It certainly seems that in the future, the smart money will be on using resources efficiently. Recently, we volunteered our time to help give tours down at the local waste water treatment plant. The purpose of the plant is to treat ALL of the water that comes from our homes and office buildings (kitchens, bathrooms, laundry, etc.); not water from storm drains. The waste water treatment plant budget requires chemicals, electricity and manpower that will treat ALL of the water that is pumped to the plant. So how much does that leaky faucet cost? Click here for a nifty tool from the American Water Works Association that will tell you how to calculate the annual volume of water that is lost by a leaking faucet. Those small leaks really add up!
PS - The tool just calculates the annual volume of water lost, it does not account for the other resources that are also wasted such as: treatment chemicals, manpower and the energy required for effective water treatment. YIKES!
