Getting Your New System Installed
1. Contact the Liberty Township office at 2857 Mercer Butler Pike, Grove City, PA

which you may need to comply.

marked.
3. “Call Before You Dig” Place a call to PA One Call, 1-800-242-1776. Let them
know you are doing a perc test. You will be assigned a PA One Call Ticket
Number which you must record for your records. PA requires 3 day’s notice prior
to excavation.
4. Contact the Sewage Enforcement Officer (SEO) assigned by Liberty Township.
Arrangements need to be made for the SEO, your excavator, and yourself to meet
at the property for the soil evaluation.
5. If the soils are satisfactory, your SEO will make arrangements with you to do the
perc test.
6. If the perc test passes, the results will be given to your contractor. If it fails to
pass, you will be notified by mail.
7. If your project is undergoing subdivision, required DEP planning modules will
need to be approved before your permit can be issued.
8. Once you receive notice that the perc test passes, your system must be designed
by a contractor that is licensed with this agency (see list below).
9. Submit design to your SEO for approval. Once approved, a permit will expire 3
years from the date of issue.
10. Your SEO must be notified to arrange for final inspection of your system. At this
point, your system will be installed but not yet covered.
