One of the challenges in the implementation of Water Safety Plans (WSPs) is stakeholder engagement. For this reason, IHE Delft Institute for Water Education has developed a role-playing game for practising stakeholder collaboration in WSP. The game can be used in WSP training or during educational activities for water safety and WSP at graduate and post-graduate level. Its goal is for participants to experience the importance of stakeholder engagement in WSPs, and particularly in the decision-making process when investing in the rehabilitation and maintenance of a drinking water supply system from catchment to consumers. Participants will experience how this process can be influenced by information exchange between stakeholders and how this will eventually lead to greater awareness when assembling the WSP team.
