Real time control (RTC) technology can be defined as the dynamic management of a wastewater network in order to improve operation and flow management. Unlike static management, dynamic management allows for the distribution of flow in time and space throughout the network. The automation of key flow control structures and regulators can significantly improve the use of available conveyance and storage capacities with the continuous and strategic adjustment of control devices according to monitored conditions.

Tetra Tech CSO brings unparalleled experience for the design and implementation of RTC systems ranging from the simplest form of local reactive control to sophisticated system-wide predictive and centralized decision-based control systems using online optimization processes. Our proven track record has been demonstrated through the successful delivery of nine fully implemented and operational RTC solutions, to the complete satisfaction of our clients:

• Quebec City (QC), operational since 1999;
• City of Laval (QC), operational since 2002;
• City of Montreal (QC), operational since 2004;
• Louisville MSD (KY), operational since 2006;
• Paris, France, operational since 2008;
• City of Ottawa (ON), operational since 2010;
• City of Wilmington (DE), operational since 2012;
• Urban Community of Bordeaux, France, operational since 2012; and
• Lorette River Sub-watershed in Quebec City (QC), the first stormwater and flood protection application using RTC, operational since 2013.

Tetra Tech CSO is currently working on two other exciting RTC projects that are under various stages of implementation, namely for the City of Hamilton, ON and for the City of Edmonton, AB.
