Multiobjective analysis in water resource planning and management: A framework for policy evaluation

A multiobjective framework for the planning and management of a regional water resource system is presented, considering the conflicting objectives of environmental quality and the cost of water resource development. The regional water resource system is a complex, large-scale system and includes a number of proposed and existing water resource facilities (both water supply projects and wastewater treatment plants.) Treatment alternatives available at each wastewater treatment plant include secondary treatment, tertiary treatment, and recycling of treated effluent (at industrial plants only).
