Integration of treated wastewater reuse in sustainable water resource planning

This presentation introduces multicriteria decision-making (MCDM) methodology to develop an integrated water management plan at regional and national levels. The proposed methodology will incorporate conflicting objectives of the stakeholders such as regulatory agencies, industries, and consumers in the decision making process; possible qualitative and quantitative data on water supply sources including groundwater, treated wastewater use, surface and renewable water resources, and desalinated water; water demands for domestic, industrial, landscaping, and agricultural uses; and associated environmental and human health risks with each supply source. A step-by-step MCDM approach, with examples, will be presented in developing a national strategic plan for countries which are facing water crisis. The importance of the participation of the multiple stakeholders with conflicting interests, data requirements, and public awareness in water conservation measures for sustainable development will also be highlighted.
