Abstract	The minimisation of water and waster flows is an objective of increasing value in industries. The paper presents a systematic optimisation approach for the design of the water-using systems in process plants with minimum water usage and capital investment. The proposed approach combines the benefits of water-pinch concepts and mathematical programming techniques. It follows a two-stage procedure, namely targeting stage and network design stage. Both stages rely on the optimisation of a superstructure model with all possible connections between (i) freshwater sources and operations, and (ii) different water-using operations. The approach facilitates the inherent combinatorial nature of the design problem and solves it efficiently. © 2003 Elsevier B.V. All rights reserved.
