Water and Sewer Rates
Current Water Rates
Phoenix Water is working on numerous water related projects to ensure all customers will have access to safe, clean and reliable drinking water for generations to come. These improvements will help keep water moving to homes and businesses even during water shortages along the Colorado River.
The water rates in Phoenix have three main components: the monthly fixed service charge, volume (usage) charges and environmental charges.
Below is a link to the current rate schedule, effective March 1, 2025.

The fixed monthly service charge now includes five (5) units of water (3,740 gallons) each month during the period from October through May, and eight (8) units of water (5,984 gallons) during the period from June through September.

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 five (5) units (3,740 gallons) of water monthly from October through May and eight (8) units (5,984 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.

Preventing an Increased Sewer Fee Due to Water Leaks
Preventing a higher sewer fee due to a significant water leak is a good reason to request a sewer fee review. Significant leaks, indoor and outdoor, can cause a spike in water usage, and if that happens during the first three months of the year, your sewer fee will increase. Keeping an eye on your water usage on your monthly bill will show you when those increases are impacting you water fee, and consequently, your future sewer fee. Many people will fix their leaks, but did not know they can have their sewer fee adjusted. If you know you had a leak during the first three months of the year, then you can submit a Sewer Fee Review online or download the form.
For Swimming Pool Owners
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, please visit MyPHX311, select "Submit Documents - City Services Bill" and select "Sewer Fee Review" from the pull down menu and fill out the online form. Please note, any attachments must be in non-editable format such as PDF. Photographs or screen-captures of documents are not acceptable. If you cannot use the online system, download the form here and submit it by mail. The sewer appeal process for 2025 is now open. Please note that the 2025 sewer appeal is for the January, February and March 2025 billing cycle. Sewer adjustments cannot be made for prior years.
