In 1971, the City of Portage saw a need for a waste water treatment plant. Thus the first facility was built. That plant consisted of two primary clarifiers, two step feed aeration tanks and two final clarifiers.

In 1984, due to the City's growth, the plant was expanded. This expansion included a 3.5 million gallon Oxidation Ditch, four final clarifiers and the old step feed aeration tanks were converted into aerobic digesters. This expansion increased the capacity of the plant to 3.5 MGD.

Also in 1984 a Tertiary Filter system was installed to handle solids that might pass through the final clarifiers.

In 1984 a vacuum assisted drying bed was installed to dewater the biosolids that were produced in the facility.

Starting in 1997 and ending in 1998, the plant was expanded from 3.5 MGD to 4.95 MGD with peak flows up to 15 MG. The expansion included a new bar screen and grit system at the headworks, 2 new final clarifiers and a 1.5 MG excess flow basin. The basin is to be used to handle the peak flows that the plant receives during large rain storms. Before this expansion, the plant would bypass from time to time because of the big rain storms. Since the expansion, the facility has not had any bypassing.

In 2000, the old vacuum assisted drying beds were converted into a new maintenance shop.
