Side Sewers and Storms

Your home's side sewer runs from the house to the main sewer in the street. Blockages or flooding of the side sewer can cause sewer backups. Maintaining the side sewer is the owner's responsibility. In preparation for storm season, maintenance is more important than ever.

The Two I’s

Winter storms overload the sanitary sewer system in areas where there is excessive inflow and infiltration into the system (I&I). Inflow comes from stormwater connections to the sanitary sewer through roof gutters, sump pumps, yard or area drains. Iinfiltration comes from groundwater entering the sanitary sewer through cracks or otherwise defective pipes. The primarily source of I&I is from side sewers.
