Water Budget Questions

Select a question to see the answer.

> Do tiered rates apply to everyone in the City?

Yes - the Tiered Rate structure applies to all customers: residents, businesses, schools, and City facilities. No one is exempt.

> Why do we pay for water?

Although water is a natural resource, it must be collected (from lakes, wells, and other sources), cleaned, tested, and then transported to the residence or business location. All of these steps are done by the City of Corona Department of Water & Power to ensure that all our customers have clean and safe water.

> My bill is in "units." How many gallons are in a unit?

There are 748 gallons in each unit. A unit is 100 cubic feet, or 1 CCF.

> What can I do if my budget is wrong?

If you are concerned about the estimated information used to determine your water budget, you may complete and submit a Variance Form to provide us with the actual information for your home or business.

> What can I do to make sure I stay within my budget?

There are many ways to ensure that you stay within your budget. The most important thing that you can do is check for breaks or leaks. Check your indoor fixtures, such as toilets and faucets, and your irrigation system and sprinklers. 

Next, check your bill to make sure that the number of people in your household is accurate and that you agree with the irrigated area that has been calculated for your residence. If you need to make a change to your budget, you may complete and submit a Variance Form.

You may also want to take advantage of current rebates on water efficient devices, landscape discounts and free landscape check-ups that the City of Corona Department of Water and Power offers to help you save water. Call our Water Resources team at (951) 736-2234 for more information on water conservation.

 

> What if I go over my budget?

If you go over your budget, you will be billed at higher price tiers for the water used over your budget.
The amount you'll pay depends upon the current water rates.

Please check your household to see if you have any type of break or leak that needs to be corrected. It is also a good idea to check your irrigation system to see if there is a leak or broken sprinkler that is causing an increase in your water usage. The irrigation timer may also need to be adjusted to the current weather conditions.

You may contact the City of Corona Department of Water & Power at (951) 736-2234 for a free landscape check-up to help ensure that your irrigation system is working properly, and check the Conservation pages for other water saving tips, as well as information on current rebate programs that are being offered.

If you had a leak that you've fixed, please fill out a variance form to request a one-time budget adjustment.

> If I don't use all of my budgeted water, can I roll it over to the next month?

No. Your water budget has been calculated for each month so that you should have enough water to use it efficiently.

If you think your budget is incorrect, please call us at (951) 736-2321.

> What if I have more than 4 people in my household?

You may complete a Variance Form and submit the signed form to the DWP.

Changes to your account will be made to accurately reflect your household and the changes will become effective with your next billing.

> I think my Irrigated area is wrong. What can I do?

You will need to complete a Variance Form and submit the signed form along with a sketch of your property on an 8 ½" x 11" sheet of paper to the City of Corona Department of Water & Power.

After review, the changes to your account will become effective on your next billing.


> What if I have a corner lot?

When your landscape area estimate was created, corner lots received more square footage to account for the additional parkway that corner lots have.


> What if I have a swimming pool?

Swimming pools and spas are included in your landscaped area estimate as they have an evapotranspiration (ET) rate that is similar to your landscape.


> Where does the evapotranspiration weather data come from?

The City of Corona Department of Water & Power uses weather data information from the California Irrigation Management Information System (CIMIS) Station #44, located at U.C. Riverside.
