Water and sewer service area

Who Provides Water and Sewer Service in Rialto?

Rialto service can be confusing because not every property is served in exactly the same way. The City says it provides sewer services for most properties within city limits and water services for the central portion of the city. Rialto Water Services operates the systems under the City/Rialto Utility Authority arrangement, and West Valley Water District also serves some areas.

Rialto Water Services

Rialto Water Services provides water and wastewater services in the Inland Empire, with systems operated by Veolia North America.

City of Rialto utilities

The City utilities pages provide water/sewer service details, water rules, wastewater rates, utility rebates and provider information.

West Valley Water District

Some Rialto-area customers may be in West Valley Water District coverage. The City and RWS pages reference provider coverage maps, so verify your address if unsure.

📌
Address-check tip: Before starting service or questioning a bill, confirm whether your property is served by Rialto Water Services, City/Rialto Utility Authority service, West Valley Water District or a separate provider. Sewer and water provider may not always be the same for every Rialto address.

Rates, rebates and fees

Rialto Water/Sewer Rates, Wastewater Charges and Utility Rebates

The City of Rialto publishes water, sewer and wastewater rate resources and utility rebate information. If your bill is higher than expected, first separate usage charges, fixed charges, sewer/wastewater charges and any past balance before assuming the payment portal is wrong.

Water and sewer rates

Use the City’s Water & Sewer/Wastewater Rates page to review rate categories and current published rate information.

Utility rebates

The City says rebates may be available for residential and commercial customers, generally first come, first served and subject to requirements.

Water rules

Use the City utilities pages for Rialto/Rialto Utility Authority water rules, regulations and related utility information.

💵
Bill review tip: Look at each line item: water usage, meter/service charge, sewer or wastewater charge, past due balance, late fees and any special utility taxes or charges. This helps you ask a more focused question when calling customer service.
High bill and leak checks

What to Do If Your Rialto Water Bill Looks Too High

A high Rialto water bill can come from actual usage, irrigation, a running toilet, a hidden leak, extra household use, sewer/wastewater charges, rate changes, a previous balance or payment posting delay.

High-bill cluePossible causeFirst check
