• SNOWS project from 2009-2014 involves 1million pounds from Welcome Trust. KNUST is the leader of a consortium of 9 institutions seeking to build research capacity in water supply, environmental sanitation and environmental Health. This the consortium is to provide research management training for staff involved in research and provision of fellowships for PhD and Masters students to carry out research and build research capacity in water supply, sanitation and environmental Health. The consortium is carrying out needs assessment and organizing training for staff involved in research and provision of fellowships for PhD and Masters Students to carry out research. The Institutions are London School of Hygiene, University of Copenhagen, East Anglia, Tswane and Venda in South Africa, University of Edgerton in Kenya, Mbara in Uganda and KNUST in Ghana.
• SWITCH project from 2005-2010 involved 13million Euros project funded by European Commission and 33 partner Institutions from 15 countries. KNUST works with national and international partners including UNESCO-IHE. The aim was achieving more sustainable urban water management in the city of the future. They use innovative scientific, technological and socio-economic solutions, which can then be more speedily replicated around the world.  It has research across six themes and these are paradigm shift to sustainable and integrated urban water management, storm water management, efficient water supply and use for all, innovations in sanitation and waste management, urban water environments and planning and Governance and institutional change.
