Clean Water Indian Set-Aside Program

Grant Deadline
Environmental Protection Agency, Indian Health Service (IHS)

Submissions accepted on a rolling basis. The Clean Water Indian Set-Aside Grant Program (CWISA) provides funding to Indian tribes and Alaska Native Villages for wastewater infrastructure. The CWISA program is administered in cooperation with the Indian Health Service (IHS). The CWISA program provides funding for wastewater infrastructure to American Indian Tribes and Alaska Native Villages. Funds may be used for planning, design, and construction of wastewater collection and treatment systems. The CWISA program is administered by the Environmental Protection Agency (EPA) in cooperation with the Indian Health Service (IHS) Sanitation Facilities Construction program. To be considered for CWISA program funding, tribes must identify their wastewater needs to the IHS Sanitation Deficiency System. EPA uses the IHS Sanitation Deficiency System priority lists to identify and select projects for CWISA program funding.
