The General Directorate of ASKİ has started a comprehensive study to separate the wastewater mixed with the Dikmen, Hatip, Kepir and Kutugün Streams, which connect to the Ankara Stream, and the storm water lines. The teams, accompanied by professional divers, scanned open streams and rainwater box sections with a camera and detected leak connection and fault points one by one. Within the scope of the project, which will prevent pollution and odor in Ankara Stream, waste water connections were determined at 120 points and unlicensed subscriber channel connections were determined at 376 points.
Ankara Metropolitan Municipality and its subsidiary ASKİ, which cares about public health and environmental pollution, have signed a very important project.
The common problem of Yenimahalle, Keçiören, Etimesgut and Sincan districts in the capital; Pressing the button to prevent the pollution experienced in the Ankara Stream, where the foul odor has been rising for years, ASKİ General Directorate started to separate the wastewater (sewage) mixed with the Dikmen, Hatip, Kepir and Kutugün Streams connected to the brook, and the Yalı and Ergazi Collectors.
Providing information about the works, General Manager of ASKİ, Erdoğan Öztürk, stated that open streams and rainwater box sections are viewed with cameras, starting from the detectable discharge points, to the leak connection and fault points, accompanied by professional divers. Öztürk said that in addition to handheld cameras, robot and drone cameras were also used within the scope of the project.
MIXING POINTS DETECTED ONE BY ONE
Öztürk shared striking information about the "Separation Project by Determining the Mixing Points of Waste Water and Rainwater Lines" and said:
“Unfortunately, in some places, wastewater was either connected to storm water lines or directly discharged into stream beds. In order to eliminate this situation that pollutes the stream beds, we immediately went out to tender. Then, with professional divers, we thoroughly checked open creeks and rainwater box sections with fully equipped safety equipment. We took samples to determine the characteristics of the leaked connections or malfunctions found.”
Stating that on some routes, the deformation of the instantly blocked sewer lines in open streams and closed sections on some routes, kickbacks occur in the basements of some buildings during precipitation, Öztürk said, “In order to prevent this situation, the waste water connections were temporarily bypassed to the rainwater sections. However, it became permanent after that. With the cancellation of these wastewater connections, only rainwater lines will be discharged to open streams and rainwater box sections. This will reduce pollution and odor.”
THERE ARE WASTE WATER CONNECTIONS AT 120 POINTS
Öztürk, 24 in Dikmen Stream passing through Çankaya, 60 in Hatip Stream passing through Hasanoğlan, Mamak and Altındağ, 6 in Kepir Stream passing through Etimesgut, 13 in Kutugün Stream passing through Çankaya, Yalı in Keçiören He noted that they detected waste water connections at a total of 6 points, 11 in the Collector and 120 in the Ergazi Collector in Yenimahalle. Öztürk stated that there are 376 unlicensed subscriber channel connections involved in rainwater lines and stream beds, and that their transmission is ensured.
161 DRINKING WATER FAILURE ALSO REPAIRED
Öztürk also emphasized that with the study, they realized that the malfunctions in the drinking water network lines were not able to rise to the surface and mixed with the rain water lines, box-section collectors and open stream beds, and that they repaired a total of 161 drinking water malfunctions in this way. Öztürk said, “Within the scope of the Separation Project by Detecting the Mixing Points of Wastewater and Rainwater Lines, we performed 58 meters of box-section imaging and solved the deformation and obstructions that prevent fluidity in the section structure. We viewed the open creek section at 149 thousand 43 meters,” he said.
