B185.0

1 Scope

1.1 Inclusions

This Standard applies to polymeric subsurface stormwater crates made of injection-moulded, extruded, compression-moulded, or thermoformed polymers, and specifies requirements for

a)  materials and manufacture;

b)  design and structural integrity for vehicular traffic areas, including durability and longevity;

c)  storage capacities and tolerances; and

d)  accessibility for inspection and maintenance.

Notes:

1)    In this Standard, subsurface stormwater crates are referred to as stormwater crates. In the industry, stormwater crates are also referred to as stormwater boxes.

2)    Stormwater crates, along with inspection shafts and sidewalls, are the primary elements of modular stormwater crate systems, where the different components are assembled to create a system for stormwater management.

3)    Stormwater chambers (i.e., arch-shaped stormwater management structures) are covered in the CSA B184 Series.

4)    “Stormwater” is referred to as “surface water” in ISO 6107.

5)    Informative Annex A provides information on non-structural and optional components of stormwater crate systems; informative Annex B specifies the procedure for the linearity test; informative Annex C specifies the procedure for the multi-layer compression strength test; normative Annex D specifies the production tests and in-plant quality control requirements; informative Annex E provides recommended installation and maintenance practices for stormwater crate systems; and informative Annex F provides information on self-declaration of conformity.

6)    Informative Annex G specifies a protocol for negative air pressure testing (i.e., simulating external water pressure).

1.2 Intent of this Standard

This Standard is intended to be used in conjunction with CSA B185.1 to form a complete Standard for a particular product.

1.3 Applications

Stormwater crates covered by this Standard are intended for stormwater management (i.e., detention, infiltration, and storage of stormwater) in underground applications.

Notes:

1)    Applications can include commercial, municipal, residential, agricultural, industrial, recreational, and highway drainage.

2)    The terms “detention” and “attenuation” are used interchangeably in the industry, as well as the terms “infiltration” and “retention”.

3)    Stormwater crates covered by this Standard are also used in pedestrian and landscaped areas.

1.4 Exclusions

The requirements of this Standard do not apply to

a)  non-load bearing (i.e., non-structural) components of stormwater crate systems; and

b)  rooftop crates.

1.5 Terminology

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.

1.6 Units of measure

The values given in SI units are the units of record for the purposes of this Standard.
