CWSRF American and Steel and Build America, Buy America Requirements

American Iron and Steel Provision

The American Iron and Steel (AIS) provision requires Clean Water State Revolving Fund (CWSRF) and Drinking Water State Revolving Fund (DWSRF) assistance recipients to use iron and steel products that are produced in the United States. This requirement applies to projects for the construction, alteration, maintenance, or repair of a public water system or treatment works.

  • Learn more about AIS requirements and the waiver request process.

Build America, Buy America Act

The Build America, Buy America (BABA) Act establishes domestic sourcing requirements across all federal financial assistance programs for infrastructure. The aim of BABA is to build a resilient supply chain and manufacturing base for critical products in the United States that will spur investment in good-paying American manufacturing jobs and businesses. EPA’s efforts to implement BABA will help cultivate the domestic manufacturing base for a wide range of products commonly used across the water sector but not currently made domestically.
