BLOOMINGTON, Ind. -- Want to conserve water and save on your utility bill? A paper co-written by an Indiana University researcher and published in the current issue of the journal Environment can help.
"The Water Short List: The Most Effective Actions U.S. Households Can Take to Curb Water Use" describes how households can reduce water use substantially by simple actions such as installing more efficient appliances and changing day-to-day habits involving water consumption. While the suggestions may be familiar, the researchers are the first to put a comprehensive, quantitative estimate on the amount of water savings available to a typical household. They also find that some frequently discussed conservation steps actually consume more water than they save.
Authors of the Environment cover article are Benjamin D. Inskeep, an energy policy analyst with the N.C. Clean Energy Technology Center at North Carolina State University, and Shahzeen Z. Attari, assistant professor in the School of Public and Environmental Affairs at IU Bloomington. Inskeep recently completed a master's degree at the School of Public and Environmental Affairs.
"As water availability is expected to become an increasingly urgent issue in the coming decades," they write, "it is heartening to find that substantial reductions in household water use are readily available to U.S. households."
Inskeep and Attari address potential savings of both indoor and outdoor water use, focusing on efficiency improvements though one-time technology upgrades as well as curtailment actions. Drawing on data from the Water Research Association and the U.S. Geological Survey, they estimate indoor water consumption can be reduced by 45 percent through efficiency actions such as installing efficient toilets, washing machines, dishwashers, showerheads and faucets. For example, replacing a standard toilet with a WaterSense-labeled toilet could save a family a whopping 1
