Surface Moisture Improves but Persistent Deep Drought Threatens Crete’s Agriculture. Heraklion faces a severe water crisis due to ageing infrastructure and persistent drought, and the plan for the city’s future water supply.
Despite recent early December rains bringing relief to the surface soil of Crete, a persistent drought continues to grip the island at deeper levels, posing significant risks to agriculture and water resources.
According to the latest analysis by the METEO team of the National Observatory of Athens, while surface soil moisture (7–28 cm depth) has shown noticeable improvement following the early December storms, the deeper soil layers (28–100 cm) remain critically dry across much of Crete. This deeper drought reflects the cumulative water deficit from previous months, which has yet to be replenished.
This contrast between surface recovery and deep soil dryness is concerning because the moisture content at these depths is crucial for sustaining crops over longer periods. The prolonged water stress threatens the health and yield of many agricultural plants, which rely on these underground reserves during dry spells.
The team’s assessment, based on data from the European Union’s Copernicus service, uses a standardized soil moisture index comparing current conditions to the 1991-2020 reference period. Crete’s deep soil layers currently exhibit mild to severe drought levels, maintaining a high risk of water stress for farmers and local ecosystems.
While the recent rains helped boost surface moisture, the overall water deficit underscores the challenges Crete faces amid ongoing climate variability. Sustainable water management and irrigation strategies will be essential to mitigate the impact on agriculture and preserve the island’s vital water resources.

Heraklion Faces Serious Water Crisis Amidst Aging Infrastructure and Prolonged Drought
Heraklion, the vibrant capital of Crete, is currently grappling with a severe water supply crisis that threatens daily life and the city’s future sustainability. The combination of prolonged drought, repeated infrastructure failures, and outdated water pipelines has pushed the city’s water system to its limits.
Since early December, the city’s main water source—the Aposelemis dam—has been offline due to ongoing maintenance and technical issues. Originally expected to resume operation quickly, repairs have now been extended by at least five more days, exacerbating shortages. Meanwhile, a critical pipeline failure in the Malia area has caused widespread disruptions, affecting at least ten neighborhoods, including the city center.
The root of these problems goes beyond temporary setbacks. The water supply infrastructure in Heraklion is aging rapidly: the main pipelines were constructed decades ago, with the Malia pipeline dating back to 1961 and the Tylisos pipeline to 1970. These aging conduits frequently suffer breakdowns, making water delivery unreliable and straining the entire distribution system.
Adding to the crisis is an extended period of low rainfall, which has depleted reservoirs and limited the capacity to replenish water supplies. Experts warn that without urgent upgrades and sustainable water management practices, Heraklion’s water challenges will only worsen.
The city’s water utility company, DEYAH, is working to restore service gradually, but residents are urged to conserve water and prepare for intermittent supply interruptions in the coming days.
Heraklion’s water crisis highlights the urgent need for investment in modern infrastructure and long-term solutions to secure water availability for residents and businesses alike. As climate change intensifies drought risks, proactive measures are essential to safeguard the city’s future.
Ambitious Plan Unveiled to Secure Heraklion’s Water Supply with New Dam and Desalination Unit
Heraklion, Crete’s bustling capital, is set to benefit from a comprehensive new water supply plan aimed at solving its longstanding water management challenges. The Organization for the Development of Crete (OAK) has proposed a bold project combining the construction of a large dam at Gioufyros and a supportive desalination plant at Almyros to ensure a reliable, long-term water source for the city and surrounding northern coastal areas.
The new dam’s catchment area at Gioufyros is expected to hold nearly twice the water volume of the existing Aposelemis dam, which currently serves much of Heraklion. This expansion will not only increase water availability but also provide crucial flood protection for the wider region.
Alongside the dam, the desalination unit at Almyros will serve as a vital backup source, especially during dry periods, helping to stabilize supply and reduce dependence on rainfall. Together, these infrastructures aim to create a resilient, integrated water system capable of meeting the needs of Heraklion’s growing population.
The total estimated cost for the project, including pipelines and treatment facilities, is approximately €65 million. OAK emphasizes the importance of unified water management across Crete to optimize resource use and coordinate future investments effectively. Currently, the island’s water sector is fragmented, with 76 providers managing nearly 520 water supply and irrigation systems, limiting efficient planning.
This ambitious plan represents a significant step forward in addressing Heraklion’s water scarcity issues and enhancing the sustainability of water resources on the island. With government support and coordinated management, the project promises a brighter, wetter future for Crete’s largest urban center.
