scope:

This Standard sets out the minimum design and material requirements, manufacturing practices, and markings for prefabricated septic tanks, sewage holding tanks, and effluent chambers of steel, concrete, fibreglass-reinforced plastic, or polyethylene construction designed to handle sewage or sewage effluent.

This Standard does not purport to address all the safety concerns associated with the use of this Standard. It is, therefore, the responsibility of the user of this Standard to establish appropriate safety and health practices and determine the applicability of any regulatory limitations prior to use. This Standard does not apply to sewage holding tanks used in recreational vehicles; for these reference should be made to CSA Standard B45.6.

Appendix A shows typical layouts and terms used for septic tanks. The drawings are not intended to suggest materials, methods, or design criteria
