Each home or commercial building has a separate connection to the public sanitary sewer main called a sewer lateral. It is the property owner’s responsibility to maintain and repair their own sewer lateral from the house up to the point of connection with the public sanitary sewer main. This includes both the portion on private property and the portion located beneath the sidewalk and street up to the point where the lateral connects to the public main. The drawing below illustrates the difference between a sewer lateral and a public sanitary sewer main.

Troubleshooting

• Please be aware of where your sewer lateral is located
• Check to see if clean out is overflowing
• Check to see if tree roots are possibly causing blockage

Note: Human contact with sewage is a serious public health risk. Many waterborne diseases exist in household sewage. ! AVOID CONTACT!
