The Vltava river is 430.3 kilometres (267.4 mi) long and drains an area 28,090 square kilometres (10,850 sq mi) in size, over half of Bohemia and about a third of the Czech Republic's entire territory.As it runs through Prague, the river is crossed by 18 bridges (including the Charles Bridge) pictured here and covers 31 kilometres (19 mi) within the city. The water from the river was used for drinking until 1912, when the Vinohrady Water Tower ceased pumping operations. It is, however, the source of drinking water in case of failures-repairs to the water supply from the Želivka and Kárané sources. The Podolí water processing plant is on standby for such cases with the long section of the river upstream of the Podolí plant under the stricter, second degree of pollution prevention regulations.
