A site evaluation is required to determine if a property is suitable for the installation of a septic system. The site evaluation also determines the type and size of a system suitable for a property. Sites are evaluated for suitability based on the type and depth of soil, the depth to the water table, slope, location of the system relative to streams, wells, cuts and fills, and parcel size. There must be enough area available to install an initial system and equal area for repair should it later be required. If community sewer is available the property is required to connect to the sewer service.
