Susan Murcott is a water/wastewater engineer whose career has had a triple focus. The first focus is wastewater innovations in mega-cities, with projects in Mexico City, Sao Paulo, Beijing and several cities in Central and Eastern Europe. The second focus is small-scale drinking water systems for “the bottom billion,” those who lack improved water, whose piped supply is at risk or who need safe water in emergency settings. The third, most recent, focus is the evaluation of technologies for the poor. She is a Research Scientist in the MIT’s Department of Urban Studies and Planning and the Senior Technical Lead of the Water Filter Evaluation for the MIT/US Global Development Lab’s Comprehensive Initiative for Technology Evaluation (CITE). Her work is dedicated to raising awareness of and making a contribution towards providing safe water, sanitation, hygiene (WASH) and environmental well-being for all. Murcott has worked on water/wastewater projects in over 25 countries spanning all continents. The non-profit organization she co-founded, Pure Home Water, has built and currently operates a water filter factory in Northern Ghana which is staffed by trained local Ghanaians.
