Pump Station, Headworks, and Blower Building

The Headworks and Blower Building Project consists of construction of a new headworks and secondary aeration blower system for the MSANK wastewater treatment plant. The MSANK wastewater treatment plant services a combined sewer collection system and is fed through an existing 15.5 MGD raw water pumping station. The secondary treatment portion of the plant treats 6.0 MGD of flow with 9.5 MGD of flow receiving primary treatment and disinfection prior to blending with the final effluent from the plant. Concern for safety of plant personnel due to degrading conditions in the existing pumping station necessitated replacement of the current pumping station. Conceptual planning expanded the project to address anticipated Long Term Control Plan (LTCP) requirements for the portion of the plant ahead of the primary settling basin and replacement and relocation of the secondary aeration blowers. This project includes construction of new 30.0 MGD raw water pump station; a new primary screening system; new grit removal facility; new odor control facility; new dual source electrical service; new plant-wide SCADA system; and new plant-wide non-potable and potable water systems.

Valley Camp Pump Station

The Valley Camp Pump Station Pump Replacement Project involved the replacement of the vertically driven shaft pumps and drives with two new dry-pit submersible pumps and variable frequency drives. Each newly installed pump is rated at ten horse power with a flow capacity of approximately 400 gallons per minute (sufficient enough to handle both dry weather and wet weather flows to the station). The station was also integrated into the supervisory control and data acquisition (SCADA) system to enable the authority to more effectively monitor the station remotely from the treatment.
