SOIL TREATMENT AREA (SQUARE FEET) REQUIRED = DESIGN FLOW (GAL/DAY) LTAR (GAL/DAY/SF) SOILS ANALYSIS PERFORMED BY GEOTECHNICAL ENGINEERING GROUP SHOWED A AVERAGE PERCOLATION RATE FOR THE THREE TEST HOLES OF 8.3 MIN/INCH. THIS FALLS WITHIN SOIL TYPE 1 ACCORDING TO TABLE 10-1.

THE PERCOLATION RATE AND SOIL DESCRIPTION RESULTS IN A LONG-TERM ACCEPTANCE RATE OF 0.80 GAL/DAY/SQUARE FOOT. THE PERCOLATION RATE FOR THE TEST LOCATIONS AT THE ABSORPTION FIELD OF 5-11 MIN./INCH CONFIRMED THE SAME LTAR AS THE GRADATION. FROM TABLE 10-1 THE SOIL IS CLASSIFIED AS SOIL TYPE 1 AND REQUIRES TREATMENT LEVEL 1. 5. CLEAN OUTS ARE REQUIRED AT ALL BENDS AND AT LEAST EVERY 100 FEET ALONG THE GRAVITY SANITARY SEWER LINE. 6. THE CONTRACTOR SHALL BE RESPONSIBLE FOR INSTALLING ALL WATER TIGHT COMPONENTS, PRIOR TO THE ABSORPTION AREA, TO PREVENT INFILTRATION. 7. TOPSOIL COVER MAY BE VARIED (WITH. 1 FOOT MINIMUM) TO ALLOW LANDSCAPING. 8, INSTALL RISERS AS NECESSARY TO BRING ALL ACCESS POINTS TO WITHIN ONE-HALF FOOT OF FINAL GRADE. 9. LOCATIONS OF ALL. COMPONENTS MAY BE VARIED AS NECESSARY AS LONG AS ALL MINIMUM DISTANCES. AND SLOPES MEET THOSE REQUIRED. 10. PROVIDE POSITIVE DRAINAGE OF SURFACE WATER AWAY FROM ABSORPTION FIELD AREA USING DRAINAGE SWALES AS NECESSARY. 11. THIS DRAWING DOES NOT CONSTITUTE AN OWTS PERMIT. PERMIT MUST BE OBTAINED FROM APPROPRIATE COUNTY OFFICIALS. THE ENGINEER MUST OBSERVE CONSTRUCTED SYSTEM BEFORE BACKFILL AND PROVIDE REPORT TO COUNTY. 12. THIS SYSTEM IS SIZED FOR TYPICAL DOMESTIC WASTES ONLY. BACKWASH OR FLUSHING FLOWS FOR REVERSE OSMOSIS UNITS OR WATER SOFTENERS OR FILTERS SHOULD NOT BE INTRODUCED INTO THIS SYSTEM. 13. INSTALL BLUEBOARD INSULATION OVER SEWER PIPE WHEREVER DEPTH IS LESS THAN 5.0 FEET. - 14. THE ENGINEER SHALL BE CONTACTED FOR SITE INSPECTION PRIOR TO BACKFILLING OF SYSTEM COMPONENTS. 15. THIS SYSTEM IS DESIGNED FOR TYPICAL DOMESTIC WASTES ONLY. OWNER RESPONSIBLE FOR TIGHT PLUMBING FIXTURES. I.E. HISSING TOILETS AND RUNNING WATER IS NOT ACCEPTABLE AND MAY OVERLOAD THE DESIGNED SYSTEM - 16.

ABSORPTION TRENCH SHALL NOT EXCEED 100 FEET IN LENGTH. 2. THE BOTTOM OF THE ABSORPTION TRENCH SHALL BE LEVEL. 3. DRAINAGE DITCHES ARE TO BE PROVIDED ABOVE AND AROUND TRENCH, AS NECESSARY, TO PREVENT SURFACE RUNOFF CHANNELIZED FLOW FROM ENTERING THE ABSORPTION AREA. 4. ABSORPTION. TRENCH BOTTOM AND SIDEWALLS MUST BE RAKED TO REMOVE SOIL SMEARS INCURRED DURING EXCAVATION. 5. NO EXCAVATION OF ABSORPTION FIELD IS TO BE DONE DURING WET WEATHER AND USE OF RUBBER TIRE VEHICLES OVER BED AREA IS PROHIBITED TO MAINTAIN GOOD SOIL STRUCTURE. 6. UNSUITABLE MATERIAL EXISTING WITHIN THE TRENCH SHALL BE EXCAVATED AND BACKFILL SHALL CONSIST OF ONSITE SELECT OR PIT -RUN MATERIAL. 10 live� +� !_ a TRENCH I WIDTH = 36' SECTION A,A NOTES: 1. EXCAVATE TRENCHES TO PROPER WIDTH, AND PROPER DEPTH AS REQUIRED BY STATE AND LOCAL CODES. 2. SMOOTH IRREGULARITIES IN THE EXCAVATION. A LEVEL, FLAT SURFACE IS REQUIRED. 3. ASSEMBLE ARC LEACHING CHAMBERS AND UNIVERSAL ENDPLATES TOGETHER IN TRENCHES). 4. INSTALL UNIVERSAL END CAP AND SECURE IN PLACE WITH BACKFILL. 5.
