A Vision To Clear Solutions.
Introduction
(a) The pipes, fixtures and other apparatus inside a building for
bringing in the water supply and removing the liquid and water borne wastes
(b) The installation of the foregoing pipes, fixtures and other
apparatus.
Pipe – pipes shall have adequate strength to meet the loading
requirements
Plumbing System
The plumbing system shall include the water supply and distribution
pipes; plumbing fittings and traps; soil, waste, vent pipes and anti- siphonage
pipes; building drains and building sewers including their respective
connections, devices and appurtenances within the property lines of the
premises, and water-treating or water-using equipment.

Drinking water supply
a.
Residential- number of fitment is
less
b.
Commercial – number of fitment is
more
c.
Industrial – number of fitment is
more
(Like water cooler, machine drains and washes room)

Points to be consider before laying
·
Material inspection and test result
as per IS codes
·
Excavations –(supports or shoring to
be provided in deep excavation, steel sheet piles to be use in slips and falls)
·
Backfill-(the material satisfy stone
size 150mm/liquid limit is less than 30%/plasticity index no more than
10)/bedding/ geo textile membrane to be provided around the stone filling area
·
Dewatering
·
Free from water, storm, oil, etc.,
·
No blasting
·
Pipe tolerance (the angle deviation
of bends shall be within +-1 degree of the designated for pipes including 600mm
dia and + – 0.5 mm for large dia pipe. Fitting shall be within + -10mm of the
designated length or the manufacturer catalogue values)
·
No crack shall be present in the
inside of the pipe
·
Scratches shall be no more than 0.3mm
·
Impact and external pressure
resistance
·
Longitudinal tensilestrength to be
made accordance with IS code
·
No impact and other end damages
·
Overall thickness, pvc packing
thickness, tensile strength, elongation, tear resistance, adhesion to
steel, adhesion to self, impact resistance, dielectric strength and insulation
resistance should satisfy the IS code requirements.,
·
Defective parts can be replaced
without difficulty
·
Check the suitability of the pipe
·
Follow the recommendations of
manufacturers when joining pipes of different materials
·
If lab- pipe suitable for conveying
all solutions
·
No leakage of contaminated water
·
Materials, joints, supports and
fixing shall be durable
·
Sealant provide all joints carefully
·
Work /all appliances/ materials &
workmanship should be carefully examined for defects and faults in
installation.
·
Good inspection and testing
·
Setting out and alignment
·
Joints- push fit
/mechanical/flanged/grp/anchorage
·
Provide proper support/thrust blocks
·
No bents
·
No airs at bended corners

Drinking water supply
In general, a daily per capita water consumption of at least 200 liters
may be used for most of the e large town and cities in India as design figure
to meet domestic and flushing needs, However, for lower income group ( LIG )
and economically weaker section of the society the value of water supply may he
reduced to135 liters per capita per day.

·
Partially separate methods
System
·
Two pipe system – ground water and
waste water separated and mostly accepted system
·
One pipe system- one main pipe
collects both waste and ground water with
ventilation
·
Single stack system-same as one pipe
but no ventilation
·
Single stack partially ventilated
Sewer connection
Drainage ventilation
Drain pipe laying
Means of access
Bedding of drains
Drains under or near buildings
Pipe cleaning and inspection
Gas supply
