ARPA POWTS Replacement Grant

With the release of funding from the American Rescue Plan Act (ARPA) in 2021, Calumet County has established a grant program for the replacement of Private Onsite Wastewater Treatment Systems (POWTS). The ARPA POWTS Replacement Grant is a competitive grant, which is intended to target older failing POWTS in Calumet County primarily located in the County's Groundwater Susceptibility Area. The Groundwater Susceptibility Area is a region of thin soils with porous bedrock located mainly within the Silurian Aquifer in Calumet County, which is highly susceptible to groundwater contamination.
