All our listed providers for building and developing must follow and use Sydney Water's current instructions, forms, and standards and specifications to fulfil all requirements for the type of work they do. The documents below are updated and replaced from time to time.
Developers need these documents to define, design, construct and commission complex works infrastructure. Complex works include wastewater pumping stations, chemical dosing units and non-gravity wastewater systems.
Please read these documents with either the relevant Water Services Association of Australia (WSAA) codes of practice and associated Sydney Water supplements or the Sydney Water editions of the WSAA codes.
Designers and constructors must only use conforming standard products and/or listed non-standard products for components that are critical for the long-term performance of our infrastructure.
These products must:
These are products we've deemed fit for purpose and/or provide equivalent functional performance to standard products. They're individually listed in the EPS 501 – List of Approved Non-Standard Products for Networks (109KB).
Deemed to Comply (DTC) drawings are approved design options that:
It isn't mandatory to use these drawings.

Providers and contractors must use these standards and specifications to design, construct, maintain or manage our infrastructure.
You must use our Sewerage flow schedule (315 KB, XLSM file) to determine wastewater (sewage) flows, pipe sizes and grades for new wastewater designs.
Providers and contractors must use the Sydney Water editions of the WSAA codes to plan, design and construct water mains, gravity wastewater mains and sewage pumping stations.
For other infrastructure, you must follow the national editions of the codes and project-specific variations. You can buy the codes from Water Services Association of Australia (WSAA).
