Water-energy nexus strategies for sustainable clean water supply in African cities is increasing at a faster rate than population growth, while its availability is shrinking due to competing demands from economic activities, decline in water quality and climate change effects. This is often compounded by ageing infrastructure and lack of resources to maintain and/or expand existing infrastructure to meet the demand. Furthermore, the high electricity costs associated with bulk water treatment plants; makes access to clean water for urban dwellers, particularly in township communities too costly. This seminar focuses on a study which addresses the challenges encountered in accessing affordable clean water supply and sanitation in growing township communities, and explores the potential for renewable energy-driven decentralized water supply for sustainable development of townships in growing African Cities. In this work, we explored the feasibility of the use of biogas generated from municipal wastewater, in powering decentralized water treatment plants for the supply of clean drinking water to township communities.

The case studies for the project were Diepsloot Township (Johannesburg, South Africa) and Chambishi Township (Kitwe, Zambia) will be presented.
