Sanitary Sewer Maintenance is part of the Streets and Sewers Division, which is responsible for ongoing maintenance and repairs to sanitary sewer and combined sewer infrastructure. Major projects are usually contracted to the private sector and are overseen by staff of the Engineering Division. Emergency cave-ins are handled by both City workers and outside companies, depending on the situation.

City employees conduct a sewer cleaning program to ensure the steady flow of sewage from its point of origin to sewage treatment plants. Routine maintenance reduces the chances of a mainline sanitary or combined sewer from becoming obstructed with debris. This prevents sewage backup into basements or sewage overflow onto streets or into nearby bodies of water.
