Septic System FAQ's


1.  How does the new septic code affect me if I am selling my home and I have a cesspool?

According to N.J.A.C. 7:9A Standards for Individual Subsurface Sewage Disposal Systems, cesspools must be replaced at the time of real property transfer.  The rule does not specify who is responsible for necessary upgrades (seller or buyer).  This should be negotiated during the property transfer process.

 

2.  My septic failed the home inspection.  What does the town require?

Although the new rules establish a protocol for inspecting septic systems during property transfer, they do not mandate its use or require an upgrade to a system as a result of the inspection.  The inspection provides buyers and sellers with information based on a comprehensive evaluation of the system which can assist in negotiations for a transaction.  Unsatisfactory results, unless they indicate that the system is malfunctioning, do not require that anything be done immediately.

 

3.   What does the health department define as a malfunctioning system?

A.  Ponding or breakout of sewage or effluent onto the surface of the ground.

B.  Seepage of sewage or effluent into portions of the buildings below the ground.

C.  Backup of sewage into the building served which is not caused by a physical blockage of internal plumbing.

D.  Any manner of leakage observed from or into the tanks, connecting pipes, distribution boxes, and other components that are not designed to emit sewage or effluent.

 

4.  My system is malfunctioning.  What do I need to do?

If a conforming system can be installed on the property, then a conforming system will be required.  Keep in mind, this now includes advanced wastewater pretreatment systems that allow for small disposal fields, lower mound heights and drip dispersal options.  If a conforming system cannot be installed on the property, the health department has discretion in allowing a non-conforming system to be installed, provided the system is reasonably protective of public health and the environment and is currently allowed.  The last preferred option the property owner will have is to apply for a Treatment Works Approval for a holding tank.

 

5.  If there is no record of my septic diagram, how would I find the location of my system?
