One plant at a time

Montmartin-Hauteville-Annoville and Lingreville wastewater treatment authority is getting stuck into the renovation of the current Montmartin-sur-Mer WWTP, built back in 2005.

The Rouen Regional Division was awarded this worksite as lowest responsible bidder in June 2020, proposing the construction of a new HDPE station, near the existing one, so as to guarantee a fully-waterproof and non-H2S sensitive facility. The works, which began in August 2020, include: the fitting of an upstream...
