The City of Mount Pleasant Wastewater Department operates an extended aeration treatment facility under a permit from the National Pollutant Discharge Elimination System (NPDES) for treatment and discharge of 710,000 gallons of effluent per day. The department has continually faced regulatory constraints from the Environmental Protection Agency (EPA) and the Tennessee Department of Environment & Conversation (TDEC). Recently, the department, engineers, and city leaders have created and implemented Capacity Management Operation Maintenance (CMOM) initiative requirements to direct their future projects to increase capacity and decrease non-compliance issues.
The department is responsible for the operation and maintenance of the wastewater collection system, including gravity sewer lines, force main lines, and sewage lift stations located throughout the service area. The department is currently working on inflow and infiltration projects to reduce the amount of ground and rainwater that enters the system. The city recently received $1.2-million in grant funds to replace parts of the collection system identified to be the main contributors of the inflow and infiltration problems.
