Uncontrolled urbanization and the growing population pressure are essential challenges for the water management in urbanized regions of the emerging- and developing countries. In terms of the environment, the reciprocal impact of urban development and groundwater represents one of the most important aspects of growing cities.The interaction between urban development and groundwater may be explained in the relation with the land use pattern and stage of city evolution on affecting the quantity and quality of groundwater (see Figure 1). Quantity and quality changes are caused commonly by the increase of groundwater abstraction and the existing of new sources of recharge Putra 2007). Important previous studies of the effect of fast growing cities on groundwater are given by Foster et al. (1993), Morris et al. (1994) and Vasqeuz-Sune et al. 2005. The main issues concluded from these studies are:
– Urbanized area changes groundwater recharge or cycle, with modification to the existing recharge and the introduction of the new sources
– Discharging of new sources of recharge in urbanized area causes extensive but essentially diffuse groundwater contamination.
– Fluctuations in groundwater levels and
– impact on engineering structure.
