Káraný water works

Káraný Water Works is a treatment facility along the Jizera River that filters water through multiple layers of gravel before sending it to consumers. The system uses both natural filtration and mechanical processes to complete the purification.

The facility began operations in 1913 as part of Prague's integrated water supply system to serve the capital with fresh water. Since its establishment, it has grown to become one of the main sources for supplying the city and surrounding communities.

The site demonstrates how water is sourced and treated for a major city, showing the practical side of modern water supply systems. Visitors can observe how nature and technology work together to provide clean drinking water to communities.

The facility sits about 30 kilometers northeast of Prague and is accessible by public transport. Visitors should note that tours are limited and advance booking may be required to enter.

The facility maintains several abandoned wells from its century-old infrastructure that are regularly inspected and upgraded. These older structures show how water technology has evolved across generations.
