The vision for SWIFt-MC is to develop and use advanced engineering analysis, technologies, models, and solutions to re-engineer water and sanitation/wastewater systems in underserved areas—both those lacking sufficient infrastructure and those lacking the resources to maintain existing infrastructure. This proposed planning grant will enable us to: (1) develop the SWIFt team though collaborative design workshops, meetings, and discussions, and build on the convergent research “DNA” of the team, and (2) finalize the concepts (research as well as inclusion, workforce development, education), strategies, team composition, advisory boards, testbeds, and partner communities, in preparation for preliminary proposal writing.
