Q. CAC August meeting - How does stormwater get into the sanitary sewer system?

A. The role of the sanitary sewers is to transport wastewater from homes and businesses to the treatment plant. Along the way, some stormwater enters the sewer pipes. Some common sources of stormwater include – cracks in pipes or manholes, cross connections to the storm sewers or drains, and pick holes or vent holes in the manhole covers. The 2001 Task Force identified that 70 to 90% of the total sewer flow – in some portions of the system – was coming from footing drains during storm events.
