Big Savings from Waterless Urinal
waterless urinal that not only saves an average of 45,000 gallons per year (see table, page 6), but also has no valves to clog or break and may actually be more hygienic than conventional urinals.
Here’s how this ingenious system works: urine flows into the EcoTrap®, where it passes through a lighter-weight liquid, which this trademark-happy company calls BlueSeal® (see diagram). The layer of BlueSeal provides the trap, effectively keeping odors from escaping into the room. The toilet is plumbed to a standard drain line (not copper). A water supply line is not needed because this is a non-flushing urinal. In fact, there are no moving parts at all to fail.
