The wastewater treatment plant is located on the Yellow Breeches Stream, East of Boiling Springs, at 345 Lear Lane.
The plant began operation on July 20, 1977, was upgraded in 2016, and is of the Integrated Fixed-film Activated Sludge (IFAS) type with aerobic digestion of biosolids.
The original plant has a permitted capacity of .75 MGD (Million Gallons per Day), which was increased to 1.5 MGD in 2016.
65,000 square feet of reed beds were also constructed to improve biosolids processing. The reed bed system utilizes aquatic plants to dewater the biosolids and increases storage capacity.
As of December 31, 2020, the sewer system consisted of:
- 1.5 MGD treatment facility
- 11 Regional pumping stations
- 78 Miles of sewer mains

In addition to it’s own plant capacity, the South Middleton Township Municipal Authority owns 233,000 GPD capacity in the Mt. Holly Springs treatment plant, and 1.01 MGD in the Carlisle Borough treatment plant, in order to service South Middleton residents in those areas.
