​​​​​​2016 Water Rate Recommendation

Phoenix Water is recommending a three percent increase for water rates and a two percent increase for sewer rates, which equals a combined 2.6 percent increase for 2016. The proposed plan also includes a recommended two percent rate increase for 2017. 

If approved, the rate increase will provide funding for resources needed to invest in rehabilitation and replacement of the pipes, treatment plants, pumps, reservoirs, and wells that ensure reliable delivery of the city's drinking water.

The proposed rates roughly translates into a monthly increase of $1.59 for the average water customer. With the new rates in place, the average single-family residential water customer will pay $30.00 per month, and the average single-family residential sewer customer will pay $24.68 per month. Both of these rates are still among the lowest in the nation. ​​

If you have a question or comment about the department's rate recommendations, please email: watersmart@phoenix.gov.

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 $4.36 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.

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.

Monthly Operations & Maintenance Distribution  of Sewer Charges

Your sewer bill includes a base monthly service charge of $1.00 and a sewer service charge based on a portion of the average water consumption for the period of January, February and March.  The sewer service charge recovers operation, maintenance and new facilities costs.  The table below shows, by major user type, the percentage of the monthly sewer service charges attributed to operation and maintenance of the system.  40.32% of the sewer environmental charge is used for operation and maintenance of the system.  The remainder pays for new environmental facilities costs.  The sewer information is based on rates last adjusted in July 2012. This information is provided per Phoenix City Code Sec. 28-37 (b).
