Overview
- Watrify’s interactive service lists about 250,000 public drinking-water points across Europe, according to July 30 coverage that highlights a growing continent-wide database.
- Germany offers multiple discovery tools: the BDEW-backed app Trinkwasser unterwegs, the Refill network coordinated by a tip: tap, and the Refill app from City to Sea that maps partner cafés and shops.
- Hamburg’s joint inventory lists 54 public dispensers—ten run by Hamburg Wasser and 44 at public toilets—with a 24/7 dispenser at the Bahnhofsmission and eight units inside the airport security area.
- Municipal operators say tap water is regularly tested, fountains use automatic flushing to keep pipes fresh, and many outdoor fountains are shut off in October or November to avoid frost damage.
- Mapping projects combine open municipal data, OpenStreetMap and community submissions, and coverage notes privacy differences: Watrify says it avoids tracking while some apps, including Refill, collect personal or GPS data but state limited technical use in their policies.
