This research collection includes reports, case studies, evaluations, and fact sheets on water, sanitation, and hygiene. This database is not intended to be exhaustive -- other online resources, such as the'IRC WASH library, already serve that function. Rather, this collection represents a curated set of readings recommended by experts in the sector as especially important and informative. New research will be added to the database as it is published and/or suggested by site users. Search the collection using the boxes below and see what the experts are reading.
