Definitions

“River” means any river, stream, creek or other
natural water course, and/or any tributary,
distributary or artificial deviation thereof (National
Land Code 1965).

“River””means a body of inland water flowing for the
most part on the surface of the land but which may
flow underground for part of its course.

“River b
“Ri
basin”
i ” means the
th area off land
l d from
f
which
hi h allll
surface runoff flows through a sequence of streams,
rivers and, possibly, lakes into the sea at a single
river mouth, estuary or delta (Adapted from EU Water
Framework Directive 2000).

River Basins in Malaysia

List of River Basins - updated based on the
definition of river and river basin

Classify rivers into 3 categories - based on
the Provision of Federal Constitution
– Category 1 - river wholly within a state (state
river)
– Category 2 - river shared more than one state
(national river)
– Category 3 - river shared with other country
(international river)

Reforms in the Malaysia
Water Sector
In 1998,
1998 National Water Resources Council
(NWRC) has been set up.
 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.

RIVER CLEANING
In order to bring life to the river, pollution must be reduced and water must
be treated

1 Ammoniacal nitrogen (AN) is a toxic pollutant often found in sewage and landfill
2 Higher biological oxygen demand (BOD) BOD indicates higher presence of microorganisms, suggesting
higher pollution
3 Suspended solid (SS) is organic and inorganic particle (e.g., waste, sand) that increases turbidity and reduces
oxygen content

Conclusion
Policy – begin with Federal Constitution
Rightly placed policy will help in attaining water quality
target
Clean and beautiful river invites public appreciation of
water and nature
Generates country economy through eco-tourism and
inline with IWRM approach
Integrated Water Resources Management
(IWRM)
Defined as :
“the process that promotes the coordinated
development and management of resources in
the natural environment (water, land, flora and
fauna) in order to maximise the resultant
economic and social welfare in an equitable
manner without compromising the
sustainability of vital eco-systems”
(Integrated Water Resources Management, Global Water Partnership
Technical,Advisory Committee Background Papers, No. 4, 2000.)
