this consultation concerns a project management contract for the development and rehabilitation of the Savenay wastewater treatment plant.

This file follows a feasibility study to improve the functioning of the sanitation system in the municipality of Savenay launched in 2020.

A Water Law study was initiated at the end of 2022. Also, the holder of the project management contract will therefore have to approach the service provider in charge of this case, in order to take into account this constraint.

the development of the treatment plant, whose nominal capacity will be increased from 9500 p.e. to 11500 p.e., consists mainly of the addition of pre-treatments (capacity increased to 235 m3/h), the conversion of existing SBR cells into aeration tanks and the construction of 2 clarifiers on the plot located north of the current site
