Water and Sewer Rates and Charges


Sewer Rates Appeal Form

Current Specific Water & Sewer Rate Charges:

The water rates in Phoenix have three main components: the monthly fixed service charge, volume (usage) charges and environmental charges.  Changes will be made to water and sewer rates in March of 2017.  There are a number of component parts to both the water and sewer rates, some of the rate components will not change and others will increase by varying proportions.  The changes are designed to result in an overall 2% increase in both water revenue and sewer revenue.  Individual customers may experience changes to their water and sewer bills that are either greater than or less than 2% depending on a variety of factors such as amount of usage, seasonality of usage, meter size, and customer type such as residential or industrial.

Current Rate Schedule effective March 1, 2017

Monthly Service Charge:

The fixed monthly service charge includes six (6) units of water (4,488 gallons) for October through May, and ten (10) units of water (7,480 gallons) for June through September. The service charge varies depending upon your meter size and whether you receive service inside or outside the city. Below is the service charge schedule for the current rates. All charges are subject to applicable sales taxes.

​Water Volume Charges:

Volume charges vary with the seasons and are assessed on water usage above the amount in the fixed monthly service charge. The amount a customer is charged for volume is based on metered consumption, and also varies depending upon whether you receive service inside or outside the city. The volume charge is highest in the summer months (June, July, August, and September); lowest in the winter months (December, January, February and March); and are priced in between during spring and fall months (April, May, October, and November). Below is the volume charge schedule for the rates effective March 1, 2017.

Learn How to Lower your Monthly Sewer Charge:

The best way to lower your monthly sewer charge is to use less water during January through March. To learn about ways to use less water, indoors and outdoors, request literature from the Phoenix Water Conservation Office.

If you own and maintain a swimming pool, another way to lower your sewer and your water charges when you refill the pool, is to do so when the water rates are at their lowest. And, if you refill the pool during the months of January, February or March, complete and submit a Request for Sewer Fee Adjustment form so the large volume charge doesn't impact your sewer charge. This form must be submitted by the end of September to be eligible for consideration.

Learn How to Reduce your Monthly Water Charges:

  • Limit your water usage to the amount in the monthly base fee to reduce your costs. The monthly residential water base fee of $5.10 includes 4,488
    gallons of water from October through May and 7,480 gallons from June through September. If you use this amount or less, you will not be charged
    additional water usage or consumption fees.

  • Use low water use plants and drip irrigation to reduce your water consumption. About 50% of water used in a typical residential home is for
    outdoor landscaping or swimming pools.

  • Reduce your consumption in January, February and March of each year and you could reduce your annual sewer costs. Your monthly sewer charge is
    calculated on your water usage in those months.​
