Expansion and Modification of the Aïre Wastewater Treatment Plant

Project

The Services Industriels of Geneva (SIG) have initiated a large-scale project at the Aïre Wastewater Treatment Plant (STEP).

Originally designed to treat carbon, nitrogen, and phosphorus pollution for a capacity of 600,000 inhabitants, the plant is now operating over capacity. It is currently overloaded with carbon pollution equivalent to 750,000 inhabitants. To address this, the plant is undergoing an expansion to meet the needs of 1 million inhabitants by 2050, focusing on increasing its biological treatment capacity.

Mission

For this project, SIG has engaged setec opency to provide expertise in Lean Management, including:

• Lean Construction awareness initiatives
• Yellow Belt Lean Management training

setec opency brings its project management methodologies and collaborative tools to unite all stakeholders around:

• Timeframe challenges
• Detailed coordination of studies
• Construction activities and overall site organization on an operational plant.

This mission aligns with the sectors that setec opency aims to further develop as part of its “Engineer & Citizen” initiative, as well as with the new focus areas identified for strengthening within the Stratency framework.
