Beaver Dam Wastewater Treatment Plant


HVAC, Pipe Fabrication & Plumbing Services for Wastewater Plants in the Beaver Dam Area

Upgrades to the Beaver Dam Wastewater Treatment Plant enable bioenergy generation that provides enough energy to power the plant and sells 800 kW of energy to the local utility provider. Ahern’s wastewater and alternative fuel expertise guided the installation of an anaerobic biological treatment system, methane recovery system, digesters, pretreatment systems, pumps, and associated piping. Biogas is generated through the treatment of high-strength cream cheese production waste from a nearby partner business. This project has been honored with an Environmental Protection Agency PISCES Award, and a Daily Reporter Top Project Award.
