The Division of Industry Services Private Onsite Wastewater Treatment Systems (POWTS) Program protects public health and the waters of the state by regulating onsite wastewater treatment and recycling systems, and by promoting the use of the best available technology to provide onsite sewage treatment system solutions for property owners.

The Wisconsin Fund is a program that provides grants to homeowners and small commercial businesses to help offset a portion of the cost for the repair, rehabilitation, or replacement of existing failing Private Onsite Wastewater Treatment Systems (POWTS). Eligibility is based upon several criteria, including household income and age of the structure. 67 counties out of Wisconsin's 72 counties, the City of Franklin, and the Oneida Tribe of Wisconsin participate in the program. County government officials assist interested individuals in determining eligibility and in preparation of grant applications.

Questions regarding the Private Onsite Wastewater Treatment (POWTS) code can be sent to DSPSSBPowtsTech@Wi.gov.
