…by obtaining France’s largest pipeline order in recent years.
The SADE (SADE Special Works and Île-de-France RD) – EHTP – SETEC HYDRATEC and CABINET MERLIN consortium recently won its bid for a 30-month design-building order from the ADP Group (formerly Aéroports de Paris).
ADP Group’s Marne project consists in the laying of a stormwater transfer pipeline from Paris-Charles-de-Gaulle airport to the Marne river. The pipeline path, which runs for some 9km between the municipalities of Gressy and Annet-sur-Marne, will enable the gravitational evacuation of water.
Led by SADE Special Works (agent), this complex project combines… +
…by rehabilitating a reservoir using the Hydroclick® process.
Vendée Eau entrusted the Rennes Regional Division with the rehabilitation of a 5000m³ reservoir in La Roche-sur-Yon.
Dates: from 2 November 2021 to 17 May 2023
A vast project
This was a technical feat for the Civil Engineering-Special Works Agency, which was responsible for the interior rehabilitation of the water tower:
Waterproofing of the tank by laying HDPE plates (Hydroclick® process)
Repairs, by rope access technicians, to the reduced-access steel riser mains
And exterior junction and asbestos disposal works to the pipelines
Its co-contractor, VERTICAL, was in charge… +
SADE and its teams are renovating the former mining towns, which were UNESCO Heritage-listed in 2012!
From the late 19th century to the late 1980s, the municipality of Sallaumines in the Pas-de-Calais department was a major mining hub managed by the Compagnie des Mines de Courrières. To retain the population, these private companies provided high-quality housing to miners and their families.
Perfect rows of red brick housing
Between 1900 and 1930, hundreds of comfortable houses were built for miners. The houses included a pantry, outdoor toilets, a porch and small garden, and varied in surface area according to the number… +
…with a heating network laid by SADE.
In 2025, Cannes’ iconic promenade will be revamped for pedestrian use, with green spaces and above all a heating network using seawater.
Renewable energy is at the core of this project. Building works will begin in 2025 on a thermal power plant which will capture and heat seawater by incinerating the city’s waste.
In preparation for the Croisette’s makeover, the municipality began by widening the beaches and renovating seaside establishments. The next step got under way in 2022, with the renewal of underground… +
FRANZETTI CI is a stakeholder in this project!
The Abidjan underground system is set to transport 180 million passengers per year as of 2028 and will revolutionise and streamline urban transport in this city.
The project, which crosses the city along its existing railway, is of course generating numerous works orders, in particular those linked to the transfer and protection of utility networks located in its future passageway.
The Line 1 project
This line adds to existing services which do not adequately meet the strong demand for transport between the various municipalities of the Abidjan Autonomous District. In addition to… +
SADE renews drinking water supply pipes.
Last November, François GROSDIDIER, Mayor of Metz, confirmed his wish to ‘restore a strong identity to Rue Serpenoise, an absolute emblem of the city’. By 2024, and in order to revitalise the city centre, the existing long street of red paving stone will be transformed with new paving and the installation of a unique urban structure named ‘La Sepertine’, composed of benches, arches, fountains for ‘drinking and refreshment’, misters and plants. At nightfall, passers-by will discover a play of lights revealing the Graoully

The Graoully is a mythical dragon-like beast, which… +
with the fitting of the diffuser, an essential pipeline element.
Power production units require a constant supply of water for the operation and cooling of circuits. To ensure an ongoing supply of sufficient quantities of water and maintain the safety of a plant, the formation of frazil ice is to be avoided at all costs.
To prevent this risk, the Rennes and Bordeaux Regional Divisions laid a hot water supply system in the vicinity of the pumping station grids and the sections requiring protection. The diffuser, located at the mouth of the network, is the pipe section via which the… +
SADE won two long-term work orders in Pont-d’Ain and Chavanoz, which began in May 2022 and are scheduled for completion in the second half of 2023. SADE is carrying out the sizing, execution plans, operation management, networks and all equipment, including electricity and automations.
The aim is to inaugurate the Pont d’Ain on 8 September 2023!
The task is to build a brand new 5000PE treatment plant and demolish the existing facilities located in the immediate vicinity. The mayor of the commissioning municipality set the inauguration of the new WWTP for 8 September 2023.
The goal is thus clear, and… +
…to protect the hospital from flooding.
Montpellier’s university hospital (CHU) encompasses several sites, including Lapeyronie Hospital, which owes its name to King Louis XV’s surgeon. Located downhill from natural terrain, it flooded regularly in heavy rain and required securing. The CHU thus launched large-scale works, entrusted to SADE.
Protective measures in a high-risk context
To begin with, the competent authorities initiated emergency works:
Building of an embankment along the hospital site
Raising by 3.5m of three access points to the hospital (car park, staff entrance, etc.)
Laying of a stormwater collector
A new phase entrusted to… +
After Boulogne, Villejuif Louis-Aragon and Créteil l’Echat, SADE is continuing its work!
Line 15 is an underground metro line (75km) which runs throughout the Greater Paris metropolitan area and forms an outer ‘ring road’. Its aim is to decongest the public transport networks and provide an efficient service to the departments surrounding Paris, by forming a regional network alongside the existing transport services. It thus offers the possibility to travel from suburb to suburb without having to transit via central Paris.
This ‘ring road’ consists of three sections, including Line 15… +
