Podkrušnohorský přivaděč, Water supply system in Chomutov, Czech Republic

The Podkrušnohorský přivaděč is a water supply network in Northern Bohemia that spans 33.8 kilometers through channels, underground pipes, reservoirs, and an aqueduct. The system links the area around Klášterec nad Ohří to Jirkov, delivering water to industrial facilities in the region.

Construction of this water infrastructure began in 1957 and continued until 1982 to meet industrial water demands. The project also responded to the need to control flooding that originated in the Krusne Mountains.

The system's name is used loosely: maps label the whole channel Podkrušnohorský přivaděč, while the stretch up to Březenec is officially the Přivaděč Ohře–Bílina. It is owned and managed by the state enterprise Povodí Ohře, and a small hydroelectric plant sits on the underground section beneath Březenec between Chomutov and Jirkov.

The canal runs from Rašovice on the Ohře, where pumping station Rašovice lifts the water, past Ciboušov and Chomutov to the Březenec reservoir and on to the Újezd reservoir. A 142-metre aqueduct carries it over the Chomutovka in Chomutov, and between Chomutov and Jirkov it runs underground beneath Březenec. The channel is covered with concrete panels for 2.2 km to protect the overflow structure from freezing.

At river kilometre 1.46 a distribution structure diverts water through a 1.26 km connecting channel, 12 m³/s capacity, to the Bílina intake at the start of the Ervěnický koridor. Near Málkov the channel also collects water from the upper Hutná, a stream cut off by the open-cast mine.
