Wastewater Department
The City of Mount Pleasant Wastewater Treatment Plant (WWTP) is responsible for treating all residential and commercial sanitary sewage generated in the City Limits. Sewage is transported through the collection system, which includes 15 lift stations. Pumps raise the liquid to a level from which it can flow by gravity to the plant. The WWTP is an advanced secondary plant that utilizes primary sedimentation, Bio-Towers, Rotating Biological Contactors, Final Clarification, chlorination and de-chlorination for treatment of wastewater.
The Wastewater Department staff are responsible for repairs and maintenance to the equipment at the Plant, as well as the Lift Stations. Plant staff also monitor and perform laboratory analysis on the sewage as it undergoes treatment at the Wastewater Plant. The treated sewage must meet stringent State and Federal Standards before it can be discharged to the Chippewa River. The wastewater treatment plant is a Michigan Department of Environmental Quality (MDEQ) approved septic receiving station, and accepts septage from septic tank waste haulers.
All plant operators are required to hold a minimum of a Class D Wastewater Treatment license as issued by the MDEQ. Combined, the Wastewater staff has exceeded State standards by obtaining Class A, Class B, and Class C Wastewater Treatment licenses. Operators attend many training courses throughout the year to stay updated on the industry and to increase job knowledge.
