WATER BUILDINGS

Gray water recycling systems collect the water used in sinks, dishwashers, bathrooms and showers, clean it and use it for the toilet, dishwasher or the external irrigation faucet. 
Rainwater storage systems are a simple way of collecting rainwater, traditionally placed on rooftops, for later use in homes, as an alternative to the drinking water supply and thus, and for reducing consumption in the traditional water supply system.
