Sewerage Code Drawings

The CTM Sewerage Code is developed to be consistent with the – SEQ Water Supply & Sewerage Design & Construction Code Amendment to WSA-02 2002 V2.3. Relevant standard drawings are listed below, with a link to CTM drawings. SEQ drawings can be accessed via https://www.seqcode.com.au/seq-sewerage-code. Note that the latest versions of SEQ drawings may not be approved by CTM, have annotations to the provisions, or may have been published after the CTM Code was published and are therefore yet to be approved (denoted with a *). The following tables provide guidance on the provisions of the SEQ drawings approved in the CTM Code.
