Facilities dosing system

Abstract

A facilities dosing system comprises a signal-actuated valve controlling a flow of hot water from a water heater to one or more water fixtures that drain to one or more drainage conduits, and a controller configured to trigger opening of the signal-actuated valve, allowing for flushing with the hot water of the drainage conduits from the one or more water fixtures over a controlled period of time. A facilities dosing method comprises electronically controlling, by a system comprising a controller, flow of hot water from a water heater to a plurality of water fixtures that have automatically-allowed drainage to drainage conduits, and cyclically electronically triggering, by the system, the electronic controlling, for repeated flushing of the drainage conduits with the hot water, comprising bypassing cold water cisterns feeding the water fixtures.
