Fact Sheet about DWSRF Tribal Set-Aside Program

What is the DWIG TSA Grant Program?
The Drinking Water Infrastructure Grants Tribal Set-Aside (DWIG TSA) Program provides grant funds to improve the infrastructure of drinking water systems that serve Indian Tribes. It is a component of the Drinking Water State Revolving Fund. [see the Safe Drinking Water Act (SDWA) 1452(i) and 1452(a)(2)]

Who is eligible to receive grant from the program?
Any federally recognized Indian Tribe is eligible to receive a grant. The State of Alaska is also eligible to receive funds for projects for Alaska Tribes. Tribes may also request that project funds be directed to the Indian Health Service, if the Tribe would like the IHS to administer the project and IHS agrees to do so.

What type of projects are eligible for funding?
Most projects that improve a Tribal community, or non-profit non-community, drinking water system are eligible to be funded with DWIG TSA grants. Some examples are projects to: rehabilitate or develop sources of drinking water; install or upgrade treatment facilities; install or upgrade storage facilities; install or replace transmission or distribution pipes; and replace aging water system infrastructure. Funds can also be used to conduct project feasibility studies, engineering design work, and project administration.

How is the Grant Program administered?
All available DWIG TSA funds are allotted, by formula, among EPA's Regional offices. The Regional offices then identify, rank, select, and make awards for the projects based on the available funding.

How are funds allotted among the EPA Regional offices?
The funds are allotted, by formula, among nine of the ten EPA Regional offices (Region 3 does not have any federally recognized Tribes within its area of coverage). The formula provides, to each Regional office, a "base" amount that is 2% of the total annual DWIG TSA set-aside. The remaining funds are allotted to the Regions based on their percentage share of the Tribal drinking water system "needs" that are identified in two different "needs" surveys. The first is EPA's "Drinking Water Infrastructure Needs Survey" (DWINS) which is conducted every four years - the second is the Indian Health Service's (IHS) "Sanitation Deficiency System" which IHS updates annually.

What is the difference between Tentative and Final allotments?
EPA calculates the allotments twice for each fiscal year. Tentatie allotments are based on the amount of funding that is requested in the federal budget for the upcoming federal fiscal year. The budget is normally released in February of each year and the Tentative allotments are calculated a month or two later. Once EPA receives an appropriation from Congress for the new fiscal year, we recalculate the allotments based on the funds that are actually available. These are the final allotments. This step normally occurs within a few months after the start of the new federal fiscal year. When the amount of funds appropriated is the same as the budget, the Tentative and Final allotments are identical.
