This document discusses plumbing services for a building, including water supply and distribution systems. It covers the cold water system, direct and indirect supply systems, and hot water supply methods. The direct system supplies water directly from mains to fixtures, while the indirect system uses a storage cistern. Centralized hot water systems store and circulate hot water, while localized systems heat water at the point of use. Solar water heaters also utilize energy from the sun.

As well as the comforts and luxuries of modern living Plumbing systems protect the community from disease.
Invisible organisms that swim around in a watery environment was beyond imagination until a few centuries ago, it was only in the late 19th century that scientists discovered and isolated specific microbes of particular a disease, cholera, has proven one of history’s most virulent killers.
Mankind began to understand that the evil spirits causing its woes were microscopic creatures that could be defeated by plumbers and sanitary engineers. With well designed plumbing and draining systems.
As we go about our everyday lives it is comforting to know that people’s lives are protected by having Correctly Installed and maintained Plumbing Gasfitting and Draining Systems.
The arrangemnet provided in a house or building, for collecting and conveying waste
water through drain pipes, by gravity, to join either a public sewer or a domestic
septic tank, is termed as house drainage or building drainage.
WATER SUPPLY AND DRAINAGE SERVICE FOR BUILDINGKaran Patel
The product, delivered to the point of consumption, is called potable water if it meets the water quality standards required for human consumption.
The water in the supply network is maintained at positive pressure to ensure that water reaches all parts of the network, that a sufficient flow is available at every take-off point and to ensure that untreated water in the ground cannot enter the network. The water is typically pressurised by pumps that pump water into storage tanks constructed at the highest local point in the network. One network may have several such service reservoirs.
In small domestic systems, the water may be pressurised by a pressure vessel or even by an underground cistern (the latter however does need additional pressurizing). This eliminates the need of a water-tower or any other heightened water reserve to supply the water pressure.
These systems are usually owned and maintained by local governments, such as cities, or other public entities, but are occasionally operated by a commercial enterprise (see water privatization). Water supply networks are part of the master planning of communities, counties, and municipalities. Their planning and design requires the expertise of city planners and civil engineers, who must consider many factors, such as location, current demand, future growth, leakage, pressure, pipe size, pressure loss, fire fighting flows, etc

Solar water heating (SWH) is the conversion of sunlight into renewable energy for water heating using a solar thermal collector. Solar water heating systems comprise various technologies that are used worldwide increasingly.
In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. WATER SUPPLY -
DISTRIBUTION
DISTRIBUTION
DOMESTIC LEVEL
Carries water from water mains to the various points (fixtures) in the building where water is
to be used.
Cold water system
Hot water system
4. WATER SUPPLY -
DISTRIBUTION
DIRECT SUPPLY SYSTEM (upward distribution system)
When pressure of water supply from the mains is sufficient the supply of
water is directly given to the various floors.
This system is recommended only if no. of floors is not more than two
5. HOT WATER SUPPLY
Hot water is needed in building for comfort during or in low temperature region. The supply is usually
separate from the cold water supply even though it source its cold water from the cold water supply lines.
Usually a medium of heating the water is introduced to heat the water collected from the cold water supply
lines. The heating is usually done in a special reservoir that stores and reserve the hot water for
sometimes.
The need to preserve the heat gained by the water for a reasonable time requires the use of special tanks.
The tanks are usually lagged and sealed to disallow escape of heat from the heated water.
7. WATER SUPPLY -
DISTRIBUTION
DIRECT SUPPLY SYSTEM (upward distribution system)
Advantages
Less pipework and smaller or no cistern, making it easier and cheaper to install.
Drinking water is available at all draw-off points.
Smaller cisterns which may be sited below the ceiling.
In systems without cistern there is no risk of polluting the water from this source.
8. WATER SUPPLY -
DISTRIBUTION
INDIRECT SUPPLY SYSTEM (Down take distribution system)
It is a system whereby all the drinking water used in the building is
supplied from the main and water used for all other purposes is supplied
indirectly from a cold water storage cistern.
The cistern also supplies water to the hot water cylinder therefore its
capacity will almost double the capacity required for the direct system.
10. WATER SUPPLY -
DISTRIBUTION
INDIRECT SUPPLY SYSTEM
Advantages
Large capacity cistern provides a reserve of water during interruption of supply.
Water pressure on the taps supplied from the cistern is reduced, which minimizes wear
on taps and noise.
Fittings supplied with water from the cistern are prevented from causing pollution of the
drinking water by back siphon age.
Lower demand on the water main.
11. HOT WATER SUPPLY

The need to preserve the heat gained by the water for a reasonable time requires the use of
special tanks. The tanks are usually lagged and sealed to disallow escape of heat from the
heated water.
13. HOT WATER SUPPLY
METHODS
1. Centralized System
A centralized is one in which water is heated and stored centrally within the building,
supplying a system of pipework to the various draw-off points.
two systems
Direct DWH system
Indirect DWH system
14. HOT WATER SUPPLY
a) Direct hot water
supply system
Like cold water supply, hot water is
supplied either directly or indirectly.
In the direct hot water supply a unit
of water heater is connected to the
point of use – shower or kitchen sink.
15. HOT WATER SUPPLY
b) Indirect hot water supply
system
In the indirect water supply, a general
heating point/tank is used to supply hot
water to several point or part of a building.
This is usually more applied in hotels and
such other common service buildings.
18. HOT WATER SUPPLY
METHODS
2) Localized System
A localized system is one in which the water is heated locally to it’s use.
Heater can serve only one sink or two if fitted in close proximity with heater.
Two types of localized DWH heaters are found –
Instantaneous
Storage
19. HOT WATER SUPPLY
a) Instantaneous type
They are generally fueled by gas or electricity.
Heat water only when required
They are usually located about the fixture
Flow is inlet controlled.
b) Storage type single points
These are heaters located near sinks and have capacity not more than 15 ltr.
Stored water is heated by an electric element until water is not expanded enough to
discharge from spout.
Cool water from bottom of the unit then replaces the discharged water.
Suitable for small quantity of draw off.
22. HOT WATER SUPPLY
Centralized Vs Localized
Advantages
Provides large bulk of storage
Requires less maintenance
Easier to integrate renewable
technologies
Disadvantages
Long lengths of secondary pipework
which can lead to heat loss
Advantages
May be fitted close to the fittings
Saving in boiler house space and
possible fuel store
No need for secondary circulation or
no problem of long dead legs.
Disadvantages
Separate electricity connections
required for each unit.
24. HOT WATER SUPPLY
Solar water heater
Solar hot water system is a DWH system which utilizes energy from the sun. it collect the
radiant heat waves in a solar collector, usually located on the roof of the building.
Cold water is supplied to a warm water store vessel which is heated by solar energy
Water then passes onto a normal conventional hot storage cylinder and is supplied with
additional heat (if required) by a electric boiler.
Hot water have lower specific weight so it remains on top.
