Station d’épuration Jean-R. Marcotte

This project regarding the ozone wastewater disinfection station at the Jean-R.-Marcotte plant stands as part of a larger program seeking to modernize Montreal’s water treatment infrastructure. Carried out by Réal Paul Architecte, in collaboration with SNC-Lavalin (now AtkinsRealis), this project aims to bring the plant up to contemporary environmental requirements and improve its processing capacity. 

The project includes the design and construction of six new buildings, each with a specific function, ranging from ozone and oxygen production to the management of pumping and cooling infrastructures, as well as an electrical substation and a building dedicated to ozone elimination.

Architecturally, the buildings blend harmoniously into the existing landscape of the site, taking into account the protected natural areas nearby, such as wetlands. The use of precast concrete and glass panels provides a modern and functional aesthetic, while specific architectural elements, such as perforations on the facades inspired by the molecular structure of ozone, add an innovative touch. The illumination of these perforations and internal installations enhances the visual identity of the project, particularly the bluish glow emitted by the ozonation process, visible from the outside.

This ambitious project has helped optimize the ecological performance of the Jean-R.-Marcotte station, while enhancing the safety and reliability of wastewater treatment. Réal Paul Architecte’s expertise played a crucial role in the success of this project, adhering to technical, environmental, and aesthetic constraints, thereby contributing to the improvement of Montreal's urban infrastructure.
