Jack Schultz has returned from Iran and his mission to study that country’s 2,000-year-old water systems. Last month, the 80-year-old civil engineer boarded a plane to Iran in the hopes that studying the desert region’s methods of delivering water to cities and towns would help Santa Cruz weather droughts. His trip was made possible by the peace-seeking group Fellowship of Reconciliation, established in 1905. He returned home last Friday and is still trying to digest the things he saw and learned. He plans to share his new found knowledge with city water officials.
