PrefaceThis is the ninth edition of CSA B66, Design, material, and manufacturing requirements for prefabricated septic tanks and sewage holding tanks. It supersedes the previous editions, published in 2016, 2010, 2005, 2000, 1990, 1985, 1979, and 1975.Major changes to this edition includea) new requirements for reaction-injection moulded thermoset tanks;b) new requirements for compression-moulded thermoplastic tanks;c) revision to riser requirements;d) revision to compartmentalization requirements;e) clarification and a new requirement for tanks assessed only for structural integrity and water tightness;f) revision and new requirements for resins used for fibreglass-reinforced polyester tanks;g) revision to vacuum test requirements; andh) revision to top-loading test requirements. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope1.1 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 a) steel; b) concrete; c) fibreglass-reinforced plastic (FRP); d) reaction-injection moulded thermosets; and e) polyvinylchloride (PVC), polypropylene (PP), polyethylene (PE), or other thermoplastics that are designed to handle sewage or sewage effluent.1.2 This Standard includes criteria for assessing other tanks used in sewage systems for structural integrity and watertightness, such as a) tanks used for wastewater treatment plants; b) tanks used as pretreatment tanks; c) pre-aeration tanks; d) sewage flow-equalization tanks; and e) tanks used for pit privies.1.3 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 CSA B45.6.1.5 In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
