Plumbers Without Borders envision a world where plumbers and mechanical tradespersons can easily offer their volunteer services to organizations working to improve global health and reduce the suffering and disease caused by water and sanitation poverty. We are developing a global database/directory of volunteer Plumbing and Mechanical tradespeople, related professionals, sources for materials, education, and technology. This databank will serve as a resource registry for both the humanitarian organizations, and the many willing plumbers, impassioned to serve, pro-bono, to share their expertise toward the greater collective mission.
