Existing Use

If the record of your sewage system is not available and if there is an increase in the sewage flow, it will be assumed that the system is not up to Code and a new system will be required.

Alternatively, the applicant may engage the services of an engineer (with a BCIN number) to conduct a study on the sewage system for which a permit does not exist. If the system is found to meet all the requirements of the Ontario Building Code, the existing system may be accepted. Please contact your Sewage System Inspector to discuss further.

A decrease in the "performance level" beyond the capacity of any component in the system would require compensating construction (upgrading).
