SRF Clean Water Program

Learn how your community can receive low-interest loans to help create clean water systems.


This program is designed to provide a low-cost financing method that communities can take advantage of to make sure they are meeting water-quality standards.

The program emphasizes:

  • Watershed management priorities
  • Stormwater management
  • Green infrastructure

One major goal of the program is to encourage communities to undertake projects with meaningful water quality and public health benefits and which address the needs of the communities and the watersheds.

Eligible Projects

Funding is available for the planning and construction of projects including:

  • CSO mitigation

  • New wastewater treatment facilities and upgrades of existing facilities

In addition, non-structural projects are eligible for SRF funding, such as:
