The rapid urbanization and industrialization in major Malaysian river basin involve a large portions of agricultural and ex-mining land are being converted for urban use. Growing demand to spur the economy is transforming the landscape into residential, commercial, industrial and institutional use.

As a result of the extensive development, river basins are being subjected to over-bank floods, flash floods due to clogged drainage systems and river environment degradation. This prompted the authority to adopt a new concept in the planning and management of urban storm water runoff. An alternative concept, which is newly introduced nationally, is based on control at source approach. The water quantity control is derived from multiple combinations of drainage system components that include elements of infiltration engineering, storage and flow retarding facilities.

The planning of storm water system needs to be undertaken in a safe and ecologically sustainable manner. Many of our rivers, lakes and coastal waters are currently degraded by urban storm water, due to excessive flows, poor water quality, and removal of riparian vegetation and destruction of aquatic habitats. The new approach is to broaden the storm water management to minimize the impact of urban storm water towards degradation of receiving water body. In order to meet the water quality control criterion, the storm water runoff is treated at source and the treatment facility is optimized according to the train of treatment concept inherent in Best Management Practices (BMPs).
