We are all well aware that clean water is crucial to our health and even though our city water supply has been treated by the municipality to meet the standards of the World Health Organization (WHO), water contamination can still occur in many instances. The sources for bad quality of water supply are listed and summarised as follows:
i) Watershed Area Pollution
Widespread industrial activities and the development of society itself has increased the risks of water source contamination. Pollution from runoff, wastewater discharge from industrial areas, sewage from residential areas, agricultural activities, and leachate from dumpsites can, directly or indirectly, pollute our water source.
ii) Ageing and rusty pipes
Our city water is treated at the treatment plant, whereby chlorine and alum are added to clean and sterilize the water to produce drinkable water. However, water contamination may occur as it travels along old and rusty distribution pipelines to consumers. Rust and metals might leach into the water through rusty pipes or rusty joints.
iii) Old and Damaged Pipes
Unfortunately, our pipes have been in use for more than 60 years, having been installed in the 1960’s resulting in many instances of damaged and leaky pipes. Pollutants such as mud and sediment, organic and inorganic chemicals, heavy metals, and other toxic substances may then enter our water supply via these damaged pipes.
iv) Stagnant Water Storage Tank and Plastic Pipeline
Stagnant water will encourage bacteria and pathogens to grow in the water storage tank and fungi and algae might also grow in the plastic pipes (PVC). These are harmful to health and need to be removed before consumption.
WATER QUALITY PROBLEMS
Many cities in Malaysia have been affected by the water quality problems as discussed above. Based on our professional experience, the common water problems affecting the public are as below:
The Aesthetics Quality of Water
Turbidity in the water supply is contributed by mud, sediment, and
The appearance of a yellowish or brownish colour in the water supply
may be due to the high turbidity and/or contributed by iron and rust
from rusty pipes.
iii)Taste and Odour
Unpleasant or repulsive smells may be contributed by chlorine, sulphur
(rotten egg smell), and organic pollutants.
Water with high turbidity and colour can stain our laundry, sinks, and toilet bowls and leave the bathroom with unsightly slime.
Health Related Concerns
Chlorination is one of the processes of treating our city water for
sterilization purposes. Residual chlorine of 0.2 ppm is to be maintained in
our water supply to kill bacteria and pathogens in the distribution
pipeline. Chlorinated compounds are carcinogens, meaning they are
cancer-causing agents and is very harmful to human health if it is
consumed continuously at an excessive level. In addition, chlorine as an
oxidizing agent and can slowly corrode most of the galvanised iron
pipelines and water tanks.
Water supply may be contaminated by bacteria and pathogens as a
result of industrial waste discharge, sewage seepage, and/or dumpsite
leachate that enters the water supply via damaged pipes.
iii)Organic and Inorganic Chemicals and Heavy Metals
Organic and inorganic chemicals may be found due to farming activities
such as using chemical fertilizers and pesticides; and the wastewater
discharge from industrial sector. The inorganic chemicals like alum,
sodium fluoride and heavy metals (mercury, lead, arsenic, zinc, etc) are
harmful to the body.
