Grants and Loans

We administer federal and state funds for grants and low-interest loans to improve the quality of Idaho’s water resources. Our drinking water grants and loans assist eligible public drinking water systems with facility planning projects to ensure safe and adequate drinking water supplies. Our wastewater grants and loans help entities build or repair existing wastewater treatment facilities to achieve and maintain compliance with state and federal standards or to provide direct water quality benefits.
