2.2.1 Water Efficient Appliances
Reduce water demand by ensuring the installation of water efficient appliances and fixtures.
Make use of dual-flush toilets, waterless urinals, aerated shower heads and faucets, high-efficiency clothes washers/dishwashers and flow restrictors for showers and basins.
Commercial, residential and industrial appliances can greatly impact water demand, depending on program and use. Specify appliances that meet the industry’s highest water efficiency ratings.
Ultra low flush toilets use 67 percent less water than standard 20L models. Efficient dishwashers use 39 percent less energy to heat the water and 50 percent less water than standard models. Energy savings of 68 percent can be achieved with efficient clothes washers and 38 percent water savings compared to older, standard models. 0 to 3 years ROI. (Source: www.epcor.com)
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.
