Higher utility rates will be here starting on Jan. 1. NBC 7 has already talked about higher energy rates, but water and wastewater rates are rising too. That means higher utility bills are on the way for many San Diegans. But just how much are they going up? Some, like water and wastewater increases, are set in stone, while others are being modified right up to the last minute. That can make it hard for families to plan.
Four years ago, when the San Diego City Council approved paying tens of millions of dollars to relocate utility pipes and other equipment to make room for the ambitious Pure Water project, city officials insisted they would recover the money from San Diego Gas & Electric. That didn’t happen. The city sued San Diego Gas & Electric in 2020, saying that the company violated its franchise agreement by refusing to pay to move its equipment.
The Helix Water District has expanded its ongoing sustainability efforts with the addition of its first all-electric, zero-emission, Ford F-150 Lightning pickup truck.
“Converting public and private fleets to zero-emission trucks is a big part of the governor’s plan to have five million zero-emission vehicles in California by 2030,” said Helix Water District Director of Operations Kevin D. Miller. “This is a small step, but Helix is heading in the right direction.”

The district dispatches 80 light- and heavy-duty trucks throughout its 50-square-mile service area daily to maintain the district’s pipelines, pump stations, and reservoir tanks, and also in response to customer calls. Field operations crews drive up to 100 miles per day.
The Ford F-150 Lightning has over a 200-mile range. Ordering the vehicle prior to recent manufacturer price increases and taking advantage of rebates offset the price difference between the electric and gas-powered models. Electric trucks are also anticipated to save maintenance costs due to fewer moving parts to replace than comparable internal combustion engine models.
Avoiding fuel costs generates more savings. The district’s light-duty gasoline trucks have a fuel efficiency of about 20 miles to the gallon and cost 25 cents per mile to drive. Thanks to the district’s power purchase agreements and other investments, the electric trucks will cost less than 10 cents per mile.

Helix began transitioning to a sustainable fleet in 2017 when it replaced inefficient light-duty work trucks with seven Toyota Prius plug-in hybrids. The hybrids are 400% more fuel efficient than the trucks they replaced. The district also partnered with SDG&E and received grant funding to install on-site charging stations at two of its facilities.
“We welcome our first fully electric work vehicle,” said Helix Water District Board President Kathleen Coates Hedberg. “The technology has come a very long way, and zero-emission trucks benefit the cities and communities we serve by reducing operational costs, improving air quality, and reducing our environmental footprint. Whether developing new water sources or advancing toward a cleaner fleet, I am proud of the district’s sustainability efforts.”
In 2020, the district switched from diesel to renewable diesel, resulting in decreased emissions, particulates, and a noticeable increase in vehicle performance.
Additional sustainability efforts include:
Each of these programs reduces energy use and reduces costs, which helps reduce operational costs for Helix Water District customers.

The hottest days this summer pushed California’s power grid to its limit. People were asked multiple days to conserve energy to avoid rolling blackouts.
The San Diego County Water Authority’s water-energy partnership with San Diego Gas & Electric is seeking $1.8 million in additional funding through 2026 to continue saving water and energy for thousands of income-qualified residents across the San Diego region.
For more than 25 years, the Water Authority’s Water-Energy Nexus Program, or WEN, has maximized energy savings while supporting water efficiency in the San Diego region. SDG&E and the Water Authority have worked together to trim water and energy use and costs in one of the longest-running partnerships of its kind in California. As part of its role, the Water Authority funds the installation of water efficiency devices for eligible customers and communities.

Toilets account for nearly 30% of a typical home’s indoor water use. The WEN Program increased water efficiency by replacing inefficient fixtures with state-of-the-art water-saving devices in disadvantaged communities.
“The Water Authority is committed to helping the San Diego region make the most of our water supplies through a variety of innovative programs,” said Kelley Gage, director of the Water Resources Department at the Water Authority. “Through our partnership with SDG&E, we extend help to families that might not be able to afford these environmentally friendly upgrades without support.”
SDG&E’s Energy Savings Assistance Program installs both water- and energy-saving measures in single-family, multifamily, and manufactured homes. The Water Authority reimburses SDG&E for water-saving devices installed by its contractor, Synergy Companies. This partnership has received funding to continue through 2025.
Installation of high-efficiency toilets and irrigation controllers is a collaboration with SDG&E’s Multifamily and Manufactured Housing Programs, which was recently approved for four more years of funding.

Low-income residents are sometimes unable to participate in water and energy conservation programs due to the upfront costs. The Water Authority’s program invests in water-efficient upgrades upfront. Adding funding capacity for additional retrofitting will help meet long-term conservation goals.

The head of California’s electric grid said Wednesday he is “guardedly optimistic” that the state will avoid rotating blackouts this summer, but warned that voluntary cooperation during Flex Alerts will be necessary.
Elliot Mainzer, president and CEO of the California Independent System Operator, said utilities throughout the state have built up power reserves and invested in new technology like battery storage to prevent blackouts like the ones in 2020.
But recent record heat in California and the Pacific Northwest combined with a drought that will reduce hydropower give him cause for concern.
The San Marcos Interceptor Replacement Project remains on schedule, with Phases 1 and 1A completed according to the Vallecitos Water District. The project replaces the District’s 1960s era 21-inch diameter sewer interceptor with more than 12,000-feet of 42-inch diameter sewer pipeline between Twin Oaks Valley Road and Pacific Street.
The Interceptor is a large trunk sewer pipeline receiving and conveying wastewater by gravity to the Encina Wastewater Authority. In Phases 1 and 1A of the project between 2002 and 2014, portions behind the Creekside Marketplace from State Route 78 to Grand Avenue, from Twin Oaks Valley Road to east of Johnston Lane, from Grand Avenue to Via Vera Cruz, and east of Johnson Lane to the south side of State Route 78 were completed.
Phase 2 will complete the remaining 3,400-feet of the westernmost project corridor extending from Via Vera Cruz to Pacific Street. The project budget is $8.5 million. The completion of Phase 2 of the Interceptor project has been in the works for more than 30 years, with the project exchanging numerous hands in planning, design, and construction.
“This is a milestone project for the District both in size and significance,” said Ryan Morgan, capital facilities senior engineer.
Microtunneling made it possible for the Vallecitos Water District to successfully complete the project in under a week with no damage to the existing utilities while also minimizing traffic impacts at San Marcos Boulevard and Pacific Street. Photo: Vallecitos Water District
The project used state-of-the-art trenchless technology to install a 115-ft long tunnel under an existing concrete culvert under the Pacific Street and San Marcos Boulevard intersection. The 42-inch diameter fiberglass reinforced plastic Interceptor sewer was installed inside a 60-inch diameter steel casing pipe.
Using a process known as “microtunneling,” contractor TC Construction and sub-consultant JW Fowler used a MicroTunnel Boring Machine (MTBM) inside an excavation in the eastbound lanes of San Marcos Boulevard and be received in a smaller excavation in the westbound lanes of San Marcos Boulevard at Pacific Street.
The MTBM is larger than 60-inches in diameter to be large enough to bore through native soils, rock, and backfill along the Interceptor alignment. The new tunnel’s wall is pressurized internally using hydraulic fluids before the steel casing is permanently installed. The MTBM is remote-controlled by an operator on the surface and is laser-guided to ensure it stays within the designed horizontal and vertical alignment (line and grade).
The MTBM’s high level of accuracy makes it especially useful when a project needs to avoid conflicts with existing underground utility lines, including a 16-inch diameter high-pressure San Diego Gas & Electric gas line in this project. The microtunnel installation was a 24-hour, 7-day-a-week process.
The microtunnel allowed the District to “thread the needle,” and the tunnel was completed in under a week (plus setup). There was no damage to any of the existing utilities in San Marcos Boulevard, and traffic impacts were minimized.

The Interceptor project required biological monitors and archeological monitors for work adjacent to San Marcos Creek or predetermined environmental sensitive areas. Special mitigation measures and biological monitoring were required for construction during bird nesting season between February 15 and September 15. Additionally, tribal paleological monitors from Native American tribes of significance in the area were represented during excavation work in the creek.
The final leg of the project will begin in the easements adjacent to the creek between Via Vera Cruz and McMahr. Construction completion is expected in June 2021.
This replacement project was originally identified in the District’s 1991 Master Plan and has been phased to be completed prior to City of San Marcos development of the Creek District.

San Diego Community Power (SDCP), the local government agency created to speed up the transition to renewable energy, will officially start serving its first customers in less than two weeks.
The launch is the culmination of years of debate over whether governments can be trusted to purchase electricity on behalf of homes and businesses, or if that responsibility should stay with San Diego Gas & Electric, the region’s private utility.
A battery storage demonstration project already providing a carbon-free source of electricity to California’s grid is about to be tested to see how well it can work on microgrids.
Located on a bluff at a San Diego Gas & Electric substation in Bonita, the energy storage project uses vanadium redox flow battery technology that stores electricity when the grid has excess supply and then discharges the energy when the power system needs it.
San Diego Gas & Electric will utilize 600 additional radios as part of the Regional Communications System.
A 5-0 San Diego County Board of Supervisors vote December 8 authorized the execution of an agreement to add the radios for SDG&E, which will pay the county an estimated $5,086,620 for the additional participation, and authorized the county Sheriff to execute amendments, extensions, or revisions which do not materially impact the program or funding level.
