North East Trunk Sanitary Sewer Project

Building the Infrastructure to Shape Leamington’s Future

The Municipality of Leamington is embarking on one of the most transformational infrastructure projects in its history, a long-awaited investment that will shape how our community grows, lives, and prospers for decades to come.

In August 2025, the Ontario government announced a $41 million investment to support critical wastewater infrastructure in Leamington, specifically the construction of the North East Trunk Sanitary Sewer Line. This funding recognizes Leamington’s strategic planning, long-term vision, and readiness to grow responsibly.

Why This Project Matters

This project is about more than pipes and pavement; it is about unlocking opportunity, supporting housing, strengthening food security, and protecting the environment.

The North East Trunk Sanitary Sewer Line will extend from the Leamington Pollution Control Centre north to Mersea Road 4 and County Road 18 to the adjacent employment lands. Once complete, it will:

• Enable housing growth, supporting up to 6,500 new residential units
• Open new industrial and employment lands, attracting businesses and jobs
• Reduce reliance on septic systems, particularly for greenhouses and farmworker housing
• Support Leamington’s greenhouse sector, strengthening food security and the local economy
• Protect Lake Erie through modern, centralized wastewater management

This investment ensures that growth happens by design, not by accident, without placing an unfair burden on existing taxpayers.

This is a balanced investment that benefits residents, businesses, agriculture, and the environment alike.

A Long-Awaited Project, Years in the Making

Planning for this infrastructure dates back more than a decade, including an Environmental Assessment completed in 2013. Successive councils have made bold, forward-looking decisions to position Leamington for sustainable growth.

The Ontario government’s investment is a direct result of that work — turning planning into action.

Related Project: Seacliff Drive East Reconstruction

The Seacliff Drive East Reconstruction Project is a key component of the broader North East Trunk Sanitary Sewer initiative.

That project includes:

• New sanitary and storm sewers
• New watermain infrastructure
• Road reconstruction, sidewalks, streetlights, and a multi-use pathway

Together, these coordinated projects ensure that infrastructure is built once, efficiently, and to modern standards, minimizing future disruption while maximizing long-term value.

Construction Timeline

• Construction start: Phased construction underway
• Expected completion: 2028

Work will be carefully staged to reduce impacts while keeping the community moving.

Traffic Impacts & Road Closures

As with any major infrastructure project, temporary road closures and traffic disruptions will occur during construction.

Residents and businesses can expect:

• Localized road closures and detours
• Reduced lane access in active construction zones
• Short-term access changes to properties in affected areas

We thank residents and businesses for their patience as we build the infrastructure needed for Leamington’s future.
