6.7- Municipal Water Supply
Indicator represents the pressure on water resources. Reservoirs are the most important and widely used water supply for the municipalities. In years of low precipitation, water drawn from the reservoirs may decrease while exploitation from rivers, lakes or ponds increases. In Turkey, total amount of water abstracted to water supply networks, 44.8% was abstracted from reservoirs, 26.8% from wells, 17.1% from springs, 9.5% from rivers and 1.8% from lakes/artificial lakes and sea in 2016.
In 2016, population served by water supply networks formed 92.2% of Turkey’s population and 98.2% of total municipal population.
While 3.24 billion m3 of water was drawn for municipal potable water supply in order to be distributed in 1994, this number increased to 5.84 billion m3 in 2016.
According to 2016 data, the ratio of the population of the municipalities served by drinking water treatment plants was calculated as 55% in the population of Turkey and 58.6% in the population of municipalities.
Out of 5.8 billion m3 of water delivered through water supply networks, 3.4 billion m3 (57.4%) was treated in drinking water treatment plants. 92.9% of this amount was treated by conventional methods, 6.1% was treated by advanced methods, and 1% was treated by physical methods.
