Abstract
Regional wastewater-treatment strategies offer cost-effective options to meet
pollution limits in fast-growing urban areas. Formal optimisation procedures
have been applied effectively to solve relatively simpler versions of this problem.
Contemporary heuristic search procedures (e.g., evolutionary algorithms (EAs))
offer enhanced capabilities to solve more complex versions of th~s problem.
While these optimisation procedures continue to offer increased capabilities for
systematic search for efficient solutions, some decision criteria and issues are not
easily modelled. Optirnisation procedures can still be made useful if they can be
utilized effectively to generate in addition to the optimal solution a small number
of different alternatives that are near optimal. Alternatives with maximal
differences between t
