If you are building a new home, planning an addition, adding an accessory dwelling unit, or dealing with a failing system, these answers explain the basics before you move forward.
Once approved by the State, a design expires after four years. If the septic system is under active construction when the approval expires an extension can be requested.
A test pit is a hole dug into the ground by an excavator to a depth of about 5 feet. This allows the designer to examine the soils for their suitability to sustain a leachfield.
A perc test determines the rate at which water percolates through the soil and is one of the determining factors of leachfield sizing.
Yes. Constructing an ADU or adding a bedroom to your existing home increases the amount of sewage created by the residence. The State requires a new design be submitted for approval to ensure that the property can dispose of the increased sewage load and there is enough room on the property to replace the septic system. In many cases, as long as the property can sustain a new system that meets current regulations at the time the bedroom or ADU is constructed, they will allow you to “tie into” the existing system and not construct the new system.
Depending on what needs to be repaired, you may need to work with a designer to make that repair. One exception is the replacement of your septic tank. As long as the new tank is larger or of equal size to the old one, you do not need a septic permit. It is recommended to talk to the Town’s Building Inspector or Health Officer before attempting any repair of your septic system. Your town may have regulations more strict than the State.
Fees are based on the type and complexity of the design. The notes below explain what is typically included and which outside costs are separate.
A basic design will typically cover most residential needs, including failed systems, additions, and new builds.
The basic design fee covers site visits, test pit logging, topographic survey, data processing, design, Town and State applications, and any requested changes by either Town or State agencies. This also includes as-built designs that are often necessary to achieve operational approval from the State.
Commercial designs are often more complicated than residential designs. Like the basic residential design, this fee covers site visits, test pit logging, topographic survey, data processing, design, Town and State applications, and requested changes by either Town or State agencies.
Commercial fees may also include as-built designs that are necessary to achieve operational approval.
