This paper summarizes the water use measurements made in 96 homes served by three
U.S. water utilities before and after each had its interior fixtures and appliances
replaced with high efficiency devices. The purpose of the research was to obtain reliable
measurements of household water use for the major end-uses before the new devices
were installed, and then obtain paired measurements on the same homes after the retrofits
in order to get accurate data on water savings. Water use was disaggregated into end uses
by flow trace analysis. Statistically significant reductions were found for toilets,
clothes washers, leakage, showers and faucets. Using the water use and survey data,
mathematical models were developed that show household water use before and after the
retrofits (and water savings) as a function of several explanatory variables including:
number of residents, size of homes, cost for water, and whether retrofits had been
performed. Includes tables, figure.
