The Lakes is a community in Rancho Santa Fe that will include 387 homes, large outdoor natural spaces, and several lakes, when fully developed.
This phase included the installation of four new water meters that will measure an anticipated savings of over nine million gallons of imported drinking water each year. As the entire state continues to face water supply challenges, converting customers to recycled water for irrigation strengthens the local water supply portfolio, reduces treated wastewater flows to the ocean, and reduces the region’s overall demand for imported water.
“OMWD has been proactive about converting customers to recycled water for irrigation for decades,” said OMWD board director Marco San Antonio. “Every customer converted supports the goal of reducing our reliance on imported water, and this conversion is yet another step towards fulfilling that goal.”

OMWD produces up to two million gallons of recycled water everyday at its 4S Ranch Water Reclamation Facility. Additionally, OMWD is the lead agency of the North San Diego Water Reuse Coalition, a group of nine North County agencies that coordinate across jurisdictional boundaries to share resources and expand the reach of the recycled water distribution system. As a result of their proactive approach, OMWD now serves up to 15 percent of its overall demand from recycled water and continues to identify additional ways to make recycled water available to eligible customers.
(Editor’s Note: Olivenhain Municipal Water District is a public agency providing water, wastewater services, recycled water, hydroelectricity, and operation of Elfin Forest Recreational Reserve. Organized in 1959, OMWD currently serves approximately 87,000 customers over 48 square miles in northern San Diego County, and is one of the San Diego County Water Authority’s 24 member agencies).
Chula Vista, Calif. – Eight local high school students were honored for their award-winning photographs at the Sweetwater Authority Board Meeting on April 26. The winners were selected from a group of 62 students from high schools across the South Bay who submitted 148 entries for the Authority’s High School Photo Contest.
“The Board is proud to support this annual contest, and looks forward to seeing the entries and continued involvement from our local high school community,” said Board Chair Hector Martinez. “We are continually amazed by the talent and photography skills of students in our service area and we encourage residents to go to see the photos at the Bonita Museum and Historical Society.”
A federal report released April 20 says near-record snowpack in the Colorado River Basin could raise the elevation of Lake Mead by more than 20 feet by the end of the year, providing a critical opportunity for water agencies to improve long-term management of the river.
The U.S. Bureau of Reclamation’s report shows vastly improved hydrological conditions are also expected to raise the water level in Lake Powell by more than 50 feet. California relies heavily on lakes Powell and Mead for water, as do Arizona and Nevada.
Despite the good news this year, the ongoing trend toward a hotter and drier climate means long-term solutions remain critical. About two-thirds of San Diego County’s supplies are conserved Colorado River water.
The San Diego County Water Authority supports a consensus-based approach for long-term solutions that uphold California’s high-priority water rights on the Colorado River.
“The report is definitely welcome news and will buy us time to make crucial decisions,” said Dan Denham, the Water Authority’s deputy general manager. “It’s critical that everyone with a stake in the river – including the Bureau of Reclamation, basin states, tribes and Mexico – continue to develop real and lasting solutions for the river’s long-term operation.”
In its annual “24-Month Study,” Reclamation addresses changing conditions on the Colorado River and forecasts operations for the river system’s reservoirs for the following two years. Today’s report projects the above-average snowpack will help recharge the Colorado River. Up to 9.5 million acre-feet of water is expected to be released this year from Glen Canyon Dam into Lake Mead, an increase of 2.5 million acre-feet. That water could increase Lake Mead’s water level by more than 20 feet and break years of declines in the reservoir’s levels. Actual water releases into Lake Mead will be adjusted based on the observed inflow in Lake Powell.
The study follows Reclamation’s April 11 release of a draft Supplemental Environmental Impact Statement that considers changes to near-term operations on the Colorado River, including potential reductions in water supplies for California and across the Lower Colorado River Basin. The draft analyzes two alternatives, plus a no-action alternative.
“Despite this year’s welcomed snow, the Colorado River system remains at risk from the ongoing impacts of the climate crisis,” said Commissioner Camille Calimlim Touton.

The Water Authority continues to collaborate with its partners on the Colorado River Board of California to ensure the state’s high-priority water rights on the river are upheld through the environmental review process.
“We are hopeful that Reclamation’s flow projections will materialize as expected,” Denham said. “At the same time, the Colorado River remains mired in decades of hot, dry weather that requires new thinking about water use and conservation across the Basin. As we work collaboratively to find consensus-based, long-term solutions that serve all water users, we will continue to advocate that any future actions uphold the Law of the River and California’s senior rights.”

A recent upgrade to a Helix Water District treatment plant saved money for its ratepayers while ensuring a continued supply of high quality drinking water.
After 20 years of service, the ozone disinfection system at the R.M. Levy Water Treatment Plant needed an upgrade. The projected cost of outsourcing the work needed came to $3.5 million. Instead, Helix staff at the plant proposed doing the work themselves – and they did – saving an estimated 70% after the work was completed for $1.1 million.
“With infrastructure projects, we always start with two questions,” said Helix Water District General Manager Brian Olney. “Do we replace it or can we rehabilitate it? And, is it better to outsource the work or do it in-house? These two questions saved our customers millions of dollars this year and are a good example of how we continuously look for ways to save our customers money.”

Water treatment is a multi-step process. First, organic material suspended in the water is removed. Water is then disinfected to remove or inactivate harmful microscopic organisms. Finally, the water is filtered.
Chlorine is the most widely used disinfectant at conventional water treatment plants. The Helix Water District uses ozone as its primary disinfectant, supplemented with chlorine. Ozone inactivates a wide range of microorganisms, needs little contact time with the water, and it eliminates most of the odor and taste issues some people associate with tap water. This mix maintains the quality of the water while it makes its way through the water distribution system.
The treatment plant uses an ozone generator, which produces ozone by applying high amounts of electricity to oxygen gas. The oxygen molecules (O2) split and regroup as ozone (O3). The ozone gas then bubbles up through the water to inactivate any microorganisms present.
Helix maintenance staff worked closely with the manufacturer of its original ozone system installed in 2002. The same manufacturer supplied new hardware and electrical components required for the upgrade. The ozone disinfection system includes the gas feed systems, generators, power supply units, and the instrumentation hardware and software controlling the system.
The project began with a proof-of-concept pilot project two years ago. Once the methods were tested, each of the three ozone generators was upgraded with the new technology, then tested and commissioned.
In addition to the 70% estimated cost savings from the upgrade project, the improved efficiencies of the ozone generators will produce long-term cost savings.
The ozone generators and their power supply units are now fully upgraded thanks to the efforts of the Helix team. The last phase of the project is the replacement of the computer control system, which is scheduled for 2024.
(Editor’s Note: The Helix Water District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the San Diego region.)
The San Diego County Water Authority’s Pipeline 5 will be returned to full service after five months of rehabilitation work that runs from April 16 through April 25. The work is necessary to extend the useful life of critical water infrastructure that delivers reliable supplies for the region.
The Water Authority and its member agencies are coordinating to minimize impacts to residents and businesses, while servicing pipelines that are more than 65 years old.
