City of Pipestone, Minnesota


The City of Pipestone was plagued with significant inflow and infiltration (I&I) in their sanitary sewer system. This I&I caused hydraulic overloading of wastewater treatment ponds and lift stations. When the system was overloaded, the city was forced to bypass excess untreated wastewater into nearby public ditches and waterways.

Bolton & Menk worked with the city, MnDOT, and Minnesota PFA to identify issues and scope as well as coordinate funding for a five-block segment of TH 30 suspected to be a significant source of the city’s I&I problems. This project demonstrates how high-level cooperation between government entities can create resourceful, cost-saving solutions.

Bolton & Menk worked with the city and other entities to find a real solution that was smart, effective, and affordable. Early and ongoing communication with stakeholders helped maintain a tight but optimal project schedule. This project reduced I&I, alleviated flooding of the bridge underpass, and improved the road surface for the betterment of the citizens of Pipestone and the many travelers who pass through town each day.
