My name is Sam Watson and I graduated from Charlton School in the Class of 2013. After studying for my A-Levels at what was New College in Wellington, I went to the University of Cambridge to study Chemical Engineering. Through the Chemical Engineering Department at university, I found out about the Cambridge Development Initiative (CDI).
As of this year, I have begun volunteering with CDI and am heading out to Tanzania this summer for two months (Aug/Sept) to take part in working with local communities in Dar es Salaam (Tanzania's largest city) to help tackle significant problems in hygiene and sanitation. 

CDI is a non-profit organization that improves the wellbeing of community members in the schools, informal settlements, and wider communities of Dar es Salaam, Tanzania. CDI empowers student leaders in the United Kingdom and Tanzania to catalyse change in their societies through innovative projects in the areas of healthcare, education, entrepreneurship, and water, sanitation, and hygiene (WaSH).

The CDI WaSH project provides a sustainable, community-centred solution to the sanitation crisis in Tanzania. Operating in Dar es Salaam’s informal settlements where residents lack access to proper sanitation, the WaSH project prevents water-borne illnesses by building safe simplified sewerage systems. CDI and KITE collaborate with the Dar es Salaam Water and Sewerage Authority to manage and execute this initiative. To promote this initiative’s economic and environment sustainability, the WaSH team aims to offer biogas as a renewable alternative to charcoal. Since 2015, CDI has been testing biodigestor technology, which turns waste collected by our sewerage networks into biogas.

CDI intends to ensure the continued benefits of our project by transitioning from their current biodigestor model to one that is locally sourced through a Tanzanian supplier. This shift will enable community members to efficiently undertake repairs while creating a social enterprise through which biogas sales will fund the construction of new sewerage networks. To accomplish this goal, they need to raise about £2,000 for this local model.
