seq Sewerage Code

The SEQ Sewerage Code has been published as a fully integrated SEQ Edition eBook, which may be purchased from the WSAA Code Shop. This version of the code has effect from 1 July 2019. It is based on the latest edition of the WSAA code and is therefore significantly different to the previous SEQ Edition, which was based on an earlier edition of the WSAA Code.

SEQ Amendments to the base WSAA code are no longer published. Whilst the standard drawings are included in the eBook, they are also published below in PDF format for your convenience. Latest news for the Sewerage Code and other codes can be found at SEQ Code news.

For an overview on products and materials commonly used in sewer design and construction, please refer to WSA 402 Product and Material Information and Guidance, which is a supplement to the Gravity Sewerage Code of Australia WSA 02-2014 and provided for information only.
