Perc Test

A two-part test to assess absorption rate of your property.  The results, when interpreted by the Sewage Officer, will help determine the size and type of septic system you need to build.

Dye Test

A tracing test performed by our Sewage Officer to ensure that wastewater and "gray" water are correctly routing into the septic tank, and not elsewhere on the property.  Often required when property is bought or sold.

Anytime you re-draw you property lines, or take a small piece from the original piece, you are subdividing.  Special planning documents relating to sewage are NECESSARY, required by your Municipality and the DEP.  These Planning Modules are arranged by contacting us.  Do this BEFORE having your survey approved by anyone. 


Most system malfunctions require a repair permit.  Our Sewage Officer will make several visits to your site to advise and guide you in making the appropriate repair.  For your protection, call us before allowing any contractor to begin work. 

Do you have a malfunction in your community?  Call your Municipal office -  They will forward your concern to us.
