In a report sponsored by the California Water Impact Network, policy expert Max Gomberg revealed that the continued funding of the controversial Delta Tunnel – also known as the Delta Conveyance Project – could bankrupt the powerful Metropolitan Water District of Southern California. Gomberg is the former climate change and water conservation manager for the State Water Resources Control Board.
Gov. Gavin Newsom and his administration have touted plans to build a tunnel to transport water beneath the Sacramento-San Joaquin River Delta, saying the project would modernize California’s water infrastructure and help the state adapt to climate change.
But an advocacy group is urging the Metropolitan Water District of Southern California to abandon the $16-billion project, saying it doesn’t make financial sense for the state’s largest urban water agency.
A joint venture of AECOM and Brown and Caldwell (AECOM-BC Team) has been chosen to provide program and project management support and engineering design services for the Pure Water Southern California program, one of the largest water reuse programs in the world.
Forecasts of a hotter, drier climate for the Southwest U.S. make every effort to save water critical. A new program now available intends to do just that for residents in parts of Southern California. The San Diego County Water Authority, in collaboration with the Metropolitan Water District of Southern California, are offering free indoor and outdoor residential water efficiency use surveys.
Forecasts of a hotter, drier climate for the Southwest U.S. make every effort to save water critical. A new program now available intends to do just that for residents in parts of Southern California. The San Diego County Water Authority, in collaboration with the Metropolitan Water District of Southern California, are offering free indoor and outdoor residential water efficiency use surveys.
The surveys, in-person and virtual, are available within MWD’s service area, including San Diego County.
“The survey is a free, easy, tool that can show you what small changes can be made which will lead to long-term savings,” said Joni German, a water resource specialist at the Water Authority.
She said the surveys are scheduled on a first-come, first-serve basis. After filling out an online application the next step is scheduling a visit from a certified landscape auditor.
Not only do residents save our most precious resource, they also save money.
Vallecitos Water District customer Michael Berry took advantage of the program because he wanted to do more to save water. Even though Berry had previously replaced his grass with artificial turf, he said he learned how to save even more water after the survey.
“What I learned primarily is how to improve my irrigation system from spray-based systems to a drip based system,” said Berry. “That’s the primary thing I’ll fix going forward.”
An outdoor survey includes an evaluation of the water meter to check for leaks along with zone information on the homeowner’s plants. During this process the homeowner will take the surveyor around areas with irrigation, divided into sections or “zones.”
Inspections will be done on each zone to determine whether the current irrigation system in place is operating at peak efficiency. The water meter can be utilized in seeing any unusual increase of water usage without the homeowner’s knowledge which would indicate a leak in the irrigation system.
In Berry’s case, the surveyor performed a check up on potential irrigation problems such as valve malfunctions, pressure, sprinkler alignment, drainage leaks and anything else that might reduce efficiency or indicate overwatering. The presence of leaks or blocks in the valves and using spray water instead of drip irrigation are just a few elements the surveyor warned Barry could negatively impact his water savings.
“One of the specific things that the surveyor helped me with was the valve maintenance, making sure that every 6-12 months you have to clean the valves out to make sure they’re not getting impeded,” Berry said.
Once the survey is completed, participants receive a written report along with irrigation efficiency recommendations, and information on financial incentives to offset the cost of recommended improvements.
“It’s a good way to get a new perspective for anyone who does their own landscaping work and is curious about their water usage,” Berry said. In his case, Berry was able to make a plan to improve the water saving practices he already has in place.
“Spray system is where most of the problem I need to solve exists,” he said. “The spray system I have was spraying a lot of dirt areas which aren’t really helping the plants and tree. The second problem is the system is hard to control in terms of the amount of water that I want to put on over a period of time.”
Water efficiency inspections can also be performed on larger commercial landscapes. Schedule your free survey here: www.waterefficiencysurvey.com/.

Fast action by the San Diego County Water Authority and its partners is helping maintain water service in Tijuana after problems with the city’s aqueduct emerged in December.
Emergency water deliveries started last week after a coordinated effort between the Water Authority, Otay Water District, and Metropolitan Water District of Southern California (MWD). The typical multi-month approval process was compressed into a few days to avoid additional water supply shortages in Tijuana.
“We’re extremely proud of how quickly the Water Authority staff worked to meet the emergency water needs of our neighbors to the south,” said Mel Katz, Water Authority Board Chair. “Coordinating with multiple agencies and getting the necessary approvals in just three days was a team effort and is a credit to the Water Resources and Operations & Maintenance departments.”
Cross-border emergency deliveries started more than 50 years ago and are governed by an agreement between the United States and Mexico to provide Tijuana with a portion of Mexico’s Colorado River supply. The Water Authority provides emergency water deliveries to Mexico through a cross-border connection in Otay Mesa. These deliveries use Water Authority, Otay Water District, and MWD facilities to transport the emergency supplies from the Colorado River to Mexico, which pays transportation costs on deliveries to Tijuana and provides funds for meter connection upkeep. Deliveries are typically planned months in advance due to the number of government agencies involved.
On January 2, the Water Authority received a request for emergency water delivery to Tijuana. Water Authority staff immediately expedited the complex approval process during this unplanned Tijuana aqueduct outage. Those steps included working with the U.S. International Boundary & Water Commission, Otay Water District, and MWD to confirm system capacity availability and establish costs associated with the additional emergency deliveries.
The current water deliveries are scheduled to continue until the end of February. Consistent with the previously approved schedule, planned water deliveries will restart in April and continue through September 2023.

Six San Diego County student artists are among the 37 Southern California students whose artwork will appear in the 2023 “Water Is Life” Student Art Calendar.
As California faces the prospect of a fourth consecutive dry year, officials with the Metropolitan Water District of Southern California have declared a regional drought emergency and called on water agencies to immediately reduce their use of all imported supplies.
The decision from MWD’s board came about eight months after officials declared a similar emergency for 7 million people who are dependent on supplies from the State Water Project, a vast network of reservoirs, canals and dams that convey water from Northern California. Residents reliant on California’s other major supply — the Colorado River — had not been included in that emergency declaration.
Brown and Caldwell, an engineering and construction services firm, announced that it has been hired by the Metropolitan Water District of Southern California to design a sectional replacement of a critical Southern California water supply pipeline, the Rialto Pipeline. The Rialto Pipeline, constructed in 1972, is approximately 30 miles long with a diameter ranging from 96 inches to 144 inches.
Rincon del Diablo Municipal Water District reports that it completed an initiative to provide nearly $1.2 million in rebates to customers and has received overwhelmingly positive feedback about the program.
