Section 62-03.1-03-04 - Location of sewage system1. The minimum lot size in which a private treatment system may be installed is forty thousand square feet [3716.00 square meters]. Smaller lot sizes may be approved by the administrative authority if a centralized sewage treatment system is provided or the soil conditions present throughout the lot are such that a second treatment area is able to be installed in the lot. 2. The following table provides for the minimum distances that shall be observed in locating the various components of the treatment system: | Well 100' | Well 100' | Distribution Device | Treatment Area | Property Lines | Building |
| Bldg Sewer | 100 | 50 | - | - | - | - |
| Septic Tank | 100 | 50 | 5 | 10 | 10 | 10 |
| Distribution Device | 100 | 50 | - | - | 10 | 20 |
| Treatment Area | 100 | 50 | 5 | - | 10 | 10 |
| Well 100' | - | - | 100 | 100 | n/a | n/a |
| Well 100' | - | - | 50 | 50 | n/a | n/a |
| Water line (pressure) (suction) | - | - | 10 50 | 10 50 | n/a n/a | n/a n/a |
| Surface Water bodies | n/a | n/a | 100 | 100 | n/a | n/a |
3. All proposed sites for individual sewage treatment systems must be evaluated as to: a. Depth to the highest known or calculated ground water table or bedrock; b. Soil conditions, properties, and permeability; d. The existence of lowlands, local surface depressions, and rock outcrops; e. All legal setback requirements from existing and proposed buildings, propertylines, sewage tanks, soil treatment systems, water supply wells, buried water pipes and utility lines, the ordinary high water mark of lakes, rivers, streams, flowages, and the location of all soil treatment systems and water supply wells on adjoining lots to the proposed soil treatment system, sewage tank, and water supply well; and f. Surface water flooding probability. 4. Privies, septic tanks, and underground treatment means shall not be within two hundred feet [60.96 meters] measured horizontally from the high water level in the reservoir or the banks of tributary streams when situated less than three thousand feet [914.4 meters] upstream from potable water intake structures. Sewage treatment facilities situated beyond three thousand feet [914.4 meters] upstream from intake structures shall be located no less than one hundred feet [30.48 meters] measured horizontally from the high water level in the reservoir or the banks of the tributary streams.
