D5.4 gives a summary on the drivers, barriers and requirements for transferability and replicability of the 15 digital solutions developed within DWC. In particular, it assesses key operational (e.g. local challenges and management practices, etc.), organizational (e.g. local ICT governance and system interoperability) and technical conditions (e.g. type of network, precipitation pattern, etc.) for a successful implementation of the solution. The results can be used as a checklist for water utilities to assess the potential for local deployment of each digital solution.
