Seawater pools: A sustainable solution to Greece’s island drought?
The Greek islands, renowned for their stunning landscapes and vibrant tourist season, are facing serious challenges due to ongoing drought conditions. In an effort to address this crisis and conserve vital water resources, hotels may soon begin filling their swimming pools with seawater. Proposed legislation is currently being discussed in parliament, aiming to facilitate the installation of pipelines to allow for this transition.
Deputy Minister of Tourism, Elena Rapti, emphasised the need for such measures to relieve pressure on dwindling freshwater supplies. The legislation seeks to remove existing legal barriers that hinder the use of seawater in hotel pools. This initiative is part of a broader strategy to ensure sustainable tourism in these popular vacation destinations while prioritising water conservation.
Concerns Regarding Seawater Pools in Greece
Opponents of the new legislation express concerns that it fails to establish adequate quality standards for the discharge of water back into the ocean. It is widely known that even pools using seawater require chemical treatments for disinfection. Critics highlight that the law does not guarantee that only treated pool water will enter the sea, leaving room for other pollutants, such as sewage, which hotels have historically discharged improperly.
Elias Nokas, the director of Water Resources in the South Aegean Region, emphasised the need for regulations to mandate the removal of chlorine from water before it is released back into the ocean. He also mentioned possible negative visual impacts, stating that the installation of water pipes along beaches could detract from the area’s aesthetic appeal.
Moreover, critics assert that the contribution of swimming pools to overall water scarcity is exaggerated. In popular areas with numerous pools, such as Paros and Mykonos, the water used by these pools accounts for no more than 6% of total water resources.
There are further concerns about the environmental implications. When pool water leaks into the surrounding ground or is drained, the elevated salt levels can pose risks to local ecosystems, affecting both vegetation and soil health. Additionally, the release of chlorinated saltwater can be detrimental to marine life due to residual chlorine and changes in salinity.
Greece Endures Severe Drought
Over the last two years, Greece has been experiencing serious drought conditions. This challenge has intensified during the tourist season, placing additional pressure on already limited water resources, especially on the Aegean islands that attract numerous visitors.
A recent analysis highlighted a significant decline in average yearly rainfall, which has dropped by roughly 12% from 1971 to 2020 compared to earlier decades. The situation is dire in the southern areas, particularly on the Aegean islands and Crete, where rainfall has diminished by one-fifth. This water scarcity serves as a crucial warning, emphasising the need for sustainable management of Greece’s vital water resources.
Frequently Asked Questions
How do drought conditions impact pools on Greek islands?
Drought periods can lead to lower water levels and increased salinity in pools. As freshwater becomes scarce, these pools may suffer from reduced quality and usability, affecting both tourists and local communities. Maintaining the balance of salinity is essential for the pools’ proper functioning.
What initiatives are being adopted by Greek island communities to combat water shortages affecting seawater pools?
Local communities are implementing various strategies to manage water resources. This includes rethinking the legal frameworks surrounding water usage and promoting water conservation practices. In addition, some islands explore innovative solutions like recycling water and optimising the management of existing freshwater supplies.
What cultural importance do pools hold in Greek island heritage amidst environmental challenges?
Pools are deeply rooted in the history and culture of Greek islands. They have served as social gathering places and recreational spots for centuries. Despite modern environmental challenges, these pools continue to be symbolic of island life, reflecting the cultural heritage and resilience of local communities.
What part does desalination play in providing water to pools on Greek islands during droughts?
Desalination becomes a critical resource during droughts, as it allows the conversion of seawater into freshwater. This technology can help alleviate water shortages for both drinking and pool usage. By using desalinated water, islands can better maintain their seawater pools, ensuring they remain a viable feature for tourism and local enjoyment.
