Stantec’s water team in Ottawa has been honoured with the Environment Award for their real time control (RTC) system for the City of Ottawa’s combined sewer system. The Environment Award was presented at a gala in Toronto on Saturday by the Consulting Engineers of Ontario (CEO).
Stantec and its partner, BPR-CSO, implemented RTC based operating strategies for the City of Ottawa’s combined sewer system. Real time control operation of wastewater collection systems is a relatively new field that involves the automated control of operations in response to observed and/or predicted conditions. The system takes advantage of existing piping through the City to control wastewater flows, minimizing the need for new and costly infrastructure.
In its first year of operation, the project has led to a significant reduction in the amount of combined sewer overflows to the Ottawa River. In addition, the new system provides operators with a complete system view, enhanced reliability and greater flexibility to facilitate maintenance or respond to emergency conditions.
