Grey water recycling is an innovative system that recycles bath and shower water for toilet flushing. It"s simple to install, maintenance free and can reduce water usage by up to 30%. Water and waste that we discard can be recycled to provide a valuable resource. Waste water from baths, showers, washing machines, dishwashers and sinks is referred to as Grey Water, whilst waste from toilets is known as Black Water.
The grey water recycling system always ensures that there is enough water for flushing the toilet. If there is not enough bath and shower water available, then the system intelligently tops up the storage tank with mains water. The system is a great solution for both domestic and commercial uses.
Untreated grey water can be also be used for garden watering if used immediately after it is produced. The waste water from kitchen sinks and dishwashers is not usually collected as it is too heavily contaminated.
How it works
The grey water recycling system collects used water from around the house. The water is then put through a filtration and treatment system and is then pumped, via a header tank, to the toilet for flushing or to other areas. When the used water falls short the mains-water is used as a backup. There is also a procedure to protect the mains water against contamination by backflow.
Grey water from baths, showers and hand basins is treated with basic disinfectant or microbiological treatment as it is usually clean enough for flushing the toilet.
