When fully loaded, modern dishwashers are far more efficient than washing by hand: they use less water, energy and detergent. When loading the dishwasher, just scrape any large food scraps from dishes instead of pre-rinsing. Pre-rinsing wastes water and is unnecessary with modern dishwashers. If you only have a few dirty dishes to be washed, hand washing is the better option.
If your club washes its own uniforms, be aware that front-loading washing machines are more efficient than top loading machines with water, energy and detergent. This is because having the washing drum horizontal allows water and detergent to be circulated through the clothes more effectively.
Water Efficiency Labels
When purchasing a dishwasher or washing machine, be sure to check its WELS rating (Water Efficiency Labelling Scheme) before purchasing - not all appliances are created equal! The more stars a product has, the more water efficient it is.
Saving Water AND Electricity
Being water efficient does not only mean a reduction in water and its metered cost, it can also save hard cash on your water heating bill. The more efficient an appliance is (or any water-using system for that matter), the less water needs to be heated, thus reducing costs even further. By upgrading all appliances and bathroom fixtures to highest water efficiency standards, you may even be able to reduce the size of your water heating system, which will keep running costs lower at all times.
