4S Ranch Water Reclamation Facility-CWEA 2022 Plant of the Year

Olivenhain Municipal Water District Marks Milestone Recycled Water Anniversary

/in , /by

Water recycling reduces the need to import or develop additional drinking water supplies. It is a vital water management strategy to ensure a safe, reliable, and locally controlled water supply to support healthy environments, robust economies, and high quality of life.

Water and wastewater agencies in San Diego County are developing or expanding their water recycling infrastructure. Among those at the forefront is the Olivenhain Municipal Water District. OMWD marks a significant milestone in August: the 20th anniversary of its award-winning 4S Ranch Water Reclamation Facility, which began serving high-quality recycled water for irrigation in August 2003.

OMWD annexed the 4S Ranch and Rancho Cielo Sanitation Districts from the County of San Diego in 1998. OMWD also took ownership of a small wastewater treatment facility in 4S Ranch. This facility had the capability to treat 0.25 million gallons per day (MGD) of wastewater from the surrounding commercial center and condominium complex. Treated wastewater was disposed of by spraying it on nearby unimproved pastures.

Recognizing the significant development plans for the 4S Ranch area, OMWD expanded the capacity of the facility to 2.0 MGD. As part of this expansion, OMWD also incorporated additional treatment phases of filtration and ultraviolet disinfection, improving water quality. OMWD required area developers to install the entire recycled water infrastructure for their planned communities.

Today, the facility produces over one million gallons of recycled water per day. It is delivered to irrigation customers in the southeastern portion of OMWD’s service area for use at HOA common areas, schools, parks, streetscapes, and golf courses. Together with recycled water purchased from nearby water and wastewater agencies to serve customers in portions of Encinitas and Carlsbad, OMWD now serves up to 15 percent of its customers’ total water demand with recycled water.

“For 20 years, OMWD has proudly served 4S Ranch and neighboring communities with high-quality recycled water, reducing the use of drinking water for irrigation,” said OMWD Vice President Matthew Hahn. “As California continues to face water supply challenges, the expansion of our recycled water system strengthens our water supply reliability and promotes sustainable water management.

Water recycling is the process of capturing and treating wastewater, for non-domestic purposes such as irrigation and industrial processes.

Water and wastewater agencies across San Diego County are developing or expanding their recycled water systems to reduce the need to import or develop other supplies.

Since 2003, OMWD has significantly increased its recycled water purchases through connections with neighboring agencies, including the City of San Diego, San Elijo Joint Powers Authority, Rancho Santa Fe Community Services District, and Vallecitos Water District. OMWD now serves over two and a half million gallons of recycled water every day. Each year, OMWD installs additional recycled water pipelines and converts more customers from potable water to recycled water.

By 2027, the volume of recycled water produced in the U.S. is projected to increase 37% from 4.8 billion gallons per day to 6.6 billion gallons per day, according to a recent survey by Bluefield Research.

OMWD leadership in developing water recycling

As a founding member of the North San Diego Water Reuse Coalition, OMWD works with nine northern San Diego County water and wastewater agencies across jurisdictional boundaries to reduce the impact of water supply shortages on San Diego County’s $268 billion economy. This regional approach has proven successful in developing local projects as well as obtaining $9 million in funding, significantly reducing the costs of water recycling projects for North San Diego County water ratepayers.

In addition, the Coalition has also secured federal funding of $23.8 million to help cover costs for water reclamation projects through 2025.

Expanding capacity for the future

As it looks forward to the next 20 years, OMWD continues to expand its recycled water capacity. It began construction this summer on three recycled water pipelines near Calle Barcelona in Carlsbad and in Village Park in Encinitas. Once complete, OMWD can convert up to 27 meters to recycled water, offsetting 12.7 million gallons of potable water used annually for irrigation.

OMWD has long pursued alternative water supplies like recycled water, a reliable, drought-proof approach for complementing existing water sources.

The San Diego County Water Authority has supported the development of recycling projects for decades, through membership in groups such as the WateReuse Association and collaborative efforts to promote local reuse efforts. Approximately 35,000 acre-feet of recycled water is beneficially reused within the Water Authority’s service area annually, and the volume is expected to continue growing as new and expanded plants come online.

California Seeks to Introduce Purified Wastewater to Drinking Supplies

/in , , /by /Spectrum News 1 by Jeremy Lindenfield

Earlier this summer, state water officials introduced draft regulations that, if passed, would allow purified wastewater to be directly introduced to drinking supplies.

Currently, purified wastewater has to be introduced to environmental buffers like groundwater aquifers before being added to drinking supplies, but the new regulations would allow treated water to bypass this step after undergoing additional purification processes.

Vista Irrigation District Celebrates 100 Years of Service

/in , /by

The Vista Irrigation District, one of the San Diego County Water Authority’s 24 member agencies, is celebrating its 100th anniversary.

In the 1920s, citrus and avocado farming in the Vista area increased so quickly that the growing region faced the real danger of running out of water. Completing the Henshaw Dam in 1923 made it possible for the Vista community to receive a reliable water source instead of relying on well water.

The arrival of the new water source sparked discussion about forming a water district to secure additional imported water to make continued growth possible. On August 28, 1923, voters approved the formation of the Vista Irrigation District (VID) in a landslide: 104 votes to four votes in a 100% voter turnout.

337 customers then, 134,000 customers now

In its first year, VID served 337 customers. Today, VID serves water to more than 134,000 customers in a diversified community and robust economy and is celebrating its 100th anniversary on August 28, 2023.

“Vista Irrigation District is proud of its accomplishments over the last century and looks forward to providing reliable water service to the residents and businesses it serves for years to come,” said Board President Jo MacKenzie.

Water builds new potential in Vista

The Vista community celebrated the arrival of the first water from Lake Henshaw on February 27, 1926. Following the arrival of water, crops of all kinds were planted in increasing numbers. The Vista area became known as the “Avocado Capital of the World,” with six avocado packing houses in the area.

In June 1946, after several years of negotiations, Vista Irrigation District purchased the San Diego County Water Company. Included in the purchase was the 43,000-acre Warner Ranch, a former Spanish Land Grant, which includes Henshaw Dam and Lake Henshaw. The deal was driven by the economic motivation to find another, less costly source of water for VID’s customers.

Drought conditions and population growth continued to press VID to seek additional sources of water. On February 16, 1954, the Vista Irrigation District became a member of the San Diego County Water Authority. It allowed VID to bring in water imported from the Colorado River and Northern California.

One year later, in 1955, Vista’s first suburban-style housing arrived in what had been an agricultural community. The Vista area began experiencing a decline in its avocado producing and packing due primarily to the industry’s economic decline and drought, which would continue into the 1960s. Many avocado groves were split into smaller parcels and sold to housing developers. The land was more valuable for homes.

A century of success

The people’s vote in 1923 revolutionized the small rural settlement held back by a lack of water. Over the years, Vista transformed itself from its agricultural origins to a thriving community with a diversified economic base and a revitalized downtown.

Vista Irrigation District has demonstrated its ability to adapt to these ever-changing landscapes over time and looks forward to many more successful years of service to the community. Through a century of service and stewardship, the Vista Irrigation District can take credit for its solid track record over the last century to continue many more successful years of service to the community.

(Editor’s note: The Vista Irrigation District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.

Opinion: Climate Change Will Undermine Quest by Fallbrook and Rainbow for Cheaper Water

/in , /by /Times of San Diego by Chris Jennewein Mentioned: San Diego County Water Authority

The long-running debate over whether the Fallbrook and Rainbow communities should leave the San Diego County Water Authority to obtain cheaper rates ignores a very large elephant in the room — climate change.

If the two rural communities cast their lot with Riverside County, their agricultural economy will depend upon the Colorado River and the State Water Project, both of which have been reeling from increasingly severe droughts.

States Have Started Negotiating New Rules to Keep the Colorado River From Crashing. Here’s What They Want

/in , , /by /CPR Newsby Michael Elizabeth Salas

The states that share the Colorado River need to negotiate new rules to better manage the dwindling river so it can continue to meet the needs of millions of people across the Southwest. That means finding ways to keep more water in the river and reservoirs, which means less water to go around.

The high-stakes, multi-year negotiation process between the states — Colorado, Utah, Wyoming and New Mexico in the upper basin and Arizona, Nevada and California in the lower basin — along with the U.S. Bureau of Reclamation, officially kicked off in June.

By the start of 2027, the states and the federal government are expected to have a new agreement on rules to manage the river so that Lake Mead and Lake Powell, the country’s largest reservoirs, don’t hit critically low levels. Climate change and overuse have stressed the river system and helped drive both reservoirs to drop to record-low water levels.

Reclamation Announces 2024 Operating Conditions for Lake Powell and Lake Mead

/in , , /by /Water News Networkby U.S. Bureau of Reclamation

The Bureau of Reclamation on August 15, released the Colorado River Basin August 2023 24-Month Study, which determines the tiers for the coordinated operation of Lake Powell and Lake Mead for 2024. These operating conditions, which are based on existing agreements under the 2007 guidelines and lower basin Drought Contingency Plans, will be in effect until the near-term guidelines from the Supplemental Environmental Impact Statement (SEIS) are finalized. Reclamation is currently analyzing the consensus-based Lower Division States proposed alternative for the SEIS.

Based on projections in the 24-Month Study, Lake Powell will operate in a Mid-Elevation Release Tier with a 7.48 million acre-feet release in water year 2024. Consistent with existing agreements, Lake Mead will operate in a Level 1 Shortage Condition – an improvement from the Level 2 Shortage Condition announced last year – with required shortages by Arizona and Nevada, coupled with Lower Basin Drought Contingency Plan water savings contributions. Mexico’s water delivery will be reduced consistent with Minute 323.

Western States Will Not Lose as Much Colorado River Water in 2024, Despite Long-Term Challenges

/in , /by /APby Suman Naishadham

Federal officials said Tuesday they will ease water cuts for Western states reliant on the Colorado River in 2024, thanks to a slightly improved outlook, but long-term challenges remain.

The river serves seven U.S. states, Native American tribes and two states in Mexico. It also supports a multibillion-dollar farm industry in the West and generates hydropower used across the region. Years of overuse by farms and cities, and the effects of drought worsened by climate change has meant much less water flows today through the Colorado River than in previous decades.

The U.S. government announces water availability for the coming year months in advance so that cities, farmers and others can plan. The first mandatory cuts that magnified the crisis on the river went into effect in 2022, followed by even deeper cuts this year due to drought, poor precipitation and less runoff from the headwaters in the Rocky Mountains.

Conservation measures and a wetter winter have improved the river’s health, leading to cuts being dialed back, starting in January. It won’t lead to dramatic changes because those affected have been living with water cuts for two years — or are voluntarily conserving water.
