PE Pipework Now Accepted for Water Supply

As of December 2024 the SEQ Code Civil Infrastructure Products and Materials list (IPAM) has been updated to reflect the use of PE (polyethylene) pipework and fittings for the City’s water supply network (previously only approved for use when directional drilling). Developers are encouraged to consider this pipe material for use in new subdivisions and for connections in brownfield/infill areas within the City.

Key Information

• PE pipework is the City’s preference for extensions (such as subdivisions) or new connections to our water network.
• The latest version of the IPAM list is available on the SEQ Code website - SEQ Code Products List.
• For PE water mains or connections on the Gold Coast, refer to the SEQ Code Water Supply Standard drawings endorsed by the City (CoGC).
• The City prefers butt welded joints for PE construction, minimising the use of electrofusion (EF) couplings. Where EF couplings are necessary (e.g., for live connections after pressure testing), they should be placed in accessible verge areas, not under road pavements. EF coupling locations need not be specified in designs, as the City’s Contributed Assets team will coordinate with engineering consultants on-site.
• All valves installed on PE water mains are to be restrained as per SEQ Code requirements.
• PE pipework is permitted for watermains in carriageways, and for industrial and commercial areas. SDR11 pipework will typically be acceptable for these use cases.
