When wildfire strikes water, infrastructure that’s made out of plastic is particularly at risk of contamination. If pipes and tanks lose pressure, or get hot, chemicals can leach into the water supply. The CZU Lightning Complex Fire badly damaged seven and a half miles of water supply lines made of polyethylene, a plastic, in northern Santa Cruz County.
A rapid-fire review of potential fixes to the Friant-Kern Canal favors building a replacement canal for 20 miles alongside the existing canal where land subsidence has caused it to sag, severely restricting water flow, according to final environmental documents released Friday.
A House committee will meet Thursday to discuss the deteriorating public health crisis at a Southern California lake. The House Natural Resources Subcommittee on Water, Oceans and Wildlife will review federal and state efforts to address problems at the Salton Sea. The Salton Sea is California’s largest lake at about 350 square miles, fed by runoff from the crop fields of the Imperial Valley, an agricultural powerhouse.
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.
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.
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.
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.
The Aug. 25 Rainbow Municipal Water District board meeting included the award of two pipeline replacement contracts to T.E. Roberts.
The company based in Orange was given a $280,399 contract for the Sagewood Road pipeline and a $301,734 contract for the Nella Lane pipeline. The two contracts were awarded on separate 4-0 votes with Helene Brazier abstaining from both.
Thank you for your support over the past two years. It’s been an honor to serve as the chair of the Water Authority’s Board of Directors. While some may not realize it, this 36-member Board plays a critical role in sustaining San Diego County’s quality of life and economy.
And I’m pleased to say that this Board engages in the difficult discussions and decisions to make sure our children and grandchildren enjoy the same safe and secure water supplies that we enjoy today. Unfortunately, it’s also true that efforts are underway that would undermine decades of successful planning that has served our county well from Fallbrook to San Ysidro.
This week, the Water Authority filed a formal response to address a proposal by the Fallbrook and Rainbow water districts to detach from the Water Authority and annex into Eastern Municipal Water District in Riverside County. These proposals would increase costs for water ratepayers in San Diego County, reduce the county’s voting power, and decrease water supply reliability for farms and residents.
Our detailed filing with the San Diego Local Agency Formation Commission (LAFCO) spells out how the Fallbrook and Rainbow detachment proposals contain significant areas of misleading or incomplete information that must be addressed before LAFCO and all of the interested parties countywide can understand the full scope of impacts that would be created by detachment. The LAFCO process is expected to take at least another year.
As proposed by Fallbrook and Rainbow, the detachments would allow Fallbrook and Rainbow 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.
Our agency’s analysis shows that detachment, as proposed, would reduce water reliability and increase risk for Rainbow and Fallbrook customers, create environmental impacts that haven’t been studied, and impair the successful long-term planning efforts that have served our county well. And it would give Riverside County water agencies more control over San Diego County’s water future, including water rate and property tax impacts. The Water Authority’s formal response to the Fallbrook/Rainbow reorganization proposals and related documents are at www.sdcwa.org/lafco-reorganization.
It’s critical that LAFCO and all the interested parties across San Diego County take the time to address the full scope of consequences created by these unprecedented proposals so we avoid unintended harm to our region. The Water Authority, its member agencies and regional planning agencies such as SANDAG have worked together for more than 75 years to provide this region with safe and reliable water supplies. Trying to turn back the clock now is a costly, difficult process with numerous impacts to Fallbrook and Rainbow customers and across the region.
As we transition to the new Board leadership in October, I trust that you will give incoming Chair Gary Croucher and Vice Chair Christy Guerin the same support that you’ve given to me over the past two years. And don’t forget that whatever the challenges, San Diego County is stronger together.
Analysis released today shows that proposals by the Fallbrook and Rainbow water districts to leave the San Diego County Water Authority and annex into the Eastern Municipal Water District in Riverside County would increase costs for water ratepayers in San Diego County, reduce the county’s voting power, and decrease water supply reliability for farms and residents.
Numerous financial, environmental and legal issues that affect property owners and water users across San Diego County are analyzed in the Water Authority’s formal response to the reorganization proposals filed today with the San Diego County Local Agency Formation Commission, known as LAFCO.
The Nevada Supreme Court ruled Thursday that the state cannot reshuffle existing water rights to prevent environmental damage, despite recognizing a legal principle that requires the government to preserve natural resources for future generations.
Instead, the court ruled that principle, known as the public trust doctrine, is recognized in existing law. The Nevada court, in a 4-2 decision, separated itself from the California Supreme Court, which reached the opposite conclusion in a landmark 1980s case.
The Pure Water Oceanside project is getting a $69 million loan from the U.S. EPA that will finance nearly half of the project’s construction cost.
EPA officials announced the loan at an event today in Oceanside attended by federal, regional and local officials.
The innovative water reuse project will purify recycled water to create a new source of high-quality drinking water that is clean, safe, drought-proof and sustainable. It also will benefit the environment by reducing discharges into the Pacific Ocean. Construction and operation of the plant is expected to create 622 jobs.
Scheduled to be completed by the end of 2022, Pure Water Oceanside will be the first operating advanced water purification facility in San Diego County. The project will provide more than 32% of the City of Oceanside’s water supply, or 3 to 5 million gallons per day.
The port city of Tianjin is in desperate need of water. The surface and groundwater supplies of this sprawling northeast Chinese metropolis have shrunk to dangerously low levels due to decades of reduced rainfall and overexploitation of the Hai River that flows through the city. According to the Tianjin Environmental Protection Bureau, the city’s per capita water resources are one-twentieth of China’s national average, far below the UN benchmark for a water-stressed region. Despite promoting water conservation and metering among residential and industrial users, Tianjin still faces shortages that drive its reliance on large-scale water-supply infrastructure like the South-North Water Transfer Project and seawater desalination.
In the United States, a similar situation is unfolding. After a prolonged drought between 2011-2015, California’s investment in desalination solutions to supply fresh water to the state’s dry south grew exponentially. While most American desalination plants are used to purify less-saline “brackish water” from rivers and bays, large-scale seawater operations have begun to proliferate in California, as well as Florida and Texas. California alone has 11 municipal seawater desalination plants, with 10 more proposed. Southern California-based Poseidon Water LLC opened America’s largest desalination facility in Carlsbad in 2015, which currently meets about 10 percent of San Diego’s water demand. With the capacity to produce 54 million gallons of water a day, this new desalination plant, as well as another one currently in the works at Huntington Beach, could ensure water security in Southern California.
