NUFLOW NORTHWEST SYDNEY
RIVERSTONE SWIMMING CENTRE | BLACKTOWN CITY COUNCIL
PROJECT OVERVIEW
Nuflow was engaged to rehabilitate a 300mm steel and asbestos cement (AC) pipe within
the plant room of Riverstone Swimming Pool. The pipe, which was concrete-encased and servicing the main pool system, had deteriorated and required a trenchless solution to avoid costly and disruptive demolition. The project involved custom liner fabrication, flange reconstruction, and precise reassembly of fittings to restore the system to full operational capacity.
CHALLENGE
- Confined plant room environment – The pipe was located within a concrete-encased section of the plant room, creating restricted access and making traditional replacement unfeasible.
- Complex fittings and disassembly – Rehabilitation required unbolting and removing a 300mm elbow and PVC spacer, then reinstating them after relining.
- Custom flange and liner requirements – A stub flange needed to be re-created using custom-made liners, with trimming, drilling, and alignment works required to ensure a perfect fit.
- Post-installation pressurisation – Final re- pressurisation of the line was to be carried out by Blacktown Council, with allowances for potential bolt and fitting adjustments noted as an additional charge.
THE SOLUTION
To deliver a tailored trenchless rehabilitation, the Nuflow team implemented a staged approach:
THE RESULTS
The 300mm AC and steel pipe within the Riverstone Swimming Pool plant room was successfully
rehabilitated using Nuflow’s Blueline technology. Through the creation of custom liners, stub flange fabrication, and precise reassembly of fittings, the project restored the system’s integrity without invasive demolition. The works were delivered across multiple stages to ensure accuracy and compliance, while coordination with Blacktown Council provided a seamless handover for re-pressurisation. This trenchless approach minimised disruption, preserved the plant room structure, and extended the service life of critical infrastructure within the public swimming facility.
