Webuild Riachuelo Enviromental Recovery Plant - The Risers Concept


Webuild has won a prestigious ITA Tunnelling Award 2021 for an innovative and environmentally sustainable project an important part of the efforts to clean up the Riachuelo River in Argentina. Recognised as the Technical Innovation of the Year, the Riser Concept is a diffuser system with a series of vertical risers installed along a hydraulic tunnel under the River Plate in Buenos Aires to facilitate the discharge of treated wastewater from the Matanza-Riachuelo Basin, one of the most polluted in the world.

The system, developed by the Group and under review for patent protection, was conceived for Outfall Projects potentially applicable to densely populated cities. The system foresees the excavation and construction of vertical shafts (from the bottom to the top) along the sub-fluvial tunnel. It reduces the time needed to complete projects of this kind, whilst minimizing risk and reducing environmental impact.
