A new on-line water harvesting module created by The University of Arizona Arid Lands Information Center is available to the public free of charge. The module makes use of "how-to" video clips, photos, demonstrations, animations, and interactive quizzes to communicate simple principles of capturing rainwater for landscape use. The module was created by Theresa Crimmins and Katherine Waser and the team at the UA Arid Lands Information Center, supported by funding from the UA Water Sustainability Program.
This module is accessible at http://rwh.arid.arizona.edu and serves as a great introduction for anyone interested in simple rainwater harvesting techniques.
