The City of Corona Utilities Department provides clean, high quality water delivered straight to your tap at very reasonable rates.
The Utilities Department has a tiered rate and water budget program, which is effective at promoting efficient water use and resource conservation. There are two billing components to water service: commodity charges for water used and a fixed Readiness to Serve charge.
