How We Manage Costs

Austin Water has made strategic infrastructure investments to ensure dependable water service while also improving affordability for customers using a multi-year debt management strategy that includes:

  • Securing near-zero percent interest loans to fund infrastructure improvements
  • Using tactics like debt defeasance and refunding to reduce debt costs
  • Ensuring that new developments pay their fair share for water and wastewater infrastructure through Capital Recovery Fees

These savings are then passed along to customers as:

  • Customer Assistance Program (CAP) for low-income residents
  • Temporary rate reductions to respond to events like the COVID-19 pandemic, or extreme freezing weather in February 2021
