Preliminary study for a Limoges storage and return basin to reduce discharges into the Vienne

Summary

Limoges Métropole is procuring project-owner assistance for two preliminary studies to define a programme for storage and return basins, upstream and downstream transfer networks, and two associated crossings of the Vienne River, with the aim of limiting discharges into the river. The firm tranche covers a basin on the left bank of the Vienne; an optional tranche covers a basin on Rue Legendre. Each tranche includes an existing-conditions assessment and diagnosis, hydraulic analysis, scenario proposals, and preparation of the project owner's programme. No separate lots are provided; the firm tranche is expected to take 17 months and the estimated duration including the optional tranche is 28 months.
