Many countries are struggling with managing their water supplies due to various reasons including lack of rainfall, limited space for reservoirs and lack of natural water resources. Many appliance manufacturers are helping to conserve water by introducing water efficient appliances, mainly dishwashers and washing machines. The governments of many countries now rate the water efficiency of appliances along with offering incentives to buy these machines. Water conservation will continue to be an ongoing effort in many countries so these appliances will become even more efficient in the future.
