A small leak that fills a coffee cup in 10 minutes wastes 3,280 gallons of water a year. If it's hot water, you're wasting energy as well. Dishwashers use approximately 15 gallons of hot water per use. That's why you should always wash a full load of dishes. Washing dishes by hand could use as much as 20 gallons.
Showers generally use less hot water than a tub bath.
Installing energy-saving shower heads can save 6 to 8 gallons of water per minute. Buy the proper size equipment to meet your family's needs. An oversized furnace wastes energy. Read appliance manuals carefully and follow instructions. Replace old, outdated appliances which use more energy than new, more efficient appliances.
