A new device for low-cost monitoring of combined sewer overflows is being deployed in large sewer networks. Data obtained will support the digitalisation of urban water systems and improve the knowledge of utilities regarding the performance of sewer networks during rainfall events. This device is only one out-of-15 innovative technologies tested within the H2020 digital-water.city innovation project., In publication process This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 820954.

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).

This chapter provides a review of the models available for estimating the production and emission of methane from wastewater collection and treatment systems. The details of a number of mechanistic models as well as the simplified empirical models have been summarized. Their limitations have been identified and general methods for calibration and validation have been presented.

The Implementation Plan (D2.1) is a document, which outlines how and where different digital solutions for water infrastructures will be demonstrated and assessed in the scope of WP2 of the DWC project. It is the first of three deliverables and followed by demonstration and assessment of performance and return of investment by means of key performance indicators (KPI) also defined in this deliverable., Version (v0.1.0) submitted to EC.

El projecte consisteix en obtenir les dades d'un Kinect, tractar-les amb el SDK Kinect FaceTracking per obtenir les expressions facials i la inclinació del cap d'una persona que aparegui a la imatge, per finalment animar un avatar 3D amb aquestes dades This project involves obtaining data from a Kinect, treat them with FaceTracking Kinect SDK to obtain facial expressions and head tilt of a person who appears in the picture, finally animate a 3D avatar with these data.

Combined sewer overflows (CSOs) are of major environmental concern for impacted surface waterbodies. In the last decades, major storm events have become increasingly regular in some areas, and meteorological scenarios predict a further rise in their frequency. Consequently, control and treatment of CSOs with respect to best practice examples, innovative treatment solutions and management of sewer systems is an inevitable necessity. As a result, the number of publications concerning quality, quantity and type of treatments has recently increased. This review therefore aims to provide a critical overview on the effects, control and treatment of CSOs in terms of impact on the environment and public health, strict measures addressed by regulations, and the various treatment alternatives including natural and compact treatments. Drawing together the previous studies, an innovative treatment and control guideline is also proposed for the better management practices., The authors acknowledge the European Union's Horizon2020 research and innovation programme for co-funding INTCATCH innovation action under grant agreement No.689341.
