Developing Data for Residential Water Savings
Author: William O. Maddaus, Jerome H. Rothenberg

Demonstration projects are being conducted for the U.S. Department of Housing and Urban Development (HUD) to document water savings in actual homes. Arrangements to conduct demonstration projects have been made with the City of Atlanta Bureau of Water, Denver Water Board, Los Angeles Department of Water and Power, and the Washington Suburban Sanitary Commission. Projects were selected on the basis of estimated water savings, need for field data, cost, and other factors. The following demonstration projects were selected: studies of contemporary and advanced low water using bathroom fixtures; a study of water- and energy-efficient homes; the effect of retrofitting on hot water and energy use; the effect of metering; the effect of a pressure change; a nationwide leak detection survey; nationwide surveys of water-using fixture use and shower water use characteristics; and the long-term effectiveness of retrofitting in various cities. Each project involves a test group of dwelling units, equipped with the water conservation device, and a control group for comparison. Results will be published in 1982 and 1983.
