Since July 2019, Cardinal Benrardin Gantin international airport in Cotonou has been getting a makeover. Franzetti Benin has been one of the key contributors…
A welcome works extension!
The Benin government had planned to build a new international airport, Glo-Djigbé, outside Cotonou over the next 3-4 years to replace the existing Cardinal Bernardin Gantin airport, to welcome more than 1 million passengers per year. Franzetti was set to play its part in this transition by giving a fresh lick of paint to the existing building.
Given the current airport’s capabilities, the government ultimately decided to delay the construction of this… +
With the total rehabilitation of an accessible sewer main in Boulogne and a worksite combining chemistry and public works.
Seine Ouest Assainissement, a subsidiary jointly owned by Veolia and SADE, has been awarded the wastewater treatment public-service outsourcing contract for GPSO (Grand Paris Seine Ouest, i.e. Greater Paris West Seine) up to the end of 2027. SOA’s contract covers approx. 60 replacement and/or rehabilitation operations on systems in 8 local towns and villages. One of these is the consolidation and rehabilitation of a section in Passage des Abondances (Boulogne-Billancourt).
Did you say “accessibility”?
Until now, the design & construction operations… +
An outstanding success for the SADE Group with the signing of 3 contracts with Veolia Africa and Veolia Ivory Coast.
The project’s overall aim is to meet the country’s second largest city’s growing demand for drinking water. SADE was already previously selected by PFO (General Contractor) to carry out the civil engineering design work on these same facilities.
Description of the new contracts
The latest 3 contracts cover the detailed design, construction and commissioning of the facilities for the new plant, as well as its intermediate lifting station. They are included in the first package of the new plant, which… +
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… +
By heating this centre of sporting excellence using wastewater systems.
The Nice Agency (Marseille Regional Division) has partnered with Veolia to install Energido systems down on the Côte d’Azur. Two years after the first worksite was completed in Saint-Laurent-du-Var, it’s now the turn of Antibes water-sports stadium.
A profitable solution: using heat from a public sewer main
Antibes City Council launched the project to redevelop the water-sports stadium’s outdoor facilities, opting to recover energy from wastewater systems to heat the pools.
The recommended and selected energy solution recovers heat stored in the public sewer main running past the site on… +
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.

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… +
SADE Group is starting to lay the water supply system for Ivory Coast’s 2nd biggest city, 350km from Abidjan.
Covered in wooded savannah and surrounded by cacao and coffee tree plantations, the city of Bouaké, formerly Gbékékro, lies in the centre of the Ivory Coast. It is encircled by a network of 143 villages, spreading 20km out from the city.
Bouaké is the department’s administrative centre and has 542,000 inhabitants in the city itself and more than 1.5 million if you count all the surroundings towns and villages. As part of the vast hydraulic restructuring programme launched by the country’s… +
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… +
Work will begin in Paris this summer on the vast programme to make the Seine swimmable for the 2024 Olympic and Paralympic Games.
This Paris City Council action plan covers, among other things, the construction of a storage-treatment-return basin in Austerlitz and several sewer mains down by the River Seine. The aim of this project is crystal clear: to drastically reduce overflows of wastewater from Paris’ wastewater treatment systems during rainy weather to ultimately improve the quality of the waters of the River Seine.
Officially announced only very recently, the contract was awarded to a consortium of 5 firms by… +
