April 27, 1994 APPLICA/~T~ SITE NUMBER: STANDARD SYSTEM CONSTRUCTION DETAIL SHEET LARRY FJ~UDELL 94-1575, PARTITION, 3 OF 6 ACRES. NORTH PO T/L 200 Your site has been found suitable for a STANDARD ON-SITE SEWAGE DISPOSAL SYSTEM. The following construction specifications shall apply to the installa- tion of your septic system. 1. The septic tank shall have a minimum liquid capacity of 1000 gallons. 2. The projected daily sewage flow for this project is calculated at 450 gallons per day. Based on soil conditions observed on this site, the disposal field will be si~ed at 15O l%neal feet Der 150 qallons of projected daily sewage flow. A minimum of 450 lineal feet of disposal field will be required for your proposed develop- ment. The disposal trenches are constructed two (2) feet wide and on minimum ten (10) foot centers and with no line exceeding 125 feet in length. The trenches and perforated pipe are installed level (±1") and contoured to follow the natural ground surface. 3. The disposal field shall be constructed with serial distrib~tiqq with a minimum trench depth of 24 inches and a maximum trench depth of 24 inches. There must be at least 12 inches of backfill over the top of the gravel, measured from the natural ground A groundwater interceptor is required as part of this system. This interceptor trench must be constructed a minimum twelve (12) inches wide by 42 inches deep with 36 inches of clean gravel placed over a four (4) inch smooth wall perforated pipe. The interceptor must be located at least ten (10) feet upslope from the disposal field and must discharge through a watertight, non- perforated pipe beside or below the disposal field. A separation of 25 feet is required from the septic tank if the tank is located upslope of the groundwa- ter interceptor. An effluent lift pump may be necessary to construct the disposal field in the approved area and at the correct depth. This approval is site Specific to the area tested and the septic system must be located in the immediate area of the test pits unless otherwise autho- rized by this office. A new site evaluation may be required if the system is proposed for a different area on the property. SPECIAL CONDITIONS: Construct the drainfields within the immediate area of the test pits and no farther downslope. Avoid the concave landform. A pre-permit field stakeout will be necessary to establish the location and elevations of the individual drainfield lines for both system. Refer to the stakeout procedure and the setback list for details to complete the stakeout. Note, especially the separation distance between the septic tank and curtain drain depending upon whether the tank is above or below the curtain drain. Siting wells should be deferred pending the stakeout review. Soil conditions are marginal for standard system construction so use care not alter the natural topsoil prior to drainfield installation. THIS IS NOT A PEEMIT TO INSTALL THE S~PTIC SYSTEM. DO NOT INSTALL THE SYSTEM UNTIL A VALID PERMIT HAS B~N ISSUED BY THIS OFFICE.
