Their core work

EYDAP is Greece's largest water utility, responsible for water supply and sewerage services across the Athens metropolitan area. In H2020 projects, they serve as a real-world demonstration site and operational partner for testing circular water technologies, resource recovery from wastewater, and smart water monitoring systems. Their value lies in providing access to large-scale urban water infrastructure — treatment plants, distribution networks, and catchment areas — where innovations can be validated under actual operating conditions. They also contribute domain expertise in urban water management, climate adaptation, and building energy integration.

What they specialise in

How they've shifted over time

EYDAP's early H2020 work (2016–2018) centered on physical resource recovery from wastewater — extracting phosphorus, bioplastics, cellulose, and energy from treatment plant processes, alongside water catchment monitoring. From 2019 onward, their focus shifted toward digital water management (FIWARE platforms), climate adaptation through nature-based solutions, and even building energy systems (BIPV). The trajectory shows a utility moving from "what can we extract from wastewater" to "how do we make the entire urban water-energy system smarter and climate-proof."

EYDAP is evolving from a traditional water utility toward a digitally-enabled, climate-adaptive urban infrastructure operator — making them increasingly relevant for smart city and urban resilience consortia.

How they like to work

EYDAP participates exclusively as a partner, never as coordinator — consistent with their role as an infrastructure provider and demonstration site rather than a research leader. They work in large consortia (130 unique partners across 6 projects), which means they are well-connected but not driving project design. For consortium builders, EYDAP brings operational credibility and access to one of Southern Europe's largest urban water systems, making them a high-value demonstration partner.

EYDAP has collaborated with 130 unique partners across 21 countries, giving them one of the broader networks for a utility company. Their partnerships span Western, Northern, and Southern Europe, reflecting the pan-European scope of the Innovation Action projects they join.

What sets them apart

EYDAP is one of the few large-scale urban water utilities in Southeast Europe actively participating in EU innovation projects, offering demonstration access to infrastructure serving over 4 million people. Unlike research institutes or technology SMEs, they bring the operational reality of a major utility — regulatory constraints, aging infrastructure, real wastewater streams — which is exactly what Innovation Actions need for credible large-scale demonstrations. Their cross-domain experience spanning water, energy, and digital systems makes them unusually versatile for a utility company.

Highlights from their portfolio

• IMPETUS
  Most recent project (2021–2025) focused on climate resilience and nature-based solutions, signaling EYDAP's strategic direction toward climate adaptation.
• PVadapt
  Largest single EC contribution (EUR 303K) and an unusual topic for a water utility — building-integrated photovoltaics — suggesting EYDAP is exploring energy self-sufficiency for its facilities.
• NextGen
  Core circular economy demonstration project covering water reuse, energy recovery, and materials recycling at scale — the most complete expression of EYDAP's circular water ambitions.
