Abstract: Water pollution is viewed crucial which its ill management will cause severe effect to human health, aquatic life and its surroundings. Recently, the amount of waste discharged into the river and its assimilative capacity has affected the quality of river water directly. Hence, this study aims to characterize the water quality of the Klang River using the Water Quality Index (WQI) calculation at three locations along the river. The characterization will be used to assess the River of Life project. The locations are at the upstream of the river commonly known as the Ampang River, the middle river near the Masjid Jamek of Kuala Lumpur and the downstream near the Klang Mosque in Klang. These three water samples are taken between 6thOctober and 31 of October 2015. There are eight times of sampling at each location. This research conducts five in-situ tests and five laboratory tests. The WQI is calculated considering six parameters: the dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, total suspended solid (TSS) and ammoniacal nitrogen (NH3-N). The finding shows that the middle part of the Klang River is the highest in terms of quality compared to the other parts. It is recommended that to achieve the Class IIB quality, the two regionals' STPs, which are Bunus and Jinjang, be upgraded
