Options for Onsite Residential Wastewater Treatment Technologies
The Ontario Building Code (OBC) implemented changes to the requirements for Treatment Units as outlined in Article 220.127.116.11, which took effect January 1, 2017. These changes include the removal of Supplementary Standard SB-5 for Approved Treatment Units, and a new reference to the CAN/BNQ 3680-600 standard for certification of treatment units. Follow the links below to find details on the treatment technologies that have been certified under this standard. In addition to these treatment units, there are other systems that have been approved under the Building Materials Evaluation Commission (BMEC- a regulatory agency under the Ontario Building Code) that are also listed below.
