Parallel to the increase in public concern about the safety of drinking water globally, the demand for bottled water has increased in almost every country. Although tap water is significantly cheaper than bottled water, consumers concerned about the safety of tap water. They still prefer the bottled water despite several checks implemented in tap water networks. The present paper aims to discuss network water quality in the city of Istanbul, Turkey and to present the findings on a related survey conducted by the authors. The survey was conducted with the participation of 980 individuals living in different districts in Istanbul and the findings were assessed to determine the public perception about tap water quality and bottled water consumption especially after the experienced years of drought and water quality concerns. Findings demonstrated that several individuals never drink tap water and certain individuals do not utilize tap water at all. It was found that only 4% in the surveyed group drink tap water without hesitation. Based on survey findings, the abovementioned group was mainly among the lowest income group in the sample. When purchasing bottled water, several individuals preferred the well-known brands. It was found that the most significant reasons for preferring bottled water were the nice taste of the bottled spring water, which was perceived not to exist in tap water. It was concluded that drinking water treatment facilities and regulations are required to cater the future quality demands. Furthermore, it was determined that adequate inspections and controls on network water are necessary.
