Lansing is a mid-sized city and the 6th-largest in Michigan, home to roughly 115,056 residents. Lansing's drinking water comes largely from the same regional sources that serve Michigan: Great Lakes and inland aquifers.
As elsewhere in Michigan, the central challenge is aging infrastructure. Surrounded by the Great Lakes, Michigan's defining issues are infrastructure trust after the Flint crisis and widespread PFAS sites.
Michigan reuses an estimated 3% of its treated wastewater and maintains minimal reuse programs; Lansing tracks no meaningful drought conditions on the U.S. Drought Monitor scale.
