Water Quality Assurance

San Gabriel Valley Water Company  is committed to ensuring the health and safety of our customers through rigorous water quality testing, following standards set by federal, state, and local agencies.

​

The San Gabriel Valley faces water quality challenges due to industrial and commercial activities. However, by collaborating with partners at the local, state, and federal levels, we provide water that meets all drinking water quality standards.

​

Our state-certified water treatment operators collect water samples, which are analyzed by an independent, certified laboratory. Results are reported monthly to the State Water Resources Control Board, Division of Drinking Water.

​

Each year, a Consumer Confidence Report summarizes all water quality monitoring for San Gabriel. This report is available by July 1st for the previous calendar year in the Annual Water Quality Reports.

Water Testing Kit

  • Why Does My Water Look Cloudy?

    ​

    Occasionally, your drinking water may appear cloudy or milky due to air bubbles in the water. This is harmless. After a few seconds, the bubbles will rise to the top and the water will clear. There is no health risk, and your water is safe to drink.

  • Potable Water

    San Gabriel Valley Water Company provides reliable, high-quality safe drinking water from a mix of sources. Our supply includes locally-produced groundwater from 28 wells in the Main San Gabriel Groundwater Basin and 2 wells in the Central Groundwater Basin. We also have access to imported water through a connection with the Metropolitan Water District of Southern California and maintain emergency connections with nearby water agencies to ensure supply reliability.

    ​

    Recycled Water

    Water recycling is a vital, locally available resource that helps conserve high-quality drinking water. Recycled water, unaffected by drought and regional shortages, reduces the need for costly imported water and supports our long-term water efficiency goals.

    ​

    Recycled water is treated and disinfected municipal wastewater, suitable for non-drinking uses, such as irrigation for parks, golf courses, highways, school grounds, athletic fields, and industrial applications. Several agencies in the San Gabriel Valley and surrounding areas are expanding recycled water projects. Through separate pipelines from potable water, recycled water from Los Angeles County’s San Jose Creek and Whittier Narrows Reclamation Plants supplies large landscapes, conserving over 8 million gallons of potable water annually.

  • San Gabriel Valley Water Company uses "Best Available Treatment Technologies" to ensure drinking water is safe and free from harmful chemicals before delivery.

    ​

    Our team includes highly qualified, state-certified operators who maintain and operate a variety of treatment facilities. These facilities use advanced technologies to remove or reduce volatile and semi-volatile organic compounds, inorganics, and disinfection by-products. San Gabriel’s treatment facilities include:

    • Air Strippers and Liquid Phase Granular Activated Carbon for removing volatile organic compounds

    • Ion-Exchange Systems to remove perchlorate salts

    • Advanced Oxidation with UV Light to treat 1,4-Dioxane and N-Nitrosodimethylamine

    • Regenerable Ion Exchange System for nitrate removal

     

    We also use chlorination with sodium hypochlorite to disinfect and eliminate potential viruses and bacteria.

  • San Gabriel is required to provide a Public Health Goals (PHGs) report every three years for customers. This report includes information on any contaminants detected above the levels set by the State Office of Environmental Health Hazard Assessment (OEHHA) or Maximum Contaminant Level Goals (MCLGs) by the U.S. Environmental Protection Agency.

    ​

    PHGs and MCLGs are not water quality standards; they indicate extremely small risk levels. The PHG report explains potential risks associated with specific substances and provides cost estimates to reduce those contaminants to undetectable levels.

    ​

    2025 Public Health Goal Report

  • San Gabriel Valley Water Company has monitored lead and copper levels at customer taps across its distribution system since the late 1990s to comply with the Lead and Copper Rule (LCR). This federal regulation, enforced by the California State Water Resources Control Board, requires water providers to test for lead and copper every three years.

    ​

    Under the LCR, if lead exceeds 15 parts per billion or copper exceeds 1.3 parts per million in more than 10% of sampled taps, the provider must take corrective action. San Gabriel has never exceeded this 10% action level since the rule's implementation in 2014. For detailed results, please see our Annual Water Quality Reports.

Water Conservation

Water is vital to everyone and conserving it is essential. San Gabriel Valley Water Company is dedicated to safeguarding our water resources and supporting our customers in their conservation efforts. As part of California’s push for greater water efficiency, we have developed programs to ensure a reliable water supply for the future.


To reduce water loss, we maintain and upgrade our wells, pumps, reservoirs, and water mains, investing in new leak detection technology and training our field staff. We also offer educational programs and plumbing retrofits to help customers use water more efficiently.

  • Announcement on California's Drought Conditions

    On March 24, 2023, Governor Newsom issued Executive Order N-7-22, easing some drought emergency measures due to improved water conditions. However, Executive Order N-5-23 maintains certain restrictions to support communities still experiencing water challenges and to build long-term resilience.

    ​

    Current Drought Status While recent storms have provided relief, California remains in a drought emergency. Many regions, especially those relying on depleted groundwater, continue to face water supply shortages. The following restrictions remain in effect:

    ​

    Prohibited Water Uses

    • Outdoor watering that causes runoff onto sidewalks and hard surfaces (except incidental runoff)

    • Washing vehicles without a shutoff nozzle

    • Washing driveways or sidewalks that don’t absorb water

    • Street cleaning or construction site preparation with water

    • Filling decorative fountains, lakes, or ponds without a recirculating pump

    • Outdoor watering within 48 hours of at least 1/4 inch of rainfall

    • Watering decorative grass on public medians and non-functional turf in commercial, industrial, and HOA common areas

     

    Water Conservation Tips

    Outdoor Tips

    • Limit yard watering to three days per week, no more than 10 minutes per station, and water early.

    • Fix indoor and outdoor leaks within 5 days.

    • Adjust sprinklers to prevent overspray and runoff.

    • Replace lawns with California-friendly plants to save thousands of gallons monthly.

    • Use a broom or leaf blower instead of a hose to clean outdoor areas, saving up to 6 gallons per minute.

    Indoor Tips

    • Fix leaking faucets and running toilets to save up to 20 gallons daily.

    • Fill the bathtub halfway or less to save 17-25 gallons per bath.

    • Wash full loads of laundry to save 15-45 gallons per load.

    • Use a dishwasher instead of handwashing to save up to 24 gallons per load.

    • Install high-efficiency toilets to save up to 40 gallons per day.

  • California Water Use Restrictions

    California and much of the western U.S. have faced severe droughts over recent decades, leading to permanent water-use regulations to promote conservation. San Gabriel Valley Water Company customers have been among the most successful at saving water during these challenging times.

    ​

    Permanent Water Waste Restrictions

    To conserve water, customers should avoid the following:

    • Hosing down sidewalks, driveways, and other hard surfaces.

    • Washing vehicles with a hose unless it has a shut-off nozzle.

    • Running fountains or decorative water features without a recirculating system.

    • Watering landscapes in a way that causes runoff or within 48 hours of rainfall.

    • Using potable water for ornamental turf on public street medians.

Rates & Regulatory

Rate Setting Process

State law requires San Gabriel Valley Water Company (San Gabriel) to file a general rate case with the California Public Utilities Commission (CPUC) every three years. During this process, the CPUC conducts a comprehensive review of San Gabriel’s rates and operations, which includes:
⦁    Reviewing the company’s operations and expenses
⦁    Requesting additional information or clarification as needed
⦁    Conducting field inspections of existing and proposed facilities
⦁    Holding public hearings for customer feedback
⦁    Holding formal hearings with an administrative law judge


The CPUC then sets rates and terms of service for the next three-year period.


Between rate cases, San Gabriel may file special applications for issues that need to be addressed separately. Additionally, San Gabriel submits advice letters to the CPUC, which review past expenses to confirm they were necessary and prudent before being included in rates.


The CPUC also initiates its own proceedings on issues involving utilities. In these cases, San Gabriel submits expert testimony and comments as required.
