Interest-free or low-interest financing for wastewater and sewer infrastructure projects.
Clean Water State Revolving Fund
The Clean Water State Revolving Fund provides interest-free or low-interest rate financing for wastewater and sewer infrastructure projects to municipalities throughout New York State. A variety of projects are eligible for financing, including construction or restoration of sewers and wastewater treatment facilities, stormwater management, landfill closures, as well as habitat restoration and protection projects. 

There are several different types of financing available to clean water project applicants. EFC provides both short and long-term financing, interest-free or low interest to accommodate municipalities of all population sizes with varying financial needs. 

When communities repay their financings, it allows EFC to finance new projects and the funds "revolve" over time.

List Your Project in the Intended Use Plan
The first step in seeking State Revolving Funds
An Intended Use Plan (IUP) is prepared annually to account for how the Clean Water State Revolving Fund (CWSRF) will be used during a federal fiscal year.

Any project funded by the State Revolving Fund is required by law to be listed in the IUP. Projects are listed using the Project Listing and Update System (PLUS). The requested information includes contact information, a general description of the project’s scope, a budget, and a project schedule. Projects are then screened for eligibility, scored, ranked, and listed.

You must submit an approvable engineering report and Smart Growth Assessment Form with the project listing or have one on file in order to be on the Annual List. You can submit a complete formal financing application if your project is on the Annual List of the IUP.
