Crete’s Drinking Water Problem: Addressing Island’s Supply Challenges

Greece faces mounting challenges as water shortages plague several of its popular island destinations. The picturesque landscapes of Crete, the largest Greek island in the southern Aegean, are particularly affected by dwindling water supplies. This crisis extends beyond Crete to other regions, including parts of the Peloponnese like Messinia in the southwest and areas near Kythera in the southeast.

The situation has grown increasingly dire, with local authorities scrambling to implement conservation measures. Residents and tourists alike are grappling with the reality of limited water access, a stark contrast to the abundant sea surrounding these Mediterranean havens. As summer temperatures soar, the strain on water resources intensifies, highlighting the urgent need for sustainable water management strategies across Greece’s island communities.

Water Crisis in Crete: Dramatic Decrease in Water Reserves – Forecasts for the Future

Crete has experienced a severe water shortage this summer, with reservoirs and springs nearly depleted. The situation has become so dire that municipalities across the island have declared states of emergency due to the lack of water.

Eastern Crete faces the most acute challenges. The Aposelemis Dam, the largest on the island, is almost empty. Water levels in the springs of Chania have also dropped dramatically. The only glimmer of hope is the Amari Rivers Dam, which remains at 95% capacity.

The need for a change in consumer attitudes towards water usage has never been more pressing. Rational water use must become a priority for residents and visitors alike.

Aris Papadogiannis, director of the Crete Development Organisation, describes the situation in Chania as extremely difficult after two harsh hydrological winters. Rainfall has been far below expected levels for the past two years, leading to significant water scarcity issues.

Authorities are working together to develop plans and scenarios to avoid reaching critical levels that would necessitate water supply cuts. While Chania has not yet faced severe disruptions, a slight reduction in consumption combined with falling temperatures may help meet demand in the coming months.

The construction of new hydraulic and irrigation projects could provide some relief to the water crisis. However, officials stress that the danger has not passed, and continued vigilance and conservation efforts are crucial.

The crisis has sparked debates about the sustainability of the island’s water resources and the need for long-term solutions.

Water Crisis Prompts Emergency Declaration in Municipalties

The Municipality of Mylopotamos faces a severe water shortage crisis during the current summer season. This dire situation stems from the limited rainfall recorded in the previous winter period. The reduced precipitation has led to a significant decrease in the water table levels, resulting in limited output from boreholes and other local water sources.

The pressure on the water supply system has reached dangerous levels and continues to rise, while the demand for water for both domestic use and irrigation remains high, especially during the tourist season. Given these circumstances, the Municipality of Mylopotamos has decided to submit a request to declare the area in a state of civil protection emergency.

The primary objectives of this emergency declaration are:

1. To mobilise relevant authorities and agencies swiftly
2. To secure immediate support and resources
3. To implement urgent measures to address the water crisis

The municipality’s request includes specific proposals and actions to tackle the problem:

• Strengthening measures to protect water resources
• Fulfilling funding requests for water supply projects
• Upgrading and modernising outdated water supply networks prone to frequent leaks
• Drilling new boreholes and repairing existing ones to improve efficiency
• Educating consumers and promoting additional measures to safeguard water resources

By implementing these actions, the Municipality of Mylopotamos aims to ensure an uninterrupted water supply to meet the increased needs of the area and effectively manage the critical water shortage situation it faces.

To better understand the severity of the situation, let’s examine some key factors contributing to the water crisis:

1. Climate Conditions:

   • Unusually dry winter season
   • Reduced snowfall in mountainous areas
   • Higher than average temperatures

2. Water Infrastructure:

   • Ageing pipeline system
   • Insufficient water storage facilities
   • Limited water treatment capacity

3. Increased Demand:

   • Growing population
   • Expansion of agricultural activities
   • Rising tourist numbers during peak season

These factors have combined to create a perfect storm of water scarcity in the region. The local authorities are now faced with the challenge of balancing the needs of residents, farmers, and the tourism industry whilst conserving limited water resources.

To address this crisis, the municipality is considering implementing the following short-term measures:

1. Water Rationing: Introducing scheduled water cuts in certain areas to conserve resources.

2. Restrictions on Non-Essential Water Use: Banning activities such as car washing, filling swimming pools, and watering gardens during peak hours.

3. Leak Detection and Repair: Deploying teams to identify and fix leaks in the water distribution system quickly.

4. Public Awareness Campaigns: Educating residents and tourists about water conservation techniques and the importance of reducing consumption.

5. Emergency Water Deliveries: Arranging for water tankers to supply areas experiencing severe shortages.

In addition to these immediate actions, the municipality is also exploring long-term solutions to improve water security:

1. Desalination Plants: Investigating the feasibility of constructing small-scale desalination facilities to supplement freshwater sources.

2. Water Recycling: Developing systems to treat and reuse greywater for non-potable purposes such as irrigation and industrial processes.

3. Rainwater Harvesting: Encouraging the installation of rainwater collection systems in new buildings and retrofitting existing structures where possible.

4. Smart Water Management: Implementing advanced monitoring and control systems to optimise water distribution and reduce waste.

5. Drought-Resistant Agriculture: Promoting the adoption of water-efficient farming techniques and drought-tolerant crop varieties.

The municipality has also reached out to neighbouring regions and the national government for assistance. They are exploring the possibility of establishing temporary water transfer agreements to alleviate the immediate crisis.

To better illustrate the current water situation, here’s a comparison of water levels in key reservoirs:

These figures highlight the severity of the water shortage and underscore the urgent need for action.

The economic impact of the water crisis is another significant concern. The region’s agricultural sector, which relies heavily on irrigation, is particularly vulnerable. Farmers are reporting reduced crop yields and are being forced to make difficult decisions about which fields to prioritise for watering.

The tourism industry, a vital source of income for the area, is also feeling the effects. Hotels and restaurants are implementing water-saving measures, but there are concerns that prolonged shortages could damage the region’s reputation as a holiday destination.

Local businesses are being encouraged to develop water management plans and invest in water-efficient technologies. The municipality is considering offering incentives for companies that significantly reduce their water consumption.

Environmental organisations are closely monitoring the situation, particularly the impact on local ecosystems. There are concerns about the potential long-term effects on wildlife habitats, especially in wetland areas and along river systems.

As the crisis unfolds, the community’s response will be crucial. Residents are being urged to report water leaks promptly and to adopt water-saving habits in their daily lives. Schools are incorporating water conservation lessons into their curricula to educate the younger generation about the importance of responsible water use.

Greece Faces Mounting Water Challenges

Greece grapples with significant water supply issues, particularly on its islands and in coastal regions. The situation has become increasingly dire in recent years, with several factors contributing to the problem.

Many Greek islands are experiencing severe water shortages. On Naxos, water reserves have plummeted from 1.5 million cubic metres in early 2023 to a mere 180,000 cubic metres in 2024. This represents a dramatic decrease in available water resources. Meanwhile, water consumption on the island has risen by 28% compared to the previous year.

Santorini presents a stark example of the water crisis. In 2020, during the COVID-19 pandemic when tourism dropped significantly, water consumption was 929,000 cubic metres. By 2023, this figure had skyrocketed to 2.3 million cubic metres. The island’s population of about 15,000 residents swells with up to 17,000 daily visitors from cruise ships, putting immense pressure on water resources.

The water scarcity extends beyond the islands. In southeastern Laconia, on the Peloponnese peninsula, the situation is critical. Popular holiday destinations like Kyparissi are struggling to meet water demands. Normally home to around 400 people, the population swells by thousands during the summer months. Water yield from local springs has dropped dramatically, from 150-180 cubic metres per day last year to just 35-40 cubic metres per day in 2024.

Crete, Greece’s largest island, is also facing severe drought conditions. Even some hotels are experiencing water shortages, with reduced flow from taps. This contrasts sharply with other establishments that continue to fill swimming pools, causing tension and raising questions about water allocation.

Several factors contribute to Greece’s water challenges:

1. Reduced rainfall: The last year with good rainfall was 2019.
2. Increased tourism: More hotels, villas with pools, and rising visitor numbers strain water resources.
3. Agricultural demands: Farmers need water for crops and livestock, competing with tourism and residential use.
4. Ageing infrastructure: In some areas, outdated water systems contribute to losses and contamination.
5. Overexploitation of groundwater: Excessive well-drilling has led to saltwater intrusion in coastal aquifers.

To address these issues, Greek authorities and communities are exploring various solutions:

• Desalination plants: Naxos has implemented a facility producing 1,000 cubic metres of drinking water daily.
• Water use restrictions: Some areas have banned non-essential water use, such as beach showers.
• Infrastructure improvements: There’s a need to upgrade water distribution systems to reduce losses.
• Sustainable tourism practices: Encouraging water conservation among visitors and businesses.
• Agricultural adaptations: Promoting drought-resistant crops and efficient irrigation methods.

Greece Leads Global Drinking Water Consumption

Recent data from the German Federal Statistical Office reveals surprising insights into global drinking water usage. Greece tops the list of countries with the highest per capita consumption, significantly outpacing other nations.

The top 10 countries for annual drinking water consumption per person (in cubic meters) are:

1. Greece: 946.55
2. Turkey: 761.92
3. Estonia: 746.60
4. Mexico: 697.39
5. Costa Rica: 667.6
6. Australia: 631.39
7. Japan: 621.84
8. Spain: 621.80
9. Netherlands: 476.22
10. Slovenia: 441.5

For context, Germany’s consumption is 249.32 cubic meters per person annually.

This high consumption in Greece, coupled with reports of water scarcity for summer 2024, raises concerns. The disparity between water sent through pipelines and what actually reaches consumers suggests significant infrastructure issues, likely due to aging and damaged water systems.

Greece also faces severe groundwater stress. According to the World Resources Institute’s index, where 5 indicates extreme water stress, Greece scores 4.34. This places it fourth in Europe for groundwater scarcity risk, behind Cyprus (5.0), San Marino (4.45), and Belgium (4.41).

The combination of high consumption, infrastructure problems, and groundwater stress paints a concerning picture for Greece’s water situation. This is particularly critical for rural areas relying on well water, as depleted groundwater levels could lead to shortages.

These findings underscore the urgent need for water conservation measures and infrastructure improvements in Greece to ensure sustainable water management for the future.

Crete’s Drought Contingency Strategy

Heraklion, the largest city on Crete, faces significant water supply challenges. The Aposelemis Dam, a crucial water source, is operating at critically low levels. With only 4 million cubic metres of water remaining out of its 27 million cubic metre capacity, the reservoir can barely meet the city’s needs for the next two to three months.

The situation is dire. Heraklion’s water consumption has already been reduced from 1,200 cubic metres per hour last year to a mere 400 cubic metres per hour currently. If rainfall remains scarce, even this reduced supply may become unsustainable by next summer.

To address this looming crisis, the Municipal Water and Sewerage Company of Heraklion (DEYAH) is exploring several options:

1. New Boreholes

   • Three new drilling sites have been identified:
     • Giouchtas
     • Agios Myron
     • Malia

   These locations are strategically chosen to tap into underground water sources, though the Giouchtas site has been contentious due to disputes between local municipalities.

2. Desalination
   DEYAH is considering partnering with private entities to implement desalination techniques. This could significantly boost the daily water supply to Heraklion’s network.

3. Almyros River Utilisation
   The potential use of Almyros River water has been a topic of discussion for years. However, DEYAH lacks the current capacity to conduct necessary studies. Even with support from the regional government or national authorities, this project would likely take at least five years to complete.

4. Network Improvement
   A massive project to replace Heraklion’s water distribution network is underway. This initiative aims to reduce water loss and improve overall efficiency. The project is progressing well and is expected to be completed by 2025.

To test the city’s resilience, DEYAH will conduct a three-day water supply interruption from 8th to 11th September. This planned outage, due to maintenance work at the Aposelemis Dam, will serve as a stress test for the water system.

It’s worth noting that despite the ongoing challenges, Heraklion experienced fewer water supply issues this summer compared to previous years. This suggests that current management strategies have had some positive impact.

However, the long-term outlook remains concerning. The water level at Aposelemis Dam is alarmingly low, and without significant rainfall, the situation could become critical. The city’s water managers are working diligently to implement both short-term solutions and long-term strategies to ensure a stable water supply for Heraklion’s residents and businesses.

As climate change continues to affect weather patterns, Crete and other Mediterranean islands may need to adopt increasingly innovative approaches to water management. The steps being taken in Heraklion could serve as a model for other regions facing similar challenges.
