INFLOW AND INFILTRATION
Inflow and infiltration happens when rain, melted snow or groundwater gets into the sanitary sewer system. This can happen when roof downspouts, sump pumps or foundation drains are directly connected to the sanitary sewer and when underground water seeps into cracks or holes present in the sanitary sewer pipes. Inflow and infiltration could cause basement flooding and system overflow.
Sanitary sewers are underground pipes that carry wastewater from inside your home and direct it to the wastewater treatment plant. Wastewater comes from sources such as toilets, sinks, showers, dishwashers, washing machines and other appliances.
A typical eight-inch sanitary sewer can handle domestic sewage from up to 225 homes; however, it takes only five sump pumps operating at full capacity to overload an eight-inch sanitary sewer.
If you have roof downspouts, sump pumps or foundation drains directly connected to the sanitary sewer please contact the Water/Wastewater Department:
