Talk:Nubian Sandstone Aquifer System

From Wikipedia, the free encyclopedia

"Containing an estimated 150,000 km³ of groundwater,[2] the significance of the NSAS as a potential water resource for future development programs in these countries cannot be overstated. Recently the Great Man-made River Project (GMMR) in Libya began extracting massive amounts of water from this aquifer, removing an estimated 6.5 million m³ per day." -This would seem to indicate that, assuming that the removal rate stays the same, and that all the groundwater is available for extraction. This water supply can last no longer than about 63 years. (150 000 000 000 / 6 500 000) / 365 = 63.2 years Likely it will be depleted before that time due to increased demand and extraction inefficiencies.Greenknight21 18:44, 1 November 2007 (UTC)
