Hubs are the visible face of the Danube Learning Partnership (D-LeaP) for active participants, as they have the primary capacity building delivery responsibility. Hubs are primarily established by national water utility associations and well-performing utility companies, but can also be professional associations or academic institutions. Each Hub offers one or several programs and serves a particular country or group of countries (with similar languages). Hubs are accredited by the D-LeaP Committee Council, before they can start delivering D-LeaP programs. Each Hub has (a) trainer(s) for a specific program, who was trained by a Technical Partner.
