Private Sewage Systems

PRIVATE ON-LOT SEWER DISPOSAL SYSTEMS

PRIVATE ON-LOT SEWAGE DISPOSAL SYSTEMS


New construction outside of the PSDS (Public Sewer Disposal System) requires a perc test for a private on-lot sewer disposal system. This testing determines if the property is capable of the required processing.


Below is the Township Sewage Enforcement Officer, phone number, and application testing and permit pricing. Also listed is a notice from the DEP on “Understanding Septic Systems” for a clearer picture of what is necessary to proceed.


Any questions, please call the township office at 724-735-2705.
