Description
The Idaho Department of Environmental Quality (DEQ) administers this fiscal year 2028 planning grant to address sanitary sewer overflows and municipal stormwater improvements. It supports inflow and infiltration (I/I) studies for wastewater collection systems or municipal stormwater planning studies, with funding intended for small or disadvantaged communities.
The program sits within DEQ’s broader work to improve Idaho’s water resources through federal and state grants and low-interest loans. Its rating form recognizes planning efforts that reduce infiltration and inflow or eliminate stormwater overflows, meet permit-driven planning deadlines, develop calibrated hydraulic models, or use collection-system inspections to identify structural deficiencies. Community affordability and disadvantaged status also contribute to project ratings.
