Combined sewer systems are sewers that are designed to collect rainwater runoff, domestic sewage, and industrial wastewater in the same pipe. Most of the time, combined sewer systems transport all their wastewater to a sewage treatment plant, where it is treated and then discharged to a water body. During periods of heavy rainfall or snowmelt, however, the wastewater volume in a combined sewer system can exceed the capacity of the sewer systems or treatment plant. For this reason, combined sewer systems are designed to overflow occasionally and discharge excess wastewater directly to nearby streams, rivers, or other water bodies.

Morgantown Utility Board (MUB) operates a combined sewer system. As part of its program to educate the public about Combined Sewer Overflows (CSO’s), MUB offers this annual public notice. The intent of this notice is to create stronger public awareness of CSO’s and to promote greater public involvement in local CSO programs.

MUB has 40 combined sewer outlets. These outlets are allowed as part of MUB’s NPDES permit (number WV0023124). A complete list of CSOs, including their locations, can be found here.
