Phase II - System Design (NOID Application)


Once the site and soils evaluation has been completed and approved, a report will be provided. The report will include a description of the soils and the soil absorption rate (SAR). Any limiting conditions will also be noted. The SAR, along with the number of bedrooms and fixture units in the proposed dwelling, is used to determine the minimum design parameters of the septic system.
