A sanitary sewer (also called, especially in the UK, a foul sewer) is a type of underground carriage system for transporting sewage from houses or industry to treatment or disposal. In some areas, sanitary sewers are separate sewer systems specifically for the carrying of domestic and industrial wastewater, and are operated separately and independently of storm drains, which carry the runoff of rain and other water which wash into city streets.

Sanitary lines generally consist of laterals (services to a particular unit), mains, and manholes (or other various forms of traps).
During the 1970's and 80's numerous trunk sewers were constructed, including major lines that parallel the Hinkson, Bear and Perche Creeks which serve as influent sewers to the Columbia Regional Wastewater Treatment Plant constructed from 1980 to 1982.
Sewer extension and trunk sewer construction has continued into the 2000's and the City's collection system, which extends beyond the city limits, consists of approximately 510 miles of sewer main lines and 10,100 manholes.
Two hydraulic sewer jet cleaners are used to clean sewer lines with high pressure water hoses removing grease, grit and other debris from the lines.
