July ll, 1994 <br /> <br />APPLICANT: <br />SITE NUMBER: <br /> <br />STANDARD SYSTEM CONSTRUCTION DETAIL SHEET <br /> <br />MARY FRAZIER <br />94-1766 <br /> <br /> Your site has been found suitable for a STANDARD ON-SITE SEWAGE DISPOSAL <br />SYSTEM. The following construction specifications shall apply to the installa- <br />tion of your septic system. <br /> <br />The septic tank shall have a minimum liquid capacity of 1000 <br />gallons. <br /> <br />The projected daily sewage flow for this project is calculated at <br />450 qallons per day. Based on soil conditions observed on this <br />site, the disposal field will be sized at 150 lineal feet per 150 <br />gallons of projected daily sewage flow. A minimum of 450 lineal <br />feet of disposal field will be required for your proposed develop- <br />ment. The disposal trenches are constructed two (2) feet wide and <br />on minimum ten (10) foot centers and with no line exceeding 125 <br />feet in length. The trenches and perforated pipe are installed <br />level (~1") and contoured to follow the natural ground surface. <br /> <br />The disposal field shall be constructed with serial distribution <br />with a minimum trench depth of 24 inches and a maximum trench <br />depth of 24 inches. There must be at least 12 inches of backfill <br />over the top of the gravel, measured from the natural ground <br />surface. <br /> <br /> This approval is site specific to the area tested and the septic system <br />must be located in the immediate area of the test pits unless otherwise autho- <br />rized by this office. A new site evaluation may be required if the system is <br />proposed for a different area on the property. <br /> <br />SPECIAL CONDITIONS: <br /> Construct the drainfields within the immediate area of the soil test <br /> pits and no farther downslope. Avoid the northwest corner of the <br /> property and the associated concave land-form/drainage swale. Observe <br /> all the normal setback and separation distances as outlines by the <br /> enclosed setback list. Use care not to alter'the natural topsoil prior <br /> to drainfield construction. <br /> <br />THIS IS NOT A PERMIT TO INST~?~. THE SEPTIC SYSTEM. DO NOT INSTaTe. THE SYSTEM <br /> <br />UNTIL A VALID PERMIT HAS BEEN ISSUED BY THIS OFFICE. <br /> <br /> <br />
