Abstract

The Regional Municipality of Ottawa Carleton (PMOC) initiated the development of an operational model as part of the wastewater system Pollution Control Planning Strategy and the Master Planning process to give them a powerful tool for the integrated analysis of the Regional wastewater collection and treatment systems.

It was recognized, with the recent upgrade to the wastewater treatment plant, that an opportunity existed to review the operation of the Regional sewerage facilities to identify system configurations and control strategies that would provide cost-effective pollution control. The Region found limited information was available on the hydraulic operation of the interceptor sewers and regulating chambers, leaving them in a position of not being able to make informed operational decisions. As well, the Region was unable to identify remedial or operational measures that would complement the upgraded capacity of the wastewater treatment plant. To this end, the Region undertook the Operational Review Study that included the development of an operational model with the goal of developing an analytical tool to be used in developing operational and long term strategies.

The primary function of the operational model is to simulate the behaviour Of the collection system and treatment facilities. The model will also have ancillary data management, user interface and data analysis functions. XP-SWMM program was selected as the collection system model and the GPS-X program to model the treatment plant process. The objective of the chapter is to describe the steps taken to develop, calibrate and apply an operation model in the Region of Ottawa-Carleton. An overview of the model selection process is presented, however, the main focus is on the definition of the collection system, development of hydrologic parameters for summer, spring and snowmelt conditions, the calibration process, and the application of the operational model to evaluate various overflow control measures and operational changes to the collection system.
