Mill Creek Pump Station Improvements

Project Summary

This improvement project was designed by B.P. Barber & Associates, now AECOM, and constructed by M. B. Kahn for Columbia Water. The Mill Creek basin reaches into the Lower Richland and Old Hopkins areas. Mill Creek Pump Station is a Sanitary Sewer Lift Station that pumps wastewater flows to the Columbia Metro Wastewater Treatment Plant, another M. B. Kahn project site. M. B. Kahn completed a complete overhaul and upgrade that allowed Mill Creek to reach a capacity of 23 million gallons a day. M. B. Kahn constructed a new grinder vault along with several new bypass connections. Other tasks included the installation of a generator, several pumps, Variable Frequency Drives and Motor Control Centers along with final site improvements.
