Preface
This is the eighth edition of CSA B66, Design, material, and manufacturing requirements for prefabricated septic tanks and sewage holding tanks. It supersedes the previous editions, published in 2010 and 2005 under the same title, and published in 2000, 1990, 1985, 1979, and 1975 under the title Prefabricated Septic Tanks and Sewage Holding Tanks.
Major changes in this edition include
a) new requirements for the assessment of sewage tanks, other than septic tanks and holding tanks, with regard to structural sufficiency and watertightness;
b) clarification of inlet tee requirements;
c) clarification of volume–depth labelling requirements;
d) revision to chamber divider test parameters; and
e) clarification of gasket, sealant, and joint fabrication requirements.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
Scope
1.1
This Standard specifies minimum design and material requirements as well as manufacturing practices and markings for prefabricated septic tanks, sewage holding tanks, and effluent chambers made of steel, concrete, fibreglass-reinforced plastic (FRP), polyvinylchloride (PVC), polypropylene (PP), polyethylene (PE), or other thermoplastics that are designed to handle sewage or sewage effluent.
1.2
This Standard can be used to assess tanks, other than septic tanks and holding tanks, for structural sufficiency and watertightness.
Note: Other tanks used in sewage systems include, but are not limited to, the following:
a) tanks used for wastewater treatment plants;
b) tanks used as trash tanks;
c) pre-aeration tanks;
d) sewage flow-equalization tanks; and
e) tanks used for pit privies.

This Standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of any regulatory limitations before use.
1.4
This Standard does not apply to sewage holding tanks used in recreational vehicles, which are covered in CAN/CSA-B45.6.
