Vista Irrigation District’s Consumer Confidence Report, also known as the annual water quality report, is available to be viewed online. English and Spanish versions of the report are available for download from the district’s website.
In 2024, as in past years, the district’s tap water met all federal and state safe drinking water standards.
The Helix Water District’s new 2024 Water Quality Report shows that throughout 2024, the district continued to deliver healthy, top-quality drinking water, which was 100% compliant with federal and state standards.
The characteristics of each specific local water supply depend on its original source and the route it travels through rock, soil, lakes, and rivers. Helix WD manages the characteristics of each water source through its multi-step treatment process.
In 2024, 58% of the Helix Water District’s supply came from the Colorado River, 25% came from Lake Cuyamaca and creeks in the mountains east of San Diego, and 17% came from Northern California through the State Water Project.
All raw water, whether imported or local, is treated before entering the Helix Water District distribution system. In 2024, 87.8% of the District’s water was treated at Helix Water District’s R.M. Levy Water Treatment Plant in Lakeside.
The remaining 12.2% of water was purchased through the San Diego County Water Authority and treated at the Metropolitan Water District of Southern California’s R.A. Skinner Treatment Plant, the Water Authority’s Twin Oaks Valley Water Treatment Plant, and/or the Claude “Bud” Lewis Carlsbad Desalination Plant.

Federally regulated under the Safe Drinking Water Act, public water systems are monitored for contaminants, including microbial threats, chemical hazards, or disinfection byproducts. All water and wastewater systems are regularly tested to ensure quality.
Each day of the year, state-certified staff at the Helix Water District conduct hands-on testing in the field and in its lab. Over 200 water samples are collected and analyzed every 24 hours to ensure its drinking water meets all safety standards. Water quality testing continuously monitors the treatment process, 24 hours a day, seven days a week.
“I wish all of our customers could meet our treatment staff,” said Helix General Manager Brian Olney. “Their expertise and experience goes into every drop of water we produce. They are at the forefront of the water industry and are committed to keeping the communities we serve healthy and happy.”
The 2024 Water Quality Report explains the water quality standards mandated by the U.S. Environmental Protection Agency and the State of California, and presents Helix’s water quality data for each standard. As in years past, Helix’s tap water outperformed all standards.
The Helix Water District’s 2024 Water Quality Report is available online in both English and Spanish.

National Hydration Day is June 23, a time to recognize the essential role of one of humanity’s resources: safe, reliable drinking water.
National Hydration Day was originally established in 1991 at the start of the summer season to remind athletes of the importance of hydration and to promote the benefits of proper hydration for overall health.
It also demonstrates the availability of the healthiest way to stay hydrated: the drinking water provided by water agencies like the 22 member agencies of the San Diego County Water Authority.

Water makes up 50 to 70% of the healthy human body weight. It lubricates joints, regulates your body temperature, flushes toxins via urine and sweat, and supports every organ system from brain function to heart health.
Scientific studies underline hydration’s importance. Proper hydration supports cognitive performance, mood stability, and may slow age-related cellular decline.
The American Heart Association recommends that men drink about fifteen and a half cups of water and women drink about eleven and a half cups of water each day. Older adults should pay extra attention to hydration needs to prevent rapid fluid loss from decreased total body water or medication effects .
Water and water-rich foods are the best sources of hydration to keep your heart healthy and maintain a regulated temperature. Relying on sodas, sports drinks, or sweetened coffee and frozen drinks to stay hydrated can introduce too much sugar into your diet.

On National Hydration Day — and every day — the mission of the San Diego County Water Authority and its 22 member agencies is to ensure that every tap delivers water that meets or exceeds federal and state standards.
Federally regulated under the Safe Drinking Water Act, public water systems are monitored for contaminants, including microbial threats, chemical hazards, or disinfection byproducts. All water and wastewater systems are regularly tested to ensure quality on a regular basis.
The delivery of safe water to the Water Authority’s 22 member agencies and their customers is the top priority for the Water Authority. Regular water quality monitoring and the use of online monitoring equipment ensure that the Water Authority is delivering high-quality, safe water to its member agencies 24 hours a day, seven days a week.
Potable water supplied by the Water Authority to its member agencies comes from three primary sources. Whether the water is treated by the Metropolitan Water District, the Water Authority, or a local agency, all treated water served in San Diego County meets or exceeds rigorous state and federal water quality standards.
Each member water agency publishes an annual Water Quality Report, such as this example from the City of San Diego, and from the Padre Dam Municipal Water District, which provide details about treatment and compliance.

You can use National Hydration Day as a reminder to check your own hydration habits.
Make water your primary source of hydration. Fill your reuseable bottle with tap water and put it into your refrigerator at night so it’s ready and waiting for you in the morning.
Choosing tap water over bottled beverages is eco‑friendly, budget‑friendly, and health‑friendly. Public water systems are strictly regulated, while bottled water is less so. Reusable bottles reduce plastic waste. Save money and save the environment by using tap water.
If your taste buds need more variety than plain water, add lemon, cucumber, or mint to your reusable drinking water bottle. National flavoring can help you ensure you reach your daily hydration goals.
Learn the signs of dehydration from experts such as the Mayo Clinic, which can show up quickly during hot summer days, especially if you are outside and active. It is especially dangerous for infants, children, and older adults.

Investments by the San Diego County Water Authority and its member agencies in treatment plants, pipeline maintenance, and highly trained water professionals at all levels ensure safe, reliable water is available to support your health on National Hydration Day and every day.
Construction is complete on new recycled water pipelines by the Olivenhain Municipal Water District (OMWD) in Carlsbad and Encinitas, resulting in significant annual drinking water savings.
The installation of over 5,600 feet of new pipelines will allow several HOA communities in the project area to convert their irrigation systems to recycled water, resulting in more than 12.5 million gallons of drinking water saved annually.
“Converting our irrigation system to recycled water was the right decision,” said Paul Heller, Summerhill HOA board president. “We’ll be less impacted by future droughts that could limit watering schedules, and recycled water is more affordable than drinking water, which will reduce costs for our residents.”

OMWD secured more than $900,000 in grant funding to make the project cost-effective for ratepayers. Grants from the U.S. Bureau of Reclamation’s Title XVI Water Reclamation and Reuse Program and the California Department of Water Resources’ Integrated Regional Water Management Program contributed funds to offset project costs.
“Converting our commercial customers to recycled water for irrigation will help ease our dependence on imported water,” said OMWD board secretary Christy Guerin. “And by using grant funds to help with the costs involved, we’re minimizing the impacts to ratepayers.”
The project was completed on time and with no interruptions to customers’ water supplies.
Recycled water is locally produced, disinfected wastewater that is used for irrigation purposes. OMWD meets up to 15 percent of its overall demand with recycled water and continues to identify additional ways to make recycled water available to eligible customers.

One hundred percent of OMWD’s drinking water supply is imported into the region. These sources are threatened by droughts and overuse.
Recycled water is locally produced, disinfected wastewater that is used for irrigation. Not only is it a drought-resilient supply, but recycled water also costs less than potable water. In addition, using recycled water reduces the amount of treated wastewater discharged into the ocean and reduces the dependence on imported water from distant sources.
The completion of the pipeline extensions will result in the conversion of 28 water meters from potable to recycled water, allowing large customers in Carlsbad and Encinitas, such as HOAs, to connect to OMWD’s recycled water distribution system.

OMWD produces up to two million gallons of recycled water every day at its 4S Ranch Water Reclamation Facility, which began operation in 2003. 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 expand the reach of the recycled water.
As a result, 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.
Water recycling is the process of capturing and treating wastewater for non-domestic purposes such as irrigation and industrial processes. 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.
The California Green Business Network and the City of La Mesa presented the Helix Water District with its Green Business certification at the June board of directors meeting. Achieving this certification recognizes the district’s ongoing commitment to environmentally responsible business practices.
To achieve certification, businesses and government entities must meet an extensive set of core and elective measures covering seven categories: energy, pollution prevention, solid waste, transportation, wastewater, water, and community.
“Our district’s focus on sustainability also has financial benefits,” said Dan McMillan, Helix Water District board president. “We can make decisions that are good for the environment as well as the ratepayer’s wallet.”

Helix has made significant investments in clean energy, securing a renewable energy supply through its power purchase agreement and further reducing its reliance on fossil fuels by installing solar panels at its Nat L. Eggert Operations Center. The agreement has delivered double-digit cost savings, reaching as high as 18% on electric commodity costs, over the last several years.
Helix has secured the renewable energy supply it needs through 2030.
The district currently fuels its fleet with 100% renewable diesel, which has reduced the district’s carbon emissions by an estimated 500 metric tons per year. It is also developing state-of-the-art charging infrastructure at its operations center to support its transition to an electric fleet.
This charging infrastructure is funded almost entirely through grants due to the district’s swift action in developing the project and securing funding.
Helix also underwent a lighting retrofit and installed energy-efficient window coverings at its facilities. It also installed lighting controls, features a programmable smart thermostat, and ENERGY STAR appliances to reduce its electricity usage. Through retrofits and the implementation of energy-efficient appliances and measures, the district has reduced its electricity consumption by 15%.
Additionally, a key priority of the district is educating customers on the responsible use of water, promoting the adoption of high-efficiency appliances and irrigation, and encouraging the use of climate-appropriate landscaping. Helix models water efficiency at its facilities through the use of low-water-use toilets, faucets, appliances, and irrigation systems.
These efficiencies allow the district to reduce its water consumption and long-term water costs.
“This certification proves that a government agency can prioritize sustainability while managing public funds responsibly,” said Helix Water District Board Director Mark Gracyk. “The district is proud to be an industry leader in sustainable and fiscally responsible business practices.”
