Questions
Who issues water tenders most frequently?
Municipal water utilities, ministries of water and sanitation, river-basin authorities, and donor-funded PMUs under World Bank, AfDB and ADB projects.
Are WASH grants available to private companies?
Yes — innovation grants from Grand Challenges Canada, USAID DIV, and IFC TechEmerge support private-sector WASH solutions, though most grant flows still run through NGOs and government.
