Abstract
A waterless urinal has a fixture including a backsplash and side walls joining a bowl at the bottom. Mounted on the top of the fixture is a fluid reservoir, a valve and a controller. The controller periodically opens the valve to release a quantity of a cleansing sealant from the reservoir onto the non-wetted surfaces of the fixture. The cleansing sealant cleans the non-wetted surfaces and then flows into the bowl where it collects to replenish the trap seal.
