Water quality management system

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' faucet, 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;
• and
• water quality monitors installed in the small-pipe water distribution network to measure the quality of water;
• wherein the water distribution facility is provided with a water quality monitor, a means for improving the water quality and a bypass passage for bypassing the water quality improving means and delivering the water to the small-pipe water distribution network, and bypassing means operable such that the quality of the water entering from the water distribution main into the small-pipe water distribution network is measured by the water quality distribution facility monitor and, when the water quality is good, the water quality improving means is bypassed when the water is delivered to the small-pipe water distribution network.

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:

• water quality monitors installed in a small-pipe water distribution network to measure the quality of water in pipe lines, the small-pipe water distribution network branching from a water distribution main and running toward the consumers;
• wherein the quality of water flowing from the water distribution main to the small-pipe water distribution network is controlled based on signals from the water quality monitors
• further comprising:
• a pipe line for delivering the water near the water quality monitors installed in the small-pipe water distribution network to a water distribution facility, a water distribution reservoir or the purification plant;
• and
• a drain valve for opening and closing the pipe line;
• and means for opening and closing the drain valve according to signals from the water quality monitors.
