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 Review to request an adjustment to the measured water consumption used for calculation of your sewer charges. The 2022 sewer appeal process ends 60 days after the July 2022 billing period and is now closed for 2021. Please note, the 2022 sewer appeal will be for 2022 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 $4.64 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.
