Note: All measurements are in feet.
1. These distances have been determined for use in clay and loam soils only. The minimum distances required for use in sand or other types of soil shall be determined for the proposed private sewage disposal system and approved by this Department. Such approval will be given where the Department determines that the soil will provide treatment of the sewage.
2. The building sewer may be located to within 10 feet of a well or suction line from the pump to the well when cast iron pipe with mechanical joints or Schedule 40 PVC pipe with water-tight joints is used for the building sewer.
3. See Section 310. Septic system components shall maintain a minimum separation of 25 feet from drainage or stormwater detention easements for surface drainage or water collection or 15 feet from a conduit or pipe.
4. The minimum separation distance shall be 200 feet if the special waste holding tank meets the criteria of a potential secondary source as defined.

TABLE VIII: VARIANCES POSSIBLE FOR SEPTIC SYSTEMS TO SERVE NEW CONSTRUCTION.
Note: When circumstances exist which make impractical full compliance with the requirements of the Ordinance, an applicant may request a variance. Each variance request is reviewed in conjunction with the specific on-site conditions. It should not be assumed that a variance will automatically be granted. The following table provides general guidelines for variances which may be considered for private sewage disposal systems for new construction:
