Installation of a septic system is guaranteed unless there is a currently valid Sewage Disposal Permit issued by the Environmental Health Services Division for the development proposed on the lot. If a currently valid permit is absent, you may need to consult with a registered consultant to evaluate the lot to determine if such a permit can be issued. These are the key factors that determine if a Sewage Disposal Permit can be issued: - Physical characteristics of the soil - Soil absorption capability - Depth of soil - Depth of limiting condition(s), including high groundwater indicators, fractured rock, bedrock, impermeable soils - Disposal area available for initial and replacement systems - Maintenance of setback requirements - Physical features of the lot in the area and immediately adjacent to the sewage disposal system
