Integrated Water Resources Management Improving Langat Basin Ecosystem Health

The ecosystem provides us with all the goods and services that form the base of our economic, social cultural and spiritual life. Good scientific information will be required for managing the environment by using the Ecosystem approach. The groundwater is considered as a possible supplementary of alternative water source, and some factories already started shifting their water source from surface water to groundwater. Uncontrolled use of groundwater, however, may induce serious environmental problems, e.g., land subsidence, saltwater intrusion to the aquifer. The establishment of a balanced multi-sector and integrated groundwater resources and environmental management plan is deemed urgent to attain a sustainable groundwater resources use and to maintain a favorable groundwater quality in the Langat Basin. To achieve sustainable lifestyle in large scale ecosystem requires integrated and holistic approaches from all stakeholders. Through Aquifer Storage Recovery (ASR) it was determined a revolutionized water resources management, providing a sustainable supply while minimizing the environmental impact of surface storage. By using underground geologic formations to store water, by integrated water resources management advisory system (IWRMAS) aquifer recharge can now easily applied to obviate water resource and environmental problems, including seasonal shortages, emergency storage, ground subsidence and saline intrusion.
