The purpose of this effort is to outline and describe the current status of Marathon County’s POWTS Maintenance Program and future requirements for the program.  POWTS is an acronym for Private On-site Wastewater Treatment Systems, commonly referred to as “septic systems”.  POWTS refers to all types of private sewage systems, including conventional, at-grade, mound, holding tank and other types of systems.  Information is being provided to facilitate discussion and to increase understanding of the requirements in order to develop administrative guidelines for an expanded maintenance program as mandated by Wisconsin Statutes and Administrative Code by no later than October 1st, 2019.
