Project Summary

Klingner provided full professional services for the City of Lewistown for upgrades to their Wastewater Treatment Facility (WWTF). Klingner performed a preliminary engineering report to add disinfection to the lagoon discharge and make improvements in the treatment to remove ammonia to meet DNR guidelines. The project consisted of the conversion of a 75,000 GPD aerated 3-cell lagoon to a storage basin with a center pivot land application for a “no-discharge” system. In the new design, two center pivot irrigators cover 44.2 acres of row crops. Klingner prepared easements for the associated sewer force main. Klingner also designed and constructed a fourth lagoon cell and a duplex 500 GPM pump station with UV disinfection integrated into the pump house.

The WWTF project included lease negotiations with landowners. Funding was secured through a USDA Rural Development Loan and Grant, as well as CDBG Grant Funding.
