What causes a sewer back up?

Clogs or blockages in sewer lines can be caused by materials settling in the pipe and, in turn, partially or completely block the sewer pipe. Such blockages can occur either in the Authority's main sewer line or in the private sewer service line that the property owner owns and maintains.

The private line, also known as the lateral line, connects your home or building to the public sewer system. Wastewater from your sinks, showers, toilets, dishwashers and washing machines flow through the lateral line to the public sewer system. Lateral lines can be blocked or obstructed by items flushed down the toilet or washed down the dtrain, as well as by tree roots and other obstructions.

​Ways to avoid backups are: Never pour grease or oil down a drain, including a garbage disposal; never flush any non-soluble down the toilet; never connect roof drains, downspouts or sump pumps to the sewer drain pipes.
