The situation experienced by the impression of a water crisis in Malaysia

Causes of the water crisis in Malaysia

Deforestation in water catchment areas

Weather phenomena such as drought and El-Nino
Malaysia's rivers are heavily polluted due to waste and industrial
waste
High demand from the industrial sector (ex: factory)

The use of chemical and pesticides in agriculture

An increase in population causes the demand for water to increase
7

Water-saving Control waste Replacement of
campaign disposal, logging old pipes to avoid

Advancing the source activities and water wastage
of soil water is forest exploration due to pipe leaks

because it is easy and Measures can be
cheap to use taken to address the

shortage of water
supply in an area

Cloud seeding to
produce artificial

rainfall in
catchment areas

1 . Water usage/Penggunaan air (m³)
= 1218-1197
= 21.00

2 . 20.6660 m³ X RM 0.80 = RM 16.53
0.3340 m³ X RM 2 = RM 0.67
