Sewage Collection

Sewage Collection

Sewage collection is provided to most properties in the urban area of Leamington.  Sewage is collected by means of sanitary sewers or combination sewers and transferred to the Leamington Pollution Control Centre for treatment prior to being released to Lake Erie. 

Combined Sewer Overflows

During storm events, combination sewers may reach capacity resulting in overflows to the natural environment at various overflow sites throughout the Municipality.  A summary of combined sewer overflow events for the current year, by location, is provided below and is updated following an event.  Previous year overflow events are summarized in the annual report found on the Plans, Publications, and Reports page.

 Sewer Backups & Maintenance

The combined and sanitary sewer mains and connections within the Municipal right of way are maintained and repaired by the Municipality. If you are having a problem with sewage back up at your property please contact Public Works.
 Availability
For information on the availability and operation of sanitary and combination sewers, please contact Public Works.  For information on new developments, please contact Engineering Services.
 Sewer Separation
Combination sewers are an older method of sewer construction where a single pipe carries both storm and sanitary sewage. As a result during heavy rainfall events sanitary sewage gets bypassed at various overflow sites throughout the Municipality when the flow of rain water exceeds the ability of the combined sewers to carry it away.

In an effort to capture and treat all sanitary sewage, and reduce the amount of rain water being sent through the Pollution Control Centre, the Municipality continues to separate combination sewers into sanitary sewers and storm sewers.
Sewage Collection System Reports
The Municipality is required to submit annual reports to the Ontario Ministry of the Environment, Conservation and Parks to meet the requirements of the Consolidated Linear Infrastructure Environmental Compliance Approval.  To view the most recent reports please visit the Plans, Publications, and Reports page.
