Legal Notice for Standards

Canadian Standards Association (operating as “CSA Group”) develops standards through a consensus standards development process approved by the Standards Council of Canada. This process brings together volunteers representing varied viewpoints and interests to achieve consensus and develop a standard. Although CSA Group administers the process and establishes rules to promote fairness in achieving consensus, it does not independently test, evaluate, or verify the content of standards.

  B184 Series-17 Polymeric subsurface stormwater management structures

  
  

  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.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

These Standards were prepared by the Technical Committee on Stormwater Structures, under the jurisdiction of the Strategic Steering Committee on Water Management Products, Materials, and Systems, and have been formally approved by the Technical Committee.

Notes:

1. Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2. Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3. This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

4. To submit a request for interpretation of this Standard, please send the following information to

   inquiries@csagroup.org and include “Request for interpretation” in the subject line:

   1. define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

   2. provide an explanation of circumstances surrounding the actual field condition; and

   3. where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

      Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.csa.ca.

5. This Standard is subject to review within five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to inquiries@csagroup.org and include “Proposal for change” in the subject line:

   1. Standard designation (number);

   2. relevant clause, table, and/or figure number;

   3. wording of the proposed change; and

   4. rationale for the change.

B184.0-17

General requirements and methods of testing for polymeric subsurface stormwater management structures

0 Introduction

0.1

In undeveloped areas, rainwater is intercepted by vegetation and held in natural depressions and can

be absorbed directly into the ground on which it falls. When an area is developed, buildings and parking areas cover the natural absorption areas where the rain would normally be infiltrated back into the ground. These impervious structures alter the typical absorption pattern. As a result, when the rain is not allowed to penetrate the ground it begins to accumulate and can cause ponding or flooding or flow to another location. Some consequences of flooding are as follows:

1. on roads: collisions, washouts, and traffic delays;

2. with buildings: structural and property damage, sewer backups, foundation settlement, and devaluation of property values;

3. environmental damage;

4. utility service interruptions;

5. creation of health hazards;

6. clean-up costs and increased insurance costs; and

7. personal inconvenience.

0.2

Subsurface stormwater structures are used in the collection, detention, retention, and infiltration of stormwater runoff. Structures can have configurations that include, but are not limited to, beds or trenches of various sizes or shapes designed to fit on most sites and offset the impact of impervious structures that cover natural absorption areas.

1 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;
