Your Water Allocation. How is it Determined?

This calculator will help you understand how your monthly water allocation is determined.  It is useful both to IRWD customers and others who want to understand how this works. (Please note: Customers in the Orange Park Acres rate area are not on an allocation rate structure.)

For example:

IRWD Customers:  You can evaluate how different factors affect your existing allocation.

Non-customers:     You can estimate what an IRWD water allocation would be.

IRWD residential water allocations are based on the type of home, the number of people living in a home, the square footage of the irrigated landscape and other factors.

Instructions

1. Select your Account Type.
2. Enter the number of people living in your home.
3. Enter the approximate square footage of the irrigated landscaped area outside your home. This figure should not include the portion of your lot taken up by your house, nor should it include "hardscape" such as patio and sidewalk areas. If you have a pool, include it as if it were part of the landscaped area since the pool evaporates roughly the same amount of water used by plants.
4. Enter the month for which you would like an allocation.
5. Push the calculate button.
6. Click "Show Bill" to see more information.

Allocations vary from month to month. The calculator will return your target water allocation for the month indicated. The total is made up of an indoor water use allocation and an outdoor water use allocation. The total, shown in ccfs, is your target for water use that month. A ccf is one hundred cubic feet, or the standard unit shown on your water bill. One ccf equals 748 gallons of water.
