In the context of water scarcity in the Middle East, here are some suggestions for selecting water-saving toilets:
Water flow: Choose toilets with smaller water flow to reduce water usage during flushing. Toilets with a flow rate between 4.5 to 6 liters are usually water-saving.
Dual-flush toilet: Dual-flush toilets have two buttons to control flushing for solid and liquid waste, respectively. This way, users can choose different water volume for flushing, which saves water.
Dry and wet separation toilet: Dry and wet separation toilets treat faeces and urine separately, reducing water usage.
Turntable flushing toilet: Turntable flushing toilets have adjustable water pipes to control the flow rate according to needs, which can reduce water usage.
When choosing a toilet, the following factors should also be considered:
Price: A higher price does not necessarily mean better water-saving features.
Brand: Choose a reputable brand for guaranteed quality and longer lifespan.
Material: The material of the toilet should also be considered. For example, DuPont ceramics are known to be more water-efficient.
In addition to the above tips, seeking advice from professionals or relevant organizations can provide more useful suggestions.
