NWC saves $693m by plugging water leaks
Network repairs help Saudi firm save 433MMcm/day over five years.
Saudi-based National Water Company (NWC), the biggest water supplier in the oil-rich kingdom, has said it has saved more than 433 million cubic metres of water over the past five years - worth some SAR 2.6 bn ($693mn) - thanks to network repairs made in Riyadh, Jeddah, Makkah and Ta'if.
The company said the savings were made possible by the NWC's application of radar technology, audio devices and the use of helium to monitor leakage for the first time in the Middle East.
Water savings in Riyadh during the first nine months of 2014, amounted to more than 38 million cubic metres, with a value of SAR 228mn, meaning that savings from 2009 until the end of September, amounted to 278 million cubic metres with a value of more than SAR 1.6bn from processing 228,000 leaks.
In Jeddah, savings during the first nine months of 2014 amounted to 12 million cubic metres with a value of SAR 72mn with 81,000 leaks repaired since 2009.
The company said in Makkah, 20 million cubic metres worth SAR 120mn was saved in the first nine months of the year, while in Ta'if it saved five million cubic metres with a cost of more than SAR 30mn.
In total NWC has addressed 358,000 leakages since assuming responsibility for water management and environment treatment in the four cities, it added.
Last week, National Water Company said it has begun the first phase of a SAR 1.8bn project to achieve a sustainable water supply in Riyadh.
The NWC said that it is currently completing the initial stages of the first phase of the project in western Riyadh which will provide 600,000 cubic metres of storage capacity at a cost of SAR 250mn.
The work will come online gradually, and is expected to reach maximum capacity by summer 2015, serving the west Riyadh neighbourhoods of Laban, Aeryjae and Tuwaiq, the company said.
