The City of Ottawa proposes to implement an automated flow control (Real Time Control) system as part of the upgrade of five major regulators that control flow from collector sewers into the central Interceptor Outfall Sewer (IOS).
Whether you’re planning to implement a multi-million dollar robust Real Time Control (RTC) system or a scaled-down simple version, there are several critical elements necessary for successful implementation and utilization by the Publicly Owned Treatment Works (POTW) staff.
World Water & Environmental Resources Congress – 2005
In 1999, the City of Quebec commissioned a global optimal real-time control system (GO RTC) with rainfall and flow predictive capabilities for its westerly district wastewater system. This GO RTC system served mainly to reduce separate and combined sewer overflows in the St. Lawrence River and in the St. Charles River.
Ninth International Conference on Urban Drainage – September 2002
This paper presents a review of the current state of the art of real time control (RTC) of urban wastewater systems. Control options not only of the sewer system, but also of the wastewater treatment plant and of receiving water bodies are considered.
The operation of large interceptor systems is complex. In most systems, static regulators are used to limit inflows into interception systems and ensure that treatment plant capacity is never exceeded.
