Water Drinkable Score: 70/100
The tap water in Surabaya comes primarily from the Brantas River via the Karang Pilang Water Treatment Plant, which has been upgraded over the years to handle the city's growing demand. The water contains essential minerals such as calcium and magnesium, but the mineral levels can fluctuate due to seasonal changes. Perusahaan Daerah Air Minum (PDAM) Surya Sembada Surabaya is responsible for water distribution, while the quality assurance falls under the Public Works Department of the city.
