Plumbing is defined as the art and science of installing pipes, fixtures, and other components to bring in water and remove liquid waste from buildings. It includes water supply pipes, drainage pipes for waste and sewage, ventilation pipes, and plumbing fixtures like sinks and toilets. Historically, early civilizations like the Indus Valley, Egyptians, and Romans developed basic plumbing and sanitation systems using materials like copper, lead, and ceramic pipes. Modern plumbing systems incorporate various specialized components to efficiently supply water and remove waste from buildings in a sanitary manner.
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

Big Data in the Water Sector - Integrated Water Network Management - IWC's IT...David Kenny
Smart Water Networks are a reality and they are certainly the future but what is slowing their proliferation? The water industry supply chain has embraced technological enhancements in sensors, communications, analytics and control yet water utilities are reluctant to adopt them. Are we about to see the light at the end of the tunnel as Big Data technologies come to the fore or will current attitudes, particularly risk aversion, hold us back?

sanitation and its importance is explained along with drainage system , principles of drainage system , types of pipes , traps and their uses and sanitary fittings.
A building is provided with a drainage system to discharge effectively the sewage of the building into the public sewer. Domestic sewage from a building includes human excreta as well as discharge from the bathroom, kitchen, etc. and collected by building sewers and finally discharged into the public sewer.

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.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
This slide is special for master students (MIBS & MIFB) in UUM. Also useful for readers who are interested in the topic of contemporary Islamic banking.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Basic Plumbing System
1. PLUMBING
• The art and science of creating and
maintaining sanitary conditions in
building used by humans.
• It is also defined as the art and
science of installing, repairing and
servicing the pipes, fixtures and
appurtenances necessary for bringing
in water supply and removing liquid
and water-borne wastes;
2. PLUMBING
• the art and science of installing in
buildings the pipes, fixtures and other
appurtenances for bringing in the
water supply and removing liquid and
waterborne wastes. It includes the
fixtures and fixture traps; the soil and
waste pipes; vent pipes; the building
drain and building sewer; and the
storm drainage pipes; with their
devices, appurtenances and
connections to all within or adjacent to
the building.
3. Historical Background
• Since the dawn of civilization plumbing and sanitation
has been part of human lives. All human beings,
regardless of culture and race had been practicing the
act of disposing waste since time immemorial.
• Historians, in their attempt to trace the history of
plumbing, events which had brought about changes that
led towards the plumbing system that we know today,
had painstakingly devised records of chronological
events.
4. Historical Background
• The first artifact to have been unearthed was a
copper pipe used in a water system in the ancient
palace ruins in the Indus Valley. It was estimated
to be 5,500 years old. Such discovery established
the earliest known knowledge on plumbing
systems.
• Around 2,500 BC, the Egyptians used copper pipes
in their irrigation and sewerage systems. In the
ancient Babylon, the science of hydraulics had
been established as evidenced by their skillful
planning in their network of canals. The
inhabitants of Crete to collect water for drinking,
washing, bathing and cooking purposes,
constructed freshwater cisterns.
5.
6. Historical Background
• During the Roman Empire (500BC - 455AD), enormous concerns on
the field of sanitation and plumbing had been observed those times.
Aqueducts were built to convey water from sources to houses.
Extensive underground sewer systems were constructed. Notable
among these developments is the construction of underground
public water supply system made of cast lead sections.
• Public baths had proliferated; one particular example is the Bath of
Diocletian, a bath that could accommodate 3,200 bathers at one
time. These baths were lines with ceramic tiles. In addition. Roman
bathhouses also include large public latrines, sometimes with marble
seats.
• The quality of plumbing declined after the fall of the Roman Empire
in AD.. 476. During the middle ages, people disposed of waste
materials by throwing them into the streets. !n 1500's, a type of
water closet was developed. Septic tanks were introduced in the
mid-1800's, and a modern sewerage system began operating in
London in the 1860's.
11. Definitions and Basic Plumbing Principles
Plumbing System
• The plumbing system of a building includes the water
supply distributing pipes; the fixture and fixture traps;
the soil, waste and vent pipes; the building drain and
building sewer; the storm water drainage, with their
devices, appurtenances and connections within the
building and outside the building within the property
line.
12. Water Supply System
• A system in plumbing which provides and
distributes water to the different parts of
the building or structure, for purposes
such as drinking, cleaning, washing,
culinary use, etc.; it includes the water
distributing pipes, control devices,
equipment, and other appurtenances.
14. Drainage System
• All the piping within a public or private
premises which conveys sewage,
rainwater or other liquid wastes to a point
of disposal. A drainage system does not
include the mains of public sewer systems
or a private or a public sewage treatment
or disposal plant.
16. Sanitary Drainage and Vent
Piping System
• The sanitary drainage and vent piping
system are installed by the plumber to
remove wastewater and water-borne
wastes from the plumbing fixtures and
appliances, and to provide circulation of
air within the drainage piping.
19. Sanitary Drainage Pipes
• Pipes installed to remove the wastewater
and water-borne wastes from plumbing
fixtures and convey these to the sanitary
sewer and other point of disposal.
20. SANITARY DRAINAGE SYSTEM
• BUILDING/HOUSE SEWER
That part of the drainage system that
extends from the end of the building drain
and conveys its discharge to the public
sewer, private sewer, individual sewage
disposal system, or other appropriate
point of disposal.
21.
22. Privy
– The oldest form of disposal of
organic waste
– It consists of a water tight vault
constructed of concrete for the
collection of raw sewage and a
wooden shelter.
– It must be 50’ to 150’ (15m to
45 m) away from the water supply
– The vault should be supplied
with ventilation
– It should be screened and
protected from vermin and flies.
23. Septic Tank and Seepage Pit
– In this type of sewage disposal, the cycle is completed below ground and
within the property. Liquid wastes are purified due to the action of
anaerobic bacteria through precipitation in the digestion chamber and
effluent is discharged in the leaching chamber by natural percolation.
- Effluent –liquid discharge
- Scum- non-soluble organic matter that floats on the surface of the sewage
- Sludge- organic matter that settles at the base of the septic tank
- Size of tank:
Residence
- 6 persons min capacity of 50 cu ft, and for larger
household 5-6 cu. ft/person
Commercial, industrial and institutional
- 2-3 cu ft/person
- Location must be near the structure served:
(5’) 1.50 m
- water-tight and gas-tight and 50’ –150’
(15m-45m) away from water sources
24.
25. Parts of a Sanitary House Sewer
Drainage – It extends from the public sewer to the private
sewage-disposal tank to the wall of the
System structure and is entirely outside the building

– Sanitary drain throughout the house drain and
– Leader drain stacks discharging above the roof
• Copper – A necessary adjunct to the house
• Plastic trap
• Extra heavy cast-iron
– Slope at 1/8” or ¼” per foot
– A cleanout at the cellar/basement
wall is recommended to clear
obstructions
– A cleanout at the foot of each waste
and soil stack should be installed
27. Soil and Waste Stacks
– The soil and waste stacks collect
the sewage from the fixtures through
their branches.
• Should rest solidly at the bottom on
masonry piers or heavy posts
• The upper ends should extend
through the roof for ventilation
• Made of heavy cast-iron, copper,
plastic
• Supported at intervals of 10’ with
stout wall hangers or brackets or on
beams
• Min 4” Ø 1’ below the roof
• It should be straight free of bends
and turns
28. Fixture Branches
– Connect the fixtures
with the stacks
– Waste or soil
branches are
connected to the trap
of each
fixture
– 1/8” – ½” per foot
– Horizontal branch should not be
more than 5’ (from the vertical inlet of
the trap to the vent opening
– Cast-iron, plastic, copper or
galvanized steel
29. Traps
– Traps catches water after each discharge from a
fixture so as not to allow unpleasant ad obnoxious
gases in a sanitary drainage system to escape
through the fixture
– All fixtures are to be provided with its own trap except for
three laundry and kitchen sinks connected to a single trap
30. – Trap seal must have a min depth
of 2” and max of 4” depth
– Placed within 2’ of the fixture
accessible for cleaning through its
bottom with a plug
– Made of steel, cast-iron, copper,
plastic and brass except those in
urinals and water closets which
are made of vitreous china cast
integrally with the fixture
31. Vents
– Vents are the extension of soil and
waste stacks through the roof and a
system of pipes largely paralleling the
drainage system for the admission of
air and discharging of gases.
32.
33.
34. Interceptors
– device designed and installed so as
to separate and retain deleterious,
hazardous, or undesirable matter
from normal waste and permit normal
sewage or liquid waste to discharge
into the disposal terminal by gravity
35. Sump and Ejectors
– A sump is a tank or a pit which
receives sewage or liquid waste,
located below the normal grade
of the gravity system and must be
emptied by a mechanical means
– Sewage ejectors may be motor-
driven centrifugal pumps or they may
be operated by compressed air.
Ejector pump for submersible system
Ejector for Vertical lift submerge pump
36. Backwater valves/check valve
– A backwater valve closes to prevent reverse
flow from a sewer to low facilities when there
is a heavy drainage load for short periods that
can cause building up and over flow of wastes.
Roof Drain
– Is a receptacle designed to collect
surface or rain water from an open
area and discharge to a catch basin
Floor Drain
– Is any pipe which carries water or
waterborne wastes in a building

• and prevent at least three major difficulties:
– Retardation of flow
– Material deterioration
– Trap seal loss
Retardation of flow.
• The result of improper atmospheric conditions, because of
insufficient ventilation or incorrect installation of fittings.
• Increased pressure causes retarded flow in the vertical stack
and also affects the discharge capacity of its branches
– Material deterioration.
• Wastes create chemical compounds of an acid nature which
deteriorates the piping system. Objectionable gases should be
eliminated by proper ventilation.
– Trap seal loss.
• Attributed to inadequate ventilation of the trap and the
subsequent minus and plus pressure which occur
39. • Five ways in which trap seal is lost:
– Siphonage (direct or indirect)
– Back Pressure
– Capillary Attraction
– Evaporation
– Wind Effect

45. Ventilation System
• A system of pipes, fittings and other
devices installed for the purpose of
providing circulation of air and creating
balanced atmospheric condition within the
system thereby preventing siphonage and
backpressure.
46. Soil Pipe
• A pipe that conveys the discharge of water
closets or similar fixtures containing fecal
matter, with or without the discharge of
other fixtures to the building drain or
building sewer.
47. Waste Pipe
• A pipe that conveys only liquid waste free
of fecal matter.
A waste pipe is generally smaller than a
soil pipe because of the nature of matter
being discharged into the system. A waste
pipe may be connected directly or
indirectly depending on the type of fixture.
