water saving system for washing machines


Two drops is a water-saving compact system based on the washing machine with reservoir of greywater, derived from hand washing in the sink. Our proposed product enables multiple use of water, that normally would be removed to the sewage system as a waste, what results in better water usage and saving money for its consumption in statistic family. Applying two drops system in daily use could help to save up to 30% of consumptive water and decrease waste volume to 70% normal production. An additional benefit of proposed solution is reduction of bathroom space needed for particular sanitary facilities (beneficial in small bathrooms), thanks to combining sink and washing machine.
