Groundwater - Akademi Sains Malaysia

Sarawak
• The first recorded abstraction of groundwater by tube wells in Sarawak
was in 1954 in Sarikei followed by similar schemes in Bintangor and Sri
Aman.
• Groundwater is presently the main source of water supply in several
coastal villages such as Belawai, lgan, Oya, Kabong, Pulau Bruit, Tatau,
Limbang and several other new schemes under development.
• Investigation and development of groundwater resources by the JMG
Sarawak have developed d in the seventies, 13 areas of groundwater well
fields for reticulated water supplies in the coastal region of Sarawak. A
large groundwater scheme in Lambir has been developed to augment
the Miri Water Supply. During the water crisis in 1997, groundwater has
become the new source of water supply when the surface source from
Sg. Liku was greatly reduced.
• 3 categories of aquifers:
shallow aquifers (sand, gravel and peat),
deep aquifers in sedimentary basins and
deep aquifers in fractured hard rocks.
• To date, about 0.05 million m 3 /d of groundwater is being exploited in
Sarawak.
