Manual handpumps are the primary source of water for millions of people worldwide, including at Ongariama School in Busia, Kenya. But such sources can suffer from microbial contamination.
Kennedy Brown, a civil and environmental engineering PhD student doing the DevEng designated emphasis, was in Busia in June to adapt the TuriTap, an in-line chloronation device developed by DevEng Prof. Amy Pickering and colleagues, to manual handpumps like the one at Ongariama School. The above photo, showing her working on the installation alongside her Mangrove Water colleague Titus Odipo, has taken home first prize at this year’s DevEng Photo Contest.
The TuriTap treats drinking water by accurately dosing liquid chlorine into the supply without requiring any electricity.
“In line chlorination is an efficient, low-cost water treatment method for low- and middle-income countries which provides instant and residual disinfection at the point of collection,” writes Brown, a member of Pickering’s lab. Sans the TuriTap, “there are no viable in line chlorination technologies compatible with manual handpumps.”

The University of the Philippines Resilience Institute tasked Noam Anglo, MDevEng ’26, and a colleague with developing a prototype for an earthquake shaking table to support the institute’s earthquake-resilience education projects.
Anglo and Sir Christian (left) walked across the street to the university’s mechanical engineering machine shop to learn from Sir Paul (center) how to make their designs manufacturable. This second photo, showing the three engineers at work, took home second prize in the 2026 DevEng Photo Contest.
“I learned engineering speaking English, but we were mostly speaking Filipino; it turns out that the language of engineering is universal,” Anglo wrote. “Despite having flown an ocean away, I again found myself talking shop with world-class engineers, just like anywhere else.”
