The Michigan Department of Environmental Quality is awarding $158 million in low-interest loans to 15 projects for improvements to water system infrastructure around the state.

The loans are part of the state’s 30-year Water Strategy for the protection and use of the state’s water resources.

“It’s essential to keep our waters clean from sources in groundwater, lakes and rivers to end-of-pipe delivery points to sustain the ecosystem and provide high-quality resources to our citizens,” said Jon Allan, director of the state’s Office of the Great Lakes.

The loans will go primarily toward improvement projects in southeast Michigan.
