WATERSAVE has released urinals that work without flushing. Uridan urinals save money by not using water. They are also cheaper to buy and install in new buildings than flushing urinals because they do not need cisterns, flushing valves, or water pipes.
Urine drains through a stainless steel cover and into an oil-covered waste trap, which acts like an S bend into the waste pipe. A floating layer of biodegradable vegetable oil in the trap covers the urine and eliminates odours. The urinals are easier to clean and maintain than ordinary urinals because they do not have a flushing rim and the lack of water prevents the build up of ammonia and bacteria.
They available in fibreglass or porcelain, and last at least as long as ordinary urinals.
