As part of the optimization data, the user specifies the pipe sizes to be considered for each group. For example pipe selection for a group may be limited to 150, 200, 250 and 300 mm. Only sizes which are included in the discrete cost function may be specified. Each group of pipes can have different sets of sizes. In addition to specifying possible pipe sizes to be considered, the user can specify that the program can consider eliminating all pipes in a group (by assigning size 0 (zero) as a candidate size), or cleaning and lining the existing pipe(s), if there exists a parallel pipe (not to be sized) to each pipe in the group.
