Annual Drinking Water Report
The purpose of this report is to provide information about the quality of the water delivered to customers this past year of 2021. This report is mandated by the United States Environmental Protection Agency (USEPA) and we believe it is your right to know where your water comes from and what it contains. We are happy to report that we have consistently delivered water that has met or exceeded the standards set by State and Federal Law. More information about contaminants and potential health effects can be obtained by calling the USEPA's Safe Drinking Water Hotline 1(800) 426-4791. For information regarding this Consumer Confidence Report please contact David Terry, Project Manager -Veolia. (909) 820-0400.
About Rialto Water Services
The City of Rialto and Rialto Utility Authority (RUA), in partnership with Rialto Water Services (RWS) formed a public- private partnership to execute a 30 year water and wastewater concession. RWS is a partnership between Table Rock Capital and the Union Labor Life Insurance Company (Ullico). RWS contracts with Veolia North America to operate the water and wastewater systems.
Under the Concession Agreement, the City retains full ownership of the water and wastewater systems, retains all water rights and supply, and possesses the rate-setting authority associated with the facilities. RWS provides financial backing, oversight and concession services while Velia delivers all water and wastewater services, including billing and customer service, and oversees a $41 million capital improvement program to upgrade aging facilities.

CITY OF RIALTO WATER QUALITY RESULTS FOR 2021
The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently.

Waterand EmployeeQuality
Rialto Water Services is proud to inform residents that the Water Division has passed another annual water quality checkup. City of Rialto Water has met all the Clean Water Standards set forth by the State and Federal Governments in 2004. Part of meeting these requirements is having California Water Resources Control Board and American Water Works Association (AWWA) certified employees in water distribution, treatment and cross connection/ backflow protection. Certifications are obtained by taking college level courses in water science and engineering. We have entered into a collective bargaining agreement that has placed even higher standards on operators and certification levels. In addition, staff continues to upgrade certifications as a part of our continuing education program. State and federal certifications allow us to operate and maintain the public water system for the City of Rialto. This is just one of the many committed efforts we put towards producing clean drinking water for our customers.

• Fill washing machines and dishwashers before running
them. Partial loads use the same amount of water as full loads.
• Little leaks add up in a hurry. A dripping faucet or a toilet leak can add up to hundreds of gallons of wasted water.
• Turn off the water while you brush your teeth.
• Be sure to use low-flow showerheads and install aerators on your kitchen and bathroom faucets. They restrict the flow without compromising water pressure.
• Do not use a hose outside to clean sidewalks and
driveways; instead use a broom.
• Follow the Stage 2 Water Alert restrictions issued by the City. • Be waterwise and think before you turn on the tap.
