Paul Berg is a registered professional engineer who has worked at Jacobs Engineering Group (formerly, CH2M Hill), a major international engineering consulting firm, for more than 30 years on drinking water supply and treatment projects. His work has taken him to Sri Lanka, Ghana, Liberia, Columbia, Paraguay, and many other locations around the world to assist with urban, village, and point-of-use water treatment issues. As a volunteer, he has evaluated drinking water needs and designed solutions for hospitals, villages, and schools in Uganda, Kenya, Ethiopia, Burundi, Nicaragua, and other developing countries. Paul obtained his bachelor’s and master’s degrees in civil engineering from Oregon State University. He was awarded the President’s Volunteer Service Award, President’s Council on Service and Civic Participation, by President Barak Obama, August 2010.

David Conklin is a climate change researcher with degrees in math, computer science, and a late-career Ph.D. in Biological and Ecological Engineering. In 2001, after a long career working with computers in Fortune 500 companies and his own small companies, he joined a team of global change scientists at the U.S. Forest Service and Oregon State University. In that job and subsequent roles, for the last two decades he has been developing and running models of climate change impacts on natural vegetation and river systems. In 2015 he started Oregon Freshwater Simulations, Inc., a small private company, to continue the modeling work.

As Christopher M. Smith retires, he reflects on the many years of helping others. Gifted with an ability to figure out how most things work and being able to know when to fix or toss, the “Mr.Fix-it” engineer draws on his life-long curiosity and compassion to be part of this Water Box project.


Chris started in 1992 working on concepts and designs with Paul Berg on a UVc water disinfecting systems suitable for use in developing countries. This current Water Box is heavily based on much of that work and the iterative efforts thereafter. 


He finds the greatest satisfaction in his work when a challenging project matches his creative design abilities, especially when that need serves a humanitarian purpose.


After working at Battelle as a senior mechanical engineer for 11 years, Christopher worked with Dr. Lewis Zirkle at SIGN Fracture Care International, developing a surgical targeting system for bone-fracture repair in the developing world. He moved into engineering consulting and opened Intellegration, a company for developing innovative solutions to real-world problems.


As the owner of Intellegration in Richland, Washington, he has supported work at the Hanford site and at other local companies like Lamb Weston, Iso-Ray, Inc., and Cadwell Labs. He was part of a team at IsoRay that received an R&D 100 award for an innovative laser-welding system to hold and weld rice-grain-sized, titanium-encapsulated radioactive seeds for prostate cancer treatment. He also holds patents for a robotic hand design and for food processing equipment.


In addition to his professional work, Christopher is deeply involved in humanitarian work. For 27 years, he has been active in Tri-County Partners, the local Habitat for Humanity affiliate, serving as chair of the Building Committee, treasurer, board member and board president. He has also traveled to Africa and Central American, volunteering with building water and sanitation systems. He is active in the Richland Rotary Club.

David Roth has spent many years in public service in Oregon. He worked for the Oregon Bureau of Labor and Industries (BOLI) for more than two decades in the computer systems department. He also founded a public affairs magazine named Oregon’s Future which lasted for several years. After retiring from the State in 2009, he worked for ten years with a volunteer lobbying group called Tax Fairness Oregon that lobbied the Oregon Legislature for progressive tax policy.
David received his BA in Architecture from UC Berkeley in 1980. He has worked for many years doing repair of residential properties, usually related to structure maintenance including electrical, plumbing and mechanical repairs. He spent many years volunteering with NASA and SETI setting up video viewing and counting systems for airborne meteor observations for the Leonid, Quadrantid, and Aurigid meteor showers, and guided an airborne spectrograph to observe the destructive re-entry of ATV-1 Jules Verne. He did volunteer work for the CAMS Project, a NASA funded meteor orbit surveillance system, and is currently writing analytical software for the meteor orbit data, for use by amateur meteor researchers.
