Pražská vodohospodářská společnost (PVS) is a municipal company that carries out construction and operation of water management infrastructure for the Capital City of Prague, chiefly wastewater treatment plants [1][2].
Treatment plant in Vinoř
In September 2026 PVS began the modernisation and expansion of the branch wastewater treatment plant in Vinoř. The project was presented to journalists on 23 September 2026 [2]. Investment costs are around CZK 503 million, and the plant's capacity is to grow from 8,923 to 16,500 population equivalents [2]. The construction is carried out, following a public tender, by the consortium Společnost ČOV Vinoř, formed by SMP Vodohospodářské stavby, VHS stavby, ARKO TECHNOLOGY and SMP Construction. The reconstruction is to last 84 weeks and be followed by a one-year trial operation [1][2].
The existing facility treats wastewater from Vinoř and from a significant part of the surrounding municipalities and, according to PVS, has been working at the limit of its capacity for several years. A connection moratorium (stopstav) was once declared there, restricting the connection of new residents [1][2]. The works include remediation of the biological lines, new settling tanks, a coarse pre-treatment building, sludge management, an operations building, a pumping station, a blower house and a transformer station. The plant must remain in operation during construction. The project requires coordination with the preparation of the section of the Prague Ring Road between Satalice and Březiněves, whose tunnel route extends into the area of the plant [2].
PVS chief executive and chairman of the board Pavel Válek stated that the city's approved concept envisages removing connection moratoria at all branch treatment plants in Prague by 2030 [1][2]. Deputy Mayor for infrastructure Michal Hroza (TOP 09) named the coordination with the construction of the Prague Ring Road and keeping the plant in operation as the main challenge [2].
Other treatment plants and projects
PVS recently completed work on the treatment plant in Nedvězí. Expansion projects are at various stages of preparation in Březiněves, Čertousy, Kolovraty, Lochkov, Dolní Chabry and Koloděje [1]. The company intends to connect several branch plants to the central sewer system discharging at the Central Wastewater Treatment Plant on Císařský ostrov. The districts of Běchovice and Dolní Počernice were connected this way, so the facility in Běchovice could be closed down [1].
In recent years a new water line costing more than CZK 7 billion was built at the Central Wastewater Treatment Plant. According to Pražský deník, the reconstruction of the old line, costing CZK 4.79 billion excluding VAT, is to begin in October 2026. The city also plans modernisation of sludge management there and a facility using residual heat from wastewater to heat households [1].
