Vršovice waterworks in Michle, Industrial water tower complex in Michle district, Prague, Czech Republic

The Vršovice waterworks in Michle is a complex built in 1906–1907 by the town of Vršovice, comprising a 42-metre brick tower reservoir with a copper roof, an underground reservoir with two 13 x 13 m chambers holding 12,000 m3, a pumping station and a dwelling house, all designed by Jan Kotěra.

The complex was completed in 1907, designed by architect Jan Kotěra with technical plans by Jan Vladimír Hráský, to supply Vršovice with drinking water, later also Braník, Krč and Michle. In the 1920s petrol engines were replaced by electric drive, and in 1927 the works were connected to Prague's mains. The tower reservoir fed water from Podolská vodárna to Vinohrady and Vršovice until 1975.

Locals call the complex the Vršovice or Michle waterworks, and the tower is a protected cultural monument since 1958. Its unplastered brick facades and copper roof combine elements of Modernism and geometric Secession, designed by Jan Kotěra.

The complex stands on Zelená liška in upper Michle, Prague 4, beside the former Janeček arms factory (later Jawa, then ČKD Polovodiče), near Hanusova street and the border with Krč and Nusle. The tower is easy to see from the Chodovská radiála heading toward the D1 motorway, on the right. The grounds belong to Pražská vodohospodářská společnost and are not open as a regular visitor site.

The water was chlorinated here, likely making this Prague system the first in Czechoslovakia to use chlorine. Water came from wells in Braník, was pumped into the underground reservoir, then lifted to the tower.
