This document discusses water supply and drainage systems for buildings. It covers the components of water distribution systems like service pipes, distribution pipes, and valves. It also discusses sanitary drainage systems, including waste pipes, vent pipes, traps, and stacks. Traps are especially important as they prevent sewer gases from entering buildings by providing a water seal. Proper ventilation of pipes is also essential for drainage systems.

3. INTRODUCTION
WATER DISTRIBUTION SYSTEM
 The water service pipe, water distribution pipes, and the necessary connecting
pipes, fittings, control valves and all appurtenances in adjacent to the structure
premises.

4.  PARTS OF WATER DISTRIBUTION SYSTEM: -
 SERVICE PIPE: - The pipe from the water main or other source of potable water supply to
the water distribution system of the building served.
 WATER METER: - Device used to measure in liters or gallons the amount of water that
passes through the water service.
 DISTRIBUTION PIPE/ SUPPLY PIPE: - A pipe with in the structure or on the premises
which conveys water from the water service pipe or meter to the point of utilization
 RISER: - A water supply pipe that extends one full story or more to convey water to
branches or to a group of fixtures.
 FIXTURE BRANCH: - The water supply pipe between the fixture supply pipe & the water
distributing pipe.
 FIXTURE SUPPLY: - A water supply pipe connecting the fixture with the fixture branch.

5. WATER SUPPLY PLUMBING SYSTEMS IN BUILDING AND HOUSES
 House Water Connection
Example :-

6.  WATER SUPPLY PLUMBING SYSTEMS IN BUILDING AND HOUSES
Example :-

7.  Fittings are used in pipe and plumbing systems, to adapt to different sizes or shapes, to branch or re-direct the
piping system and if necessary, to provide a jointing method if 2 dissimilar piping materials are used in the one
system. Fittings for pipe and tubing are most often made from the same base material as the pipe or tubing being
connected, e.g., stainless steel, steel, copper or plastic

8. FUNCTION OF VALVES
 Control of the water system
 Start or shut down a system
 Regulate pressure
 Check backflow
 Control the direction of water

9. TYPES OF VALVES
 GATE VALVE: - The gate valve, also known as a sluice valve, is a valve that opens by lifting a round
or rectangular gate/wedge out of the path of the fluid.

10.  GLOBE VALVE: -
A globe valve different from ball valve is a type of valve used for regulating flow in a pipeline,
consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.

11.  BALL COCK VALVE: -
A ballcock (also ball-tap or float valve) is a mechanism or machine for filling water tanks, such as those
found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow

12. TYPES OF JOINTS
 Bell (Socket) and Spigot Joint: -
This is used for both cast iron and steel pipes. The spigot end of
the pipe is pushed into the bell end, a tarred gasket made of
cotton yarn.

13.  Threaded Joints: -
There are strong in pipes. A rubber gasket is used to make the joint
water tight. The bell end is threaded on the inside to fit with an outside
threaded ring. This ring presses against the rubber gasket making the
joint water tight.

14.  Flexible Joint: - The direction and the slope of pipes
connected by a flexible joint.
 Concrete Pipe Joint: - Concrete pipes are connect with bell
and spigot joints. Are generally used with a rubber ring to
make the joints water tight. Such joints are used for water
pipes.)
 Asbestos Cement Pipe Joint: - This consist of a steel or
cast-iron sleeve which fits over the ends of the pipes, it is
made water tight with two rubber rings placed between the
sleeve and pipes. Sleeves are frequently constructed of the
same material as the pipe

15. SANITARY DRAINAGE SYSTEM
 Waste Pipe: - conveys only wastewater or liquid waste free of fecal matter.
 Vent Pipe: - used for ensuring the circulation of air in a plumbing system and for
relieving the negative pressure exerted on trap seals.
 Trap: - A device designed and constructed to provide, when properly vented, a liquid seal
which prevents the backflow of foul air or methane gas without materially affecting the
flow of sewage or wastewater through it.
 Stack: - the vertical main of a system of soil, waste or vent piping’s extending through
one or more stories and extended thru the roof.
 Branch: - any part of the piping system other than a main,
riser or stack.

16. WASTE VENT
 the ‘backbone’ of the entire sanitary
 System Connected to the Main Soil & Waste Stack

17. TRAP
In plumbing, a trap is a U-, S-Q-, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is
also known as the S-bend. The bend is used to prevent sewer gases from entering buildings. In refinery applications,
it also prevents hydrocarbons and other dangerous gases from escaping outside through drains. Another shape is X-
shaped trap. The most common of these traps in houses is referred to as a P- trap.
 NAHANI TRAP/FLOOR TRAP: - This trap is provided in
the floor to collect waste water from washbasin, shower,
sink and bathroom etc. These are available in cast iron or
UPVC material and have removable grating (JALI) on the
top of the trap. The minimum depth of water seal should be
50 mm.

18.  GULLY TRAP: - These traps are constructed outside the
building to carry waste water discharge from washbasin,
sinks, bathroom etc. and are connected to the nearest
building drain/sewer so that foul gases from sewer do not
come to the house. These are deep seal traps; the depth of
water seal should be 50 mm minimum. It also prevents the
entry of cockroach and other insects from sewer line to
waste pipes carrying waste water.

19. REQUIREMENTS OF TRAPS: -
 It should be made of non-absorbent material.
 It should provide sufficient depth of water seal all times (about 50 mm)
having large surface area.
 It should be self-cleaning and should not obstruct the flow of sewage.

20. CONCLUSION
 We learn about this project how to apply
drainage system and water supply system.
