Maji Marwa: Rainwater Harvesting Initiative

This thesis documents an initiative to build capacity in the African community of Marwa, Tanzania, towards the goal of bringing accessible water to Marwa Village. Over three years of the research project, three rainwater harvesting systems were installed in Marwa utilizing a hybrid design of local construction techniques and other introduced innovations. The three tanks provide 91,000 L of storage capacity and over 350,000 L of water use potential. The cost of the rainwater harvesting system was reduced and the constructability increased through efforts of planning, communication and technical innovations.
