The Dâmbovița River is a river in Romania. It starts at the junction of headwaters Valea Vladului and Boarcășu, having its source in the Făgăraș Mountains, and flowing southward. It passes through Bucharest and flows into the Argeș River 286 kilometres from its source, near Budești, in Călărași County. Dâmbovița County is named after the river.
For centuries, Dâmbovița was the main source of drinking water for the city of Bucharest. While there were a few dozen water wells, most of the water in Bucharest was distributed by water-carriers.
Bucharest folkore mentions the waters of Dâmbovița as "sweet", and even at the beginning of the 18th century, Anton Maria del Chiaro considered it "light and clean". However, toward the end of the century, as the population of Bucharest increased, the river ceased to be as clean, and hence the need of the aqueducts. The earliest aqueducts with public fountains (cișmele) were built during the rule of Prince Alexander Ypsilantis.
Dâmbovița is one of the most polluted rivers in Romania and the most important source of pollution of the Danube, into which its waters flow. When entering Bucharest, the river's water quality is already rather bad and below the recommended standards, but after exiting Bucharest its water are in the worst category, due to the hundreds of millions of cubic meters of raw sewage which are dumped every year directly in the river.
