Septic Systems – OVERVIEW

Most of Ontario’s waterfront property owners rely on on-site wastewater treatment systems to manage our household water. Understanding how our systems work and the importance of maintaining them is important to protect our lakes and rivers from contaminants. View the links below for more information.


New – March 2018 – FOCA has released a video about Cottage Country Septic Systems, including an overview about the parts of a septic system, maintenance tips, signs of trouble and more! Scroll down this webpage to view the video, or click here:  https://www.youtube.com/watch?v=5VeTGVnkYA4

Also, watch video of Rick Esselment of OOWA speaking at the June 2018 Hastings Highlands event, Poop Talk & Aliens, on the subject of Septic Systems: the good, the bad and the ugly (video, 1 hour). This video was made possible by a cooperative effort of Hastings Highlands Council and Interlake Group.


UPDATE:  To FOCA’s great disappointment, and despite a compelling case laid out for a better maintenance regime for on-site sewage systems made through the Environmental Commissioner of Ontario (see “Feb. 23” below), both the Ministry of Environment and Climate Change (MOECC), and the Ministry of Housing (MMAH) have stuck to the status quo.

In the MOECC response, they countered that high priority risks from sewage were already being addressed through the Clean Water Act (which only considers municipal drinking water sources) and that, through the existing Building Code, local municipalities were empowered to undertake further measures. In reality, this happens unevenly, with poorly understood results.

The MMAH response referenced the fact that the OBC Part 8 had just recently (2016-17) been reviewed by a technical committee, and they reiterated that during this review they made a political decision NOT to mandate a tank pump out. They also took no interest in any related provisions such as requiring record-keeping or other maintenance obligations.

Continued: February 23, 2018 – Having long been concerned about the inadequacy of the Ontario Building Code to deal with Maintenance and Management of onsite sewage systems (septic systems), FOCA, along with the Ontario Onsite Wastewater Association (OOWA) has filed a Request for Review with the Environmental Commissioner of Ontario.


July 2017 – No mandatory pump outs, inspections being included in the revised (2019) Ontario Building Code.  “The Ministry will not be moving forward with the proposals put forth in Phase One of the Building Code consultation which would have required regular inspections, pumping out of septic tanks and keeping of the septic tanks and treatment units’ maintenance records .” For a more complete description of the background and the process to make this decision, please see this article in the Summer 2017 edition of the OOWA magazine.
