In 2003, the NWRC has decided that the formulation of Integrated River Basin Management (IRBM) master plans be carried out for all the 189 river basins. Cabinet Reshuffle in March 2004, – 11 agencies from 4 different ministries were combined in the Ministry of Natural Resources and Environment (NRE). Reforms in the Malaysia Water Sector (contd contd)) – the Department p of Water Supply pp y and the Department p of Sewerage Services were moved to the Ministry of Energy, Green Technology and Water. The Federal Constitution was amended in January 2005 to transfer matters related to water supply services from the State list to the Concurrent list. Th amendment The d enabled bl d the h F Federal d lG Government to regulate the water supply services while ownership and control of water resources, dams and catchment areas remained with the state governments. 10 The Federal Constitution of Malaysia List I - Federal List 9 Shipping, 9. Shipping navigation and fisheries, fisheries including (a) Shipping and navigation on the high seas and in tidal and inland waters; 10.

Federal works and power, including (b) Water supplies, rivers and canals, except those wholly within one State or regulated by an agreement between all the States concerned; production, distributions by supply of 21 water power; List II - State List 6. State works and water, that is to say (c) Subject to the Federal List, water (including rivers and canals but excluding water supplies and services); control of silt; riparian rights.
