High-efficiency faucets in the bathroom or a faucet aerator can reduce water flow by as much as 30% without significantly reducing performance. The result is an annual water savings of up to 30,000 gallons. If every one of the 222 million bathrooms in the United States was retrofitted with an efficient faucet aerator, the result would be a saving of over 60 billion gallons of water. If all faucets in the home were retrofitted with aerators, the savings would be more than 300 billion gallons of water, translating into $2 billion annually. Installing a new water aerator is quick, easy and very inexpensive, literally costing just dollars. In fact, they are so inexpensive; not replacing an older aerator is actually costing you more money.
