Water and Sewer Rates and Charges




The Phoenix City Council has approved a 6% water rate increase for 2020. There is no sewer rate increase for 2020. With shortages looming on the Colorado River, Phoenix Water must build the infrastructure needed to pump and move alternative water supplies to portions of our distribution system normally served with Colorado River water. The rate increase will also 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 2020 rate increase goes into effect on February 1, 2020.


How Will the Rate Increase Affect the Water Portion of My City Services Bill?

These rate increases roughly translate into a monthly increase of $2.37 in 2020 for the average residential water customer. 

Phoenix water rates contain a generous "allowance" of water that is included each month in the fixed charge. For those that keep their water consumption within this allowance, average monthly bills will increase by only an additional 83¢ per month in 2020. Phoenix water bills rank as among the most affordable in the country.*

Current Water & Sewer 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 rates in February 2020.  There are a number of component parts to the water rates. Some of the rate components will not change and others will increase or decrease by varying proportions.  The changes are designed to result in an overall 6% increase in 2020.  Individual customers may experience changes to their water and sewer bills that are either greater than or less than 6% depending on a variety of factors such as amount of usage, seasonality of usage, meter size, and customer type such as residential or industrial.

​Water Volume Charges

Volume charges vary with the seasons and are assessed on water usage above the allowance amount included 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 February 1, 2020.

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. If you do refill the pool during the months of January, February or March billing cycles, complete and submit a Request for Sewer Fee Adjustment form to request an adjustment to the measure​d water consumption used for calculation of your sewer charges.   The 2019 sewer appeal process ends 60 days after the July billing period and is now closed for 2019. Please note, the 2019 sewer appeal is for 2019 January, February and March billing cycles only.  Sewer adjustments will not be made for prior years.​ 


Learn How to Reduce your Monthly Water Charges

  • Limit your water usage to the allowance amount in the monthly base fee to reduce your costs. The monthly residential water base fee of $4.25 for customers with a 5/8" meter includes 4,488 gallons of water monthly from October through May and 7,480 gallons from June through September. If you use this amount or less, volume charges will not apply; however, environmental charges are assessed to all consumption. 

  • 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.​
