Short summary
Sectorizing a network into district metered areas is a key technique for water loss reduction. Sectorization is a well-studied problem. Optimization techniques can be used to find solutions to such problems, but doing so within a reasonable time remains a challenge. We introduce two heuristic tricks to modify a basic evolutionary algorithm that solves this problem. The tricks reduce the time needed to find good solutions but also lead to solutions that better match drinking water practice.
