West Dapto Sewer Pipeline

Supplying the Backbone of the Network

Empire supplied 3,628 metres of CW-GRP open trench pipe ranging from DN450 to DN750, specified to SN10,000 and SN20,000, PN1, complete with manhole connectors and couplers for efficient installation. An additional 310 metres of DN750 (OD820) CW-GRP jacking pipe with stainless steel collars were delivered for gravity sewer sections requiring trenchless construction.

"West Dapto highlights how the right material selection supports both construction efficiency and long-term network reliability." Aaron Mackley, Director of Sales & Operations, Empire Infrastructure

Materials Designed to Perform Long Term

The combination of open trench and jacking solutions allowed flexibility across varying site conditions while maintaining construction efficiency. GRP was selected for its corrosion resistance, high strength-to-weight ratio, and durability in aggressive wastewater environments. All CW-GRP pipes were manufactured at a our manufacturing partner facility in full compliance with ISO and Australian Standards.
