What do I need to do if I have a failing system that must be replaced?
  • The first step is to have a soil test conducted by a certified soil tester (soil / site evaluator). This was formerly referred to as a "perk test", but is now known as a "detailed soil morphological evaluation." This test involves digging at least 3 soil pits in a triangular shape so that the soil inside the triangle should be very similar to the soil observed in the test pits. The soil test identifies a suitable area to install a private onsite waste disposal system and determines the amount (inches) of suitable soil underneath the system.
  • The second step is to have a plumber, engineer or system designer design a private onsite wastewater treatment system (POWTS), formerly called a septic system, based on the findings of the soil test and the proposed use of the property. The use of the property is important because a residence will not have the same size system requirements as a commercial use and a 4 bedroom residence will not have the same size system requirements as a 2 bedroom residence. At this point you should also discuss the system sizing so the system can accommodate anticipated future additions to the residence.
  • State Plan Approval is required before the county can issue any sanitary permit for a mound, at-grade, in-ground pressure, or holding tank system. The plumber, engineer, or system designer takes care of this step for the property owner. The length of time to receive State Plan Approval varies by season and the workload of the state. It can range from several days to several weeks. If the system was designed by an engineer or system designer you will need to decide on a plumber to install the system. A system designed by a plumber is required to be installed by that plumber.
  • After the plans are approved by the state, the installing plumber will apply for the sanitary permit at the county level. Typically the county review and action on a sanitary permit application will take less than 1 week.
