Fond du Lac Wastewater Facility Advances RNG Pipeline Injection Project
The City of Fond du Lac’s Regional Wastewater Treatment and Resource Recovery Facility capped a strong year with a perfect compliance score from the Wisconsin DNR and a statewide operations award, while continuing construction on a new biosolids dryer and RNG pipeline injection project. Once complete later this year, the facility will convert all of its biogas into renewable natural gas while producing Class A fertilizer for local agriculture.
The upgrade is expected to create a new revenue stream for the city and reduce emissions, adding to a strong 2025 in which the plant treated 2.6 billion gallons of wastewater and beneficially reused 73% of its biosolids as fertilizer.
