Advanced water conservation techniques include two strategies, minimum-flow fixtures or water reuse systems. This article reviews the use of these two conservation techniques, their potential effect on user services, economic considerations, and examples of applications. Daily water demands in homes, motels, offices, and other domestic facilities could be reduced by 50 percent or more through utilization of minimum-flow fixtures or water reuse systems. For individual domestic users, minimum-flow fixtures are usually more appropriate than water reuse systems, because they are easier to install, operate, and maintain, have no health risks, and are lower in cost per unit of reduced flow. Dramatic reductions in water demand resulting from the use of minimum-flow fixtures can have a significant effect on water, wastewater, and energy services. Experience to date demonstrates successful use under a variety of circumstances, and that such fixtures are cost effective. Includes 38 references, tables, figures.
