Did you know?
The standard bathroom faucet uses 2.2 gallons of water per minute (GPM). Switching to a low-flow faucet aerator can reduce this to 0.5GPM, a savings of almost 80%. Under normal daily consumption patterns, this would save 8.5 gallons of water per day for each person using the faucet, or over 12,000 gallons of water in a year for a family that retrofits its faucets with low-flow aerators.
Here's a quick overview on faucet aerators. It's cheap, easy, and saves loads of water and energy (to heat the water) without placing any burden on you.
