Water security is one of the most critical infrastructure challenges facing regional Australia. When Orange City Council and Central Tablelands Water joined forces to future-proof their water network, they needed a pipeline supplier with the product range, logistical capability, and national reach to deliver. Viadux stepped up — managing a complex, multi-modal supply solution across 60 kilometres of NSW's Central Tablelands.
About the Central Tablelands Regional Water Security Project
The Central Tablelands Regional Water Security Project was a significant collaborative infrastructure investment between Orange City Council and Central Tablelands Water. Following a completed preliminary design and a secured government grant, Stage 1 of the project was confirmed — covering the construction of a potable pipeline stretching from Orange to Blayney.
The full project scope encompassed:
-
60 kilometres of potable pipeline and associated infrastructure, running from Orange through to the Carcoar Filtration Plant, via Orange Airport, Spring Hill, Milthorpe, Blayney, and Carcoar
-
Bi-directional pumping stations capable of managing water transfers in either direction across the network
-
A sewer rising main from Spring Hill to Orange
-
Establishment of a pressure-boosted zone in East Orange
-
Replacement of the ageing pipeline corridor from Carcoar through to Blayney and Milthorpe
The scale and complexity of this project demanded a supplier that could coordinate product delivery across multiple modes of transport — without disrupting the project timeline or inflating costs.
The Supply Chain Challenge
Projects of this scale don't just require great products. They require precision logistics. With 60 kilometres of pipeline to supply across regional NSW, standard delivery approaches were never going to be sufficient.
Viadux developed a unique multi-modal supply chain solution combining sea, rail, and road freight to move product efficiently to the construction corridor. This approach allowed Viadux to respond quickly to changing contractor requirements on the ground while minimising transport costs for the asset owners — a direct saving that benefits ratepayers and project budgets alike.
It's the kind of logistical problem-solving that sets Viadux apart as Australia's leading distributor of ductile iron pipe and water infrastructure products. With a national branch network and deep supplier relationships, Viadux has the capability to mobilise at scale when regional projects demand it.
Why Ductile Iron Pipe Was the Right Choice
For a project of this nature — long-distance potable water transmission, bi-directional pressure management, and long service life expectations — ductile iron pipe is consistently the material of choice for water authorities across Australia.
Ductile iron offers:
-
Superior pressure performance across a range of pressure classes
-
Exceptional longevity with design service lives exceeding 100 years
-
Resistance to external loads and soil movement in regional terrain
-
Compatibility with a full range of fittings and jointing systems, including Viadux's TYTON jointing systems for faster, more reliable connections in the field
For transmission pipelines supplying critical community infrastructure — including an international airport and residential growth areas — there is simply no substitute for the performance and reliability of ductile iron.
What This Project Delivers for the Region
The Central Tablelands Regional Water Security Project is not just a pipeline. It is a long-term investment in the resilience of water supply for thousands of residents, businesses, and facilities across the region.
The completed works deliver:
Emergency water access. Orange City Council and Central Tablelands Water now have access to emergency water supply in the event of a catastrophic system failure — such as a fire at the water filtration plant. This redundancy is fundamental to modern water authority risk management.
Water security for Orange Airport and Spring Hill. The pipeline corridor ensures both water quantity and quality can be guaranteed to Orange Airport and the Spring Hill growth area, supporting economic activity and residential development.
Operational cost reduction. By effectively replacing the Carcoar to Blayney and Milthorpe pipeline corridor, the project creates the opportunity to temporarily mothball the Blayney water filtration plant — directly reducing water production costs for Central Tablelands Water and the communities it serves.
Future-proofed capacity. The infrastructure has been designed to cater for future regional growth, ensuring the network is not just fit for today's demand but built to support the communities of tomorrow.
Viadux's Role in Australia's Water Infrastructure
The Central Tablelands project is one example of how Viadux partners with water authorities, civil contractors, and councils across Australia to deliver major pipeline infrastructure on time and on budget.
Australia's water infrastructure sector is facing a period of unprecedented investment. With over 180 National Water Grid projects currently underway and Sydney Water alone managing a $34 billion infrastructure pipeline, the demand for reliable, experienced pipeline suppliers has never been greater.
- Viadux brings three key strengths to every major project:
-
-
Product depth. From ductile iron pipe and GRP systems through to valves, fittings, and repair and jointing products, Viadux stocks the full range required for complex water infrastructure projects.
-
Logistical capability. With eight branches across Australia and a national distribution network, Viadux can coordinate delivery to regional construction sites efficiently — including multi-modal solutions for large-volume, remote-access projects like Central Tablelands.
-
Technical expertise. Viadux's team understands the specification requirements of Australian water authorities, the performance demands of long-distance potable transmission, and the compliance standards that govern infrastructure investment in the public sector.
