The Border Environment Infrastructure Fund (BEIF), for project implementation, and the Project Development Assistance Program (PDAP), for project development, are grant programs funded by the U.S. Congress through the U.S. Environmental Protection Agency (EPA) and administered by NADBank.

This program offers grant financing exclusively for the implementation of high-priority municipal drinking water and wastewater infrastructure projects located within 100 kilometers of the U.S.-Mexico border.

Applications are received throughout the year and are evaluated periodically for placement within the ranked project application list. As additional BEIF funding becomes available, new projects will be selected and incorporated into the development pipeline.
