The South Dakota Department of Ag and Natural Resources is allocating $175 million in federal grants.

The American Rescue Plan Act money is going toward grants for drinking water, wastewater system improvements and the state’s riparian buffer initiative. The department is awarding $105 million in grants to nearly thirty water districts and rural water systems to improve drinking water across the state.

Another $65 million is going toward almost 20 cities and sanitary districts for waste and stormwater projects.

The department is investing $5,000,000 into riparian buffer grants. A riparian zone is a conservation practice that encourages vegetation growth along the edges of rivers, stream and lakes to help improve water quality.
