THE PAVILION BUILDING AND SEPTIC LOCATION SHOWN IS ONE OF MANY POSSIBLE LAYOUTS, HOWEVER ANY VARIATION FROM THIS PLAN MUST BE APPROVED BY THE ENGINEER OF RECORD, AND ALL APPLICABLE REGULATORY AGENCIES.\u003Cbr>2. ALL CONSTRUCTION METHODS AND MATERIALS, SHALL BE IN ACCORDANCE WITH THE STANDARDS AND POLICIES OF THE LOCAL HEALTH DEPARTMENT AND THE STATE OF CONNECTICUT DEPARTMENT OF HEALTH PUBLIC HEALTH CODE SECTIONS 19-13-B103A THROUGH 19-13-B103F.\u003Cbr>3. THE PURPOSE OF THE PROPOSED SEPTIC SYSTEM IS TO DISPOSE OF DOMESTIC SEWAGE  CONSISTING OF WATER AND HUMAN EXCRETIONS OR OTHER WATERBORNE WASTES INCIDENTAL TO THE OCCUPANCY OF A RESIDENTIAL BUILDING AND NOT TO BE USED FOR WASTE WATER FROM WATER SOFTENING EQUIPMENT, WATER FROM CELLAR OR FLOOR DRAIN~~S~~ OR SURFACE WATER FROM ROOFS, PAVED SURFACES OR YARD DRAINS.\u003Cbr>4. THE LIQUID CAPACITY OF A SEPTIC TANK SHALL BE INCREASED WHENEVER A BUILDING  CONTAINS A GARBAGE GRINDER OR LARGE CAPACITY BATHTUB IN ACCORDANCE WITH THE FOLLOWING: GARBAGE GRINDER: ADD 250 GALLONS TO REQUIRED CAPACITY OF THE SEPTIC ~~  ~~TANK. GARBAGE GRINDERS ARE NOT RECOMMENDED FOR USE WITH SUBSURFACE SEWAGE  DISPOSAL SYSTEMS. LARGE TUB: 100 TO 200 GALLON TUB: ADD 250 GALLONS TO REQUIRED  CAPACITY OF SEPTIC TANK. OVER 200 GALLON TUB: ADD 500 GALLONS TO REQUIRED CAPACITY \u003Cbr>OF SEPTIC TANK. \u003Cbr>5. THERE ARE NO APPARENT SEPTIC SYSTEMS WITHIN 75' OF THE PROPOSED WELL, AND NO WELLS WITHIN 75' OF THE PROPOSED SEPTIC SYSTEM.\u003Cbr>6. FUEL OIL TANKS (IF ANY) SHALL BE INSTALLED INSIDE THE PROPOSED BUILDING. \u003Cbr>7. THE CONTRACTOR SHALL VERIFY ALL DIMENSIONS AND ELEVATIONS SHOWN ON THE PLAN\u003Cbr>PRIOR TO COMMENCING CONSTRUCTION. ANY DISCREPANCIES SHALL BE REPORTED TO THE ENGINEER WHO WILL HAVE FINAL SAY ON ANY ADJUSTMENTS.\u003Cbr>8. THE LEACHING AREAS SHALL BE DELINEATED AND PROTECTED FROM HEAVY EQUIPMENT TRAFFICKING OR STOCKPILES THROUGHOUT THE CONSTRUCTION PERIOD. LEACHING AREAS SHALL BE PROTECTED AT ALL TIMES FROM SURFACE WATER RUNOFF BY APPROPRIATE GRADING. SURFACE WATER RUNOFF SHALL NOT BE PERMITTED TO ENTER ANY PART OF THE LEACHING SYSTEM.\u003Cbr>9. RESERVE AREA NEED NOT BE PREPARED AT THIS TIME (EXCEPT WHERE NOTED OTHERWISE) BUT MAY REQUIRE SELECT FILL AND A DESIGN BY A PROFESSIONAL ENGINEER, IF UTILIZED.\u003Cbr>10. THE PAVILION AND SEPTIC SYSTEM ARE TO BE STAKED OUT BY A LICENSED LAND SURVEYOR.\u003Cbr>11. ALL PIPING WITHIN 25 FEET OF A CURTAIN DRAIN, FOOTING DRAIN, OR WELL SHALL CONFORM TO TABLE 2C OF THE TECHNICAL STANDARDS FOR THE DESIGN AND CONSTRUCTION OF SUBSURFACE SEWAGE DISPOSAL SYSTEMS PER SECT. 19-13-B103 . NO LOOSE OR OPEN  JOINTED, PERFORATED, SLOTTED PIPE (OR FRENCH DRAIN) MAY BE INSTALLED WITHIN\u003Cbr>FIFTY-FEET DOWN GRADIENT ANY PROPOSED LEACHING AREA.\u003Cbr>12. THE SEPTIC TANK SHALL BE INSTALLED SUCH THAT THE ACCESS COVERS ARE LEFT WITHIN TWELVE INCHES OF THE FINISHED GRADE, IF UNDER LAWN. IF THE DESIGN REQUIRES THAT ACCESS MANHOLES BE CONSTRUCTED DUE TO THE DEPTH OF THE TANK, THEY SHALL BE PLACED OVER THE INLET, OUTLET AND CENTER BAFFLES AND EXTENDED TO WITHIN TWELVE INCHES OF FINISHED GROUND LEVEL (OR TO FINISHED GRADE IF LOCATED WITHIN ANY PAVED AREA. THE SEPTIC TANK AND PUMP CHAMBER SHALL BE INSTALLED ON A COMPACTED SAND BED A MINIMUM OF 6 INCHES THICK.\u003Cbr>13. ALL PIPING BETWEEN HOUSE AND SEPTIC TANK SHALL BE CAST IRON (HUBLESS OR BELL AND SPIGOT) ASTM A74, DUCTILE IRON ANSI A21 .51, PVC SCHEDULE 40, ASTM D 1785 OR EXTRA STRENGTH PVC AWWA C-900 75-100 PSI, OR APPROVED EQUAL. MINIMUM SLOPE FOR A 4\" PIPESHALL BE 1/4\" PER FOOT. MINIMUM SLOPE FOR A 6\" PIPE SHALL BE 1/8\" PER FOOT.\u003Cbr>14. ALL PIPING BETWEEN THE SEPTIC TANK AND THE LEACHING AREA SHALL BE TIGHT JOINTED FOUR INCH DIAMETER PVC ASTM D-3034 OR APPROVED EQUAL, UNLESS OTHERWISE SPECIFIED. PIPE SHALL BE SET ON A MINIMUM SLOPE OF 1/8\" PER FOOT.\u003Cbr>15. DISTRIBUTION BOXES SHALL BE MODEL \"DB-3\" AS MANUFACTURED BY CONNECTICUT PRECAST INC. , OR APPROVED EQUAL.
