Tucson Water, Arizona, USA – Planned Advanced Water Purification Facility
Tucson Water is taking a bold step toward a more sustainable water future. In partnership with the U.S. Bureau of Reclamation, Tucson Water is moving forward with the construction of a state-of-the-art Advanced Water Purification facility.
Funded through an $US 86.7 million federal capital program agreement signed in January 2025, this new facility will treat and purify up to 2.5 million gallons (9.4 million litres) of recycled water per day. The Advanced Water Purification plant is a cornerstone of Tucson’s One Water 2100 Plan, which emphasises using every drop of water wisely and keeping water local.
In exchange for the funding, Tucson Water will conserve a total of 56,000 acre-feet (69,000 million litres) of water in Lake Mead in a ten-year period – equivalent to enough water to serve thousands of Tucson households. This innovative project not only supports long-term water reliability but also strengthens regional water security across Southern Arizona.
By investing in advanced purification technology today, we’re protecting Tucson’s water future for generations to come.
