Current Rates Calculators

IRWD customer bills are calculated using IRWD's Budget Based Rate Structure. This rate structure provides you with the water you need and promotes water conservation and efficient use of water. Below you will find two types of rate calculators to help you estimate your bill and so you can see how your bill will change if you go over your monthly water budget.

This rate calculator uses Proposed FY18-19 IRWD rates that will be effective July 1, 2018 and can be used to estimate your bill with proposed IRWD rates.
