Water, Wastewater, and Recycled Water Rates
Water, wastewater (sewer), and recycled water rates are calculated by the Utility Accounting Division and implemented by the Utility Services Division per City Ordinance Chapter 51.New rates went into effect as of July 1, 2015.Rates are based on meter size for water and based on meter size and Winter Quarter Average (WQA) of water use for the wastewater.

The Winter Quarter Average (WQA) is calculated by using your water/wastewater utility consumption used during the December, January, and February billing cycle.The WQA is used because it shows indoor domestic water consumption, which irrigation does not interfere with. If you are a new residential customer your WQA is based on actual consumption or the class average, whichever is less until the next WQA.Currently the residential class average is four (4) thousand gallons.

How the WQA is calculated:

  • The WQA is divided by the total amount of service days in the billing cycle to get a daily average usage.

  • The daily average is then multiplied by 30.42, or 30.50 for leap years, to get your monthly average.

  • (C ÷ D) × Y = WQA
    • C = Total Consumptions for the WQA billing cycle.
    • D = Total number of days in the WQA billing cycle.
    • Y = daily average multiplication number.
      • Use 30.42 for non-leap years.
      • Use 30.50 for leap years.
    • WQA = this is the gallons per month charged as your wastewater rate for the next year.

  • Once this is calculated the new wastewater rate based off of your WQA is started in March every year.

Current Water, Wastewater, and Recycled Water Rates:
  • Please see our Rate Sheet PDF for the current rates.
  • To help reduce your water/wastewater utility bill try:
    • Conserving water, fixing any leaking toilets or faucets, wash vehicles at a car wash, or replace your old toilets and washers with high-efficiency ones.Please see our Water Conservation page for more ideas.
