Rapid Assessment Tech Services will be starting a sanitary main lines and manhole assessment in the southeast quadrant of Caledonia (area south of the Grand River, east of Argyle St S) on Monday, November 27, 2023.

During this assessment, residents may notice a high pitch sound in the manholes, mains or internal plumbing of their home.  This is part of the assessment process and will last for a very short period.  This will not affect operation of the sanitary system.

The assessment is expected to be completed within 2 weeks.

We apologize for any inconvenience this may cause.
