Kingdom loses 30% of groundwater: Expert
Published in The Saudi Gazette on 28 - 09 - 2010

Saudi Arabia, the biggest Arab economy, is wasting as much as 30 percent of its finite groundwater resources by using outdated extraction methods, according to a water expert.
“Saudi Arabia could reduce the amount of water wasted to 5 percent if it changed technology,” Mansur Abahusayn, a visiting scholar at the University of California, Irvine, Urban Water Research Centre, said at a renewable energy conference in Abu Dhabi on Sunday.
“Groundwater is under very heavy pressure because Saudi Arabia has a large inland population.”
Saudi Arabia's eight aquifers contain 1,825 billion cubic meters of water, Abahusayn said.
This will run out within 200 years at current usage rates, whereas new technology would allow the country to conserve supplies for 400 years, he said.
Domestic use of oil and natural gas is growing faster than the Kingdom's population and economy, central bank Governor Muhammad Al Jasser said on Sunday.
Replacing groundwater with desalinated water, produced hundreds of kilometers away at the coast, would cost SR8.8 ($2.35) per cubic meter, Abahusayn said.
The Kingdom used 5.5 million cubic meters a day of potable water in 2007, Abahusayn said.
This will rise to 9 million cubic metres a day in 2015, and 13 million by 2039, he said.
About 55 percent of the supply comes from seawater, while the rest is from groundwater, he said.
However, in a study to be presented at the SWPF 2010 slated at the Jeddah Hilton on Oct.3-6, Saudi Arabia is aiming at becoming a global leader in power, water and renewable energy.
The new study, carried out by Al Aghar Group, in partnership with the Saudi Water and Power Forum (SWPF), will reveal recommendations on how Saudi Arabia can become a leader in knowledge and innovation in power, water and renewable energy. – SG
