Composting toilets can dramatically cut down water use, although some require electricity to work.

Usage Tips

  • Do the dual flush conversion. While a new dual-flush toilet can be expensive, kits are available to convert any toilet into a dual-flusher. These toilets can help save water by using less for liquid waste flushes.
  • Fix leaks. Toilet leaks can cost you up to 200 gallons of water each day, the same amount it would take to wash 10 loads of clothes in an Energy Star-rated washing machine.
  • Keep it clean: Don't use your toilet as a trash can. Toss dead bugs and tissues into the compost pile or trash. Extra junk in your wastewater means more energy spent to clean it at the sewage treatment plant.
