The Sewage Enforcement Officer then examines the soil layers in the probe hole to determine the type of soil located on the property and if any "limiting zone" (i.e. rock, water table, etc.) exists. At this point, the Sewage Enforcement Officer determines at what depth the percolation holes should be dug and their locations.

The application and township permit fees range from $75.00 to $225.00 varying with the township. The excavation of a probe and a set of percolation test holes can range between $300.00 to $600.00. A deposit of the above noted fees is required prior to the tests being performed by the Sewage Enforcement Officer and excavation by our crews.

After the completion of the probe and percolation tests, the results, as interpreted by the Sewage Enforcement Officer, would determine the size and type of system to be installed. There are various types of systems and prices ranging as follows:

Standard Inground Septic System:
This septic system is installed where a "no limiting zone" exists and the perc rate is between 6 and 59. The price for this type of septic system, including the permit preparation work and fees, design of the system, and installation could range between $4,800.00 to $6,000.00. This price range could vary depending upon the size of the septic system, the outlet line specifications, and any additional excavation due to rock or excess water.

Standard Inground Pressure Dose System:
This septic system is installed where a "no limiting zone" exists and the perc rate is between 60 and 90. This system requires a septic tank and a dose tank with a submersible pump. The price for this type of septic system, including the permit preparation work and fees, design of the system, and installation could range between $6,500.00 to $8,500.00. This price range could vary depending upon the size of the septic system, the pump size necessary to correctly dose the system, the outlet line specifications, and any additional excavation due to rock or excess water.

Elevated Sand Mound Pressure Dose System:
This septic system is installed where a "limiting zone" exists and the perc rate is between 90 and 120. The system is installed above ground with D.E.P. approved sand used in the bed. Additional fill and topsoil would be hauled to the site to cover the system and grade it into the surroundings. The price for this type of septic system, including the permit preparation work and fees, design of the system, and installation could range between $10,000.00 and $12,000.00. This system also requires a dose tank with submersible pump. The cost varies widely due to the required pump size and the amount of additional fill that may be necessary.

Due to the amount of variations in the systems, it is necessary to perform both the probe and perc tests to determine the exact pricing. All of the aforementioned costs are general estimates. After final determination by the Sewage Enforcement Officer, a more detailed estimate can be provided.
