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… +
CTHM pursues the development of its trenchless techniques.
The Régie Autonome de Kénitra (RAK) [Kenitra independent authority] is launching rehabilitation works on collector D, T230, located under the busy Mohamed Diouri Avenue, which links Place de la Gare to Oued Sebou, (1.5km).
The teams will rehabilitate this straight-lined combined sewerage system, gaining access via existing manholes:
On-site polymeric UV close-fit lining along a 224m-section in 500mm-diameter concrete
Concrete spraying along 1.2km of T230 ovoid sewers with rubble stone (a more suitable technique than the laying of liners for equivalent hydraulic capacity)
Pitting and levelling with mortar of 29 manholes… +
For the rehabilitation of wastewater networks in tourist areas.
Radeema and Amendis, experts in water cycle and Moroccan subsidiaries of the Veolia Group, are leading a multiannual works programme to ensure high-performance public service, save water resources and protect natural areas.
On behalf of Radeema, works in Marrakech will consist in the rehabilitation by UV close-fit lining of 200m of wastewater pipelines (400mm to 600mm-diameter).
The specificity of these pipelines is their location in two very busy tourist areas of the medina: one section in front of the Dar El Bacha monument, former palace of the Pacha of Marrakesh, and… +
…and is currently under way in Rabat!
At the initiative of His Majesty King Mohammed VI, the Moroccan Government launched a rehabilitation programme in Morocco’s 32 medinas to renew these living and business districts which are home to 750,000 people, i.e., 3.6% of the country’s urban population.
At present, 14 of these districts are undergoing active rehabilitation. This programme also enables CTHM, our Moroccan subsidiary, to stand out from the competition with the implementation of trenchless techniques which are particularly suited to these dense urban environments, made up of narrow lanes that are home to intense business and retail activity.… +
SIZIAF is the manager of a 460ha industrial estate located in the Douvrin and Billy-Berclau municipalities. It is responsible for the structural development, management and economic growth of the Artois-Flandres industrial park.
Geared primarily towards industrial companies, the first firm to locate to the estate in the late 1960s was La Française de Mécanique.
This industrial estate continues to grow today. A new 90ha plot was freed up and redesigned on the former Française de Mécanique site, notably for the firm ACC, winner of the French government’s recovery plan for the car industry and innovative entities. ACC is Europe’s leading… +
5 years after La Riche, Rennes RD and SADE Special Works pooled their expertise once more on behalf of Tours Métropole, for vast drainage works between Tours and Saint-Cyr-sur-Loire.
Broken down into two orders attributed to the Rennes RD and SSW, this 15-month, out-size task involved the extension of the drainage network to the north of the Tours metropolis, with the building of a primary collector to transport wastewater to the main treatment plant (La Grange) in La Riche, the ultimate goal being to close down all the small treatment plants in… +
Rustroff, a village in the immediate vicinity of the Grand Duchy of Luxembourg, needed to find a solution to improve its drinking water resource.
On overly-present element
Up until then, local springs served as Rustroff’s primary water source. The level of phosphates in these waters had been rising steadily for several years.
To restore a standard level, the municipal authorities opted for dilution, by mixing this spring water with water supplied by a neighbouring authority.
Following a call for tenders, the building of an interconnection network and automated facilities was entrusted to the Greater Metz RD.
A carefully developed project… +
The Loire-Forez conglomeration entrusted the SADE Group with the separation of a sewer mains section in the Saint-Just-Saint-Rambert municipality. Works were co-contracted by the local SADE agency and DPSM, our Toulouse-based subsidiary and rehabilitation expert.
Double, rehabilitate and separate
Along around 450m on Avenue des Barques, the task was to:
Rehabilitate a T180 ovoid
Build a stormwater collector in parallel (800mm-diameter concrete)
Create/modify all branch connections to separate stormwater and wastewater drainage along most of this section
The DPSM teams took care of the rehabilitation, while the Poitiers-Metz RD, and more specifically the Saint-Etienne branch… +
In Beaumont, as part of a project to install junctions to the Pourliat stormwater basin drain, Clermont Auvergne Métropole (CAM) called on SADE Special Works and the Poitiers-Metz RD (Clermont-Ferrand Agency), to create a stormwater collector using microtunnelling (1,200mm-diameter) along 635m.
Works were executed:
In two thrusts: the first along a straight distance of 240m and the second along 395m with a 200m bend of 400m radius
from a single entry shaft to two exit shafts.
Using standard techniques, SADE Special Works carried out the excavation works… +
From June to September 2021, SADE helped to create the wastewater system for the Terramesnil municipality, in coordination with Balestra TP. An ex-nihilo project for the Doullennais Inter-Municipal Drinking Water Authority to improve life for the 300 inhabitants of this village.
A coordinated worksite
SADE was responsible for laying, along 600m, a gravitational mains in 200mm-diameter sandstone, creating around 50 branch connections in 150mm-diameter sandstone, and the building of a pumping station and its discharge in 90mm-diameter HDPE along 300m. These facilities were located on clay-rich land at a depth of 1.3m to 2m. To avoid interfering with the harvesting… +
