Ambuj Ranjan, a student at the Aga Khan Academy Mombasa, with a member of the Junju settlement in Kenya and his water filtration system.


“The community is thankful for his project and his efforts to the Junju community,” the letter said. “We found this project to be very interesting and wish (Ambuj) all the best.”

Collaborating with his brother and teachers, Ambuj said he hopes to further his research in order to provide sustainable, cost effective and portable versions of this filtration system to the people of Junju. His science teachers and mentors, Charles Gumba and Lucy Mwandawiro, said Ambuj emulates various Aga Khan Academies Learner Profiles, specifically that of a leader and steward.

“I think what is outstanding about Ambuj is the way that he has taken his learning and made it come alive by taking it back to the community,” Lucy said. “This project was just his own initiative – he’s not being assessed anywhere, which is amazing. I guided him to think through the filtration process, such as what kind of filter to use and where to get the water tested so it’s acceptable. I think for him, growing up as a person, he’s very passionate about society and wants to bring change, and he’s going out of his busy schedule to do so.”

In the meantime, Ambuj is tracking the progress of his project with the support of two residents from Junju, who have reported that the systems are being used regularly with proper care. Ambuj said the community has also been trained to harvest rainwater and have been informed about the importance of using water sanitation systems for day-to-day activities. While he is constantly receiving positive feedback about the filtration system, Ambuj said that tackling the issue of water sanitation is only the first step in addressing other problems concerning education, health and overall quality of life.
