Overflow Modification Works at Wastewater Treatment Plant

This French public procurement tender seeks a contractor to perform modification works on overflows A2 and A5 at the wastewater treatment plant in Chantonnay, Pays de la Loire. The core work involves general construction activities necessary to complete these modifications. Practically, this likely entails concrete work, pipework modifications, and potentially some earthworks or structural reinforcement, depending on the existing overflow structures and the desired modifications. Given the scope is limited to two specific overflow structures within an existing plant, the project is likely of medium scale. Complexity will depend on the specifics of the modifications required; however, working within an operational wastewater treatment plant inherently introduces logistical and safety considerations. Bidders should anticipate stringent safety protocols and potential disruptions to plant operations during construction. The tender was published on March 12, 2026, with a deadline of April 9, 2026, leaving a relatively short timeframe for bid preparation.
