1-C Separate Pipelines for Sewage and Stormwater.mp4
The City of London Ontario has a well-documented history of flooding dating back to the 1700s [1]. The most destructive flood occurred in 1937 with both losses of life and property.
Currently, London’s flood plain (Timeline) 250 UTRCA has a 75% risk increase when compared to the past flood plain due to urbanization and climate change. At the Springbank and Wonderland intersection, there is a 70% increase in risk as a result of the Greenway Pollution Control Plant [2].
The problem is that **during wet weather there is a large amount of rainfall overloading the Greenway PCP**. **This leads to untreated sewage being released into the Thames Valley River causing pollution.**
