Inadequate data management impedes progress in the Water, Sanitation, and Hygiene (WASH) sector. WASH professionals lack training in essential data management competencies, hindering effective data storage, organization, description, and sharing, in line with FAIR data principles. To address this gap, the openwashdata community will be established to support members. Open-source computational tools will be utilized and taught to enhance FAIR data competencies. Anticipate over 50 previously unreleased data sets contributed by community members. This will foster a network of WASH professionals committed to implementing FAIR data principles, benefiting the entire sector.
