Narangba Sewerage Transport System (NSTS)
The Narangba Sewerage Transport System (NSTS) is a major Unitywater infrastructure project designed to support significant population growth across the City of Moreton Bay. The project expands and upgrades the existing sewer network to service emerging communities including Morayfield South, Burpengary East, Narangba East, and Pine Valley.
The system comprises a network of pump stations, rising mains, and gravity sewers conveying flows to the Burpengary East Sewage Treatment Plant. The works include new pipeline infrastructure, pump station upgrades, and network augmentation to address capacity constraints in the existing system

Scope
The NSTS project involves the design and construction of a major sewer transport network upgrade, including:
- Upgrade and construction of multiple pump stations
- Approximately 9km of sewer rising mains (up to DN1000)
- Gravity sewer installation across key sections of the network
- Auger boring and trenchless crossings at critical road and service interfaces
- Installation of valves, manholes, and associated infrastructure
The trenched installation package includes approximately 3.8km of sewer rising mains and multiple auger bore crossings along key corridors including Mackie Road, Old Gympie Road, and Pitt Road.
Works involve excavation, dewatering, traffic management, pipe installation, and reinstatement within constrained urban and transport corridors.
Service Provided
Civil Project Partners provided detailed cost estimating services to support the tender phase of the project.
This included development of cost estimates for complex pipeline installation works, incorporating trenching, trenchless construction methodologies, pump station interfaces, and associated risks such as traffic management, ground conditions, and utility constraints.
CPP also supported methodology reviews and scope definition to ensure accurate pricing and alignment with project requirements.
