1968 - 1970

Beginning of export activities

The concrete start-up of international activities took place between 1968 and 1970 with the creation of a joint-venture purporting to allow SADE to make a commercial proposal leading to the construction of the Abu Dhabi water supply and sewerage networks.

1969 - 1970

At the same time SADE's Regional Division of Rouen won a first contract carried out in 1969-1970 in Belgium prior to the company’s installation in the country.


Moving International projects

Export activities began with a design study file concerning water and sewerage networks for the future Libyan capital, Al Bayda, entrusted to SADE in 1967. However, the project was abandoned due to the country’s political context.

Two new departments are created

In the 1950s and 60s the company launched two new departments, one specialising in drinking water treatment and the other in the depollution of waste and industrial waters.
