Reduced water demand. Reduced water and electricity bills.

These appliances have very fast ROIs and should be used universally. Cost associated with potable water supply and sewage infrastructure are projected to escalate, most rapidly in developing countries. Dual-flush toilets require instructions in public locations to assure correct use. Waterless urinals require appropriate maintenance to avoid problems associated with smell.
Examples of quality water efficient appliances include but are not limited to: Toto or Sloan low-flow water closets and Falcon or Sloan waterless urinals.
