Based on the article which refer to Klang Valley water pollution. we believe that, the
management of development and urbanization is actually very important.
It is important in water management to ensure for health to human and environment. There are
two categories for water pollution sources as listed as below:
1. Point sources
2. Non-point sources
Point source is refer to sources that can define the starting point such as from sewage treatment
plant (STP), effluent from factory, from toilet and etc.
Non-point sources is refer to pollution which release to water without knowing the sharp point
such as surface water runoff, rainwater and etc.
Pollution of water is actually define that the incoming water is contain with excess chemical
constituent such as pesticides, ammonia, spilled carbon petroleum, detergent, fertilizers, organic
matter and etc. Rain which carry sulfur dioxide or nitrogen dioxide also may cause water
pollution.
Instead of chemical release, water pollution also may generated from discharge of heated water
especially industrial process or power stations.
The contamination may harmful to aquatic life and furthermore will destroy the aquifier. Many
of the chemical substances are toxic or even carcinogenic.
Many of the municipal water supplies in developed countries can present health risks. That is
why, proper management of water may save a lot of thing.
There is no other way for water manager at water treatment plant if the water sources has been
polluted except to shut down the plant. They have to ensure the action to be taken to makesure,
there is no unwanted incident will happen to community health.
Every organazation which related to water management must realise that, every discharge to
upstream river must be well treated. They have to follow standard quality effluent which is
earlier regulated by DOE.
Although, there is a regulation behind that, some of incident such as bund broke (refer to landill
leachate release from Semenyih landfill) were likely define as unexpected incident. As the
consequences, there must be a plan to response to this kind of pollution. Idea must be raised
such as to relocated the landfill to downstream area, and it must be planned earlier.
