AS/NZS 3500.3:2015 Plumbing and drainage, Part 3: Stormwater drainage
Standards Australia/Standards New Zealand
Supersedes: AS/NZS 3500.3:2003 Plumbing and drainage, Part 3: Stormwater drainage
Draft Designation: DR AS/NZS 3500.3The objective of this Standard is to provide solutions to comply with—
(a) the National Construction Code; and
(b) the Building Code of New Zealand,
for stormwater drainage.
This Standard is part of a series of Standards 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
3500.3 Part 3: Stormwater drainage (this Standard)
3500.4 Part 4: Heated water services
3500.5 Part 5: Housing Installations
The objective of this revision is to ensure compliance with the ABCB protocol for referenced documents.
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.
Notes used in this Standard are of an advisory nature only and are used to give explanation or guidance to the user on recommended considerations or technical procedures, or to provide an informative cross-reference to other documents or publications. Notes to clauses in this Standard do not form a mandatory part for compliance with this Standard.
This document includes commentary on some of the clauses of the Standard. The commentary directly follows the relevant clause, is designated by ‘C’ preceding the clause number and is printed in italics in a box. The commentary is for information and guidance and does not form part of the Standard.
Some materials and products used in a stormwater drainage system are provided with instructions for installation and use. Although not a requirement of this Standard or acceptable as an alternative to the requirements of this Standard, compliance with these instructions generally ensures that—
(i) the material or product is fit for the application;
(ii) the performance of the system is not degraded;
(iii) the durability of the material or product is not impaired; and
(iv) the manufacturer’s warranty remains valid
