Caen La Mer intermunicipal authority selected SADE (Rouen Regional Division) to manage a worksite to restructure the rainwater system crossing a giant abandoned underground quarry in Fleury-sur-Orne. A wastewater treatment worksite with multiple challenges. An environmental issue. 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… +

On a highly technical worksite with a short lead time requiring serious SADE Group resources and wide-ranging know-how. SMAV (Valenciennes Intermunicipal Wastewater Treatment Authority) selected SADE to extend its wastewater treatment network, including renovating 2 building complex connections. This project is the final phase of a major overhaul of the public wastewater treatment network. Its primary aim is to stop discharging wastewater into the La Balhaut stream. And also to reroute it to the River Escaut and reduce demand on the WWTP, which has until now handled 100% of the water from the system. 2 apartment buildings, 1… +

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… +

With the construction of a 7.7km section of this 20km-long heating network, SADE is playing a big part in this environmentally-responsible project. Since 2017, Covalys has operated the energy recovery centre in Halluin, a town located in the Greater Lille area. Under the terms of its outsourcing contract, Covalys began building work on a major energy recovery centre extension: a 20km heat distribution network, including a 7.7km section built by SADE. A key component of Greater Lille’s energy climate plan The Halluin energy recovery centre burns… +

The aim of this dewatering system is to transport water from the water table lowering system set up on a gigantic urban redevelopment site in Asnières-sur-Seine, not far from the River Seine (of course), a further 390m to join a wastewater system operated by SEVESC. An overhead system This gravity system features 12m steel tubes (Ø 300 and 400) installed at an average height of 4.5m on hangers designed by SADE Ingénierie. The facility’s 37 hangers, each weighing around 10t, were built on public roads, mainly along Rue Henri… +

Aim: making teams aware of the environment. Action: recycling competition. Result: 526kg of plastic collected by 142 staff. For 3 months, 12 teams set to work, under the orders of Sade Ecuador’s HR Unit, collecting plastic bottles on the streets of Guayaquil. These were then weighed and sorted, before being sold to a recycling firm. For this campaign, each team chose a name to go with this good cause. Our top 3 environmental defenders were: Well done to all the participants and congratulations to the Ecuadorean HR Unit on this fine scheme!… +
