sewer lines

Waste water conduits

Sewer lines are the underground pipes that carry wastewater and sewage away from buildings to treatment facilities or disposal sites.

These pipes form interconnected networks beneath streets and properties, ranging from small household connections to large municipal mains.

Problems with sewer lines—clogs, cracks, tree root intrusion—can cause backups and require expensive repairs.

The city is replacing the aging sewer lines on our block.
