CSA B184 SERIES-17

Preface:

This is the second edition of the CSA B184 Series of Standards, Polymeric subsurface stormwater management structures. It supersedes the first edition, published in 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:

• removal of thermal stability and brittleness temperature;
• addition of average wall thickness to physical properties of PE and PP chambers; and
• updating table for physical properties of PP chambers.
CSA Group acknowledges that the development of these Standards was made possible, in part, by the financial support of Advanced Drainage Systems, Cultec, DI Labs Inc., and IPEX.

B184.0-17 - 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 (nonmandatory) 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.
