VINCI wins the contract to upgrade
Prague’s main wastewater treatment plant
- A large-scale upgrade of a critical infrastructure asset
- A €192 million contract
Prague’s water management company has awarded the contract to upgrade the city’s central wastewater treatment plant to a consortium1 led by a VINCI Construction subsidiary.
Works on the €192 million contract, which include dismantling existing equipment and demolishing then rebuilding 40 structures, will begin in October 2026 and take 43 months to complete. Most notably, eight of the 20 settling tanks will be rebuilt, four will be refurbished, and all facilities will be refitted with new water treatment technologies.
The aim with this reconstruction project is to rehabilitate and modernise a vital water management infrastructure asset, which has been in operation for more than 50 years, improving water treatment quality while optimising energy consumption.
The measures to limit the project’s environmental impact will include reusing materials on site and using rainwater and recycled water throughout the works.
VINCI Construction is a long-standing player in the Czech Republic, where it generated over €1.2 billion in revenue in 2025. The VINCI Group is also active in the country through VINCI Energies, which primarily provides electrical infrastructure solutions, and VINCI Concessions, which holds the public-private partnership contract for the D4 motorway (Via Salis).
1 Five VINCI Construction subsidiaries (SMP Vodohospodářské stavby, SMP Construction, ARKO Technology, PRŮMSTAV, Stavby mostů), Česká voda-Memsep (Veolia group), Hochtief CZ and Hochtief Infrastructure GmbH.
