Background: Sime Darby Bhd is currently undertaking a groundwater project in Bacang Padang in Parak to meet the future water needs of Malaysia. One of the groundwater technologies that have been successfully applied is called Radial Collector Well System, which has been widely used in South Korea for its public water consumption and river conservation efforts.
Study Tour Objective: Persatuan Pengguna Islam Malaysia(PPIM) along with members of the Government and media were invited to examine radial collector wells in addition to other well systems used in South Korea.
Sime Darby Bhd also made arrangement for delegates to learn about:
• The public water supply in Jeju island
• The use of rain water for residential homes and
• A successful stream restoration and conservation project in Seoul
Observation: South Korea with its limited annual rain has is utilizing an existing method (radial collector well systems) to provide the people of Korea with water for consumption and public works.
In addition to supplying the populace of Seoul with portable ground water, the government has also restored the Cheon Gye Cheon stream from water supplied from the Han River. Jeju Island has successfully solved its water shortage as well as addressing saline intrusion.
Bottled mineral water is another product which has developed from the radial collector system that they use.
To provide the delegation with other conservation uses of water, Sime Darby Bhd arranged for the delegation to learn about the Rainwater Management System in Star City and an additional radial collector well facility located in Pusan.
I should point out that the Star City water system shows how residential and office buildings can be designed to ecologically conserve and use water while reducing the consumer’s water bill.
Recommendation for Malaysia: While Malaysia has ample rainfall, there are incidences when areas must without sufficient water which leads to rationing this precious resource (water) to meet the needs of citizens.
In addressing issues of water shortages we must do the following:
• Better water management. Malaysia has sufficient rainfall which is inefficiently utilized.
Peninsular Malaysia generally exceeds 1,600 mm, and is well over 2,500 mm in many areas (Dale 1959)
The mean annual rainfall in Sarawak is between 2,500 and 5,000 mm, and is fairly well distributed with no month below 100 mm (Andriesse l968).
• Safeguards to prevent water pollution: Examples.
1. Ecologically friendly methods by sewage treatment plants. 2. Manufacturing industries given the carrot or the stick as incentives to find ways to reduce their contribution to water pollution. 3. Entrepreneurs can be encouraged to develop other uses for waste from animal farms and agro-based industries.
• Educating citizens on sustainable water usage: Early and continued education is one of the best means to drill in the habit of sustainable resource usage.
However, while these measures are being researched; radial collector wells as well as the innovative use of rain water appear to be useful means by which underground water can be economically used to supply states or local principalities during water shortages.
Finally, the natural competition which will grow out of having Sime Darby enter the market, would serve to increase overall water services and decrease water prices for the people of Malaysia.
