Despite the Dry Season, No Water Shortage but We Need to Avoid Waste

As we experience the last days of the summer season, the fill rate of dams in Istanbul shows 46.88 percent. There are no water scarcity problems in the city, which has 14 different water resources, including Melen and Yeşilçay, despite the driest summer in the last seven years.

Istanbul Water and Sewerage Administration (İSKİ) officials said Istanbul has undergone a drought every seven years, adding there will be no water shortage even in case of a year-long drought or below-average rainfall.

Istanbul, which is larger than the 23 countries of Europe with its population, Some 2.8 million cubic meters of water is consumed in wintertime and 3 million 200 thousand cubic meters of water is currently consumed in the summertime in the city every day and the current water volume is 407 million cubic meters. The water level in the city's dams remained normal compared to previous years.

According to “Istanbul Water and Sewerage Administration” (İSKİ) data, the water level at Istanbul's dams that provides drinking water to the city has fallen to 46.88 % full, with only 407 million cubic meters of water left for use. The seven dams and various ponds feeding Istanbul's water supply line can hold a total of 868 million cubic meters.

Some 3 million cubic meters of water is currently consumed in Istanbul every day. In addition to the dams providing water for the city, some of the city's daily water needs are supplied in part from Melen and Yeşilçay regulators with a capacity of up to 1 million cubic meters per day.

The rainy season in Istanbul lasts seven months, from October 1 to April 30, with a greater than 19% chance of a given day being a wet day. Therefore, the occupancy rate of the dams is expected to increase, as the rainy season approaches in the city.
