With an increase in population comes an increase in waste; city planners for Addis Ababa must decide how to manage the growing volume of fecal sludge.

This case study details the process of managing fecal waste in a developing and expanding city. Currently, in Addis Ababa, more fecal sludge is being produced than can be safely treated, causing damage to the environment and public health. Dr. Eyasu Tewodros serves as a technical advisor and water/environment engineering expert for the city’s Master Plan committee. Eyasu is faced with a crossroads in his treatment recommendation: should he suggest that Addis Ababa follow in the more traditional “Western” treatment method of treating the city’s fecal waste at a central location, or should he recommend scaling the treatment down to a decentralized approach with a modular treatment plan targeting subsets of the city population? It is up to you to make a sustainable, responsible treatment recommendation on Addis Ababa’s fecal sludge management.
