What is an illegal Connection?

An illegal connection is a connection that permits extraneous storm-related water (water from sources other than sanitary fixtures and floor drains) to enter the sanitary sewer system. The extraneous storm-related water is water that should be going to the storm sewer or allowed to soak into the ground without entering the sanitary sewer.

What are the Types of illegal Connections?
Illegal connections include connections of downspouts, sump pumps, and area drains to the house sewer lines. In addition, defective house sewer lines cause extraneous water to enter the sanitary sewers and thus they are also illegal connections.

What is a Sanitary Sewer?
