Objectives

To present an overview of use of treated
wastewater effluent as an alternative
water source; potential to reduce water
footprint

To highlight the strategic approach
for water reuse initiatives in Malaysia

Introduction
• Malaysia Vision to become a fully
developed country by the year 2020.

• Rapid development has taken place
in sectors like agriculture, industry,
tourism, manufacturing and
urbanisation.

• All these development would not
be possible without adequate
water resources.

• Despite the country’s wet humid
equatorial climate regime, many
parts of the country suffer from
periodic water stress, primarily due
to:
• Imbalance water demand in
varying locations and sectors.
• Changes in weather pattern
affect trends in precipitation &
temperature.

Need Statement
National Water Resources Study (2000-2050) – Water Stress States
Penang, Melaka, Selangor , potentially N. Sembilan.
Rapid Urbanization and Industrialization.
During Dry season, water shortage & rationing
To cope : Inter State supply; demand management;
& efficient water use i.e. water recycling
NEED TO REDUCE WATER ABUSE
Potable water for Potable Uses
