Source of Water in Yogyakarta, Indonesia

Tap water in Yogyakarta is supplied mainly by PDAM Tirtamarta from groundwater wells and natural springs. Some of these sources are located in and around Sleman Regency, on the slopes of Mount Merapi north of the city.

The water is treated and distributed through Yogyakarta’s municipal pipe network. Many households also use private groundwater wells, especially in areas without full PDAM coverage.

Yogyakarta Drinking Fountains

Public drinking fountains in Yogyakarta should not be assumed safe unless they are clearly marked as potable and regularly maintained by a responsible authority. Water quality can be affected by dispenser hygiene, storage tanks, pipes, and irregular cleaning even when the original supply meets Indonesian drinking-water standards.

For visitors, bottled water or water from a trusted filtered and disinfected system is the safer choice. Avoid fountains with unclear maintenance, damaged fixtures, unusual taste or odor, or visibly dirty surroundings.
