What the grant program offers

The DWGTF Source Water Protection (SWP) Grant Program offers funding to permanently conserve our water supply lands through land acquisition and conservation easements. Grants cover up to 50% of eligible project costs with a maximum grant award of $500,000. Eligible project costs are pro-rated to the percent of eligible source water lands that overlap the project property.

Eligible Applicants

  • A State agency, board, or commission or any political subdivision of the State;
  • Any person or legal entity, such as a sole proprietorship, partnership, corporation, association, or non-profit organization, that owns a community water system or water distribution system;
  • A non-profit organization that owns a non-transient, non-community water system;
  • A land trust or other non-profit organization that has among its purposes the conservation of land; or,
  • Other entities approved by the Commission consistent with RSA 485-F.

Finding Eligible Source Water Land

Wellhead Protection Areas (WHPAs) for active wells used by a community or non-transient, non-community public water system, and Hydrologic Areas of Concern (HACs) are automatically eligible source water lands. Future Water Supply lands need to be approved by the Advisory Commission’s Application Review Subcommittee at the Eligibility Application stage.

A map of eligible land can be accessed through the NHDES OneStop Data Mapper. It is important to read through the Identifying Eligible Land GIS Guide on how to access the database before entering the Data Mapper. You will need a PIN and password provided by NHDES to access the database. When requesting a PIN, explicitly state the nature of your organization (whether a municipality, water supplier, or a conservation organization) and that you are applying for the DWGTF Source Water Protection Grant Program.
