520			_aAlthough arid and semi-arid regions are the most vulnerable regions to water scarcity, is witnessed that large amounts of fresh rainwater is lost by evaporation or to the sea. Further, floods frequently cause damage in cities and villages. Therefore, rainwater harvesting (RWH) may be a vital technology for securing alternative water resources in such regions. The underlying research aims at evaluating the present and future water situation in Ibb City, Yemen, and hence assessing the impact of RWH in closing the water gap. First, survey of available water resources and water demands in the study region has been carried out based on available data and studies from NWRA and IWSLC, upon which the present and future water deficit until 2050 has been determined. Further, a field survey has been carried out to assess water quality and consumer opinion. Except for biological parameters, it was found that all water quality parameters were within acceptable limits according to WHO and Yemen water law. The collected water would be suitable for drinking after use of a suitable filter and roof cleaning, a survey of available water resources and water demands in the study region has been carried out based on available data and studies from NWRA and IWSLC, upon which the present and future water deficit and based on a per capita water demand of 70 lpcd, water deficit has been estimated at 25% in (2015) and reaching 48% by 2050. In order to close this gap, the potential quantity of water that could be secured through water harvesting from the roofs of all buildings has been calculated through the utilization of GIS maps and the rational method. Further, a field survey has been carried out to assess water quality and consumer opinion
