AutoCAD SHX Text
PRIOR TO ANY CONSTRUCTION, THE CONTRACTOR SHALL TELEPHONE MISS DIG (1-800-482-7171) FOR THE LOCATION OF UNDERGROUND FACILITIES AND SHALL ALSO NOTIFY REPRESENTATIVES OF ANY OTHER FACILITY, LOCATED IN THE VICINITY OF THE WORK, WHICH MAY NOT BE HANDLED BY MISS DIG. CONTRACTOR SHALL NOTIFY THE WASHINGTON TOWNSHIP DEPARTMENT OF PUBLIC WORKS 48 HOURS PRIOR TO START OF CONSTRUCTION AND REQUEST AN INSPECTION OF THE PROJECT. PRIOR TO CONSTRUCTION, THE CONTRACTOR SHALL ATTEND A PRE-CONSTRUCTION MEETING AT A TIME AND PLACE AS ARRANGED BY THE TOWNSHIP, IN WHICH VARIOUS UTILITY COMPANIES AND GOVERNMENTAL AGENCY REPRESENTATIVES WILL BE PRESENT. PRIOR TO CONSTRUCTION, THE CONTRACTOR MUST HAVE IN HIS POSSESSION A COPY OF A PERMIT TO CONSTRUCT A CONNECTION TO, OR AN EXTENSION OF, THE SANITARY SEWER SYSTEM, FROM THE WASHINGTON TOWNSHIP DEPARTMENT OF PUBLIC WORKS. ALL CONSTRUCTION PROCEDURES AND MATERIALS USED ON THIS PROJECT SHALL CONFORM TO WASHINGTON TOWNSHIP CURRENT STANDARDS AND SPECIFICATIONS. ALL SEWERS OVER 24" DIAMETER SHALL BE SUBJECTED TO INFILTRATION OR EXFILTRATION TESTS. UNLESS WAIVED BY THE TOWNSHIP, ALL SEWERS OF 24" DIAMETER OR SMALLER WHERE THE GROUND WATER LEVEL ABOVE THE TOP OF THE SEWER IS OVER 2 FEET SHALL BE SUBJECTED TO AN INFILTRATION TEST INSTEAD OF AIR TEST. MANHOLE MANUFACTURER SHALL INSTALL 1/2" DIA. GALVANIZED STEEL PIPE AND CAP AT PIPE CROWN, FLUSH WITH OUTSIDE WALL AND EXTENDING 3" INSIDE. CONTRACTOR TO SEAL AFTER COMPLETION OF TESTS. CLEAN STONE TO BE PLACED ON OUTSIDE OF MANHOLE AT SITE CLEAN STONE TO BE PLACED ON OUTSIDE OF MANHOLE AT SITE TUBE TO PREVENT SITE TUBE FROM BECOMING PLUGGED. PRIOR TO AIR TEST, GROUNDWATER ELEVATION MUST BE DETERMINED BY BLOWING AIR THROUGH SITE TUBE TO CLEAR IT, THEN CONNECTING A CLEAR PLASTIC TUBE TO THE PIPE NIPPLE. SUSPEND CLEAR PLASTIC TUBE VERTICALLY INSIDE MANHOLE AND OBSERVE GROUNDWATER ELEVATION AFTER EQUALIZATION. NO SEWER INSTALLATION SHALL HAVE AN INFILTRATION RATE EXCEEDING 100 GALLONS PER INCH DIAMETER OF PIPE PER MILE OF PIPE PER 24 HOUR PERIOD, FOR ANY PART OF THIS PROJECT INCLUDING MANHOLES. ONLY MODIFIED GROOVE TONGUE, ASTM C-425, ASTM C-443, O-RING, UNILOC, AMVIT, NOBEL, RING-TITE, FLUID-TITE OR EQUIVALENT AS APPROVED BY WASHINGTON TOWNSHIP MAY BE USED FOR SEWER JOINTS IN REINFORCED CONCRETE PIPE. ALL JOINTS SHALL MEET REQUIREMENTS OF ASTM C-425 OR C-443. AT ALL CONNECTIONS TO AN EXISTING SEWER OR TO EXTENSIONS THERETO, A WATERTIGHT PLUG SHALL BE PROVIDED TO PREVENT ANY FLOW FROM ENTERING EXISTING SYSTEM UNTIL ALL TESTING HAS BEEN COMPLETED AND THE SYSTEM HAS BEEN APPROVED BY THE TOWNSHIP, UNLESS WAIVED BY THE TOWNSHIP. A TEMPORARY 12 INCH DEEP SUMP SHALL ALSO BE PROVIDED IN THE FIRST MANHOLE ABOVE THE CONNECTION WHICH WILL BE FILLED IN AFTER SUCCESSFUL COMPLETION OF ANY INFILTRATION TEST UP TO THE STANDARD FILLET PROVIDED FOR THE FLOW CHANNEL. ALL SANITARY SEWER UNDER 18" DIAMETER SHALL BE SDR 26 PVC PIPE PER ASTM D-3034 WITH GASKETED OR GLUED SPECIAL JOINTS PER ASTM D-3212 OR D-2564, RESPECTIVELY. WHERE PVC MAIN LINE IS USED, BUILDING LEADS, FITTINGS AND RISERS SHALL BE 6" PVC SOLID WALL SDR 23.5 PER ASTM D-3034 WITH GLUED JOINTS. SEWER WYE OPENINGS SHALL CONTAIN FACTORY INSTALLED PREMIUM JOINT MATERIAL OF THE TYPE IDENTICAL TO THAT OF THE BUILDING LEAD PIPE USED. BUILDING LEADS TO BE FURNISHED WITH REMOVABLE AIRTIGHT AND WATERTIGHT STOPPERS. GASKETED JOINTS MAY BE USED UNDER SPECIAL CIRCUMSTANCES WITH APPROVAL OBTAINED FROM THE DIRECTOR OF PUBLIC WORKS. IF BUILDING LEADS LARGER THAN 6" ARE REQUIRED, THEY SHALL BE PER TOWNSHIP ENGINEERING STANDARDS UNLESS SHOWN OTHERWISE ON THE PLANS. INSTALLATION OF PVC PIPE SHALL CONFORM TO ASTM SPECIFICATION D-2321. NO GROUND WATER, STORM WATER, CONSTRUCTION WATER, DOWNSPOUT DRAINAGE OR WEEP TILE DRAINAGE SHALL BE ALLOWED TO ENTER ANY SANITARY SEWER INSTALLATION. ALL SEWER PIPE SHALL BE INSTALLED IN BEDDING MATERIAL TO 12-INCHES ABOVE THE PIPE, ACCORDING TO THE DETAIL ON THIS SHEET. ALL NEW MANHOLES SHALL HAVE APPROVED FLEXIBLE, WATERTIGHT SEALS WHERE PIPES PASS THROUGH WALLS. MANHOLES SHALL BE OF PRECAST SECTIONS WITH MODIFIED GROOVE TONGUE AND RUBBER GASKET TYPE JOINTS. PRECAST MANHOLE CONE SECTIONS SHALL BE APPROVED MODIFIED ECCENTRIC CONE TYPE. ALL MANHOLES SHALL BE PROVIDED WITH EJ "CAM LOCK" SECURITY OPTION. INTERNAL DROP CONNECTIONS ARE REQUIRED AT NEW MANHOLES WHERE THE OUTLET PIPE IS 18 INCHES OR MORE BELOW THE INLET PIPE. A CONCRETE SLIDE WILL BE REQUIRED ON THE INLET PIPE WHEN THE INLET PIPE IS BETWEEN 3" AND 18" ABOVE THE OUTLET PIPE. ALL MANHOLES WITH AN INTERNAL DROP CONNECTION SHALL BE A MINIMUM OF 5' IN DIAMETER. WHEREVER EXISTING MANHOLES ARE TO BE TAPPED, THE WALL WILL BE CORED AND KOR-N-SEAL FLEXIBLE RUBBER JOINT INSTALLED. EXISTING PIPES TO BE CORED AND A WYE SADDLE USED OF SAME PIPE MATERIAL AS BUILDING LEAD. NEW MANHOLES CONSTRUCTED DIRECTLY ON WASHINGTON TOWNSHIP SEWERS SHALL BE PROVIDED WITH COVERS READING "WASHINGTON TWP SANITARY SEWER." NEW MANHOLES BUILT OVER ANY EXISTING SANITARY SEWERS SHALL HAVE MONOLITHIC POURED BOTTOMS. BRANCH PIPES SHALL HAVE INVERT ABOVE EIGHT-TENTH POINT OF MAIN LINE PIPE. WATERTIGHT CONNECTIONS BETWEEN THE EXISTING PIPE AND NEW MANHOLE SHALL BE REQUIRED. 18" MINIMUM VERTICAL SEPARATION MUST BE MAINTAINED BETWEEN SANITARY SEWER AND ALL OTHER UNDERGROUND UTILITIES. AIR TESTS OR INFILTRATION/EXFILTRATION AND TELEVISION VIEWING SHALL BE MADE ON ALL NEW SEWER LINES NOT SOONER THAN 3 WEEKS FOLLOWING COMPLETION OF BACKFILL. A DVD OF ALL TELEVISED SEWER LINES SHALL BE SUBMITTED TO THE TOWNSHIP DEPARTMENT OF PUBLIC WORKS FOR THEIR RECORDS WITHIN ONE WEEK OF INSPECTION. THE TOWNSHIP REQUIRES THE FOLLOWING STANDARDS FOR DVDS: 1.) STOP AND TURN TO ALL WYES/TEES; 2.) SLOW OR STOP AT ALL JOINTS, AND ROTATE CAMERA IN PIPES WITH DIAMETERS OF 15 INCHES OR GREATER; 3.) PIPES MUST BE CLEAN BEFORE DVD IS MADE; 4.) NO DVD SHALL BE MADE FOR RECORD UNLESS A TOWNSHIP INSPECTOR IS PRESENT AND OBSERVING. ALL AIR TESTS SHALL CONFORM TO ASTM F-1417 FOR PLASTIC PIPE UNLESS ALTERNATE REQUIREMENTS ARE APPROVED BY THE TOWNSHIP. UNLESS WAIVED BY THE TOWNSHIP, DEFLECTION TESTS SHALL BE PERFORMED ON ALL FLEXIBLE PIPE. THE TESTS SHALL BE CONDUCTED AFTER THE FINAL BACKFILL HAS BEEN IN PLACE AT LEAST 30 DAYS TO PERMIT STABILIZATION OF THE SOIL-PIPE SYSTEM. NO PIPE SHALL EXCEED A DEFLECTION OF 5 PERCENT OF THE INSIDE DIAMETER. IF DEFLECTION EXCEEDS 5 PERCENT, THE PIPE SHALL BE EXCAVATED. REPLACEMENT OR CORRECTION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THE REQUIREMENTS IN THE APPROVED SPECIFICATIONS. THE RIGID BALL OR MANDREL USED FOR THE DEFLECTION TEST SHALL HAVE A DIAMETER NOT LESS THAN 95 PERCENT OF THE BASE INSIDE DIAMETER OR AVERAGE INSIDE DIAMETER OF THE PIPE DEPENDING ON WHICH IS SPECIFIED IN THE ASTM SPECIFICATION D-3034, INCLUDING THE APPENDIX, TO WHICH THE PIPE IS MANUFACTURED. THE TESTS SHALL BE PERFORMED WITHOUT MECHANICAL PULLING DEVICES. ALL SHAFTS, PITS, TRENCHES AND HOLES TO BE LEFT OPEN OVERNIGHT SHALL BE COMPLETELY ENCLOSED WITH SUITABLE FENCING AND ACCEPTABLE LIGHTING SHALL BE PROVIDED. THE CONTRACTOR SHALL PROVIDE A 2" X 4" LOCATION STAKE AT THE END OF ALL HOUSE LEADS 48" BELOW GRADE. IF A MANHOLE IS INSTALLED IN, OR IN BACK OF, A ROAD DITCH THE CONTRACTOR SHALL INSTALL A 16 FT. LONG, 16 GAUGE C.M.P. CULVERT WITH END SECTIONS OF A DIAMETER AS DIRECTED BY THE MACOMB COUNTY DEPARTMENT OF ROADS, WASHINGTON TOWNSHIP DEPARTMENT OF PUBLIC WORKS, OR WHOEVER HAS JURISDICTION, IN THE DITCH IN FRONT OF THE MANHOLE AND SHALL BACKFILL WITH 22A AGGREGATE.
