Abstract

Conceptual modelling for improving quality of surface water abstraction in Jakarta, Indonesia M. Ikhwan', Y.R. Fares^ S. Smitrr* & J. Colbourne^ * Centre for Environmental & Water Engineering Research, Civil Engineering Department, University of Indonesia * Fluids Research Centre, School of Engineering, University of Surrey, UK ^ Thames Water Research & Development, UK Abstract The problems associated with the unsatisfactory state of water supply and quality within the Citarurn/Ciliwung catchment that feeds directly to the city of Jakarta are reported. The various complex mechanisms of waterways along with the dispersion pathways of pollutant discharges are discussed.
