Operation of the Donchery wastewater treatment plant and potable water network

Summary

The tender covers the operation of Donchery’s wastewater treatment plant and pumping stations, together with the operation of its potable water distribution network. It is divided into two lots and uses a composite framework agreement with a fixed-price component and an order-based component. Lot 1 has an initial term of 48 months and may be renewed once for a maximum total of 96 months; Lot 2 has a 54-month term without renewal. Bidders may submit offers for both lots. Offers must be submitted electronically in French, with no variants permitted. The procurement requires a social inclusion action and environmental measures. The notice sets the submission deadline at 19 October 2026 at 16:30; bidders should verify the current deadline and any amendments on the procurement portal because the consultation rules document contains an earlier date. Offers are evaluated on technical value (50 points), price (40 points) and environmental value (10 points). Lot 1 requires a mandatory site visit unless the bidder can otherwise demonstrate thorough knowledge of the site and its constraints.
