The estimated KD 8.7 million ($29 million) third phase of the project, part-funded by the Arab Fund for Economic & Social Development, will involve the introduction of new infrastructure and management systems, improving the quantity and efficiency of irrigation water from groundwater aquifers. Mott MacDonald will carry out surveys to provide an up-to-date groundwater model for a 500-hectare area. The company will also design, prepare tender documents for, and supervise construction of irrigated farm networks involving the drilling of 20 new bore holes, the digging of lined and unlined canals and design and installation of weirs and flood protection systems. The phase is scheduled for completion in the summer of 2004.
Mott MacDonald worked on the second phase of WHADP in the 1980s, carrying out the initial hydrological study as well as designing and supervising construction of the irrigation infrastructure.
