Iowa State University Extension is making available Rainwater Catchment from a High Tunnel for Irrigation Use, a seven-page fact sheet that describes a system to catch, store, and reuse rainwater for irrigation in high tunnels. Approximately 900 gallons of water will flow from the roof of a 30' by 96' high tunnel during a half-inch rain event.


The fact sheet describes how to build a system to catch, store and reuse therainwater for irrigation in a high tunnel. The cost of installing rain gutters,rainwater storage tanks, and an electric pump is estimated at $1,200. Asolar-powered pumping system will add approximately $700 to that cost.
