While it may be obvious that no flush urinals will save fresh water, there are many other environmental and financial benefits to installing waterless facilities. Once you understand the benefits to your organization, you may be quick to change over to these environmentally and financially friendly concepts.
Reducing CO2 Emissions
By installing no flush urinals, you are saving between 9 and 15 L of water, moving through the regular system towards the sewage plant, just to move 300 to 400 mL of urine. When the two liquids reach the eventual sewage plant, they are treated before the water can be moved on for a secondary use.
The no flush urinals are moving less than half a liter of water to the sewage plant, therefore reducing, dramatically, the amount of treatment required, which rapidly reduces the CO2 emissions from the sewage plant.
Most water that is used in bathrooms is of a high enough quality to meet drinking water standards. Every time the flush sensor discharges water to clear the urinal, drinkable water is being wasted.
Some businesses think ahead and use treated and recycled water, grey water, to flush the urinals. Although this is better than pouring good quality drinking water direct to the sewage plant, the lower standard of water must still be treated when it reaches its destination.
Financial Saving
Urinals that do not use any water for flushing, show two direct benefits. Apart from the financial benefit, where the owner of the facilities uses less water in their organization and therefore reduces their annual water consumption, maintenance is reduced.
Lime scale and sediment from urine, specifically in hard water areas, are of the most substantial causes of blocked pipes and this follows with flooded bathrooms. Some organizations will increase the water flow to use more water and pay higher bills, to try and keep the pipes unblocked. This is a false economy as it only encourages the limescale to build up quicker. With waterless urinals, far less water moves through the pipes and is therefore less likely to require maintenance as early as any of the traditional waste methods.
