Most urinals in use today use somewhere between 1 and 3 gallons (3.7 to 11.3 liters) of water for each flush [source: Reichardt]. That variance is so large because older urinals use a lot more water, and newer ones tend to use less (because of an increased focus on conservation).
How much water is used to flush a urinal in Litres?
The 1999 Water Regulations stipulate that there should be a maximum water usage of 7.5 litres per urinal bowl per hour and that a device should be fitted to prevent the urinals flushing when the building is unoccupied.
How much water does each flush use?
Flushing is the biggest water hog in the house. Older, conventional toilets can use 5 to 7 gallons per flush, but low-flow models use as little as 1.6 gallons. Since the average person flushes five times a day, the gallons can really add up.
