Summa’s extensive experience in construction and upgrades of process automations systems in major wastewater facilities, in addition to good management in the areas of programming, panel manufacturing, and commissioning allowed for the successful completion of the project.

Background

The “D” Building project is part of the goal of eliminating odours coming from Ashbridges Bay Wastewater Treatment Plant under a comprehensive air management strategy developed by the City in 2007. The strategy involves at least six construction contracts with construction beginning in 2009 and expected to be completed in 2019. The long construction period is necessary to ensure normal and efficient operation of the Ashbridges Bay Treatment Plant during construction.

This project involves improvements to the “D” Building preliminary treatment and grit / screenings handling process along with installation of a new biofilter with a dedicated stack (construction 2010- 2013).
