Preface
This is the third edition of the CSA B184 Series of Standards, Polymeric subsurface stormwater management structures. It supersedes the previous editions published in 2017 and 2011.
This Series consists of the following Standards:
• B184.0, General requirements and methods of testing for polymeric subsurface stormwater management structures;
• B184.1, Polyethylene (PE) chambers; and
• B184.2, Polypropylene (PP) chambers.
The changes to this edition include the following:
• addition of PE thermoformed chambers;
• additional chamber sizes;
• addition of the oxidation induction time test;
• replacement of AASHTO LRFD Bridge Design Specifications with ASTM F2787 for structural design;
• clarification of intended voids or cells in closed-cell cellular structures;
• clarification of wall thickness measurements;
• update to marking requirements; and
• addition of Annex G for performance qualification and in-plant quality control of the internal cellular structure of profile walls.
These Standards were prepared by the Technical Committee on Stormwater Structures, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and have been formally approved by the Technical Committee.
These Standards have been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. They have been published as National Standards of Canada by CSA Group.
These Standards are considered suitable for use for conformity assessment within the stated scope of the Standard.

CSA B184.0:22 - General requirements and methods of testing for polymeric subsurface stormwater management structures
Scope
1.1
This Standard covers polymeric subsurface stormwater management structures and accessories used in the collection, detention, retention, and infiltration of stormwater runoff. Applications include, but are not limited to, commercial, municipal, residential, agricultural, industrial, recreational, and highway drainage.
Note: In the CSA B184 Series, polymeric subsurface stormwater management structures are also referred to as stormwater structures.
1.2
This Standard specifies requirements for
a) materials and manufacture;
b) design and structural integrity;
c) durability and longevity; and
d) storage capacities and tolerances.
Notes:
1) Annex B specifies requirements pertaining to the roles and responsibilities of the parties involved in the design and construction of stormwater management systems.
2) The following Annexes provide additional guidance:
a) Annex C on installation of chambers;
b) Annex D on commissioning of stormwater management systems;
c) Annex E on operation and maintenance of stormwater management systems; and
d) Annex F on performance qualification and in-plant quality control.
1.3
This Standard is intended to be used with CSA B184.1 or CSA B184.2 to form a complete set of requirements for a particular product.
1.4
The current edition of the CSA B184 Series covers chambers only (i.e., arch-shaped stormwater management structures).
Note: Other types of structures (e.g., box-like structures and crates) will be considered for future editions.
1.5
This Standard does not cover
a) structures for applications such as
i) septic sewage and sanitary waste systems;
ii) above-ground stormwater management systems;
iii) chemical spill containment;
iv) wastewater containment;
v) water harvesting;
vi) irrigation systems; or
vii) management of liquids other than stormwater; and
b) piping systems.
1.6
In these Standards, 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.
1.7
The values given in SI units are the units of record for the purposes of these Standards. The values given in parentheses are for information and comparison only.
