Frequently Asked Questions on Fiscal Year 2019 Rates and Monthly Charges

Why do water rates increase?
As an enterprise fund, Tucson Water must generate enough revenue to cover its operating costs. Without an increase, Tucson Water would not be able to continue to deliver safe, reliable drinking water to more than 731,000 people. Even though we continue to conserve more water, expenses to maintain the water system continue to rise.

Who approves water rate increases?
The City of Tucson Mayor and Council approve water rates. In May 2018, the Mayor and Council approved rates for Fiscal Year 2019 and Fiscal Year 2020. This action followed a series of public town hall meetings on water rates, a public hearing and the recommendation of the Citizens’ Water Advisory Committee.
