The Clean Water Infrastructure Act of 2017 invests $2.5 billion in clean and drinking water infrastructure projects and water quality protection across New York. It provides at least $1 billion for the New York State Water Infrastructure Improvement Act of 2017 (WIIA), which authorizes the New York State Environmental Facilities Corporation (EFC) to provide grants to assist municipalities in funding water quality infrastructure. WIIA grants are available for both drinking water and sewage treatment works (clean water) projects. 

A clean water project may be eligible for a WIIA grant of up to the lesser of 25% of total eligible project cost after deducting other grant funds awarded for the project or:

  1. A project less than $50 million: $5 million;
  2. A project equal to or greater than $50 million, but less than $100 million: $12.5 million; or
  3. A project equal to or greater than $100 million: $25 million.

A drinking water project may be eligible for a WIIA grant of up to the lesser of $3 million or 60% of the total net project costs.

For more information on the WIIA program, please refer to the WIIA Grant Summary.


Municipalities, including any county, city, town, village, district corporation, county or town improvement district, school district, Indian nation or tribe recognized by the state or the United States with a reservation wholly or partly within the boundaries of New York State, any public benefit corporation or public authority established pursuant to the laws of New York or any agency of the State that is empowered to construct and operate a water quality infrastructure project. School districts are eligible for a WIIA or IMG grant, but are ineligible for CWSRF financial assistance.

Water quality infrastructure projects funded through the WIIA grant program will be awarded to sewage treatment works projects for the replacement or repair of infrastructure, or compliance with environmental and public health laws and regulations related to water quality. 

In addition, for Drinking Water, those types of infrastructure projects defined as eligible by the DWSRF program may compete for WIIA grant funds. Projects eligible for WIIA grant funding include investments to upgrade or replace drinking water infrastructure, address noncompliance with federal or state drinking water health standards, prevent future violations of such standards, and provide the public with safe drinking water. 

In order to be eligible, applicants must meet the following criteria:

  • Include construction services.
  • Have not closed on an SRF financing or short-term financing was closed on or after October 1, 2016. However, applicants that have submitted an acceptable application in previous rounds of the WIIA grant program are grandfathered.
  • Construction cannot have been completed before October 1, 2017.

Funds made available through the WIIA grant program can be used for costs associated with project planning, design, and construction services as long as those costs result in a completed eligible sewage treatment work infrastructure improvement project.

Evaluation Criteria

In evaluating projects, EFC and DOH will consider factors such as the water quality improvement or reduction in risk to public health, financial needs of the community, readiness to advance construction, and the level of demonstrated community support.
