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

Further proof that “united we stand, divided we fall”, and that SADE Group synergies are more than mere words!
In spring 2019, Bruno KEMPT, then working in Brussels, was looking for a team to manage a wastewater treatment worksite in the very heart of Brussels. Five staff from the Nantes Agency signed up for 3 months to assist our Belgian allies.
In mid-May 2020, this first technical worksite led to a second: the same team hit the road again to work on a second project involving the same issues: major depth, large diameter,… +
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… +
In Belgium, just as in France, multiple measures were put in place to combat the COVID-19 pandemic.
Let’s take a tour of the SADE Group’s sites across the country during this complicated period.
Government measures forced ARGEA to shut down its worksites, except for a few urgent works deals in public service sectors. A look back at the last few weeks.
Mid-March – mid-April
During the first 4 weeks of strict lockdown, ARGEA worked on adapting its working procedures and purchasing new PPE to comply with sanitary measures and optimise its preparations to get back to business.
15 April:… +
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!… +
With the arrival of drinking water as far as the town of Gagnoa!
For the last 5 years, the project to supply drinking water to the towns of Sinfra and Ganoa has been emblematic for the SADE Group, and not just in the Ivory Coast!
It is now nearing completion. After the 20,000m³/day treatment plant commissioning phase managed by teams from SIng, Franzetti Ivory Coast rinsed 120km of pipes from the plant to the intermediate uptake plant in Sinfra, then all the way to the town of Gagnoa.
The pipes are currently being disinfected, in collaboration with the future operator,… +
ARGEA confirms its position at VIVAQUA.
Vivaqua (previously Compagnie Intercommunale Bruxelloise des Eaux, i.e. the Brussels intermunicipal water authority) is one of Belgium’s biggest intermunicipal drinking water producers and distributors.
ARGEA, our Belgian subsidiary, is a historical partner of VIVAQUA. Over the last few weeks, it has confirmed its position as a go-to partner for this essential client by renewing all its framework agreements (called marchés stocks or stock agreements in Belgium) to carry out works to renovate, lay or connect sewers in the Brussels-Capital Region for up to 5 years:
Connection package: it is ranked 2nd out of 3… +
77 over the last 3 years and SADE has no plans on stopping any time soon!
These simple, sturdy, 100 to 200m³, on average 20m-high water towers are designed to supply multiple rural communities in Senegal.
They previously consumed surface water or water from shallow wells, which are both vectors of multiple diseases and becoming depleted due to the widespread lowering of water tables in this region of the Sahel.
In addition to the construction of these water towers, nearly 1,000km of PVC pipes have been laid, plus hundreds of livestock drinking troughs, standpipes for villagers and brackets for carts… +
SADE recently won its second deal using both microtunneling and traditional techniques for AyA (Instituto Costarricense de Acueductos y Alcantarillados).
The project is called “Construcción de alcantarillado sanitario, colectores sur : desvío Maria Aguilar y extensión aserrí”.
It will cost €13.6 million, is funded by the IADB (Inter-American Development Bank), and is set to take 18 months.
It involves the installation of sewer mains:
1,660m (⌀ 600mm) using a microtunnel boring machine (MTBM),
915m (⌀ 1,200mm) using a MTBM,
4,533m in an open trench (⌀ from 100 to 1,200mm).
Official notice of the award of the Maria Aguilar project has… +
