~RESS~R~IZED DISTRIBU~..~ON EY~CONSTRU.~T~ON DETAIL April 1S, 1992 kP~LICANT: DONALD ~ORNER SITE NUMBER: 13394 Your si~e has been found suitable for a PREgSURIZED BISTR~BUTION ALTERNATIVE SEWAGE DISPOSAL SYSTEM. The following construction specifications shall apply to the installation of your septic system. 1. The septiG tank shall have a minimum liquid capacity of 10~ 9allons. The projected daily ~ewage flew for this project is calculated at 450 ~allons p~r day, Baaed on soil conditions observed on '=his site, the disposal field wil% ~e sized a~ 7~.llneal. ~eet D~r 150 ~allons of pr~jmcted daily sewage ~low. A minimum of ~ linpal f~et of disposal field will be required for your proposed develop- ment. The disposal trenches ate constructed two (2) feet wide and on minimum ten {10) foot c~nters and with no line exceeding 1~5 ~eet in length. The trenche~ and perforated pipe a~ installed level (~1") and contoured t~ fellow the natural ground surface. The disposal field piping is minimum two (~) inch pressure piping, with a minimum 160 p~i rating. The sidewalls of th~ disposal trenches and top of the falter material Shall be lined with filter fabric. The disposal field shall be constructed with e~.~al distribut~O~ with a minimum trench de~th of ~.~ inQhes and a maximum trench depth of l~_~_~nches, There mu~t be at least .l~ inch~s of back£ill ove~ the top of the ~ravel, measured from the natural ground surface. An effluent lift pump Or siphon which is sized to provide a minimum residual head Of five (5) feet at the most distant orifice is requited A cap~ing fill i~ required with this system. The system shall be cons'tructed as indicated on the attached Capping Fill construction detail shee~. This approval is site specific to the area tested and the ~eptic system must be located is the immediate area of the test pits unless otherwise authorized by thim office. A new site evaluation may be required if the system is proposed for a different area on the proper~y. SPECIAL CONDITIONS~ The drainfields must be constructed within the immediate area of the ~est pitB, preferably within the area of the mo~t easterly pit. Con- struct the d=ainline trenches only into the natural undisturbed topsoil. ~NTI~,AVALID mERMI~ HAS BEEN I~$UE~,.~y THIS ~F~ICE.
