What is private property Infiltration and Inflow?

Water can enter the sewage system in many ways, including leaky pipes and connections, often on a homeowner’s own property. The increased flow after a storm can cause problems throughout the system, including your basement.

But basement backups are only a symptom. The problem is bigger and requires a bigger solution – full cooperation from all municipalities, neighborhoods and homeowners. It’s a serious problem, and it will not go away. In fact, it will only get worse if we don’t get to work.
