Sustainable freshwater supply in Maputo, Mozambique

subsidie fonds duurzaam water

Water reuse offers great potential for reducing water shortages. However, suitable technologies and approaches lack for sustainable reuse in the social setting of in development countries. The overall objective is to reduce water shortages in Maputo by enabling the local water sector to include water reuse in overall planning and design of the urban water system.

Knowledge gaps exist on integrated technical and social aspects of productive use of waste water in development countries. Little research has been published in this field. The research challenge is to obtain integrated social and technological knowledge to assess and predict effectiveness and sustainability of integrated water reuse strategies.

To achieve this the research will focus on understanding centralized and decentralized water reuse systems from a technological and social perspective. The reuse of centralised wastewater will be studied at the wastewater treatment plant in the Infulene valley (the only large scale treatment plant in Maputo). The goal is to turn this treatment plant into a profitable “mine” that produces clean water for irrigation and industry, energy by digestion of concentrated waste streams and sludge, and nutrients for agriculture.  The reuse of decentralised wastewater will be studied in peri-urban areas, assessing and pilot testing the potential of reuse.

The two research projects will lead to reliable tools / models for local stakeholders who need water reuse strategies. Within each research project mixed teams of social science and water management PhD researchers will collaborate, institutionalising optimal multidisciplinary collaboration.
