From November 3 through November 13, we’re asking all Corona residents and businesses to temporarily reduce outdoor water use to help us manage a critical maintenance period. The Metropolitan Water District will undertake a non-routine inspection on a Feeder Pipeline at Lake Mathews, which delivers raw water to Corona’s surface water treatment plants.

While this work is outside the City’s control, we are taking proactive steps to adjust and continue providing reliable service. Corona’s water system is dynamic and resilient, drawing from multiple sources including local groundwater and imported supplies. However, to complete the work, Metropolitan will need to stop all water deliveries to the lower feeder pipeline, discontinuing the amount of surface water available to us.

How You Can Help:

• Turn off sprinklers and irrigation systems

• Only hand-water when necessary, and use a hose with an automatic shut-off nozzle

‍

Thank you for your understanding and partnership as we complete this important work. Together, we can ensure reliable service and keep Corona’s water system strong.

If you have any questions or concerns, please feel free to reach out to our Customer Care Team at CustomerCare@CoronaCA.gov.

We are open Monday through Thursday from 7:00 a.m. to 6:00 p.m.

FREQUENTLY ASKED QUESTIONS

What if there is a fire? 

The Operations team prepares a daily system model to ensure adequate fire protection and they will operate the system at the highest “risk” level for fire conditions. 

What is the City doing?

Most of the City’s parks and landscaping is irrigated using reclaimed water, but the City will be shutting off irrigation to all potable water sites for the 10 day period. 

Why does this have to happen now?

Metropolitan Water District is moving ahead scheduled inspection and repair of their equipment. This is out of Corona’s control and the Corona team has worked diligently to ensure contingencies are in place. 

My plants will die if I don’t water them.

We are asking you to turn off your automatic irrigation systems but you are welcome to hand water using a hose with a nozzle. Your plants should be okay with hand watering for a few days until you can turn your irrigation system back on.
