Pareto-Optimal Cost Division for the Design of Sewage Water Treatment Plants by means of the DSS REH

The achievment of regional water quality goals often involves substantial capital investments and changes in public attitudes concerning resource management. The economic impacts may include not only the costs of facilities designed to reduce the discharge of contaminants into natural surface waters or to improve the quality of waste-receiving waters, but also any limitations on economic development in a particular river basin. Those responsible for the formulation and approval of water quality plans or management policies must have means of estimating and evaluating the temporal and spatial economic and environmental or ecological impacts of these plans and policies. This need has stimulated the development and application of a wide range of mathematical modeling and optimisation techniques for predicting various physical, chemical, biological and economic impacts of alternative pollution control schemes.
