The Boucher Nissan car dealership that opened in Oconomowoc, Wisconsin, in 2023 decided to open another Hyundai dealership on the same lot in 2024. Unfortunately, the site was not equipped to handle the waste stream from another dealership.
Four 7,000-gallon holding tanks had to be installed over a two-year period. This translated into two tanks for each dealership. One 7,000-gallon tank was needed to hold sanitary waste, the other to contain the contents of the dealerships’ floor drains. As well, a 10,000-gallon holding tank had to be installed at the Nissan dealership’s car wash in 2023, plus a 2,500-gallon three-compartment tank
