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

7. WATER SUPPLY PLUMBING SYSTEMS IN BUILDING AND HOUSES
 House Water Connection
 WATER SUPPLY PLUMBING SYSTEMS IN BUILDING AND
HOUSES
Pipe Fittings

8.  Fittings are used in pipe and plumbing systems to connect straight pipe or
tubing sections, 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.
However, any material that is allowed by code may be used, but must be
compatible with the other materials in the system, the fluids being
transported, and the temperatures and pressures inside and outside of the
system. For example, brass- bodied fittings are common in otherwise
copper piping and plumbing systems. The photographs below show some
common fittings that are used in piping systems.

9. FUNCTION OF VALVES
 Control of the water system
 Start or shut down a system
 Regulate pressure
 Check backflow
 Control the direction of water
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. The distinct
feature of a gate valve is the sealing surfaces between the gate and seats
are planar, so gate valves are often used when a straight- line flow of fluid
and minimum restriction is desired

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.
 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

11. 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, or jute is
packed into the open space between the bell and spigot. A strap is placed
around the joint and molten lead is poured in and tampered.
 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.

12.  Flexible Joint: - The direction and the slope of pipes connected by a
flexible joint can be varied up to a maximum of 20o. This joint is especially
suitable for pipes being under water.
 Concrete Pipe Joint: - Concrete pipes 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 not under pressure. h)
 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

13. 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 fitting or 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.
 House/Building Drain: - Part of the lowest horizontal piping of a
plumbing system which receives the discharges from the soil, waste and
other drainage pipes inside of a building and conveys it to the house sewer
outside of the building.
 House/Building Sewer: - extends from the house drain at a point 0.60
meters from the outside face of the foundation wall of a building to the
junction with the street sewer or to any point of discharge, and conveying
the drainage of one building site.

14. Waste Vent
 the ‘backbone’ of the entire sanitary
 System Connected to the Main Soil & Waste Stack
 The portion where waste does not travel through
 Continues to the roof; the portion penetrating the roof is called the Vent
Stack Through Roof (VSTR)

15. 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.

16.  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.
REQUIREMENTS OF TRAPS: -
 Each plumbing fixture, except those with integral traps, shall be separately
trapped with an approved-type water seal trap.
 Only one trap shall be permitted on a trap arm (portion of a fixture drain
between a trap and the vent)
 One trap, centrally located, may serve three single compartment sinks or
laundry tubs or lavatories, adjacent to each other and in the same room,
where their waste out lets are not more than 0.75m apart.

17. CONCLUSION
• We learn about this project how to apply drainage system and water
