Drop Blue This calculator can be used to estimate your bill with the Proposed Rates for Fiscal Year 2020-2021. The proposed rates would become effective on or after July 1, 2010.

Water bills are calculated using IRWD’s budget based rate structure. The budget based rate structure provides you with the water you need and encourages the efficient use of water. How much you pay for each unit of water (a CCF is 100 cubic feet of water) depends on whether you stay within your water budget.
