Failed septic systems contaminate lakes and rivers with E. coli, viruses, and other pathogens. Also, nitrate leaching from septic systems threatens ground water in some locations. Finally, conserving water decreases the load on sewage treatment plants and minimizes the possibility of inadequately treated sewage reaching rivers and other surface water. Even though water is usually plentiful in Indiana, water shortages can and do occur. The Midwest and eastern U.S., usually water-rich regions, have recently experienced widespread drought.
Conserving water is always a good idea, but particularly necessary when water is scarce.
This publication examines water use in and around the home, and suggests ways for conserving water. Although these numbers are national averages, studies show wide variations in water usage between households. In general, urban households use more than rural households, with people in western states using more than in the eastern U.S. or Midwest. Also, less water is used in the early morning hours of the day and during the winter months. Peak consumption takes place in the summer, when lawns are often watered, and families return home in the late afternoon.
