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.
While Schultz did not get to see Iran's water systems, he did get to meet with water engineers.
"They have water supply shortages looming in their country just like here," he said.
When asked why that is, he replied population growth.
"It's not growing fast, but it is growing," he said.
Encouraged by the people he met, Schultz is trying to raise funds to return to Iran in the hopes of finishing what he started -- studying the country's ancient water systems.
He estimates he spent $6,000 on his recent two-week trip.
"And I borrowed that," he said.
But while he's back in town, Schultz not only plans to share stories about Iranian water delivery system, but also of their desire for peace.
"The standard conversation with everyone we talked to on the street was about peace, avoiding war, defending themselves when attacked and how to get a visa to America," Schultz said.
Schultz is not stranger to traveling and problem-solving.
He lent his services to the American Red Cross after Hurricane Katrina devastated the Gulf Coast. He also lent a hand to help rebuild water supplies on the west coast of Sumatra after a massive tsunami.
Schultz, who has lived in Santa Cruz for 25 years, also has quite an adventure bug.
At 18, he took a solo canoe ride down the Amazon. The Miami native has also been featured in National Geographic.
