A nick name for the old water pumps. You can find old pumps all over the city that don't work, that were actually pumping water from wells in their time. But recently they decided to place a lot of "pumps" around the city that look the same way as the old thing but are actually connected to water system. And since we have high quality water in Zagreb, and all over my country you can safely drink it... A way to decrease the amount of plastic bottles... I love my city...
