3. Will affect our health
The purposes : Provide clean water.
To remove contaminants.
Process of contaminated water that had to treated into a
drinkable and usable water.
Vomiting
Diarrhoea

4.  Water is always changing states between
liquid, vapor, and ice.
 Solar energy evaporates water from the ocean,
lakes and rivers. (Evaporation Process)
 Water vapour cools and turns back into tiny
water droplets, forming clouds.(Condensation
Process)
 These droplets fall to earth as rain
(precipitation).
 While the snow melts then it will run to the
river.

7. A procedure to form a “floc”
Purpose: increase the
settling velocity
Alum can neutralize the
negative charges on the
particles in the water.

8. The particles can be clung
together after rapid mixing.
Form ‘flocs’ or ‘flakes’
Mixing is made quite
slowly

9.  Used to reduce the concentration
of particles in suspension
 To decrease the sum of coagulating
chemicals required
 The floc particles to settle to the
bottom and are removed
 Clear water moves off the top

10.  A concrete box which contains sand,
gravel and an underdrain
 Must be backwashed
 The particles rise up and are flushed
 Crystal clear water will be received
by the pipes

11. Protect water against bacteria
Enough chlorine is added
Makes it safe to drink
To protect the public

12.  Water is pumped from the clear
water tank
 Pumping of the clean water
produced at the process of water
treatment to the community is
known as distribution.

14. Deliver water to consumer from water treatment plant to the
house.
Two types of water distribution system
 Point-of-entry system
 Installed on a single tap and treat for drinking and cooking water only.
 Point-of-use system
 Installed on the main water supply line, treat the whole house water.

15.  To remove the chemicals and impurities in water.
 Ion exchange
 To soften the water
 Activated carbon
 Absorb impurities from water
 Reverse osmosis
 Reduces suspended and dissolved matter
 Ultra-violet sterilization
 To kill the microorganisms in the water

16.  Material that suitable used for water piping
Asbestos pipe Ductile cast iron pipe Gray cast iron pipe
Steel pipe Concrete pipe PVC pipe

17. Direct system Indirect system

19. Clean and mineral-rich water
Convenient
Control of water quality
Less risk of being without supply

20. High expenses
Regular cleaning and maintenance needed
Risk of water pollution

22. Physical
 Taste and odor
 Turbidity and Colour
Biological
 Pathogenic Organisms
Chemical
 Hardness
 Iron
 Radon

23.  “Rotten Egg” taste - Hydrogen Sulphide
 Metallic Taste – leach from Copper pipes
 Visual haziness
 Organic compounds derived from the decay of plant and animal matter.
 Water that looks yellowish, brown or red
- Metallic ions such as iron and manganese

24.  Organisms: from ultra-small viruses to relatively large protozoa.
 Disease - typhoid, dysentery, cholera, human maladies(polio,
infectious hepatitis) and some forms of gastroenteritis.

25.  Caused by calcium and magnesium in water.
 Water becomes acidic at low hardness levels
 plumbing corrosion or leaching of lead from soldered plumbing joints
 May leave an insoluble curd on bathtubs, sinks, clothing, and skin.
 Also deposits a scale inside pipes, boilers, and hot water tanks
 reducing their capacity and heat-transfer properties

26.  Easily dissolved in water, particularly
acidic water.
 Can cause corroding metal in pipes,
pumps, and other water-related
fixtures.
 Iron stains leave on sinks, tubs,
showers and other water appliances
 Water smell bad.

27.  Enters through two primary pathways: cracks in
the foundation and release from the water supply
used inside the home
 Formed during the decay of naturally occurring
minerals containing radioactive elements such as
uranium.
 A colourless, odourless and tasteless radioactive
gas.
 May cause risk of lung cancer

29.  Selangor Domestic Water supply
company.
 Supply the water to the building in
Selangor.
 Provide services such as supply clean
water
 Perform periodical
 Maintenance of infrastructure.

30. Supporting process That comprises Finance, Administration, Legal, and Human
Resource, procurement, technology and R&D Management
Process Management That comprises Program and Project & Contract Management
Core Business Process That comprises Supply, Operations & Maintenance, Billing &
Collections, Development Plan Approval and Customer
Service
Quality Management That comprises Training and Client Charter Compliance
Management
Product Information That comprises Distribution Infrastructure Assets

31. Quality Assurance
Programme by Ministry of
Health (MOH)
-Start in 2005
-Water quality becomes more clean and safe to drink
- “National Standard For Drinking Water Quality”
(NSDWQ) issued by the Ministry of Health (MOH).
In-House Water Quality
Assessment
-Start in 2006
-SYABAS has started the in-house Water Quality
Testing Programme
-Collected some samples and sent to third party
for microbiological and chemical analysis.

33. Penang River Klang River

35. River in Malaysia is a major source of our drinking water.
97% of our drinking water comes from river.
1800 rivers with 189 river basins for our consumption, yet we
find ourselves facing water shortages. Why?
Rapid development, growth and industrialization have
resulted in major river pollution issues.

36.  River care program and campaign
 Clean the rubbish
 Upgrade the existing water distribution system
 Water quality restoration
 Improve the exiting sewage treatment plants
 Water conservation & efficiency
 Improve the existed industrial water supply system
 By constructing reservoirs or dams
 To minimize further impacts to rivers and streams
