Treatment Process Gallery

On a typical day, more than three million gallons of wastewater are transported to the wastewater treatment plant through nearly 138 miles of collection system pipes.  During heavy rain events or snow melt, the facilities can treat up to a rate of 28 million gallons per day (MGD).  Following are brief descriptions of the main treatment processes.  

When the wastewater reaches the plant, it is raised 30 feet by three, 15 million gallons per day (MGD) screw pumps.  Raising the wastewater allows it to travel by gravity through the rest of the treatment processes.  The influent pumping station is designed to accommodate a fourth pump in the future.
