Installation and Modifications of Septic Systems

Since July 2014, the Municipality of Dysart et al has administered Part 8 of the Ontario Building Code in house. Municipal Building and Septic Inspection staff have been trained and certified and have successfully managed this new part of their portfolio for the past few years.


Part 8 of the Ontario Building Code governs sizing requirements and setback information regarding all classifications of on-site sewage systems. We have created a Quick Reference Sheet to assist with designing septic systems. Please bear in mind that Sewage Systems should be designed and installed by qualified professionals, with the exception of homeowners.

Sewage System Review

According to the OBC, any time there is an alteration to a dwelling which includes an added plumbing fixture, an additional bedroom or an increase in living space of 15% or more, the property is subject to a septic review. Please fill in our Septic Review Application for Existing Septic Systems. Please note that included in the review process is a required site visit during which a municipal inspector will need access into the dwelling and/or accessory buildings.

Septic System Maintenance
There are many components to a septic system and not everybody is well versed in the technology and how it all works. Please reference the recommended Do's and Don'ts sheet created by the Ontario Onsite Wastewater Association. We also have available, some custom fridge magnets, that remind property owners when to pump and inspect their systems to help keep it healthy.
