Our houses are thirsty. The average household uses about 400 gallons of water each day, or almost $700 per year in water and sewer costs. Making a few simple changes, such as installing EPA-certified WaterSense products, could trim up to $200 from your annual water bill. Add to that energy savings from reduced costs to heat water, and your yearly savings could reach $300 or more per year.

  • Low-flow showerheads include technology that reduces the amount of flow yet keeps pressure up, resulting in shower streams that are powerful and satisfying. They cost from $10 to $150, and installation is an easy DIY job that takes only minutes.
  • Replacing your pre-1994, water-guzzling toilet with a low-flow toilet prevents $90 worth of water costs from being flushed away. HE (high-efficiency) toilets use compressed air and electric water pumps to flush with less than 1 gallon of water; older models required up to 8 gallons.
