The Denizli Hotel and Business Owners Association (DENTUROD), which issued a warning regarding Pamukkale, has released a written statement. Calling on all authorities to take action on the matter, DENTUROD's statement is as follows:
URGENT CALL TO ACTION
WE MUST PROTECT PAMUKKALE
Pamukkale Hierapolis, a unique natural formation known for its travertine terraces, is listed as a UNESCO World Heritage site. These terraces have been formed over thousands of years by calcium carbonate deposits from mineral-rich thermal waters. However, the sustainability of this natural wonder is at great risk due to a significant decrease in water flow in recent years.
According to thermal water flow measurement data by the State Hydraulic Works (DSI), the total flow rate of thermal water resources in the Pamukkale Geothermal System was 450 liters per second in 1993, but this figure has dropped to 150 liters per second today. A decrease of 300 liters per second over 30 years poses a GREAT RISK to Pamukkale’s sustainability. The reduction in thermal water flow has resulted in the shrinking of the white travertine deposition areas. Therefore, it is imperative to investigate the changes in the pressure and flow rate of thermal water and develop and implement urgent research projects to protect the Pamukkale Geothermal System.
Main causes of the decrease in Pamukkale’s water resources:
Uncontrolled Excessive Water Use: Increasing water demand for agriculture and residential areas, and the proliferation of geothermal energy production facilities, lead to a decrease in water resources.
Climate Change: Global warming and irregular rainfall patterns cause groundwater levels to drop.
Inadequate Infrastructure: Water management infrastructure deficiencies in the region and lack of reinjection hinder the efficient use of water resources.
Proposed solutions:
Sustainable Water Management: Monitor and examine the flow rate, pressure, and chemical composition of waters from thermal drillings in the Karahayıt geothermal area and licensed and illegal drilling wells in Pamukkale Plain. Ensure efficient use and conservation of water in agricultural and residential areas.
Closure of Illegal Wells: All illegal drillings in Pamukkale, Akköy, and Karahayıt areas should be closed. The use of thermal water must be continuously monitored to prevent illegal usage.
Regulation of Geothermal Energy Production: Geothermal energy companies near Pamukkale must use appropriate technologies and management strategies to avoid harming water resources. Projects should be closely monitored with strict inspections to prevent water level drops and resource depletion.
Raising Awareness: Local residents and visitors should be educated about water conservation and the importance of protecting Pamukkale.
Infrastructure Renewal: Urgent renewal of water management infrastructure, especially in the Karahayıt region, is necessary.
Establishment of a Research Institute: A Pamukkale Geothermal System research and monitoring institute should be established under Pamukkale University, employing expert and competent researchers.
The protection and sustainability of Pamukkale can only be ensured by taking necessary measures. Without these efforts, the water flow in Pamukkale will continue to decrease due to global and climate change impacts, and the white travertine areas will significantly shrink over time.
We call upon all relevant ministries, the governorate, local administrations, members of parliament, all individuals living in and who love Denizli, and civil society organizations in Denizli to take responsibility.
The preservation of Pamukkale for future generations is possible through the protection and efficient use of its water resources.
We invite all relevant institutions, organizations, and individuals to take ownership of Pamukkale.
