The call came late in fall 2019 from the Chippewa County Humane Association in northern Wisconsin. The onsite system at the animal shelter was failing, and they asked Joe Rubenzer at Stolt Excavating & Trucking in Chippewa Falls, if his company could install a new drainfield.
Rubenzer agreed to look at the situation, but first he pulled the county’s sanitary records. They said two drainfields had been installed on the property in the previous 15 years.
“I said, ‘You guys have something else going on here. I think we need to look into this deeper,’” Rubenzer recalls.
He contacted Mark Prevost at First
