Abstract : Rapid urban extension in Al-Dawadmi Town, near Al Riyadh, has led to a continuous increase of waste water from houses, industry, and commercial buildings. Because the town has no sewerage network, the waste water has been drained and accumulated in the shallow sedimentary layer that has a shallow bed rock. A continuous rise of the groundwater table has been expected to cause health, environmental, and infrastructural problems. To control the problem, installation of a drainage network has been considered and designed. In this paper, a finite element numerical model, MAWF has been employed to check the effectiveness of the network in lowering the rising groundwater table. It has been checked in a period of fifty years. Two scenarios have been considered. The first scenario traces the problem assuming no drainage pipes are installed. The second one checks the effect of the drainage network in lowering the groundwater table. The results of the study are presented in the form of contour maps and hydrographs. The results show that the drainage pipes are effective in lowering the water table by a depth of not less than 2.0m and keeping it steady for fifty years despite the increasing recharge rate.
