This study was part of a comprehensive water conservation program sponsored by HUD through the Center for Building Technology (CBT). The purpose of this study was to identify appliance parameters, usage techniques, and options available to manufacturers and consumers that offer the most substantial water savings. Appliances considered were clothes washers and dishwashers. Through a comparison of estimated water savings, the study indicates that the most significant means of saving water are those that are already commercially available -- front-loading machines and suds-saver options for clothes washers and short-cycle settings for dishwashers. Water savings of about 20 to 30 percent are estimated with these features, or aout 10 gallons for clothes washers and 3 gallons for dishwashers.
