Sanitary Plumbing and Drainage Pipe Sizing: Phase 2
Australian Building Codes Board
This report considers the research conducted previously on the current methods for sizing sanitary plumbing and drainage systems used within Australia and takes into account industry observations to propose improvements to these methods. The goal of this report is to draw on the work done within the industry to date and further progress the Verification Method modifications proposed for the National Construction Code (NCC) Volume Three (Vol 3), Plumbing Code of Australia (PCA) due to be released in 2025. The modifications would allow for a more seamless and robust adoption of the previously proposed methods that have a proven scientific backing and could be modified to suit different building types, fixtures and system configurations, with the current day Australian Standard (AS) design guidance.
