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.
You will work through this case study in 3 parts. Part 1 will introduce you to the public health challenges that exist in Addis Ababa due to problems with waste management. Part 2 will detail Dr. Eyasu Tewodros’ findings as he travels the city and examines the existing waste management systems and facilities. Part 3 concludes the case by discussing the big picture health impacts of inadequate waste management, and orients you towards thinking about potential improvements to the city’s waste management system.
