New Year's Resolution: Save 1,000 gallons of water each month! It's easier than you think. Just replace your old shower head and shave one minute off your shower time- that's it! Older shower heads use between 4 and 7 gallons per minute (gpm). A new one will run about 2.5 gpm. Let's assume a two-person household with each person taking 25 showers a month. If they each take 8-minute showers using a 4.75 gpm shower head, they are using 1,900 gallons on water each month. However, by taking 7-minute showers using a 2.5 gpm shower head, they would use only 875 gallons per month. That's 1,025 gallons of water saved each month, and 12,300 gallons saved each year! Shower timers are a great and inexpensive way to keep track of your shower time. As you can see, a little effort goes a long way. So shower smart this year and save!
