Aim to take shorter showers, since cutting your shower time in half can reduce your water costs by 33%. Run the dishwasher only when it is full. When it's time to replace your clothes washer, consider buying a front loader machine. Also, when doing laundry, set the water temperature to cold. Unless your clothing has oily stains on it, cold water will wash them just as well as hot water. Using a cold water detergent will also help get clothes clean.
