Drees & Sommer working with AQUALEX towards a more sustainable world

It all began in 1970 in Stuttgart when Gerhard Drees decided to set up a small engineering office. His colleague Hans Sommer and he never imagined that this small team consisting of three people would evolve into a top international company employing more than 4,500 people at 51 different locations. Innovation, 'thinking outside the box' and a strong focus on sustainability are still the top three values distinguishing Drees & Sommer.
