Bradford Urban Area Inflow and Infiltration Study

Project Description

The Project includes a review and analysis of the Bradford West Gwillimbury's (BWG) entire wastewater network. The goal of the project is to investigate and identify likely sources of inflow and infiltration within the Town's wastewater system. The ultimate goals, based on findings, will include determination of problematic areas within the Town and recommendations to mitigate these inflow and infiltration flows.

The project includes data collection and monitoring of wastewater flows within the sewer system and the creation/calibration of a wastewater model based on the data collected.

Further investigative works include fog testing of the Town’s sanitary sewers to determine specific points of inflow and or infiltration (groundwater or storm water entering sanitary sewers).

​Fog Testing of Sanitary Sewer Works

The Town and its Consultant are currently conducting fog testing of sanitary sewers within BWG’s urban boundaries from now until June. We are completing fog testing to find potential points where storm water enters sanitary sewers, resulting in higher risks of basement flooding and increased wastewater treatment costs.

Schedule

This schedule is tentative and can change based on weather and other external factors. The project team will update the schedule as required.

Please note: although it is not at all harmful, fog may enter your home during our testing if a leak is present. You will be contacted by staff in the event that a leak is detected. A video is provided below to illustrate what you may see in the event of a leak.

Please view the FAQ at the end of this webpage for a general understanding of the works that are taking place.
