The city owns 20 production wells located throughout the city. The Garden Lane Water Treatment Facility removes arsenic from the groundwater before distribution to the public water system. All water that is pumped is tested daily to ensure the highest quality water is delivered to Portage residents.
Water and Sewer service extensions in the City of Portage are partially funded by special assessments to the benefit properties. The City Charter includes a procedure to adopt a special assessment district consistent with State of Michigan laws.
