While health and safety of our water supply remains our top priority, reliable water service is an enabling force for economic growth and improves the quality of life for families. According to a recent study by the American Society of Civil Engineers and the Value of Water, the United States needs to invest $109 billion per year in water infrastructure over the next 20 years to close the water infrastructure gap.
The West Valley Water District Board of Directors has approved a series of critical water infrastructure improvements for North Fontana residents in Zone 7. The actions will ensure that WVWD will be able to better maintain and control the steady flow of water to the area’s residents, WVWD said in a news release on Sept. 22. The project is located west of Citrus Avenue and north of Interstate 15.
The plan to fix subsidence in the Friant-Kern Canal and restore water deliveries to farmers in southern Tulare County and Kern County got over a major hump last week. On Sept. 18, the U.S. Bureau of Reclamation, which owns the Friant-Kern Canal, released final environmental documents for its plan to repair a 33-mile stretch of canal between Lindsay and McFarland. The final environmental impact report represents a significant milestone in beginning work to restore flows to the lower third of the 153-mile long canal running along the Valley’s east side.
The San Diego County Water Authority is partnering with the Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and improve water management before, during, and after those seasonal storms.
This month, Scripps’ Center for Western Weather and Water Extremes (CW3E) launched the Water Affiliates Group, which brings together cutting-edge science and hands-on water industry experience to enhance reservoir operations in light of the changing climate. The Water Authority has a long-running alliance with Scripps and is among six founding water agencies statewide.
CW3E and its partners will share and support best practices in forecast-informed reservoir operations, increase research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.
“This partnership with Scripps Institution of Oceanography underscores our commitment to strategic, science-based decision-making and long-term planning,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “By supporting advances in forecasting, we can more efficiently and effectively manage water resources both locally and statewide. This ultimately will benefit everyone in California by helping sustain our economy and quality of life.”

Water Authority General Manager Sandra L. Kerl said the collaboration aligns closely with Governor Newsom’s Water Resilience Portfolio, which prioritizes voluntary agreements, smart water storage strategies and coordination of data collection.
“This is a great example of how water agencies are stronger together by addressing major climate challenges that affect everyone across the arid West,” Kerl said. “By combining forces with some of the leading scientists in the world, we will enhance our planning capacity and be ready to adapt to whatever the future brings.”
Atmospheric river storms cause 40% to 60% of annual precipitation and most of the flood damage on the West Coast. Managing reservoirs for both flood control and drinking water supply retention is challenging because 20th-century practices and regulations are decreasingly relevant due to changing patterns for snowmelt and rainfall.

CW3E is a leader in Forecast Informed Reservoir Operations, which uses data from watershed monitoring and modern weather and water forecasting to help water managers determine the best strategies for retaining or releasing water from reservoirs. CW3E has numerous tools and technologies that affiliates can use to augment water research and improve on-the-ground decisions of water managers. The group’s research covers water supply reliability, flood management, greenhouse gas mitigation, groundwater recharge, public safety, observations, forecasting, decision support, climate outlooks, and hazard assessment.
The Water Authority is working with CW3E to assess how better near-term and long-term precipitation forecasts can improve reservoir planning and operational management in the San Diego region by maximizing local water supplies and the reliability of water resources through a mix of planning processes and real-time decisions.
Joining the Water Authority as founding partners are Sonoma Water, Orange County Water District, Yuba Water Agency, Turlock Irrigation District, and Irvine Ranch Water District.
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.
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.

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.

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.
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.

Since 2005, the San Diego Integrated Regional Water Management Program has supported and funded water conservation, water quality and resource projects throughout San Diego County.
Program partners, including staff of the San Diego County Water Authority and its 24 member agencies, the California Department of Water Resources, and regional water industry leaders, met at the Water Conservation Garden at Cuyamaca College Monday to celebrate 15 years of achievements.
The program facilitates collaboration on water resources planning and projects in the region by water retailers, wastewater agencies, stormwater and flood managers, watershed groups, the business community, tribes, agriculture, and nonprofit stakeholders.
The San Diego County Water Authority Board of Directors today approved a contract with Sandra L. Kerl to be the new general manager of the region’s wholesale water agency, following a months-long national search. The Board approved the contract in open session during its regular monthly meeting at Water Authority headquarters.
“Sandy brings an ideal mix of leadership, experience and vision to guide the Water Authority into a new decade as the agency seeks innovative solutions that benefit San Diego County and the Southwest,” said Water Authority Board Chair Jim Madaffer. “Her creativity and collaborative approach ushers in a new era of partnerships and progress that has marked her work over the past eight months.”
The Vallecitos Water District is moving beyond traditional bill mailers and tri-fold brochures to communicate with its customers in a more effective and dynamic way by using video.
Vallecitos Board President Hal Martin conceived the idea to create “Work We Do” videos to help customers see and understand first hand the complex work Vallecitos water professionals perform to ensure reliable water and wastewater services. Viewers see and hear from the workers in the field as they complete tasks such as replacing outdated equipment or using smoke testing to detect sewer leaks and protect the environment.
“I’ve seen the quality of staff videos and I realized it was the perfect way to show our customers exactly what we do,” said Martin of the series and the initiative.
Watching crews in action providing the community with reliable drinking water and wastewater services, protecting the environment, and developing the next generation of water workers, makes customers better informed citizens about the area’s vital infrastructure in a transparent way.
The video series also includes helpful information such as how to read water meters.

“We’re working to change our Public Information Department and keep up with current technology,” said Chris Robbins, Vallecitos public information and conservation supervisor.
Robbins said the goal is to feature each department within the district and focus on topics that lend themselves to visual communication. Videos run three minutes or less to keep the audience engaged.
Finished videos are posted to the district website, YouTube, Facebook and Twitter. The videos can also be seen on the City of San Marcos news channel, San Marcos TV. Videos are also shared through water industry news websites such as Water News Network.
Alicia Yerman, a Vallecitos public information representative, shoots and edits the video series. She schedules time to join crews at work when performing a specific task. She also plays talent scout, finding a knowledgeable employee who can describe the work on camera.
Not all staff want to talk, but Yerman is able to coax at least one Vallecitos staff member to be the ‘on camera talent,’ and she also has a knack for bringing out their best. She finds ways to make staff more comfortable being on camera—either by asking questions or placing staff members in comfortable settings.
Yerman and Public Information Representative Lisa Urabe were recently certified as drone pilots. Future videos will feature district work from a bird’s eye point of view.
Were San Diego on its own, there wouldn’t be enough water to go around. Only about 5 percent of urban San Diego’s water comes from local rainfall, an almost meaningless amount that wouldn’t support our region’s 3 million residents.
San Diego County residents strongly support efforts to continue improving water supply reliability and they largely trust local water agencies to do that work, according to a regional public opinion survey released today by the San Diego County Water Authority.
An overwhelming majority (94%) of respondents favor expanding the use of recycled water for agriculture and irrigation, and 79% support purifying wastewater to drinking water standards with advanced treatment technologies.
In addition, 71% of respondents back efforts by the Water Authority to store water in Lake Mead on the Colorado River for use during droughts and emergencies, and to help avoid water shortages on the river.
Nearly two-thirds (64%) of respondents understand that providing safe and reliable water supplies is more costly in San Diego than many other parts of the country, and many indicate a willingness to make additional investments. More than 6 in 10 (64%) residents say they would pay $5 more a month to increase reliability and enhance local control over water supplies, with 50% showing willingness to pay $7.50 more per month, and nearly half (45%) saying they would pay $10 more each month.
“Our region’s residents appreciate the importance of maintaining safe, reliable water supplies and the role of public water agencies to support our $231 billion economy,” said Water Authority Board Chair Jim Madaffer. “They also recognize that continuing to develop locally controlled water supplies – while making efficient use of existing sources – is critical for our future.”
The survey also makes it clear that San Diego County residents remain committed to using water efficiently even though the region’s water supplies are sufficient to meet demands. Ninety-two percent of respondents agree that water-use efficiency is a civic duty, and 70% say they have taken actions to reduce their home water use in the past 12 months.
The Water Authority has performed periodic public opinion research over the past two decades to gauge residents’ knowledge and attitudes about water issues. The latest survey of 1,063 adults in San Diego County was conducted by Encinitas-based True North Research from Aug. 16 to 27, and results were provided to the agency’s Board of Directors during today’s regular monthly meeting.
Survey results show that affordable housing is the most prominent top-of-mind issue (31%) in the region, followed by homelessness (21%) and cost of living (12%). Only 3% of respondents mentioned water-related topics such as drought, cost or quality as the most important top-of-mind issue facing San Diego County. Four years ago, when statewide drought conditions were peaking, water issues ranked first (33%).
The latest survey also indicates that almost everyone agrees that a safe, reliable water supply is important for a healthy regional economy (94%) and San Diego’s desirable quality of life (93%). That’s a key tenet of the Water Authority’s ongoing Brought to You by Water outreach and education program, and an increase from prior years.
When it comes to supply reliability in San Diego County, more than half (52%) of respondents expect it to improve or stay about the same over the next year. Residents were divided in their optimism over the region’s long-term reliability. While 42% expected supplies to improve or remain the same over the next 20 years, 48% thought supply conditions would worsen. However, nearly two-thirds (65%) of respondents trust local water agencies to ensure a reliable water supply over the long-term.
The 2019 survey also explored issues of cost. The survey showed that few residents know how much they pay for a gallon of tap water. After being told that the retail cost of municipal tap water in the San Diego region is about one cent per gallon, nearly 6 in 10 (58%) respondents said tap water is an excellent (29%) or good (29%) value, with 24% percent saying it is a fair value.
On the topic of water rates, nearly 6 in 10 (59%) survey respondents agree that additional increases may be necessary to increase the reliability of our region’s water supply.
