The best solution to reduce water consumption for urinal flushing is to install waterless urinals. They operate using chemical-impregnated plastic pads, or a spring-loaded trap and a floating layer of oil as barrier. The best thing for the environment is to use the 'chemical-free', waterless option.

Prior to installation, waste pipes should be assessed and modified to remove any flow restrictions and thoroughly cleaned during retrofitting. Waterless urinals require specialised cleaning methods with compatible chemicals, and in some cases replacement of the liquid barrier or pad every couple of weeks.

Benefits

The advantages of waterless urinals are:

• Significantly lower cost: each flushing of traditional urinals requires 1.5 lires of water; waste entirely avoided in the waterless version
• Easy maintenance: quicky and easily done using a biological cleaner
• 100 % odourless and free of bacteria
• Conforms to LEED and ISO certification requirements
