INTRODUCTION
• House Drainage System The W.C, Bathrooms, Sinks,
Wash basins, etc. are important components of a house.
The occupants of the house make use of the above
components and as a result of that there is a formation of
waste water. The Waste water from W.C, bathrooms,
sinks and wash basins is to be properly disposed in to the
municipal sewers. It is therefore necessary to construct a
system of conveyance of wastewater from W.C,
bathrooms, kitchens and washbasins and disposal to the
municipal sewer. This system is known as house drainage
system.
BASIC DRAINAGE COMPONENT
SINKS- Kitchen sinks and laboratory sinks are connected
to waste pipes and or waste appliances. Slop sink used in
hospitals is a soil appliance .
• Vitreous sinks have been restricted.to laboratory use only as they are
not found suitable for kitchen use. The sinks suitable for laboratory
use shall be in the sizes 400 X 250 X 150 mm, 450 X 300 X 150
mm, 500 X 350 X 150 mm. 600 X 400 X 200 mm and 600 X 450 X

MATERIAL USED IN DRAINAGE
SYSTEM
• We have different types of piping for different uses,including fresh
water supply,waste drainage,irrigation,gas pipes for applications, and
so on.which type is used in which application will largely depend on
the age of your plumbing system.
• Some plastic pipe used in plumbing (such as PVC and CPVC)
may also be used in the venting of high efficiency condensing
furnaces.
MATERIAL STORE ROOM
• Cast iron for plumbing waste lines.
• PVC (Poly-Vinyl Chloride) for plumbing waste lines.
• Chromed brass for plumbing waste lines
• Chromed copper for water supply lines.
• Galvanized iron for water supply lines.
• Copper (rigid and flexible) for water supply lines.
• CPVC (Chlorinated Poly-Vinyl Chloride) for water supply lines.
• PEX (Cross-linked Polyethylene) for water supply lines
• Black Iron for gas pipes.
Cast Iron for Plumbing Waste Lines:
• Appearance: Large-diameter heavy metal pipe, dull black with a
rough, mottled surface.
• Description: High-quality sanitary waste drain pipe that is heavy and
deadens the sound of flowing waste water very well. This pipe is
strong and long-lasting but hard to cut—often requiring a special
cutting tool with sharp chain cutting wheels. Repairs are often made
using plastic PVC piping.
• Prevalent Use: Use for main soil stack waste lines and vent pipes.
• Cutting and Fitting: Requires heavy-duty reciprocating saw or
special cutting tool , called a cast-Iron pipe cutter. Fitting cast-iron
pipes and fittings together is done using special methods,
including lead and oakum in soil pipe joints
PVC (Poly Vinyl Chloride): for Plumbing
Waste Lines:
• Appearance: White rigid plastic.
• Description: PVC is now the de-facto
standard in home waste line materials.
It is a strong, chemical-resistant rigid
pipe that is heat resistant .
• Prevalent Use: Use for sanitary waste
lines, vent pipes, and drain traps.
• Cutting and Fitting: PVC pipe is easily
cut with a hacksaw or tubing cutter. The
sections are joined together
mechanically, using special chemical
solvent
Chromed Brass: for Plumbing Waste
Lines:
• Appearance: Bright, shiny chrome-finished pipe of larger diameter
(+1”)
• Description: Chromed brass is often used in lieu of PVC for exposed
waste line applications, such as “P” traps or other drain traps where
appearance is important.
• Prevalent Use: Exposed drains and traps.
• Cutting and Fitting: Easily cut with a hacksaw, and joined with slip
fittings
Chromed Copper for Water Supply Lines:
• Appearance: Bright, shiny chrome finished pipe of smaller diameter
(3/8” or less)
• Description: Chromed copper pipe is often used where the
appearance of exposed water supply lines is important.
• Prevalent Use: Exposed water supply lines, such as supply tubing for
toilets or pedestal sinks.
• Cutting and Fitting: Easily cut with a tubing cutter or hacksaw, and
joined with chromed brass compression fittings
Galvanized Iron: for Water Supply Lines
and Waste Lines:
• Appearance: Dull silver-gray rigid metal pipe.
• Description: Galvanized iron pipe was once a popular method of
plumbing water supply lines in the home, but it gradually fails due to
corrosion and rust. Forthis reason, Galvanized iron pipe is difficult to
cut and join and not easily fabricated on site by the home owner.
Repairs are usually done by replacing the pipes with copper or PEX.
• Prevalent Use: Water supply lines and drain lines in older homes.
• Cutting and Fitting: Can be cut using a reciprocating saw or
hacksaw. Pipe is joined using using threaded galvanized iron fittings.
Copper (Rigid and Flexible): for Water
Supply Lines and Gas Pipes
• Appearance: Dull, copper-colored metal pipe.
• Description: Copper pipe comes in two types, rigid and flexible. The
rigid type comes in several wall thicknesses. Copper is a soft metal
and so can be easily cut and fabricated.
• Rising costs for copper in recent years have caused PEX and CPVC
to be used more frequently. Copper pipe costs as much as three
times as much as PEX.
• Prevalent Use: Rigid copper pipes are used for longer runs of water
supply, Flexible copper is used in short runs, for water supply, and for
the water supply tubing for refrigerators and dishwashers. Copper
may also be used for gas piping.
• Cutting and Fitting: Copper pipe is easily cut with a tubing cutter or
hacksaw. Sections are joined together with soldered copper
compression fittings. Flexible copper pipe may also be terminated by
flaring its end and using brass flare fittings.
CPVC (Chlorinated Poly Vinyl Chloride):
for Water Supply Lines:
• Appearance: Dull white or
cream-colored plastic.
• Description: CPVC is an
inexpensive rigid plastic that
is designed to withstand high
pressure and temperature.
• Prevalent Use: CPVC is
used for hot and cold water
supply piping.
• Cutting and Fitting: The
pipe is easily cut with
a tubing cutter or hacksaw.
CPVC is joined permanently
together using plastic fittings
and solvent glue,
Black Iron: for Gas Pipes:
• Appearance: Dull black rigid pipe, usually 1" or less in diameter.
• Description: Black pipe looks like almost exactly like galvanized iron
pipe, except it is darker and specifically designed for gas applications.
• Prevalent Use: Natural gas or propane supply pipes. It is often used
for feeding gas supply to the furnace, boiler, or water heater.
• Cutting and Fitting: Can be cut using a reciprocating saw or
hacksaw. Pipe is joined using threaded black pipe fittings.
Black iron pipe
REQUIREMENT OF DRAINAGE
SYSTEM
• Drainage systems is a piping system which disposes household
effluents. It consists of two features which work together: the outdoor
and domestic pipelines.
• Main requirements for domestic drainage systems
Domestic drainage system consists of the following elements:
• Plumbing fixture, work of which produces effluents (exception –
heated towel rail);
• Pipes which dispose effluents from plumbing fixture to drainage
system;
• Main sewer.
As for outdoor drainage system, specific requirements are developed,
and they must be followed when installation of drainage system. All
pipeline equipment for domestic drainage system should have high
capacity - . Also it should withstand test pressure which exceeds the
working pressure by 1.5 times, but not less than 0.68 MPa or about 7
bar, and but not less than about 0.45 MPa or 4.5 bar. Also the pipes
should be:
• Durable;
• Resistant to low and high temperatures;
• Smooth inside – smooth inner surface allows to avoid frequent
clogging;
• Mechanically and chemically wear resistant;
• Robust;
• Compatible with outdoor drainage system.
Additionally, you should choose such pipes that are easy to install.
• Basic requirements to
storm-water drainage
system
• Storm-water drainage system is
installed for diversion rainwater and
melt water from roofs of residential
and public buildings. Effluents are
transported through storm-water
drainage system to major storm-
water drain.
• Storm-water drainage system can be
both above-ground and underground,
and pipeline equipment for this
drainage system should meet the
following requirements:
• They should be resistant to UV - if
pipeline is installed above ground, it
is exposed to sunlight every day, so
that equipment which is sensitive to
UV light reduces durability of the
pipeline;
• They should be strong - the storm-
water drainage system should be
high resistant to mechanical stress,
because this system is built for
several decades;
• They should be resistant to aggressive reagents - the the storm-water
drainage system disposes not just rainwater, but also melt water in
which can be a lot of aggressive reagents, because in the winter time
the road is covered with chemicals
They should be resistant to temperature extremes.
• When installing the storm-water drainage system you should consider
the following:
• On the flat roofs of public and residential buildings you can install only
one roof drain on section;
• Roof drains should be located at distance no more than 48 m from
each other;
• Operation rules of drainage systems
• All drainage systems should be operated following the basic rules:
• Cleaning and maintenance of the pipeline should be carried out
regularly;
• All of the pipeline elements must be sealed completely for reducing
likelihood of leakage;
• Diameters of the pipeline equipment must be such that the
wastewater will be disposed without interruption;
• You should monitor the concentration of toxic substances contained in
the effluents, because high concentration of toxic substances can
damage the treatment facilities
• If you will observe this rules, the pipeline will serve a long time with
minimum of failures.
SPECIFICATION OF INDIAN DRAINAGE
AS PER INDIAN STANDARD
GENERALS-
• Each family dwelling unit on premises abutting a public sewer or
with a private waste disposal system shall have at least one
water closet and one kitchen sink or washing facilities. It is
recommended to have at least one bathroom with a bath tub or
