Despite recognition of its importance, reliable methods for pathways for achieving universal access to safe and affordable drinking water and sanitation are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
