After expelling the air through the air outlet, the stop cock shall beclosed and water level in the funnel shall be raised to 2.5 m above the invert atthe upper end.13.11.4.1 Water level in the funnel is noted after 30 minutes and the quantity of waterrequired to restore the original water level in the funnel is determined.13.11.4.2 The pipe line under pressure is then inspected while funnel is still in position.There shall not be any leaks in the pipe or joints (small sweating on the pipesurface is permitted).13.11.5repaired or re-laid as required and tested again.13.11.6 In testing pipe lines, a seepage allowance of 2.5 liters per kilometer per hourper centimeter diameter of the pipe shall be permissible.13.11.7 Ex filtration test for detection of leakage shall be carried out at a time when theground water table is low.13.11.8 Air testing shall be done particularly in large diameter pipes when the requiredquantity of water is not available for testing. It is done as per procedure given inCPHEEO manual.13.12 Back filling of trenches:13.12.1 The method of backfilling to be used shall vary with the width of trench, thecharacter of material excavated, the method of excavation and degree ofcompaction required.13.12.2 In open country, it shall be sufficient to mound the trench and after naturalsettlement return to re-grade the areas.13.12.3 In developed streets, it shall be compacted to minimize the load.13.12.4 Soft material screened free from stones or hard substances shall first be usedand hand pressed under and around the pipes to half the height.13.12.5 Similar soft material shall then be put up to a height of 30 cm. above the top ofpipe and this will be moistened with water and well rammed.13.12.6 The remaining trench can be filled with hard material, in layers each notexceeding 60 cm. At each stage the filling shall be well rammed, consolidatedand completely saturated with water and then only further filling shall becontinued.13.13 Measurement13.13.1 Reinforce cement concrete pipes should be measured according to the workactually done and no allowance should be made for any waste in cutting to theUrban Administration & Development Department Page 156
exact length required. The measurement for pipes should be in running metersnearest to a cm. as laid or fixed, from inside of one manhole to the inside of theother manhole.13.13.2 The length shall be taken along with center line of the pipes overall fittings suchas bends, collars, junctions etc which shall not be measured separately.13.13.3 Excavation, refilling, shoring and timbering in trenches and cement concretingwherever required shall be measured separately under relevant items of work.13.14 Rates:13.14.1 The for providing, laying and jointing of RCC pipes shall be inclusive of the costof collars/Rubber rings, jointing material, testing and the extra excavationrequire for ordinary bedding of pipes and also for collars and pipe sockets ifany.13.14.2 Any damage caused to the pipe line during the execution of work or duringcleaning/Testing of the pipe line, contractor shall replace the damaged pipe lineand retest the same at its own cast. No extra payment shall be made to thecontractor for this work.13.14.3 Water for testing of the pipe line shall be provided by the contractor at his owncost.Urban Administration & Development Department Page 157
