level above the invert level of pipe, but below the top of the barrel, the pipe
sewers shall be haunched.

Encasing
The sewer pipes shall be completely enc ased or surrounded with concrete.
a)

Where the maximum Water table level is likely to rise
above the top of the barrel.

b)

Where the sewers are to be laid adjacent to growing trees, to
avoid damage or displacement to pipe joints or to the pipe
likely to be caused by the roots of the trees.

c)

removed with a flat chisel and the joint caulked round three times with
caulking tools of increasing thickness and hammer 2 to 2.5 Kg. weight.
Lead joints shall not be covered till the pipe lines are tested under
pressure, but the rest of the pipe lines many be covered to prevent
expansion and contraction due to variation in temperature.

9.6.5

Lead wool joint Wherever it is impracticable or dangerous to use cast molten lead, such as
inverted joints or in wet drainages or under water where there is a need
for cold application, joints may be made with caulking lead wool or lead
yarn. Joints caulked with lead wool or lead yarn shall withstand greater
displacement than cast lead joints.

Jointing shall be made of with caulking lead wool or yarn inserted in
strings of not less than 5mm. thick and the caulking shall be repeated with
each turn of lead wool or yarn. The whole of the lead wool or yarn shall
be compressed into a dense mass. When working with lead wool, it is very

space to thoroughly consolidate the materials from the back to the front of
the socket.

flange with proper pipe hole and bolt hole neat and even at both the
inner and outer edges. Where the flange is not fully faced, the packing
may be of the dimension of the facing strip only. Its proper placing should
be tested before another pipe is joined on.

9.8

The led joints shall be tested to a pressure of 150 1bs/sq. inch minimum
[10.54 kg./sq.cm] or such head as otherwise specified after being caulked
and should any leakage o ccur, the leaking joints shall be remade and

established.

9.9

Water Pressure Mains Shall conform to IS 1538 - 1967 Class LA as specified in the schedule.
They shall be laid, jointed, and tested along with Cast Iron pipes as
described in the specification for Cast Iron S/S pipes.
After each section of the pipe line has been completed it shall be tested for water
tightness before being covered. This can be done by closing each end, by means of
a valve or blank flange, or plug and fill the pipe with water. The pressure should then
be raised by means of a small hand operated pump till it registers fifty percent
more than the 150 p. s. i. [10.54kg./Sq. cm] and the test pressure should be
ascertained by means of a reliable gauge. When the pipe is laid on any appreciable
gradient, the test should be carried out at the lower end of the section
with an air
vent at outer end. Any leaking joint should be made good and the above test
reapplied until no further leaks are apparent.
