EYDAP's program to install about 2.1 million smart water meters, at an estimated cost of about €300 million, is now targeted for tender in the first half of 2027. The date has slipped from 2023 to 2024, then to the end of 2026.
The control systems are moving first
While the meters wait, the Athens utility is building the systems that would use their data. In the first half of 2026 it completed a unified wireless metering platform, restructured metering routes for 651,126 services and put 53 online residual chlorine monitors into operation. Over the same six months, sewerage pumping stations were being integrated into a new SCADA system, a digital twin was being built at the Metamorfosi plant and a new SAP S/4HANA ERP was being implemented.
The losses goal
EYDAP's FY2025 annual report sets a strategic goal of reducing losses to 8–9% by 2029. Its non-revenue water was 23.70% in 2023 and 25.46% in the first half of 2026. Mains replacement ran at about 98 km in 2025 and about 38 km in the first half of 2026, on a water network of approximately 14,300 km.
Funding on hand
EYDAP reported no loan obligations at the end of 2025. It also has a €250 million European Investment Bank credit line, signed on July 25, 2025, with no drawdown reported. Its 2026–2035 investment plan allocates €145 million to buildings, digital governance, transformation and strategy, a line that absorbed €2.2 million in 2025 and €0.4 million in the first half of 2026.
How the 8–9% goal compares with EYDAP's other loss measures, where the €2.5 billion plan for 2026–2035 puts its money, and what the absorption of about 43 providers by July 31, 2027 means for its systems are set out in the report.
