Can anybody install a Private Onsite Wastewater Treatment System (POWTS)?
A POWTS can be installed by those individuals who have obtained the license classifications of Journeyman (JP or JPRS) and Master Plumber (MP or MPRS) designations awarded by the State of Wisconsin Department of Commerce. Only those who have obtained the classification of Master Plumber (MP or MPRS) can obtain a State sanitary permit. All Wisconsin licensed plumbers have certification cards that list their credential number. You can enter this credential number on the State of Wisconsin Department of Commerce licensing bureau website to find out whether the plumber is still in good standing.


If they do not have these credentials then they will not legally be able to install a POWTS in the State of Wisconsin. You can check the yellow pages for POWTS installers or contact Kenosha County Department of Planning and Development for a list of POWTS installers.
