Humber and Black Creek Sewage Pumping Stations Forcemain Rehab - Notice of Field Studies

The Regional Municipality of York is rehabilitating the twin sewage forcemain and chambers between the Humber Pump Station and Black Creek Pump Station, in the City of Vaughan. The rehabilitation work will extend the life of the forcemain and chambers.

A forcemain is a pressurized sewer pipe powered by sewage pumping stations that moves wastewater through our sewer system. The chambers provide safe and easy access to the sewage system.

Before the rehabilitation work begins, York Region needs to conduct multiple field studies. York Region has retained the services of an engineering consultant (GHD Limited) to conduct the field studies.

When: The field studies will be conducted between spring 2023 and fall 2024

Field studies could include:

• Topographical survey
• Inspection of the forcemain and chambers
• Geotechnical borehole drilling and monitoring well installation
• Utility surveys and ground test pits
• Inventory of the ground cover, fauna, shrubs and trees

What You Can Expect:

• A field study can take up to five days to complete
• There may be different field study crews requiring access to properties to conduct studies and collect readings at various times
• For geotechnical borehole drilling, a drill rig may be required, and a groundwater monitoring well may be installed; advance notice if a monitoring well is required will be provided. It will be removed when the project is complete.
• All the ground test pits will be restored to their original condition and every effort will be made to minimize any disturbance
• There is no impact to water services

Thank you for your patience while we complete this vital work. As with all construction projects, some work may be rescheduled due to weather or other conditions. Visit york.ca/waterconstruction for more information about water and wastewater construction projects.
