The water and sewer mains are underground and unless you spot a hydrant have a tendency to be forgotten.  There are water service lines and sewer laterals running from the mains – through each yard – to every home.  These lines may be closer to the surface than you think.

Call 811 (Pa One Call) prior to digging.

The Borough has the responsibility to mark from the main to the curb box.
The responsibility to the home, falls on the homeowner.

Remember, there are a lot of other service providers who have their lines buried.
