Úpravna vody Podhradí, Water treatment facility in Podhradí, Czech Republic

Úpravna vody Podhradí is a water treatment plant built in 1954–1962 as part of the Ostrava regional water supply, treating raw water from the Kružberk reservoir. Its reinforced-concrete skeleton with brick infill was designed by architect Cyril Kajnar, and above the entrance is Vincenc Makovský's last large relief, from the 1961–1964 cycle "Water in Our Life".

The facility was built following a government decision in 1954 to create a water system from Kružberk dam and became operational by the end of 1958. The project represented a major infrastructure development of that era.

The building displays a large relief titled "Water in Our Life" created by artist Vincenc Makovský in the early 1960s. This artwork shapes the site's appearance and reflects society's dependence on clean water.

The plant is an operating industrial facility and cannot be visited; the grounds and buildings are closed to the public. Its structures stand in Podhradí, reached by road from Vítkov. The relief by Vincenc Makovský is on the entrance section, visible from outside the complex.

The structure was designed as a symbol of post-war infrastructure development and stands out for its functionalist architecture. This design makes it a notable example of both technical and aesthetic ideals of that period.
