Program details

How it works

Marathon County says there are “currently a few sources” of financial assistance for low-income property owners, including the county’s POWTS Loan Program. The county’s septic systems page describes the program as a financing source tied to private onsite wastewater treatment systems (POWTS) and holding tanks.

What the money covers

The source page does not give a dollar cap on the loan, interest rate, repayment term, or a list of exact eligible project costs. It does say the program is for septic systems and holding tanks, and that the county has used a loan program to provide financial assistance to low-income property owners.

How to apply

The official page points residents to the Marathon County Conservation, Planning & Zoning Department for POWTS matters. It does not provide a specific application link or deadline on the page we found.

Timing and deadlines

The county page indicates the program exists now, but it does not state whether it is currently accepting new applications, on a waitlist, or closed.
