SADE is building 2 twin XXL lifting stations for the rainwater collection, treatment and discharge project launched by Caen Normandie CCI. Identical and 50/50 These 2 underground concrete structures, located at either end of the platform, are absolutely identical. They are 7.50m high, 6m long and 3.60m wide, and house four 1,600m3/h pumps operated on a 3+1 basis. Each station is sized to lift half the volumes collected on the site up to a nearby retention and containment basin, meaning the 2 stations treat 100% of the rainwater. A tried and tested methodology The… +

The gutter-shaped stormwater main crossing the quarry overflows regularly, contaminating both the quarry floor and waters from the regionally-important Bathonian reservoir that rise up into the galleries. To resolve these issues, SADE was tasked with handling the gravity ducting (5mm/m) of this 150m segment. Since mid-June, the Giberville agency team has been setting up and slotting together the 64 concrete… +

Intervention in the framework of a colossal project for GRT Gaz. Due for commissioning in 2021, the Landivisiau natural gas-fired combined cycle power station will strengthen the security of electricity supply in Brittany. At present, the region produces only 10% to 15% of the electricity it consumes and is therefore highly dependent on its neighbours. Discover the video of the Landivisiau site To enable its connection to the natural gas supply distribution network, GRT Gaz must lay 22km of 400mm-diameter gas pipeline across the Finistère region. The new network will cross some ten municipalities, starting… +
