Marshall Water Treatment Plant

Marshall Water Treatment Plant | Marshall, MN

West Plains Engineering provided mechanical and electrical design services for the major addition and remodeling of the existing water treatment plant in Marshall, Minnesota. With the rapid growth of both the industrial and residential sectors within the city, the municipal utilities were forced to increase the capacity and the quality of the domestic water supply. It was decided that energy efficient, electric powered equipment would be utilized for heating and cooling this facility. A water source heat pump system was selected. These heat pumps, however, would not be provided with ground source loops or a traditional fluid cooler and boiler arrangement. This facility would make use of the water from the plant clear well to provide the heat transfer media for the entire facility. By using the geothermal style heat pump on this system, it was not necessary to provide a backup boiler to provide additional heat to the system during cold periods of the year. A new, single electrical service was required for the existing facility and addition. This was required to be completed with minimal down time to the facility. The new electrical system also included a generator, automatic power factor correction and sure protection. The generator backs up the entire facility with an automatic transfer switch.
