EXECUTIVE SUMMARY:
The purpose of this report is to award a construction contract for the replacement of aging sanitary and storm sewer mains on Gosper Crescent. The work involves pipe bursting of a sanitary and storm sewer main, each approximately 127 metres in length, associated service reconnections, drainage improvements and surface restoration.

Pipe bursting involves pulling a new pipe through the alignment of the existing sewer main while breaking apart and displacing the existing pipe. This method reduces the amount of excavation required compared to conventional open-cut construction, limiting impacts to the roadway, driveways and surrounding properties. The project also includes reconnecting existing sanitary and storm se...
