More Information
Problems with Urinals
- Urine itself is not the main source of the problem.
- Urine is almost 98% water, mild in colour and is usually sterile.
- Problems begin when bacteria bind with the solids found in urine.
- Offensive smell we associate with urinals occurs when faecal bacteria digest uric proteins to give off toxic ammonia-based gases.
- Washrooms are covered with bacteria originating from faecal matter. Faecal bacteria become airborne when toilets are flushed.
- Bacteria settle on washroom surfaces and form bacterial colonies wherever this is a wet or damp environment, a food source, and protection from direct light.
- Water Creates an Ideal Environment for Bacteria
- Excessive flushing creates permanently damp surfaces on which bacteria colonies grow.
- Hugh volume of water used to flush urinals adds to the problem by depositing calcium, salt, silica and lime scale (water scale).
- Water scale coats fledgling bacteria colonies in a protective shell. Bacteria and water scale continue to build up until they form virtually insoluble lump of uric scale, which is the chief source of offensive odours in urinals.
- Uric scale creates unsightly stains and can grow large enough to block pipes.
- Desert Waterless Urinal Cubes can disrupt the process of uric scale formation by reducing water usage dramatically.
A total of over 7.0 million litres of flushing water is saved every year, which equates to an annual reduction in CO2 emission of about 1.2 tonnes, equating to planting of 51 trees.
