Their core work

EYATH SA is the water supply and sewerage utility serving Thessaloniki, Greece's second-largest city. They operate drinking water treatment, distribution networks, and wastewater infrastructure for over a million people. In H2020, they contributed as an end-user and validation partner for water security technologies — testing sensor networks, contamination response systems, and satellite-based water quality monitoring in their real operational environment. Their value lies in providing a large-scale, real-world urban water infrastructure where research tools can be piloted and validated.

What they specialise in

How they've shifted over time

EYATH's H2020 involvement spans a short but coherent window (2019–2023), showing a clear progression. Their earliest project (aqua3S, 2019) focused on standardisation, sensor hardware integration, and citizen feedback mechanisms for water network security. By 2020–2021 (PathoCERT and WQeMS), the focus shifted toward pathogen-specific contamination response, public health implications, and remote sensing via Copernicus satellite data — moving from infrastructure-level monitoring toward more sophisticated, data-driven emergency response and environmental observation.

EYATH is moving from hardware-focused water network monitoring toward data-intensive approaches combining earth observation, pathogen modelling, and emergency response — expect future interest in digital twins and AI-driven water management.

How they like to work

EYATH participates exclusively as a consortium partner, never as coordinator — consistent with their role as an end-user utility providing real infrastructure for testing. With 52 unique partners across 16 countries in just 3 projects, they operate in large, diverse consortia (averaging 17+ partners per project). This makes them an accessible, experienced consortium member who understands multi-partner EU project dynamics and can offer operational validation sites without competing for project leadership.

Despite only 3 projects, EYATH has built connections with 52 partners across 16 countries, reflecting participation in large Security and Environment consortia. Their network spans broadly across Europe with no single dominant geographic cluster beyond Greece.

What sets them apart

EYATH operates one of Greece's largest urban water networks, which makes them a high-value validation partner — few utilities of this scale participate in EU research. They can offer real-world pilot sites for water security, contamination detection, and quality monitoring technologies in a major Mediterranean city. For consortium builders, they bring both infrastructure access and operational expertise that technology developers and research groups typically cannot provide themselves.

Highlights from their portfolio

• PathoCERT
  Largest EYATH project by funding (EUR 154,375), addressing the critical intersection of pathogen contamination, emergency response, and public health in water systems.
• WQeMS
  Represents EYATH's move into earth observation, combining Copernicus Sentinel-2 satellite data with in-situ monitoring for lake water quality emergencies.
