This paper considers optimization models for water distribution network problems with reliability constraints. Conditions are presented for an optimal solution where each link consists of at most two pipe segments with adjacent diameters. A simple example is also given to illustrate the case where the proposed conditions do not hold and three nonconsecutive pipe diameters may be selected for a link in the optimal solution.
