A new integrated water extraction and distribution solution from British firm Lister Petter has been launched at Middle East Electricity 2011.

Significant savings in terms of cost and time are achieved through enabling a single shaft to be used for the exploration, testing and pumping phases of the process.

Lister Petter’s technology enables a single bore to be sealed off in various sections, preventing contamination of lower aquifers, which is a problem commonly associated with conventional methods.

With this new technology, the practice of boring four or five holes before potable water is found becomes unnecessary. Through the more efficient mapping of aquifers, it also provides better water management and reduces the risk of upper aquifers being exhausted.

For bore holes as deep as 400m, as each aquifer is reached, the water is tested, the aquifer resealed and the drilling allowed to continue. Conventional methods of drilling require a new hole to be drilled each time in order to prevent cross contamination.

“This holds huge implications for a range of organisations that rely on underground water for a variety of applications, from drinking water through to a vast array of commercial applications,” said Lister Petter Group director Bob Bell.

Now in its 36th year, Middle East Electricity 2011 comes at a time when the UAE is expecting primary energy demand to increase by 71% by 2019.
