Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.

Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Web Shop at www.standards.com.au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue.

Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization.

We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover.

This Standard was issued in draft form for comment as DR 03198.

PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee WS-020, Stormwater, to supersede AS/NZS 3500.3—1998, National Plumbing and Drainage, Part 3.2: Stormwater drainage—Acceptable solution.

Amendment No. 1 (July 2006) is attached at the end of the document.

The objective of this Standard is to provide installers with solutions to comply with—

(a) the Plumbing Code of Australia (PCA);

(b) the Building Code of Australia (BCA); and

(c) the Building Code of New Zealand for stormwater drainage.

This Standard is part of a series for plumbing and drainage, as follows:

AS/NZS

3500 Plumbing and drainage

3500.0 Part 0: Glossary of terms

3500.1 Part 1: Water services.

3500.2 Part 2: Sanitary plumbing and drainage systems

3500.3 Part 3: Stormwater drainage systems (this Standard)

3500.4 Part 4: Heated water services.

3500.5 Part 5: Domestic installations

This revision includes the following changes:

(i) Changes in the context to enable this Standard to be referenced in the above listed Codes.

(ii) The inclusion of revised clauses to bring them into line with the provisions of the Plumbing Code of Australia.

(ii) Revision of the materials and products used in stormwater drainage systems.

(iii) Incorporation of Amendment 1 and RUL PL.13—2002.

(iv) Revised examples in Appendix H.

Other changes incorporate amendments and additions arising from industry recommendations which include—

(a) changes in limitations in FRC pipes and epoxy resins; and

(b) clarification of examples for design of eaves gutters of slope less than 1:500.

This Standard does not cover the criteria for soakers and siphonic systems. Sufficient data was not available in these areas at the time of publication. These areas will be included in a future edition of this Standard, subject to additional research and investigation being carried out.

The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance.

Statements expressed in mandatory terms in notes to figures and tables are deemed to be requirements of this Standard.

PROVISION FOR REVISION

This Standard necessarily deals with existing conditions, but is not intended to discourage innovation or to exclude materials, equipment and methods, which may be developed in future. Revisions will be made from time to time in view of such developments and amendments to this edition will be made only when absolutely necessary.
