Présentation
Water scarcity aggravates in coastal zones which are characterized by high population density, intense economic activity and tourism, and consequently facing a heavy seasonally variable water demand. The usual way to tackle water demand is to attempt to satisfy it through adopting supply-side measures such as increasing the abstraction from conventional surface and ground water sources. However, due to increasing limitation in water resources, a shift is taking place towards integrated water resources management (IWRM). IWRM adopts a holistic approach to optimize water usage. IWRM has to take into account the following four dimensions : water resources, water users, spatial and temporal scales. It critically assesses supply options, including developing alternative water resources, e.g. desalination (removal of dissolved minerals including salts) and reclaimed wastewater. It also seeks to increase the management efficiency of conventional resources and schemes. Finally, and importantly, an IWRM approach will also consider demand management options. IWRM projects should be sustainable and fulfil the public interest : maintenance of environmental quality, financial sustainability, good governance, institutional capacities and social equity. However, the development, decision making process and implementation of projects conforming to the IWRM approach are complex due to the different sectors involved, typically water, environment, energy and agriculture. The scope of this study is to develop a technical-economic modeling tool to aid decision makers, both public and private sector investors, in the design and assessment of the financial and environmental sustainability of integrated water resources management projects for tourism-dominated arid coastal regions. Designed projects are to satisfy varying temporal and spatial demands and to find sustainable solutions, which may include a higher level of wastewater reuse. The decision maker using the technical-economic model can be a hotel, a water company, or a water management company (i.e. municipality, city, town, and governorate). The water management company is assumed to perform integrated water management including : supply of potable water, collection and treatment of wastewater, and reuse of treated wastewater for irrigation water supply
