Water Free Urinal How Does It Work

Waterless urinals divert urine through a one way valve into a trap this trap contains a chemical that is less dense than urine.

Water free urinal how does it work. The urine then passes through a sealing liquid usually a specially designed oil based fluid or simply vegetable oil and collects in the waste pipe below. Urinal designs differ by the technology in the drain. This helps reduce water usage and also the amount of liquid waste that is sent to the sewage plant for processing. Waterless urinals help in conserving water usage.

Waterless urinals divert urine through a one way valve into a trap this trap contains a chemical that is less dense than urine. Using waterless urinals is particularly helpful in areas that face draught conditions such as arizona and california in the us. Urine flows down the bowl of the urinal past a debris catching strainer. Their outflow pipes connect to a building s conventional plumbing system.

Inside of the ecotrap the urine moves through a floating layer of proprietary immiscible blueseal liquid which creates a barrier preventing sewer gases and urine odors from entering the restroom area. When the urine flows through this trap the liquid displaces the urine forcing it lower into the trap. The urine below the blueseal barrier over spills into the central tube and travels down into the drain line. Instead they drain by gravity.

Waterless urinals all use basically the same science. These urinals flush urine without the use of any water.
