The City of Paynesville’s wastewater treatment facility needed improvements. Significant industrial users collaborated with the city and Bolton & Menk to develop the best fit wastewater treatment for the community. They chose to modify the existing aerated pond and spray irrigation system.
Bolton & Menk designed new grit removal, screening, and main lift station; expanded the aeration pond capacity; and renovated the irrigation pump station. Existing infrastructure, including 240 acres of stabilization ponds and 1,200 acres of spray irrigation fields, will continue to be used for final polishing and disposal. Because of the treatment and spray irrigation improvements associated with this project, the city secured a Beneficial Use of Wastewater Grant administrated by the MPCA. Bolton & Menk assisted in partnering the grant funding with a low interest loan administrated by the Public Facilities Authority.
