october 19, 1994 <br /> <br />APPLICANT; <br />SIT~ NUMB~R~ <br /> <br />STANDB3%D SYSTEM CONSTRUCTION DETAIL SHEET <br /> <br />CHUCK BAKER <br />94-3493, PARCEL C, 3.31 ACRES. <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 />1. 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 gallons per da~. Based on soil conditions observed on this <br />site, the disposal field will be sized at 150 lineal feet Der 150 <br />gallons of projected daily sewage flow. A minimum Of 450 lineal <br />.~et 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 /> An effluent lift pump may be necessary to construct the disposal field <br />in the approved area and at the correct depth. <br /> <br /> A g~oundwater interceptor is required as part of this system. This <br />interceptor trench must be constructed a minimum twelve (12) inches wide by 42 <br />inches deep with 36 inches of clean gravel placed over a four (4) inch smooth <br />wall perforated pipe. The interceptor must be located at least ten (10) feet <br />upslope from the disposal field and must discharge through a watertight, non- <br />perforated pipe beside or below the disposal field. A separation of 25 feet is <br />required from the septic tank if the tank is located upslope of the groundwa- <br />ter interceptor. <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 only on convex landforms within the area of <br /> the soil test pits. At least fifty feet upslope of the public road-way, <br /> road ditch and seasonal drainage ways. Soil conditions are marginal for <br /> standard system construction. Use care not to alter the natural topsoil <br /> prior to drainfield construction. A pre-construction field stakeout is <br /> recommended to establish the elevations and locations of the individual <br /> drainfield lines of both systems prior to siting wells and all excava- <br /> tions. Refer to the enclosed stakeout procedure and the setback list for <br /> details to complete the stakeout. The lists of licensed septic system <br /> installers and consultants who can assist with the stakeout are included <br /> for your Convenience. <br /> <br />THIS IS NOT A PERMIT TO INSTALL THE SEPTIC SYSTEM. DO NOT INSTALL THE SYSTEM <br />UNTIL A VALID PERMIT HAS HEEN ISSUED BY THIS OFFICE. <br /> <br /> <br />
