Real Time Control Sterling Street Sewer Chamber Construction

Project Details

The Sterling Street underground Sewer Chamber will undergo capital construction to improve control of combine sewer flows to the wastewater treatment plant. Included in the scope of work are partial and full road closures on Sterling Street between Forsyth Avenue West and Whitton Road to accommodate the excavation and replacement of the existing chamber.

Start date: April 2023 | Expected end date: February 2024

What to expect during construction

• Weekend Work: From June 17 to August 19, work will occur on Saturdays between 7 am and 7 pm.
• Beginning the week of April 10, 2023, lane restrictions will be in place between Forsyth Avenue N and Whitton Road in order to accommodate pre-construction activities.
  • During this time, vehicular traffic will be accommodated in both directions. The north sidewalk will be closed; however, the south sidewalk will remain open for pedestrians. Cyclists will be able to travel down Sterling Street but are asked to dismount and walk their bike on the south sidewalk located across from the work zone.

• On April 27, 2023, the City will fully close Sterling Street between Forsyth Avenue N and Whitton Road to vehicular traffic. This closure is expected to take place for approximately four months, wrapping up by mid-August 2023.
  • ​​During this time, pedestrian traffic will be maintained using the south sidewalk and a detour route will be established for motorists, cyclists and HSR. Cyclists wishing to travel along Sterling Street can do so but are asked to dismount and walk their bike on the sidewalk across from the work zone.

• Mid-August 2023, the City will fully reopen Sterling Street between Forsyth Avenue N and Whitton Road.
• Future work, including road restorations will be determined in late 2023 and will require temporary intermittent lane restrictions. Once details and timing are available, they will be available on this page.

Note: All dates are subject to change and are weather dependent.

Throughout construction

• Detours for motorists, pedestrians, cyclists and HSR passengers will be provided in advance of the full closure via on street signage and the City’s dedicated project
• Oakwood Place Park will be used by the contractor to accommodate temporary site trailers and parking. The park will be returned to the original state at the end of the project.
• Construction will occur Monday to Friday, between the hours of 7 am and 7 pm. Extended hours may be required and will be posted on this page if necessary.

Why we are doing this work

Real-time controls help to efficiently manage wastewater flows and reduce combined sewer overflow events. With advanced computer software responding to sensors that measure factors such as flow, level, pressure and rainfall, real-time controls manipulate gates, weirs, chambers, and pump stations to get the most out of the wastewater system. These responses and adaptations occur immediately, resulting in an overall system that is more capable of managing wet weather flows, better prepared to defend its own systems from damage or overuse and better equip us to protect the water quality of Hamilton Harbour. By upgrading flow regulator chambers as on Sterling Street, we will be able to monitor, control and capture more combined sewer flows in real time. Learn more about Real Time Control
