How can a sewage system inspector check the OBC’s requirements?
The OBC requires that septic tanks conform with the requirements of CSA Standard CAN3- B66 — Prefabrication Septic Tanks and Sanitary Sewage Holding Tanks. This standard requires that certain information be marked on the tank. In addition, building officials can request that certain tests be completed or documents provided to satisfy themselves that tanks conform with the OBC requirement and CSA standard.
