This report contains the demonstration outcomes of 11 digital solutions under WP2. For each solution, it describes the demonstration site and challenges, the achievements in terms of performance and return on investment and the approach to assess and quantify the benefits via solution-specific key performance indicators (KPIs). Section 1 introduces the solutions and their targeted impacts. The following section 2 to 12 document the demonstration of the digital solutions (DSs). For each DS, the solution itself and demonstration are outlined, KPI definition is documented and return on experience is assessed. By M30, all DS were at the stage of approaching the end of the demonstration phase. KPI were defined, but not fully assessed, yet. The deliverable will be updated by M42. This deliverable is further part of the full “environment” of WP2 deliverables. The baseline for implementing and demonstrating the DS is detailed in D2.1 Implementation plan (M12), and technical specifications and expected benefits and recommendations for replication are given in D2.3 Technology report (final version in M36 as D2.4) This report is a draft version of the final report that will be delivered updated in M42. Following the external review, the executive summary has been added to reflect the consideration of the comments received. The final report (M42) will be enhanced following the reviewers’ comments by splitting solution-specific Return on Experience section into technological issues (developers’ perspective), financial/ economic benefits (CAPEX/OPEX) and end- users’ experience including more generalized return on experience to reflect on the added value of the DWC digital solutions for water infrastructure operators linking solution-specific KPIs to overall expected impact and project KPIs.

This report is a draft version of the final report that will be delivered updated in M42 (November 2022).
