Allocated vs. Estimated
Within your bill’s total monthly costs, you may see a Water System charge and Wastewater Services charge. Water System charges help pay for the cost associated with operating and maintaining the District’s water treatment and delivery system. This fee includes fixed meter charges that remain the same every month, which are determined by meter size, not by the amount of water delivered. Wastewater Services charges pay for the cost associated with operating and maintaining wastewater lines and the treatment of wastewater flows. Learn more

Persons Per Household
Indoor allocations are based upon the number of individuals in each household and East Valley Water District automatically allocates four individuals per home. If more individuals reside in your household, please submit a Variance Request and we can provide an expanded water allocation.
Daily Gallons Allocation
Indoor budget allocations are developed based on indoor water use standards adopted by the California Regional Water Quality Control Board. Currently, the Tier 1 budget includes 55 gallons per person per day of water usage consistent with State Guidelines.
