High efficiency clothes washers and dishwashers save water and save energy. They can cost a bit more but you'll enjoy significant savings on your water and energy bills that will really add up over time. EPA's website lists participating manufacturers.

The toilet is the single biggest water user in your home. Flushing accounts for about 38%, more than a third, of the water used within your home each day. Replacing an old model toilet with a new low-consumption toilet could automatically and permanently cut your home water consumption by 25% or more.

The Massachusetts State Plumbing Code requires that all new or replacement installations of two-piece tank-type and floor-mounted flushometer toilets use no more than 1.6 gallons per flush. These toilets are called low-consumption, low-flush, or ultra low-flush. Since all low-consumption toilets do not perform equally, consumers should make informed purchase decisions. This information will be helpful, but should not substitute for the professional judgment of a licensed plumber or engineer.


Thinking about replacing that old, worn-out clothes washing machine? High efficiency clothes washers save water, energy and space in your home. Most are front-end loaders that use tumbling action to get clothes clean. Look for the Energy Star Label to ensure that you're buying the most efficient product possible. Consider this:

  • High efficiency clothes washers use 30% - 50% less water, that's 5,000 gallons per year!
  • They use 50% - 60% less energy to run.
  • They require 1/3 less detergent.
  • Your clothes will get less wear and tear in a high efficiency washer.
  • They'll need less time in the dryer, too.


You can spend less money on water and spend less time in the kitchen if you switch to a high-efficiency dishwasher. Again, the Energy Star label will point you to the best water-savers.

High efficiency dishwashers use about 6-10 gallons of water per load of dishes (some use as little as 3.7 gallons!). Compare that to 9-12 gallons per load for average dishwashers and 20 gallons for hand washing.
Many newer models require little or no pre-rinsing of dishes – that's more water and time saved.
