces the Water Authority’s energy costs while supplying surplus power to the region.
“The new valves will allow the facility to function efficiently at both low and high water flows, depending on regional demand,” said Kirk Whitaker, a senior engineer at the Water Authority. “The project is part of ongoing improvements that enhance the flexibility of our regional water delivery system.”
To perform the valve replacement, a large crane lifted the existing valves out of the facility through the roof and placed them onto flatbed trucks for delivery to a disposal and recycling site. The new valves were then lowered into the facility through the roof and fitted with new 42-inch pipeline sections. Concrete was poured to build pedestals that secure the valves in place.
The new valves were produced in Germany and transported to San Diego by ship. The valve installation process took four days to complete.
The Pressure Control and Hydroelectric Facility serves an important function in improving aqueduct operations and enhancing the flexibility of the Water Authority’s extensive water delivery system. The $21 million facility was completed in 2007 and pressurizes a 22-mile-long section of the Water Authority’s large-diameter Pipeline 5 between San Marcos and Mira Mesa.
The pipeline previously conveyed water in one direction only, from north to south, by gravity. This limited the Water Authority’s ability to move water around the county in the event of a supply disruption. Upgrades to Pipeline 5 now allow water to be transported either north or south using water stored at San Vicente Reservoir, which greatly improves pipeline operations and ensures that water can continue flowing to member agencies.
Pure Water Oceanside is installing new pipelines and drilling wells as the recycled water project continues on track for completion in 2022. The advanced water purification project, and expansion of the City of Oceanside’s existing recycled water system, will deliver a new, local source of high-quality drinking water supplying more than 30% of the city’s water supply when completed.

Residents are kept up to date on construction impacts to streets and other infrastructure through several outreach efforts including an interactive construction map, detailed online schedule, regular newsletters, and virtual open house presentations live on the City of Oceanside’s YouTube channel, offering residents the opportunity to ask questions.
“We understand living and commuting near a construction site is not easy,” said Cari Dale, water utilities director for the City of Oceanside. “Everyone involved with the project is thankful to those residents and business owners who live and work in the construction zone for their patience and cooperation. It is crucial to the successful on-time completion of this vital infrastructure project.”

Pipeline installation is now taking place at North River Road and the Douglas Drive intersection, and moving towards Pala. Lane closures on Douglas Drive allow access to the businesses through the entrance on North River Road.
In addition, pipeline installation on Pala Road is now underway. The road will remain open both ways but will require lane closures.
Well construction, which includes injection and monitoring wells, requires closing a section of Coco Palms Drive (south of Cherrystone Street), which will reduce construction time and impacts to nearby residents. Well drilling will continue 24 hours a day, seven days a week for approximately three weeks until early 2021. During this time, 16-foot sound walls have been installed around the drilling site to direct sound waves up into the atmosphere and away from residents. Night construction lighting will also be mitigated by the sound walls.
After drilling is complete, additional work will be conducted for testing and to install well infrastructure. The post-drilling work will take place weekdays during business hours and occasional Saturdays.

Construction for the entire project is expected to be complete in 2022. While most construction will take place during regular weekday business hours, some critical pipeline construction elements will require temporary extended work hours and occasional Saturdays to complete the project on time.
Residents can sign up for email updates about the project. In the event of any immediate concerns, residents can call 760-435-4570 and representatives will troubleshoot issues.
Unforeseen conditions caused a change order to the Fallbrook Public Utility District contract to replace the pipeline along Winter Haven Road, but it was the only change order needed in the contract to replace approximately 2,570 feet of pipeline. The Sept. 28 FPUD board meeting included a 5-0 vote to approve the change order and also to approve the notice of completion for the project.
Santa Clara County’s largest reservoir will soon be nearly empty, and will stay that way for the next 10 years. Under orders from federal dam regulators, the Santa Clara Valley Water District will begin a project to drain Anderson Reservoir on Thursday, the first step in a $576 million effort to tear down and rebuild its aging dam.
In 1930, while the Great Depression was worsening and the impacts of it were starting to be felt nationwide, the city of Banning received some good news. A major construction project was about to unfold in its backyard, and the city would benefit greatly. The project was the Colorado River Aqueduct of the Metropolitan Water District of Southern California. Starting in the mid-1920s, there had been a series of studies done for bringing water from the Colorado River west to be used in the greater Los Angeles region. In December 1930, the district made the final decision to go with a route that included the San Gorgonio Pass and construction of a major tunnel under Mount San Jacinto.
As a result of the coronavirus pandemic, public agencies have found creative solutions to holding meetings in compliance with the State of California’s meeting laws. Recently, Fallbrook Public Utility District board members stepped away from their video screens, using the opportunity to take a field trip to view a new project while conducting a traveling board meeting.
The Santa Margarita River Conjunctive Use Project is a joint project with Marine Corps Base Camp Pendleton, and will eventually supply about 30% of the District’s water, and virtually all of Camp Pendleton’s water.

At the time of the tour, the project had been under construction for 250 days. Due to COVID-19 and social distancing restrictions, board members and others who attended the traveling meeting stayed in their cars. While behind the wheel, board members wove through parts of Fallbrook to follow the path of the new pipeline. With their smartphones turned on and hands-free, representatives followed each other in a single file parade while listening to a live conference call with the project contractor. Board members learned about construction progress, and saw where and how the pipe will be installed.
The tour and the project began at the treatment plant on Alturas Road, where bulldozers and heavy machinery are moving earth to build the pipeline and a water treatment plant. The pipeline will transport water from the plant through parts of central Fallbrook, ending at McDonald Road. The project also includes a new four million-gallon storage tank, where the tour ended. Participants discussed the possibility of a subsequent tour to view ongoing progress with construction of the facilities.
The entire construction process will take approximately two years to complete, with the pipeline becoming fully operational by 2022.
