This work evaluates the use of a device inspired by the human taste system to carry out quantitative and qualitative monitoring of drinking water samples. The results showed an excellent ability to discriminate the samples and predict some analytical parameters of interest in controlling their physicochemical quality. This made it possible to conclude that the device called smart electronic tongue has a high technological potential for monitoring drinking water.

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.
