MS4
A municipal separate storm sewer system (MS4) is a drainage system owned by a municipality, in this case the City of Greenville, that carries stormwater runoff away from buildings, roads, and other development to alleviate flooding. The drainage system is comprised of:
- Catch basins
- Curbs
- Ditches
- Gutters
- Man-made channels
- Municipal streets
- Roads with drainage systems
- Storm drains
This system is separate from the sanitary sewer system that carries sewage away from homes, schools, businesses, and other institutions.
