Theis Septic Service in Winona, MN
About Theis Septic Service
From the website of Theis Septic Service, read 15 Sept 2026. It describes what the company says it offers, not independent verification.
Theis Septic Service pumps septic tanks and replaces outlet baffles, the parts that let clear water leave a tank on its way to the drainfield. Pumping can mean digging up a small section of the yard, and the company says it takes pride in how the site is left once the work is done. From the baffle, that clear water spreads into the drainfield, where the ground absorbs it.

Outlet Baffle
The clear water exits the tank through an outlet baffle and is dispersed into the drainfield which absorbs the water.

Local Ground
Around Winona, the main drain-field limit is slow water movement: water leaves the soil too slowly for a conventional field to keep up. Site conditions on any one lot can differ from the map. See the Winona city page for the full soil profile.

Before You Call
Deciding when the tank is next due for pumping is the call most homeowners face, and it is the service repeat customers say they book again and again. A question worth asking on the phone: whether the outlet baffle should be looked over while the tank is open, since Theis handles baffle replacement as well.
