AB  - The optimal design of multicontaminant industrial water networks according to 
      several objectives is carried out in this paper. The general formulation of the 
      water allocation problem (WAP) is given as a set of nonlinear equations with 
      binary variables representing the presence of interconnections in the network. 
      For optimization purposes, three antagonist objectives are considered: F(1), the 
      freshwater flow-rate at the network entrance, F(2), the water flow-rate at inlet 
      of regeneration units, and F(3), the number of interconnections in the network. 
      The multiobjective problem is solved via a lexicographic strategy, where a 
      mixed-integer nonlinear programming (MINLP) procedure is used at each step. The 
      approach is illustrated by a numerical example taken from the literature 
      involving five processes, one regeneration unit and three contaminants. The set 
      of potential network solutions is provided in the form of a Pareto front. 
      Finally, the strategy for choosing the best network solution among those given by 
      Pareto fronts is presented. This Multiple Criteria Decision Making (MCDM) problem 
      is tackled by means of two approaches: a classical TOPSIS analysis is first 
      implemented and then an innovative strategy based on the global equivalent cost 
      (GEC) in freshwater that turns out to be more efficient for choosing a good 
      network according to a practical point of view.
