Maintenance

TV Inspection

To ensure that the City’s sewer and stormwater systems are in good working condition,  Collection Systems Division staff periodically televise  these underground pipes. Our Closed Circuit TV (CCTV) Inspection Van is equipped with the latest state-of-the-art technologies enabling us to seamlessly incorporate daily inspection activities directly into our Geographic Information System (GIS).  Every single manhole, catch basin and pipe has a unique identifier with associated attributes that allows us to efficiently maintain our sewer and stormwater system assets.

Pipe Cleaning

The Collection Systems Division also routinely cleans pipes and associated structures to ensure their proper functioning. Our combination hydraulic cleaner and vacuum unit uses a powerful jet spray to convey pipe sediments to down-stream manholes and catch basins where it is then removed with a powerful vacuum hose. During each cleaning event, Collection Systems Division staff also gather information on infrastructure conditions using a handheld GPS unit. This data is then incorporated into our GIS system enabling more efficient and timely asset management.

Construction Program

In close conjunction with our CCTV inspection and pipe cleaning programs, the Collection Systems Division also repairs and replaces portions of the sewer and stormwater systems to ensure their proper functioning. Additionally, we install stormwater treatment systems in the public right-of-way to reduce the stormwater runoff impacts on local surface waters. To accomplish these tasks, our highly skilled construction crew has a full complement of heavy excavation equipment at their disposal.
