on hand cart or manually lifted for transportation.
Certain breakages results during the course of laying and hydraulic testing. These breakages shall be to
the account of contractor and no payment on this quantity is admissible for the item of providing of
pipes and as well as for the item of lowering, laying of pipes. The final quantity payable under this
item shall be restricted to the total length laid and successfully tested for that diameter and class of
pipes.
Hydraulic Test
Suitable section as directed by the Engineer-in-charge shall be taken for such testing
from time to time during progress of the work and satisfactory test given for that section. All testing
apparatus, gauges, connections, etc. and water required for testing shall be arranged by the
Contractor at his cost. The VWSSC does not undertakes any responsibility to supply water for
testing, which the Contractor has to arrange from the municipality or otherwise by paying the
required charges directly. The VWSSC shall have the right to recover such charges from his bills if
complaints are received that Contractor has not paid the charges thereof. If there is delay in testing,
the Contractor shall refill the trenches for the time being and reopen them at time of testing at his
own cost, failure of which shall entitle the VWSSC to do the refilling and reopening of trenches at the
risk and cost of the Contractor. If the trenches are filled due to any reason whatsoever before testing,
the Contractor shall have to open them for testing at no extra cost.
1. Satisfactory hydraulic test shall be regarded when the section under test shall withstand the
pressure as specified by the Engineer-in-charge for about 15 minutes without operating the test
pump, the test pressure being maintained at the specified figures during that 15 minutes interval.
2. The field test pressure shall be as per circular no. MJP/RCC/322, dated 31-12-1997. After laying
& jointing any pipeline, the pipe line must be hydraulically tested to ensure that pipes & joints are
strong enough to withstand the maximum pressure likely to be developed under working
conditions. All pipe lines should be tested as per the following field test pressures. Field test
pressure for MS/DI/PSC/PVC/CI/ concrete pipes. as para 6.4.4.2 of G.O.I. manual on water
supply & treatment should not be less than the maximum of the following.
a) 1½ times the maximum sustained operating pressure.
b) 1½ times the maximum static pressure in the pipe line.
c) Sum of maximum sustained operating pressure & the maximum surge pressure.
d) Sum of maximum pipe line static pressure, subject to maximum surge pressure, subject
to maximum equal to work test pressure for any pipe / fitting incorporated.
The field test pressure should wherever possible be not less than 2/3 work test pressure
appropriate to the class of pipe except in case of spun iron pipes & should be applied & maintained for at
least four hours. If the visual inspection satisfies that there is no leakage the test can be passed.
Where the field test pressure is less than 2/3 the work test pressure, the period of test should be
2
increased to at least 24 hours. The test pressure shall be gradually raised at the rate of 1 Kg/cm /min. If
the pressure measurements are not made of the lowest point of section an allowance should be made for
the differences in static head between the lowest point & the point of measurement to ensure that the
maximum pressure is not exceeded at the lowest point. If the drop in pressure occurs; the quantity of
water added in order to re-establish the test pressure should be carefully measured. For P.V.C. pipes this
should not exceed 1.5 lit. Per 10 mm of nominal bore for a length of 1 km.
During testing if any joints are found leaky they shall be repaired and/or redone by the Contractor at
his cost till the test is found satisfactory. Similarly, any pipes, collars, specials, show hair cracks,
leaks, etc. during testing the Contractor shall replace them with sound pipes and specials together
with new joints, entirely at his own cost, till a satisfactory test is given. The pipe, specials, etc. which
crack during testing will, however, be supplied by the Contractor, replacement free of cost. The
hydraulic test shall be given in the presence of the Engineer-in-charge.
20% amount of the item of laying, Jointing of pipe line will be withheld for hydraulic testing.

Hydraulic Test- Procedure as per given above.
J) PCC 1:2:4
Materials required for Construction
1. Sand, Metal
Sand, metal and bricks of best variety within a lead of 30 kms will be insisted. Samples of these will
have to be got approved prior to use on work.
2. Cement
OPC of L & T brand of 43 grade in Jute / Polyethylene bags(weighing 50 kg. each)shall be used for
all water retaining structures.
3. Concrete
The PCC and RCC works shall be as per IS 456/1976.
Concrete mixer shall be used for preparing concrete.
Vibrator shall be used to consolidate concrete while placing in position.
K) Refilling the trenches with available excavated stuff
When tender item provides that murum available from excavation is to be used free of cost, what
ever murum that is available The murum filling is to be done in 15 cm to 20 cm thick layers, watered
and duly consolidated by hand rammers as directed.
In no case the Contractor shall be allowed to refill the trenches in hard excavated portion to be
refilled by the boulders or the excavated stuff. This portion of trench shall be refilled by the soft
murum or soft strata from excavated stuff from distant place. No extra cost shall be paid.
After the pipelines are laid, jointed and tested, the refilling of trenches with excavated stuff shall be
done approximately in 20 to 30 cms. higher than road or natural ground level, to allow for sinking
afterwards. This refilling shall be done in15 cms. thick layers, duly watering compacting, each layer.
The 15 cms thick layer immediately in contact on or under pipe shall have no stones or chips, but
only soil or soft murum selected from the excavated stuff after refilling. If it is sunk below the road
level after some time till completion of work, the Contractor shall have to make it good at his cost.
Before lowering of all pipes in trenches a layer of murum selected from excavated stuff shall be
provided below pipeline for proper grading and to act as cushion, etc. No payment against refilling
trenches shall be allowed until satisfactory hydraulic testing given.
A) Trial Run -
On completion of scheme, the Contractor should commission the scheme to its rated capacity,
including cost of all labour items, attending execution defects noticed, including cost of material and
labour for above period till the time the concerned Village Panchayat takes over the scheme
