Perhaps you have heard about campuses switching out the shower heads in their dorms to low flow shower heads. Why are they doing this? According to the U.S. Department of Energy, low flow fixtures and showerheads can achieve water savings of 25-60%. Low flow shower heads also reduce fossil fuel use because showers usually have hot water heated by coal fired electricity or natural gas. Savings such as this can be achieved by purchasing a shower head with a flow rate less than 2.5 gallons per minute (gpm), which is also now the federal regulation for new showerheads. How do you tell if your shower head is not up to standard? If you have a shower head that predates 1992, you should change it because before that time, flow rates were at 5.5gpm. Another simple way is to place a bucket under the shower head marked by gallons. Turn the shower head on and count how many seconds its takes to fill up 1 gallon. If it takes less than 20 seconds to fill up a gallon, it may be time for you to consider buying a new showerhead.
Other ways you can save money and water include fixing water leaks, changing the aerator (the screw-on tip on a faucet) which controls the water flow, or replacing your dishwasher and clothes washer with energy efficient washers. These are more expensive, however the payoff will be beneficial. There are many ways to save water, so the next time you head home take a look around your house and see where you can save!
