Frequent Floods
21Flood prone areas 29,720 km² (9 land area)
22Direct and indirect economic losses
23Floods
- Floods exacerbated by
- Disposal of solid wastes into waterways
- Sediments from land clearance and construction
areas - Increase in impervious areas
24Encroachment of River Reserves
25Squatters
26ISSUES CHALLENGES
- Flooding
- Water Shortages - Drought
271998 drought caused serious water rationing and
hardship for 1.8 million residents of Kuala
Lumpur other towns in Klang Valley
28Water Crisis

30Water Shortages
- Growing demands and pressure on water resources
- Per capita availability of water is decreasing
- Reaching practical limits of surface water
resources development - Inter-basin and inter-state water transfers
31Projected Water Demand
include losses

53Institutional and Legislative Issues
- Malaysian Constitution
- Land and water state matters
- Rivers within jurisdiction of State
- Many state laws outdated, redundant or ambiguous
conflicts / overlaps common - Lack of comprehensive national river law
- Federal, State, Local governments involved in
various aspects of water
54Institutional and Legislative Issues
- Numerous Ministries and Departments
- regulate manage various water sectors
- duplication of efforts gaps
- competition and conflict
- Inadequate financial allocation
- Emphasis on resource utilization rather than
resource conservation - Insufficient stakeholders/public participation

- To create and promote awareness among the public
to take care and love the rivers and the
environment the importance of rivers in the
individuals daily life. - To increase the awareness among the public on the
need to conserve the natural environment and
preserve rivers. - To increase the knowledge and techniques of river
management and the catchment area among agencies
involved

98Long Term Plan IRBM
99River Basin Master Plans provide overall
framework for development in a river basin
100National Water Resources Council at its meeting
on 29 July 2003 agreed to the preparation of
River Basin Master Plans
101What is IRBM ?
- Integrated River Basin Management is the
sustainable management of land and water based on
natural geographical boundaries, rather than
administrative units.
102IRBM
- River Basin
- Geographical area determined by the watershed
limits of the system of waters, including surface
and underground waters, flowing into a common
terminus.
103Sungai Kelang Catchment
- 8 PBT, 2States
- Ampang Jaya
- Ulu Langat
- Gombak
- Wilayah Persekutuan Kuala Lumpur
- Petaling Jaya
- Subang Jaya
- Shah Alam
- Kelang
Each manages the water resources (water supply,
pollution, and floods) sectorally and
individually.
104Components of IRBM
- Political Support
- Inter-agency collaboration
- Resource management
- Regulation / Legislation
- Governance (stakeholder participation)
- Financial sustainability
105Status of IRBM
- IRBM Plan for Sg. Kedah and Sg. Selangor in
progress. (2002-2007). - Blueprint for IRBM plan being prepared.
- Proposal to State Governments to form Water
Resources Board / Authority and to gazette river
reserves. - Proposal to Federal Government to place rivers as
concurrent list with the intention to finally
draft a River Law to govern all activities in a
river basin.
