On June 20, 2025, Aqua Texas filed an application to adjust water and wastewater rates to reflect nearly $700 million in capital infrastructure projects we made between 2004 and the end of 2024. Our request, Aqua Texas’ first statewide in 20 years, allows us to continue our infrastructure work that improves reliability and water quality, enhances customer service, and helps to support our commitment to the communities we serve.
This includes replacing hundreds of miles of aging water main and associated valves and customer service lines throughout the Lone Star State.
Examples of infrastructure investments we have made across the state include:
- Water main replacements
- Drilling new wells to provide additional water
- Building new water plants, including our only surface water plant in the state
- Building new wastewater treatment plants
- Installing new ground storage tanks, as well as rehabbing existing ones
Aqua Texas’ requested base rate increase requires review and approval by the Texas Public Utility Commission (PUC).
