Sarah Nayes lives in Eau Claire and publishes Septic Service Wisconsin. She built it because finding a septic company should not take pages of ads, especially in January when the ground is frozen and something is backing up. The septic companies listed are real Wisconsin businesses with Google reviews. Rankings come from reviews and cannot be bought, and featured cards on city pages are paid and clearly labelled. Sarah also runs ConnectCraft AI, which builds websites, missed-call text-back and review systems for service businesses.
Why this directory exists
I live in Eau Claire, and I built this directory after seeing how hard it is to find a septic company when you need one. Search for septic pumping in most of Wisconsin and you get pages of ads, national lead sites and companies two counties away. That is a poor experience on a normal day, and a worse one in January, with the ground frozen and a drain backing up.
Septic service is also a decision you make more than once. Wisconsin requires a septic inspection or pumping at least every three years, and your county keeps track of it, so the company you pick is likely the one you call again and again.
I wanted one place that lists the Wisconsin businesses that do this work, says plainly what each one offers, and sorts them by what their customers say rather than by who paid. That is what this site is. Rankings come from Google reviews. Featured cards are paid, and they are labelled as featured wherever they appear.
If you own a septic company and something on your listing is wrong, claim it for free and I will fix it.
How listings are vetted
Every listing starts from the Google Maps category for septic system service in Wisconsin. We keep businesses with at least one customer review and drop duplicates, closed businesses and records that have not been updated in a year. Concrete plants and product makers that sell tanks but do not pump, inspect or install systems are left out.
For each business we read its own website and record what it offers as a yes, a no, or not enough info. A blank is not a no: it means the business has not published that detail yet, and a quick call settles it.
Right now that is 294 septic companies in 16 Wisconsin cities, last refreshed 2026-11-15.
Owners can claim their listing for free. Every claim is checked by a person: a real local business, a matching email domain or a call to the number on the Google listing. Paid placements are marked as featured, premium or best-of wherever they appear.
