  • Water has been considered as the most preciouscommodity on earth since the beginning of humancivilizations. It holds a special place in Islamic tradi-tion as it is considered to be the source of life andthe medium through which humans cleanse theirbodies and souls before prayer.

    In arid areas such as the UAE and the rest of theArabian Peninsula, water has played a central rolein the culture, as it determined where human set-tlements would establish their trading routes andanimal grazing grounds.

    Today, UAE, as with the rest of the GCC coun-tries is almost totally dependent on the desalina-tion of sea water to produce fresh water which isbrought to consumers, often over a network ofpipes that extend for hundreds of kilometers.Although the effort and pain of securing freshwater for daily requirements have disappeared,with it has come the complete dependency andreliance of the government to provide desalinatedand reconstituted water at a cost that exceeds thecost of any water in the world.

    As the population expands and the demand forwater rises, the ability to expand to meet thegrowing need by building additional desalinationplants become more difficult not only due to thecosts involved but also for the impact such plantswill have on the environment. Desalination createsa double impact, both in terms of consuming ener-gy and thus the release of carbon dioxide as wellas the release of warm and salty effluents that con-tain the byproducts of disinfection into the oceanthereby harming our fisheries and the marine envi-ronment.

    In our analysis for the water supply and demand,we have learned that perhaps as high as 40% of theproduced water is unaccounted for. Some of thatmay be attributed to illegal connections which arebeing addressed by the installation of more watermeters. However, leakage, breakage and failure of

    materials are also a major cause of the loss of sucha high percentage of the produced water. Factorsthat contribute further to this loss include poorquality of materials, poor designs of internal watersupply networks and substandard performance bycontractors.

    With a view to learn from the experience of othergovernments worldwide, we were impressed withthe efforts made by the Orange County inCalifornia to cope with their problem of meetingdemands for high quality water and ensuring asecure supply to its constituency. Orange Countyhad sought assistance from the InternationalAssociation of Pluming and Mechanical Officials(IAMPO), an organization with over 80 years ofexperience in providing guidance to governmentsand industries for the protection of public healthand safety.

    The EAD contracted IAMPO to develop a plumingcode for Abu Dhabi built along the lines of theprinciples from the Orange County Pluming Codethat can serve as a guidebook and manual forselection of materials, design of networks, qualityof workmanship of water supplies and the wastewater collection systems inside buildings.

    The code is hoped to enhance the efforts of gov-ernment officials and contractors in providing oursociety with a safe, reliable, as well as an efficientwater supply and sanitation system for our homes,government, commercial buildings and to theindustries.

    On a final note, May I emphasize that Codes andmanuals alone cannot solve the problem of waterloss in our water distribution and waste collectionsystems. It takes dedication, hard work and perse-verance on our part as government agencies andpublic servants in addition to the commitment wecan acquire from our contractors to produce thequality of workmanship worthy of admiration byour people.
