Stergiou (EYDAP): Attica’s water reserves are sufficient for one year

A difficult hydrological year for Greece

The year 2025 is shaping up to be one of the most challenging hydrological years Greece has faced in decades. Prolonged dry spells and unusually high temperatures have caused a significant drop in water reservoir levels across the country. Despite these conditions, the Attica region, which includes the capital Athens, remains — at least for now — in a secure position.

Speaking to Parapolitika 90.1 FM and journalist Niki Lymberaki, EYDAP President Giorgos Stergiou said:“Current water reserves in Attica are sufficient for one year — even if not a single drop of rain falls during that time.”

Reservoirs held up — thanks to early intervention

Mr. Stergiou emphasized that the Mornos, Yliki, and Evinos reservoirs had seen declining levels throughout 2024, but early activation of backup wells and the use of underground water reserves helped stabilize the situation.“The measures of the past 18 months are showing results. For the first time in years, we’re working with prevention — not just crisis management,” he said.

He also highlighted that government coordination between the ministries of Environment, Infrastructure, and Climate Crisis was “much faster than in previous drought periods.”

The Kremasta project – a long-term safeguard

A key component of EYDAP’s long-term strategy is the Kremasta Project, which aims to secure water supply stability for the greater Athens area for decades to come.“This is a long-term solution that will ensure stable water supply for many years ahead,” said Stergiou, noting that the networks connecting Mornos, Evinos, and Yliki remain the vital arteries of Attica’s water system.

Desalination: a last-resort measure

Addressing the prospect of desalinated water, Stergiou clarified that EYDAP views it as a “last-resort option.”“Desalination will only move forward if climate conditions worsen dramatically and all other alternatives are exhausted. For now, our focus remains on sustainable use of existing resources,” he explained.

Nonetheless, EYDAP has already begun feasibility studies and pilot initiatives in areas where desalination could play a supporting role — such as the Saronic Gulf islands.
