Abstract

A water-conserving system equipped to periodically rinse ultra high-efficiency urinal drainage plumbing of corrosive waste liquid and reduce associated gaseous odor is provided. A valve-controllable rinse-cycle supply of water is provided which can selectively be directed into a single drainage conduit which receives waste water from one or more ultra high-efficiency urinals. The system provides embodiments having mechanical valves, or electro-mechanical valves configured responsive to control-signals provided from one or more electronic components, or one or more types of microprocessor-enabled devices, networked devices or computer apparatus.
