Though ski resorts might not be opening back up right away, some will be ready and raring to go for the season because our Regional Divisions are hard at work!
Thanks to fast work by our Metz and Lyon Regional Divisions, two resorts’ water systems are being given a major makeover.
Water for snow-making machines: no SADE, no snowflakes!
In Haut-Rhin, SMMGM (i.e. Markstein Grand-Ballon massif joint development agency) wanted to extend the Markstein ski resort’s snow-making system. To meet this demand and supply 9 new snow-making machines, the Metz Regional Division (Alsace Agency) set up:… +
…with SADERTELEC, which renewed its framework agreement with the electricity transmission company.
Do we still need to introduce SADERTELEC, our subsidiary that works exclusively for RTE, and whose headquarters are based in Marseille?
A little history, all the same…
It was back in 2009 that the Marseille Regional Division got in touch with the electricity transmission company, realising that burying very high voltage lines (63 to 400KV) was a fast-growing business. Our initial aim was to offer specific structural services, particularly microtunneling with STS.
In 2013, a new entity was created to specifically focus on this business line: SADERTELEC. This… +
SADE Group is bolstering Bouaké’s drinking water supply for PFO Africa, head of the consortium awarded the overall contract by the Ivory Coast Hydraulics Ministry.
After work began on the site at the end of March 2020, COVID-19 put a real spanner in the works: repatriation, temporary site shutdown, plus new health & safety rules. The project practically ground to a halt for several months, leading to comprehensive reorganisation last July.
Since then, 3 teams armed with an impressive selection of excavation equipment have been working 6 days a week to meet the deadline: two Ø 1,200 teams and one… +
A flagship worksite featuring an original technique developed by the experts of SADE Special Works.
Currently, SADE Special Works is handling the earthworks for this 24.25m x 7.45m, 43m-deep rectangular shaft.
Positioned in Paris on Avenue Friedland, which stretches from Boulevard Haussmann all the way to the Arc de Triomphe, the “Friedland shaft” will provide ventilation and emergency access for the future RER E regional express train station by 2022.
It is nestled in a dense urban environment, surrounded by sensitive sites: RER Line A, which runs 4.85m from its walls and the many Haussmannian buildings lining the avenue.… +
Down near Dax, the small town of Castets plans to position itself as the new surfing El Dorado by playing host to a tourist complex, complete with a giant wave pool.
This project and the population growth it will entail mean the town’s WWTP’s capacity needs to be doubled in advance. The Les Landes SYDEC (Departmental Municipal Equipment Authority) has selected SADE (head of consortium) and its partner Gallego for this mission.
The goal, is to design and build the new infrastructure and partially modify the existing systems to boost treatment capacity from 2,750 PE to 5,500 PE,… +
With the award of the contract to renovate the Méry-sur-Oise drinking water production plant decanting unit for SEDIF as part of a consortium alongside SETHA.
Since the changes made to the terms of SEDIF’s service delegation contracts, drinking water plant contracts had become few and far between for the Greater Paris Regional Division. But that doesn’t mean it’s lost its touch, and it’s now back with a bang with this valuable contract won by the Argenteuil Agency.
The contract in brief
As head of the consortium, SADE won Package 2, along with its partners SETHA and INEO (ENGIE’s electrical engineering… +
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 “point B” plant and tanks, located in the heart of Dakar, form the input point of Dakar’s main water supply pipeline: ALG 1.
After observing the existence of malfunctions and leaks, the operator, SEN’EAU, selected SADE to renovate two key components of the system, which involved totally shutting off the capital’s water supply.
Replacement of a leaky valve (ø1,000mm) on the ALG1 pipeline
Repair of a leaky pipe (ø600mm) at the start of the distribution network by fully replacing the valves and fittings in the output manhole.
To replace the faulty parts within the deadlines, teams from… +
Signed on October 6, 2020: a fine victory for SADE Costa Rica, assisted by the Group’s Head Office IT Department Support Division.
Aya, which is SADE Costa Rica’s main client, is the state-owned company that manages drinking water and wastewater treatment service for 80% of the country’s population.
It recently selected SADE for the biggest network extension project is has ever launched: a gigantic wastewater collection and treatment project for more than a million users in the country’s capital, San José, protecting rivers from WW discharged into the natural environment… +
Montmartin-Hauteville-Annoville and Lingreville wastewater treatment authority is getting stuck into the renovation of the current Montmartin-sur-Mer WWTP, built back in 2005.
This WWTP’s incoming backflow station had one weakness: the input, via multiple force mains, of H2S gas (hydrogen sulphide) that oxidises the facility’s concrete structures and its upstream manhole.
The Rouen Regional Division was awarded this worksite as lowest responsible bidder in June 2020, proposing the construction of a new HDPE station, near the existing one, so as to guarantee a fully-waterproof and non-H2S sensitive facility.
The works, which began in August 2020, include:
the fitting of an upstream… +
