To handle increasing amounts of rainfall and to prevent combined sewer overflow during heavy rain it is necessary to implement sewer separation in large areas of existing built city. One of the challenges facing this undertaking is the amount of excavation necessary when laying down new pipes.
To find a solution to this, Smith facilitated a development process with Aarhus Vand and two Danish contractors specialized in utilities management, Aarsleff and Østergaard, looking at the possibilities of developing no-dig approaches inspired by larger tunnel construction practices.
During the process, leading companies in the industry where brought together to identify promising development opportunities based on both know solutions and cutting-edge technology. By initiating an open development process, it was ensured that multiple opportunities were considered and the most promising development prospects chosen for the specific challenge.
