A proactive approach to developing diversified water sources, including water recycling projects and conservation efforts, are helping the San Diego region weather the current drought. The Olivenhain Municipal Water District is working on multiple projects to expand the use of recycled water.
The San Francisco Bay Area is far behind Southern California in reusing water. Policy experts say it could take decades for the state’s second-most populous region to catch up — the lower half of the state recycled 83% more water than the Bay Area last year.
Standing outside Google’s Bay View campus in Mountain View in early August, wearing a pool-blue collared shirt and a gray blazer, California’s Natural Resources Secretary Wade Crowfoot pressed the state’s northern region to do more.
“If you spend time in Orange County, there’s a chance that you’re consuming purified water that’s been recycled,” he said. “We need to expand water recycling throughout the Bay Area.”

The Olivenhain Municipal Water District is working on multiple projects to expand the use of recycled water. The U.S. Bureau of Reclamation awarded the North San Diego Water Reuse Coalition, led by OMWD, $17.8 million in August for the development of recycled water infrastructure in North County.
Combined with the $6.1 million the federal agency granted to the coalition in 2021, up to $23.9 million will help cover costs for work performed on water reclamation and reuse projects through 2025. The coalition consists of nine water and wastewater agencies coordinating recycled water efforts across jurisdictional boundaries.
“Our board is proud to be a water district that consistently innovates to reduce project costs,” said OMWD Board Director Neal Meyers. “We constantly develop new funding partnerships, and we aggressively pursue grant funds to help build our vital infrastructure projects at the lowest possible cost to our ratepayers.”

The Regional Recycled Water Project will increase the capacity and connectivity of the recycled water storage and distribution systems of the coalition members and maximize reuse of available wastewater supplies.
To do this, the project will replace potable water uses with recycled water components, convert facilities to recycled water service, connect discrete recycled water systems to one another, increase recycled water storage capacity, and distribute recycled water to effectively meet recycled water demands.
Project objectives include optimizing available wastewater resources to help offset demands for imported potable water; proactively planning for facilities to meet demands for existing and planned growth in member service areas; combining resources and working together to maximize water reuse; and increasing water supply availability, reliability, and sustainability.
When all long-term project elements are completed, North San Diego County will gain approximately 41 million gallons per day of recycled water and potable reuse water.

Work began on OMWD’s Manchester Avenue Recycled Water Project in summer of 2022. As of October 1, more than half of the total 6,884 feet of recycled water pipeline has been installed. Once complete, irrigation customers connecting to the pipeline will reduce demand for imported potable water by more than 10 million gallons every year.

Snowpack in the Upper Colorado River Basin is more than double the average normally seen at this time of the year, according to the U.S. Bureau of Reclamation’s website.
A snapshot of the water situation shows above-average precipitation levels at five of the nine regions that make up the basin, and overall snowpack at 229% of average as of Oct. 24. Overall, precipitation is at 83% of average.
The Marin Water District has a new plan to deal with California’s worsening drought.
As of Oct. 24, Marin reservoirs have more water than normal, but the county said they’re not waiting for things to get worse.
Marin’s seven reservoirs hold 80,000 acre feet of water, the new plan would kick in when levels fall below 70,000 acre feet. The prior conservation plan didn’t go into effect until levels fell to 50,000.
Reports of low water levels at a few big hydropower plants in the West over the last few years have made it seem like hydropower is becoming less reliable. Last summer, officials in California were forced to shut down the Edward Hyatt Powerplant when water levels in Lake Oroville, the reservoir that feeds the plant, dropped below the intake pipes that send water into its turbines.
Assemblymember Eduardo Garcia and local tribes celebrate the passage of Safe and affordable drinking water for Native American tribes, also known as AB 2877. “One of the goals is to help prevent future situations like what occurred at oasis mobile home park but ensure tribal lands, specifically underserved tribal areas, can receive and be prioritized to receive state water infrastructure grants,” says An official from the office of Assemblymember Garcia’s office.
California regulators this week approved a $140 million desalination plant that could convert up to 5 million gallons of seawater each day into drinking water, as the state grapples with a persistent megadrought and plummeting water supplies.
The state’s Coastal Commission on Thursday voted 11-0 to approve the Doheny Ocean Desalination Project in Orange County in Southern California. The plant could be functioning within the next five years and supply water for thousands of people in the South Coast Water District.
Few places are more critical to the water supply in California than this immense northern reservoir in the foothills of the Cascade Range.
Fed by runoff from 14,163-foot Mount Shasta and other peaks, California’s largest reservoir opened in 1945 as part of the federal Central Valley Project, an elaborate system of man-made dams, pumps and aqueducts that aims to reduce flood risks and deliver water to farms and cities in the heart of the semiarid state.
About 15 miles north of Fresno sits Millerton Lake, a reservoir created in the 1930s when the U.S. Bureau of Reclamation built Friant Dam on the San Joaquin River. The dam provides irrigation water for fields and groves in much of the San Joaquin Valley, but it wiped out the Chinook salmon migration that had existed on the river for tens of thousands of years.
It also threatened the rights of landowners to divert naturally flowing San Joaquin River water for their fields. Instead of losing their rights, though, farmers who had land near the river agreed to trade their water to the federal dam project in exchange for “substitute water,” delivered to them from the Sacramento River.
