City of Pipestone, Minnesota

The City of Pipestone needed to address the high levels of chlorides, salty water parameters, dissolved solids, and elevated levels of radionuclides found in the treated wastewater to meet new discharge permit levels. The most economical choice was water softening. Pipestone’s water treatment facility was vintage. Its building and adjacent water tower are on the state historical register, making updating difficult and cost prohibitive.

Bolton & Menk worked with the city to develop a comprehensive plan and upgrade the water supply and treatment system. We worked with the city to develop plans for construction and helped access funding through the Minnesota Public Facilities Authority (PFA) and a Point Source Implementation Grant (PSIG).

With a construction timeline of 24 months, the new water treatment facility was completed in summer 2019 on time and within budget. The new facility provides a long-term investment in the community.
