The City owns and operates seven drinking-water-production wells that range in depths from 260 to 560 feet, each with a pumping capacity of approximately 1,000 gallons per minute. Three reservoirs store a total of 1,700,000 gallons of water. The Department of Public Works maintains approximately 80 miles of water-transmission and water-distribution pipelines. In 2016, 636,089,500 gallons of water were produced for 3,311 customers, some of whom were in Bear Creek and Resort Townships. Water-utility costs for 2017 have been budgeted at $2,520,400, with revenues estimated at $2,895,200.

From a network of approximately 50 miles of collection pipelines, which also includes 24 lift-pump stations, the Department of Public Works treated 404,982,000 gallons of wastewater in 2016 at a certified secondary-stage reclamation plant that has a design of 2,500,000 gallons per day. The Department treats wastewater for 3,079 customers within and near the City and is the treatment contractor for the neighboring Springvale-Bear Creek Sewage Disposal Authority that has 500 customers. Sewer-system costs, budgeted at $2,895,200 for 2017, would be offset by $2,942,500 in revenues. Treated wastewater from the City's reclamation plant is discharged into Lake Michigan, and treated stabilized biosolids are land applied on area farm fields as fertilizer.
