Dr. Luiza Campos, AfriWatSan co-Investigator from UCL, visited Université Cheikh Anta Diop (UCAD) Dakar (Senegal) from 6th to 10th March, 2017. Her visit sought to: (1) identify potential areas of collaborative research on urban, low-cost sanitation provision; (2) understand the sanitation service supply chain and its relation to groundwater resources and public health in Dakar;(3) review equipment needs; and (4) advise on research activities related to sanitation aspects including on-going PhD research under AfriWatSan.

Dr. Campos meets UCAD AfriWatSan Team, visits Laboratory of Wastewater Treatment (LATEU), and together with Dr Seydou Niang, runs a seminar with UCAD post-graduate students.
