43669

Marmara Basin covers 2.96% of area of Turkey with approximately 23 084,6 km2 area. The basin covers entire catchment area of the all rivers that flows to Marmara Sea except Susurluk River. Significant increase in population growt and urbanizaton process in the basin has important effect on water quality just like other environmental problems. In the basin, effect of household waste water on water quality is depend on distribution of population and existence of treatment plant. Household waste water and industrial waste water amounts in especialy İstanbul and Kocaeli province are always higher because of accumulation of population, urbanization and industrializaton on eastward in the basin. Thus, across the basin, İstanbul province comes first and Kocaeli province follows it according to contaminated and under risk of contamination surface water resources. And also rivers of Yalova, Çanakkale and Tekirdağ provinces located in the basin are contaminated. Other domains of wastewater are, coastal areas of İstanbul province, Gulf of İzmit and Gulf of Gemlik. Municipalities that provides treatment service in İstanbul, Kocaeli and Bursa provinces that located in the basin, especially places located scope of metropolitan municipalities, has higher values than average of Turkey. This situation the basin s wastewater discharge environment has begun to have positive effect on water quality.
