This system operates by collecting water from roofs, storing it in an underground tank and pumping it up to a feeder tank. An on-demand pump is used to supply water from the rainwater tank to wherever there is a demand for the water.
The system can provide water to replace up to 50% of mains supply for non-potable water use; Toilets, washing machines and garden watering can all use water from the rainwater system. The system will reduce the water needs by 10-15% and therefore allow the hotel to cut its water purchases.
