O'Dea Avenue Outfall

GRP Jacking Pipe for an Inner-City Outfall

In 2018, Empire supplied 300 metres of DN700 BOSSPIPE™ Centrifugally Cast GRP (CC-GRP) Jacking Pipe. The DN700 diameter met the hydraulic requirements of the outfall within the physical constraints of the urban corridor, where trenchless installation was the only practicable methodology.

"BOSSPIPE™ CC-GRP suits the inner-city outfall environment well: structurally capable for microtunnelling, corrosion-resistant, and light enough to handle in confined jacking shafts." Aaron Mackley, Director of Sales & Operations, Empire Infrastructure

Microtunnelling Through a High-Density Precinct

Works were completed using microtunnelling beneath the active streets and development sites of the Waterloo precinct. Trenchless construction was essential to avoid surface disruption in an area with high levels of construction activity and pedestrian traffic. Empire delivered the DN700 BOSSPIPE™ CC-GRP pipe on time, supporting Rob Carr's installation sequence.

Drainage Infrastructure for a Growing Precinct

The project is one of several Empire has supported in the Green Square and Waterloo corridor, reflecting a track record supplying GRP jacking pipe for urban drainage projects. Empire coordinated supply to align with Rob Carr's construction program, ensuring the full 300-metre scope was available to match the tunnelling schedule, supporting one of Sydney's most rapidly developing areas.
