12.13.3 Care should be taken to leave adequate area around the joint free of backfill toallow for inspection during testing of the pipeline.12.13.4 Successive layers of backfill of 75 mm thickness may then be placed over andcompacted to a height above the crown of not less than 150 mm. Lightvibrating machinery may be used, but not directly above the pipe.12.13.5 On completion of the surround to the pipe, suitable excavated material may bethen replaced as backfill in 250 mm compacted layers up to the top of thetrench.12.13.6 No heavy compaction equipment to be employed until there is at least 300mmof fill above the crown of the pipe.12.14 Performance requirement of solvent cement joints-12.14.1 Internal Hydrostatic Pressure- when assembled according to thejoint shall withstand an internal pressure of upto and including 0.05 MPa (0.5 bar) for a minimum period of 15 min withoutleakage.12.14.2 Internal Negative Hydrostatic Pressure (Internal Vacuum)- when assembledons, the joint shall withstand aninternal negative pressure (internal vacuum) of up to and including 0.03 MPa(0.3 bar) for a minimum period of 15 min without leakage.12.14.3 Leak tightness of Elastomeric sealing Ring Type socket joints : The method oftesting of joints under positive internal pressure and with Angular deflection isgiven in detail in Annexure-A.12.15 Measurements:The lengths of pipe shall be measured in the running meters nearest to a cm aslaid, lowered and jointed from in side of one manhole to the inside of the othermanhole. The length shall be taken along the centre line of the pipes.12.15.1 All fittings such as bends, junction, etc., which shall not be measuredseparately. Excavation, refilling, shoring and timbering in trenches and cementconcreting where ever required shall be measured separately under relevantitem of work.12.15.2 Security money for testing should be kept at 10 % of the value of the work.After testing of the complete sewerage system to the satisfaction of theengineer in-charge the same shall be released.12.16 Rate12.16.1 The rate shall include the cost of material and labour involved in all theoperation described above including the cost of concrete which shall be paidseparately.Urban Administration & Development Department Page 142
12.17 DWC Pipes for use in underground Sewerage System12.17.1 Technical Specification12.17.1.1 Class SN 8 Structured Double Wall (Non-Smooth External Annular Corrugatedwall & Smooth Internal wall) Polyethylene Piping System for non-pressureunderground Sewerage & Drainage Applications12.17.2 ScopeThis specification covers the requirements for manufacturing, supplying,transportation, handling, stacking, installation, jointing, and testing of Class SN8 Structured Double Wall (Non-Smooth External Annular Corrugated wall &Smooth Internal wall) Polyethylene Piping System for non-pressureunderground Sewerage & Drainage Applications herein after called the DWCPE Piping System.12.17.3 Applicable CodesThe manufacturing, testing at factory, supplying, transportation, handling,stacking, installation, jointing, and testing at sites shall comply with all currentlyapplicable statutes, manuals, regulation, standards & codes. In particular, inaddition to all relevant National Standards, following International standardswith latest revisions shall be referred. If requirements of these specificationsare at variance with any other standards, this particular document shall governthe proceedings.EN13476-1EN13476-3Plastics piping Systems for non-pressure underground drainage and sewerage-Structured-wall piping systems of Polyethylene (PE)Part 1 : General requirements and performance characteristicsPlastics piping Systems for non-pressure underground drainage and sewerage-Structured-wall piping systems of Polyethylene (PE)Part 3 : Specifications for pipes and fittings with smooth internal and profiledexternal surface and the system, Type BOther International Codes / Standards (EN/ ISO) which are integral part ofabove two standards as normative references form a significant portion of thisspecification document.12.17.4 ManufacturingThe DWC PE Piping System of stiffness class designation SN 8 shall confirmto the European Union standards as mentioned above and shall be configuredas per the indicative Cross-sectional Drawing (Fig 3) annexed herewith. Eachpipe shall be coupler (on-line or off-line) and spigot type along with rubbersealing ring (as designated under above international specifications).12.17.5 TransportationThe arrangement of loading the pipes in a telescopic manner is advised, i.e.smaller diameters inserted into the next higher sizes of pipes. While loading thepipes onto the truck, care should be taken that the coupler- end should bearranged alternatively in the corresponding layers so as to avoid the damage tothe coupling/ socket ends.Urban Administration & Development Department Page 143
