Southern California was in the midst of its fourth rain event of the season this week and with another expected next week, some experts believe the arrival of the weather phenomenon known as El Niño could be imminent. While it may be too early to link the Pacific storms to El Niño, the federal Climate Prediction Center’s El Niño “diagnostics discussion” could make the call next week on Dec. 13.
When residents in De Luz were forced to evacuate about 100 homes during the Rock Fire in July, an emergency generator installed by the Fallbrook Public Utility District proved its value by providing water to help firefighters extinguish the blaze.
The generator was installed about a year ago at the Donnil Pump Station at a cost of about $140,000. Since then, several fires have sparked in the hilly backcountry community north of Fallbrook.
The quick-burning Rock Fire broke out mid-afternoon on July 28 near Sandia Creek and Rock Mountain just south of the Riverside County line. The blaze grew quickly to 74 acres within two hours. Nearby residents were advised to evacuate, affecting about 100 homes.
San Diego Gas & Electric shut off the power for safety to 530 residents in the area at 4:12 p.m., according to information on the SDG&E outage website. The outage cut power to the pump station. FPUD kept water running thanks to the new generator, which is among several recent district projects and upgrades designed to maintain water service during emergencies.
The fire grew to 225 acres, but by 7:30 p.m. the forward spread was stopped. Power was restored gradually through the night, and the evacuation order was lifted the next morning.
Important community safeguard now in place
“Now, we can cover nearly all of the De Luz area during a power outage,” said FPUD General Manager Jack Bebee. “Fire has the potential to quickly spread, so this is a very important safeguard to have in place.”
The Donnil Pump Station conveys water from the San Diego County Water Authority’s aqueduct to the high-pressure zone in De Luz. The station was built before FPUD merged with De Luz Heights Municipal Water District in 1990, and it serves as the principal pump station in that area.
The pump station was upgraded as part of the district’s capital improvement plan. Without an emergency generator, water supply to the area could be cut off during a power outage. If that occurs during a wildfire, it could reduce flows for firefighters when they need it most to protect the community.
The San Diego County Water Authority’s Brought to You by Water outreach and education program made its debut on advertising monitors at Lindbergh Field the day before Thanksgiving – just in time for the busy holiday travel season.
Through the San Diego County Regional Airport Authority’s community promotion program, the ads are expected to remain in the rotation indefinitely, reminding travelers about the importance of water reliability to the region’s quality of life. The electronic display ads are visible in multiple spots throughout baggage claim areas in both Terminal 1 and Terminal 2.

The partnership between the Airport Authority and the Water Authority helps educate the region’s residents and visitors on the impact of something many take for granted – a safe and reliable water supply that sustains the region’s $220 billion economy and the quality of life of 3.3 million people.
The Water Authority is focusing on four core industries during the first phase of its Brought to You by Water program – manufacturing, tourism, agriculture and craft brewing. The initial airport ads highlight the craft beer industry, which has a $1.1 billion regional economic impact annually, and the tourism industry, which attracts 35 million visitors a year to the region.
Overall, access to reliable water supplies support $482 million per day in regional sales – the equivalent of nearly three Comic-Cons per day, according to a June report by the San Diego Regional Economic Development Corporation.
In addition to the airport ads, the Brought to You by Water program has included the creation of the Water News Network, the inaugural Water Innovation and Efficiency Award, a partnership with the hotel-motel industry to promote water-use efficiency by guests, participation in numerous community outreach events, and many other efforts designed to enhance appreciation for the region’s most precious natural resource.

When Water Authority crews began dewatering part of the region’s pipeline system for a 10-day shutdown in mid-November, they discovered a leaking valve that threatened to disrupt the time-sensitive operation.
At issue was a six-foot diameter valve in the Second Aqueduct that was designed to isolate a section of pipeline so workers could safely make repairs inside a dry section of the massive pipe. Instead, the valve was seeping water, which made it impossible to start the welding work slated for the relining project in Bonsall and Fallbrook.
The leaking valve was installed in 1980 and is at the end of its useful service life. While valve failure wasn’t an immediate threat, staff had to find a quick solution to avoid delays that could have impacted water deliveries to customers.
Each winter, the Water Authority coordinates with its 24 member agencies to schedule pipeline shutdowns when water demands are low so crews can conduct routine inspections and make repairs. Timing is always critical to ensure water agencies have adequate supplies while pipes are offline.

The leaking valve threatened to disrupt this year’s refurbishing plan, forcing the Operations and Maintenance Department to quickly assess several potential solutions, including using absorbent materials such as rice or oats to soak up excess water. The team quickly settled on a strategy to construct temporary dams inside the pipeline and divert the seepage while repairs were made.
First, crews built a dam with 200 sandbags just upstream of the leaking valve, redirecting water into another pipeline and away from the contractor’s workspace. Then, they constructed a secondary wooden dam to collect the trickle of water seeping past the sandbags.
The solution was successfully deployed in less than 48 hours, allowing the welding project to begin on time.
Encinitas, Calif. — Olivenhain Municipal Water District and Carlsbad Municipal Water District will host free workshops for local businesses and landscape professionals to promote the use and benefits of recycled water. The workshops will be held in Carlsbad on November 14 and in San Marcos on November 15.
Encinitas, Calif. — Olivenhain Municipal Water District’s Board of Directors selected Robert Kephart at its November 7 meeting as the new director representing Division 4 of OMWD’s service area. Mr. Kephart fills the seat left vacant by the resignation of Jerry Varty.
Mr. Kephart has 20 years of service on the County of San Diego Service Area 107 Fire Advisory Board and currently serves on the Rancho Santa Fe Fire Foundation board. A volunteer firefighter for the Elfin Forest/Harmony Grove Fire Department for 19 years, he achieved the rank of Captain and chaired the department’s facilities committee.
Whether you are excited about an extra hour of sleep or dour about losing an hour of sunlight at the end of the day, daylight saving time ends Sunday, Nov. 4. The annual adjustment is a great reminder to perform several important household tasks, such as replacing smoke alarm batteries and restocking emergency preparedness kits.
The San Diego County Water Authority asks residents to add one more important task when changing the clocks: Adjust irrigation systems to save water in the months ahead.
“Adjusting irrigation is an easy way to conserve water, since landscapes need less irrigation as the days get shorter and cooler,” said Dana Friehauf, a water resources manager for the Water Authority. “Residents also should make sure their irrigation systems are working correctly, and are free of broken sprinkler heads or other leaks that waste water.”
Approximately half of a typical California household’s water use is outdoors. Seasonal adjustments to irrigation controllers in preparation for winter weather not only reduce water waste, they benefit the health of landscape plants.
Additional water-saving practices during the fall and winter months include:
Fall is also the ideal time for residents to upgrade thirsty turf yards to WaterSmart sustainable landscapes. Homeowners can take advantage of winter rains to help establish a new landscape. The Water Authority’s award-winning WaterSmart Landscape Makeover Program offers a variety of free classes and how-to online videos to guide homeowners through the conversion process. More information is at WaterSmartSD.
In addition, there are a limited number of residential rebates available for homeowners who want to upgrade to sustainable landscaping at SoCal Water$mart.
The Water Authority offers additional water-saving resources for residents and businesses through its Live WaterSmart campaign. These include:

A $25.3 million Pipeline 5 relining project is under way in North County to improve the reliability of the San Diego region’s water delivery system. The project involves rehabilitating approximately 2.3 miles of one of the San Diego County Water Authority’s regional wholesale water pipelines in eight segments along a 9.5-mile stretch through the community of Fallbrook.
Construction work will be done in phases and completed in summer 2019. When finished, the Pipeline 5 Relining Project will help extend the service life of this vital piece of infrastructure for more than 75 years. Generally, relining construction rehabilitates segments of pipelines based on their age and the need for improvements.
Construction activities in Fallbrook began September 19 with the installation of protecting fencing, establishing an entrance to the construction area, and clearing the site of all vegetation and debris for safety. The relining itself will begin in November.
In broad terms, the relining process begins with dirt being excavated to create an access portal or work area. The construction crews will conduct most of the work underground, inside the pipe. They will access the pipe by excavating, establishing, and entering the pipeline through nine access sites, or portals. The portals will be 25-foot by 60-foot excavated pits, spaced approximately 525 to 2,500 feet apart. At each portal site, 40 feet of existing pipe is removed to permit access inside the pipe to install relining materials.
The work involves removing 20-foot sections of old concrete pipe at each portals. Then, new steel liners are inserted into the existing pipe using a specialized pipe cart. Liners are installed into the entire pipe section. Once installed, the joints of the liner pipe are welded together. Each new steel liner is coated with a cement mortar lining. Finally, portals are backfilled and — after pipeline disinfection — the pipe is ready to be put back into service.
Much of the construction work associated with the project is in Water Authority rights-of-way. Some portals within the unincorporated San Diego County portion of the alignment will be in undeveloped areas.
As people living and working in the area begin to see the activity, project team members will be available to address questions or concerns. Contact information including 24-hour phone numbers, email contacts, and website links are posted on nine informational signs along the construction route. Construction workers on site will also have contact information to pass out on request.
For more information, residents can call the 24-hour project information line at (877) 682-9283, ext. 7009 or email . A representative from the project team will respond within one business day.
The Water Authority’s large-diameter pipelines extend approximately 310 miles to convey water throughout western San Diego County. Approximately 82 miles of these pipelines were installed between the early 1960s and late 1980s with pre-stressed concrete cylinder pipes, or PCCP, made from a combination of steel and concrete. First used during World War II to help minimize the use of precious steel, this pipeline type is used extensively around the world.
Numerous failures of similar pipes nationwide prompted the Water Authority to take proactive measures to reinforce its PCCP type pipelines with steel liners in an strategic, multi-decade program starting in 1991.
In addition, in 2003 the Water Authority started using an innovative carbon fiber technology to conduct urgent pipeline repairs, helping ensure a safe and reliable water supply to the region.
When the Fallbrook project is finished, the Water Authority will have rehabilitated approximately 47 miles of PCCP — more than half of the total in the Water Authority system.
San Diego County Water Authority Board Chair Jim Madaffer today sent a letter to the Metropolitan Water District of Southern California’s Board of Directors that lays out a potential compromise approach by both parties designed to end nearly a decade of litigation over MWD’s rates.
The letter includes specific, practical terms that respect both the Water Authority’s and MWD’s perspectives towards an equitable conclusion in coming weeks.
“Concluding all pending court cases is in the best interest of everyone involved, and it would allow us to begin a new era of collaboration on other important regional and state issues,” said Madaffer, who started his tenure as chair on Oct. 1. “I hope MWD will embrace this gesture of good faith to seek settlement, and that we can do so in an expeditious and fair manner.”
Madaffer’s letter builds on the commitment of his predecessor, prior Water Authority Board Chair Mark Muir, to seek an end to lawsuits that started in 2010 and involve billions of dollars of contested rates and charges.
The Water Authority won several significant items in two cases covering MWD’s rates for 2011-2014, including additional rights to approximately 100,000 acre-feet a year of MWD water, invalidation of an illegal contract clause that MWD used to deny support for local supply development projects, and damages and interest on tens of millions of dollars of unlawful Water Stewardship Rate charges by MWD. The courts allowed MWD to continue charging historic State Water Project costs in water transportation rates charged to the Water Authority.
Background
More than 20 years ago, the Water Authority and its member agencies began improving the San Diego region’s water supply reliability by lessening reliance on MWD, which at the time supplied about 95 percent of all the water used in San Diego County.
The cornerstone of that diversification strategy is a set of agreements known collectively as the Colorado River Quantification Settlement Agreement, which was signed in 2003 to secure independent water supplies for the Water Authority from the Colorado River. To deliver these supplies to San Diego County, the Water Authority must use pipelines operated by MWD because MWD owns the only large-scale conveyance facilities in Southern California for transporting water.
The Water Authority filed suit in 2010 seeking to invalidate MWD’s rates, and then filed additional suits in 2012, 2014, 2016 and 2018 because MWD kept adopting rates using the same methodology and flawed cost allocations. A series of court decisions have been issued in the 2010 and 2012 cases. The other cases have been stayed in Superior Court during the appellate process on the initial two lawsuits.
Spring Valley, Calif. – On Oct. 11, the Otay Water District executed a successful bond sale that is expected to close on or about Nov. 1. The water revenue bond will fund $28 million of District’s capital projects during the next three years and will refinance $6.9 million of the District’s 1996 Variable Rate Demand Certificates of Participation (COPs) to a fixed rate of interest. By refinancing its 1996 Variable Rate COPs to a fixed rate, the District has eliminated the risk of increasing costs for customers due to rising interest rates.
