Motivation
Water Sector

Technology+ Hydraulic Modeling 1.0 to 2.0 using
AI, IoT, big data …

+ Advances in IoT and Smart/Remotesensors+ Big data – heterogeneous sources+ Precision-based AI analytics+ Advanced sensing and modelling
technologies+ Semantic representation/ reasoning &Smart Data Models+ AI for BI processes- Fragmentation of the key actors,
tailor-made solutions- Lack of standardization (industrywide)- Challenging Data exchange &interoperability- Reluctant to adopt open-source
solutions- Missing global integrated P/C security
context- Small (economically) market size

WATERVERSE

To develop a Water Data Management Ecosystem (WDME) for making data
management practices and resources in the water sector accessible, affordable,secure, FAIR, and easy to use

The Project at a Glance
Water Data Management Ecosystem for Water
Data Spaces▪ HORIZON-CL4-2021-DATA-01-03—

Technologies for data management (AI, Dataand Robotics Partnership▪ Start Date: 01 October 2022
▪ End Date: 30 September 2025
▪ Total cost: € 5 253 964,65▪ EU contribution: € 4 510 509,90▪ 17 partners from 10 EU countries▪ 6 RTOs▪ 7 SMEs▪ 1 large industry▪ 3 NPOs

WDME Logical Architecture▪ Multi-layer architecture to▪ consider the entire data lifecycle (collect, harmonise,fuse, manage, process)▪ empower the interoperability and trustworthy data
sharing▪ assess FAIRness of data assets▪ ensure security and energy efficiency in water utilities
operations

Pilot Use Cases▪ NL Pilot: Prediction of water quality and its
impact in the treatment steps▪ DE Pilot: Digital Village Twin for flood protection
and territorial management▪ CY Pilot: Leveraging the potential of water
digital twin and water analytics tools▪ UK Pilot: Addressing the challenges ofCombined Sewer Overflow performance▪ ES Pilot: Management of the integral water cycleand open innovation▪ FI Pilot: Smart water tools and risk management

NL Pilot Use Cases▪ NL#UC1: Collection and harmonisation ofheterogenous data▪

NL#UC1.1: Collect & harmonize raw datasets into WDME.

▪

NL#UC1.2: Synthetic data generation▪ NL#UC2: Sharing of the collected after its
preparation•▪

NL#UC2.1: Newly acquired data to perform model
predictions for Cl concentrations.

▪

NL#UC2.2: Data validation and reconciliation

NL#UC3: Federation of external data to makeavailable to Water Utility teams▪

NL#UC3.1: Data visualisation▪

NL#UC3.2: External sharing of Cl model predictions

Location: Andijk, The Netherlands

The GREAT project aims to establish the Green Deal Data Space Foundation and its
Community of Practice which builds on both the European Green Deal and the EU’s
Strategy for Data.
WATERVERSE has been in contact with GREAT project since one year.
We organized a common session during last Data Week 2023: AI and Data Spaces for sustainable smart city – water andother key resources challenges▪ Measures towards the creation of a harmonised and federated ecosystem based on the data space, focusing on thewater sector and related data-driven ecosystems.

A workshop series on Water Data Space:▪From GREAT and WATERVERSE experience to future Water Data Spaces workshop will be held on 16th April, 9:00 –12:00 CEST
▪ Starting from GREAT requirements/specs, we will merge them with the WATERVERSE ones, thanks to the support of our key
communities.

▪ Other (two) workshops will follow to consolidate the results and include them into official reports.
