Description
The Idaho Department of Environmental Quality (DEQ) administers federal and state grants and low-interest loans to improve Idaho’s water resources. Drinking water assistance supports eligible public drinking water systems with facility planning and infrastructure needs that help ensure safe and adequate supplies. Wastewater assistance helps entities build or repair treatment facilities, achieve and maintain state and federal standards, or provide direct water quality benefits.
Funding opportunities include drinking water and wastewater planning grants, Drinking Water and Clean Water State Revolving Fund (SRF) loans, lead service line assistance, emerging-contaminant funding, and sewer overflow and stormwater planning grants. Supported work includes treatment improvements, source development, consolidation, inventories, and pollution-reduction planning. Emerging-contaminant programs prioritize PFAS, while sewer overflow and stormwater planning funding targets small or disadvantaged communities.
