Abstract:
A water quality management system for managing the quality of water in a water supply network having water pipe lines running from a purification plant to consumers' faucets, comprising:a water distribution facility installed at a base point of a small-pipe water distribution network to improve the water quality, the small-pipe water distribution network branching from a water distribution main and running toward the consumers;water quality monitors installed in the small-pipe water distribution network to measure the quality of water; andflow sensors to measure the flow of water running through pipe lines of the small-pipe water distribution network;wherein means are provided for calculating an estimated value of residual chlorine concentration in the water reaching a vicinity of the consumers in said small-pipe water distribution network based on the quality of water measure by said water quality monitors and the flow of water measured by said flow sensors, and then controlling water quality at an outlet of said water distribution facility such that the residual chlorine concentration value at said vicinity of the consumers faucets is maintained within a predetermined range.
