Rain Water Harvesting in a University Setting

Rain is a resource. Collecting it for use is one of those very old ideas that we are rediscovering as we strive to preserve our environment. Recent projects at universities across the country show that laboratory facilities can practically collect, process, and use rain water to reduce the load on the municipal water supply.

This presentation includes:

  • A description of a few installed systems covering collection, treatment, and distribution equipment, along with the instrumentation and automation required.
  • Design issues such as sizing, selection of water treatment processes, and intended use of the greywater in the context of individual projects.

Operating results indicate that rain water harvesting has led to water savings in climates from the Pacific Northwest to Atlanta, where the current drought has lasted for several years.
