described in the several clauses relating thereto and so that the inverts may be at the levels given
on the section . In bad ground , the Engineer may order the contractor to excavated to a greater
depth than shown in the drawings and fill up the excavation to the level of the sewer with concrete
; sand , gravel or other materials . For such work the contractor shall be paid extra at the rates
laid down such works in the schedule , if the extra work was ordered by the Engineer in writing
.But if the contractor should excavate the trench to greater depth than is required without a
specific order to that effect in writing of the Engineer , the extra depth shall have to be filled up
with concrete at the contractor‟s own cost t o the requirements and satisfaction of the Engineer.
REFILLING
After the sewer or other work has been laid and proved to be water-tight , the trench or other
excavation shall be refilled . Utmost care shall be taken in doing this ,so that no damage shall be
caused to the sewer and other permanent works . Filling in he trenches up to 50cm above the
crown of the sewer shall consist of the finest selected materials placed carefully and consolidated .

After this has been laid , the trench and other excavation, each layer being watered and
consolidated .
CONTRACTOR SHALL RESTORE SETTLEMENT AND DAMAGES
The contractor shall at his own cost make good promptly , during the whole period the work are
in hand, any settlement that may occur in the surfaces of roads , beams , footpaths, gardens open
spaces etc . whether public or private caused by his trenches or his other excavations and he shall
be liable for any accidents cased thereby .He also shall, at his own expense and charge repair and
make good any damage done to buildings and other properties.
DISPOSAL OF SURPLUS
The contractor shall at his own cost dispose within the site or as directed all surplus excavated materials
not required to be used on the work .
SHORING
The contractor shall at all times support efficiently the sides of trenches and other excavations by
suitable timbering , piling , sheeting etc . Trenches shall be close timbered in loose or sandy strata
and below the surface of the sub – soil water table .
All timbering , sheeting and piling with their wailings and supports shall be of adequate
dimensions and strength and fully braced and strutted so that there is no risk of collapse or
subsidence of the walls of trenches . The contractor shall be held accountable and responsible for
the sufficiency of all timbering , bracing , sheeting and piling used for all damages to persons and
property resulting from the improper quality , strength , placing , maintenance or removing of the
same
BAILING OUT WATER
The contractor shall at all times, during the progress of work, keep trenches and excavations free
from which shall be disposed off by him in a manner as will neither cause injury to public nor to
public or private property nor to the work completed or in progress nor to the surface of any
roads or streets nor cause any interference with the use of the same .
PROTECTION OF EXISTING SERVICES
All pipes, water mains, cables etc. met in the course of excavation shall be carefully protected and
supported.
CONCRETING
All pipes at shallow road crossings and made –up ground shall be laid on a bed of 6”(150mm)
concrete with one part of cement , four parts of sand and eight parts of stone metal of

LAYING AND FIXING
Pipes are to be cut to size and threaded with standard GI threading die . Pipes and fittings shall be
jointed using Teflon tape as thread sealant. Pipes and fittings can be tightened by hand also to achieve
leak –proof joint. Pipes shall be fixed by means of holder bat clamps keeping them 12mm off walls for easy
maintenance. Pipes running on roof slabs shall be suitably supported blocks and to be projected
from ultra violet radiation
TESTING
Pipes shall be tested to a hydrostatic pressure of 10 kg/sq cm and pressure shall be maintained for
at least eight hours without appreciable drop in pressure . In addition to sectional testing of water
supply pipes , the contractor shall test the whole of the installation to the entire satisfaction of
the Engineer.
PVC PIPES
LAYING AND JOINTING
For PVC pipes ,pasted joints are preferred .The socket length should be 11/2 times the outer
diameter for size above 110mm diameter . The surface to be glued should be thoroughly scoured
with dry cloth and preferably chamfered to 30o.Slovent cement is to be applied evenly with a
brush outside surface of the spigot of one pipe and to the inside surface of the socket of the
other . The spigot end should then be inserted immediately into the socket should be wiped out
at once with a clean dry cloth . Jointing should be carried out quickly , taking not more than one
minute to completed joint should not be disturbed for at least 5 minutes . Gluing should be
avoided in rainy or foggy weather to avoid water contamination of the solvent cement . Pipes
should be supported at distance of 1.20 m for vertical runs with appropriate MS clips and support
blocks or wooden plugs fixed on walls , floors or ceiling . Holder bat clamps are to be used to keep
pipes 12mm clear off walls.
TESTING
Pipes should be tested to a hydrostatic test pressure of 3.5kg/sq cm in sections of lengths. Pressure should
be maintained for 8 hours without appreciable drop. In addition to sectional testing of pipes , the
contractor shall test the entire installation to the entire satisfaction of the Engineer.
CHLORINATED POLY VINYL CHLORIDE PIPES (CPVC PIPES)
The pipe may cut to the required lengths using circular tubing cutters, Ratchet type cutters or
chop saws .The cuts shall be square . Burrs and fillings shall be removed from outside and inside
the pipes using a chamfering tool
For jointing CPVC pipes special solvent cement is required. The surfaces are to be dry before solvent
cement shall not be allowed puddle in the fitting and pipe assembly . The pipe may then be
rotated to one quarter to half turn while inserting into the fitting socket. When the pipe end is
seated it may hold in place for ten second s to allow the joint to set. Teflon tape may be used as
thread sealant.
Water testing to a pressure of 10kg/cm2 may be carried out for CPVC piping system . Air testing
shall not be done

The installation of PP pipes may be carried out similar to metal pipes . The pipes may be cut to
the desired length using special cutters , the cuts being perpendicular to the axis.
Jointing of PP pipes may be done using Fusion welding by special welding machines . The pipes
can be bent by heating , but the pipes shall not put to flame . The welding Fusion joint process
involves heating , fusion and cooling .Before welding, the pipe ends may be cleaned with a cloth and
alcohol water solution . after heating the ends on the welding machine for a few second , the
pipe may be removed from the welding machine and the ends may be connected using a little
pressure without twisting . It may be allowed to cool down for a few seconds. The joints may be kept
in a tight condition during cooling.
Water testing shall be adopted for testing PP pipes. The pressure applied shall be 10kg /cm2 . The test
time is to be 2 Hours.
