Abstract: One of the overall objectives of River of Live (RoL) River Cleaning Task Force leads by Department of Irrigation and Drainage Malaysia (DID) is to improve the river water along the 10. 7km of Gombak River and Klang River from the current Class Ill to IV to Class llB water quality. Many key initiatives have been identified and among them is to implement Interceptor Systems along the whole 10. 7 km stretch. The purpose of the Interceptor Systems is to intercept the polluted sullage drainage discharges along both banks of the 10. 7 km rivers so that they can be conveyed to suitably located treatment plants for purification and release back to the rivers subsequently. This paper highlights the criteria and assumptions adopted, the analyses used in designing the systems and the challenges faced during the design stage. Generally, it is important to establish suitable criteria and assumptions to be adopted for a project after the conceptual design is formulated and before the start of any analyses and design work commence. With the criteria and assumptions defined, hydrological and hydraulic analyses are carried out to determine the size, configuration, type, etc. for each of the components that form the integral Interceptor System. This involves using various analytical computer models and spreadsheets to derive all the required parameters. Similarly for the Sullage Water Treatment Plant (SWTP), analytical model is also adopted to estimate the size and dimensions of the holding storage and treatment media required. Implementing a major system in the highly urbanised areas often need to deal with various challenges. These include space constraint, land acquisition, relocation of utilities, traffic and accessibility during construction, river conditions and other on-going works such as the beautification works by Kuala Lumpur City Hall (KLCH)
