This program describes how to build a system to catch, store and reuse the rainwater for irrigation in a high tunnel. Shawn Shouse, ISU Extension and Outreach ag engineer, runs us through the process. The cost of installing rain gutters, rainwater storage tanks, and an electric pump is estimated at $1,200. A solar-powered pumping system will add approximately $700 to that cost.
