Lake Küçükçekmece in western Istanbul has turned brown after sewage mixed into the channels that feed the lake. According to Cumhuriyet, the wastewater flowing into the lake has completely altered its color and appearance, creating a disturbing scene along the shoreline.
Lake Küçükçekmece is not only one of Istanbul's important wetland areas but also home to an ecosystem that directly affects the quality of life of the densely populated surrounding communities. The intrusion of wastewater has reignited concerns over water pollution and inadequate infrastructure.
Neither Istanbul Metropolitan Municipality nor the relevant water and sewerage authority has issued an official statement in response to the report. Cumhuriyet, which documented the contamination with footage and images, called for an investigation into its source.
Küçükçekmece Lake has been polluted with sewage water, turning the lake brown. The mixing of wastewater with the lake, one of Istanbul's important water basins, has exposed infrastructure deficiencies. Official institutions have not yet issued a statement.
The pollution of the lake means that the dense population in the surrounding area is facing water quality and health risks. The failure of wastewater management is increasing the likelihood of flooding and additional infrastructure problems in Istanbul.
