Water Quality & Regulatory
Water Quality Assurance
Fontana 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.
Fontana Water Company 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 Fontana. This report is available by July 1st for the previous calendar year in the Annual Water Quality Reports.
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
Fontana Water Company’s water supply is produced from Lytle Creek surface flow, and from wells in the Lytle Basin, Rialto Basin, Chino Basin, and another groundwater basin known as No Man’s Land. Water from the California State Water Project is purchased from the Inland Empire Utilities Agency and San Bernardino Valley Municipal Water District. A portion of the water supply can be purchased from Cucamonga Valley Water District during water shortages or under emergency situations.
Lytle Creek surface flow begins at the Intake, located in the Lytle Creek Canyon north of Fontana Water Company’s service area. Water from Lytle Creek is diverted into the “upper penstock” pipeline where it flows by gravity to the Afterbay.
The Afterbay, is a diversion facility located immediately downstream from Southern California Edison Company’s hydroelectric power plant. Once surface water enters the Afterbay, it is delivered by pipeline to Fontana Water Company’s Sandhill Surface Water Treatment Plant, where it is blended with water from the California State Water Project for treatment and disinfection before entering the distribution system.
Additionally, Fontana Water Company produces groundwater from 29 wells in and around the City of Fontana and more specifically located in the Lytle Basin, Rialto Basin, Chino Basin and No Man’s Land.
Fontana Water Company’s goal is to provide the highest quality of water for its customers. In order to meet this goal, Fontana Water Company owns and operates three water treatment facilities, treating a combination of well and surface water.
Plant F10 – 5,000 GPM Liquid Phase Granular Carbon facility for the removal of Volatile Organic Compounds.
Plant F17 – 6000 gallon per minute Ion-Exchange facility for the removal of perchlorate.
Plant F21 – 2500 gallon per minute Ion-Exchange facility for the removal of perchlorate.
Plant F23 – 2500 gallon per minute Ion-Exchange facility for the removal of perchlorate
Sandhill Water Treatment Plant – A 29 million-gallon-per-day (MGD) treatment plant that is comprised of a 12 MGD Conventional filtration treatment facility and 17 MGD Diatomaceous Earth filtration treatment facility. The source water for this treatment plant is local Lytle Creek surface water and State Water Project supplies from Northern California.
Fontana Water Company plans to install additional treatment systems similar to the system at Plant F17 in order to utilize wells currently not in use.
The Public Health Goals (PHGs) report is a legislative requirement to provide you with information on the detection of any contaminants above levels stated in PHGs adopted by the State Office of Environmental Health Hazard Assessment (OEHHA) and any contaminants above the Maximum Contaminant Level Goals (MCLGs) set by the United States Environmental Protection Agency. Public water systems serving more than 10,000 service connections are required to prepare a written report available upon request every three years. PHGs and MCLGs are not water quality standards. They are goals identifying extremely small risks. Additionally, the PHG report intends to provide an estimate of the cost to reduce the contaminant from drinking water to non-detectable levels regardless of how minimal the risk might be.

Fontana Water Company Statement of Completion
Fontana 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. Fontana has never exceeded this 10% action level since the rule's implementation in 2014. For detailed results, please see our Annual Water Quality Reports.

Rates & Regulatory
Rate Setting Process
State law requires Fontana Water Company 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 Fontana’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, Fontana may file special applications for issues that need to be addressed separately. Additionally, Fontana 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, Fontana submits expert testimony and comments as required.
Learn more about the CPUC's rate-setting process by watching this video about How Rates Are Set.

Conservation
Water Conservation
Water is vital to everyone and conserving it is essential. Fontana 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

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.
Violations may result in daily fines, issued by local agencies or in cooperation with San Gabriel Valley Water Company.
