The Bill & Melinda Gates Foundation calls for solutions to make it easier to access safe, clean water and sanitation services for the urban poor in low- and middle-income countries. The Foundation seeks solutions that target individuals, families, communities, urban planners, service providers, or WASH/ food infrastructure, networks, and systems. Selected early-stage projects will receive US$100 thousand and have one opportunity to apply for a follow-on award of up to US$1 million. Eligibility extends to non-profit organizations, companies, government agencies, and academic institutions. The application deadline is 14 November 2018. More about WASH in Urban Settings
