A flexible methodology to sectorize water supply networks based on social network theory concepts and multi-objective optimization
A novel methodology to sectorize water supply networks (WSNs) depending on a main transmission line is presented in this paper. The methodology is based on concepts derived from the social network theory and graph theory (namely, community detection and shortest path respectively); and also on a multi-objective optimization process by means of agent swarm optimization (ASO). A series of ...

Hutchinson Finds a Quick Reliable Fix to Cavitation Damage
The Hutchinson Kansas Water Plant gets its water from twenty wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back with the well water. This is used to lower the total dissolved solids ...
