When local catchments cannot keep up with demand, a region ends up leaning on emergency measures. In south-west Victoria that meant drought relief bores and water restrictions. Wannon Water's answer was the Hamilton-Grampians pipeline: a 52 km main from Balmoral to Cavendish that connects the Hamilton system to Rocklands Reservoir. Viadux supplied TYTON DN375 PN20 ductile iron pipe and SUREFLOW fittings as Pipe and Fittings Supply Contractor, with deliveries completed in June 2010. The completed pipeline delivers up to 2,000 megalitres (two billion litres) of water a year to the Hamilton system.

The Problem: Demand Outgrowing the Local Catchment
Demand for water in the region had grown beyond what local catchment areas could supply. To fill the gap, the community had come to depend on emergency drought relief bores and water restrictions, neither of which is a lasting answer.
Wannon Water also faced a longer horizon. Significant growth was predicted over the next 50 years, so the Hamilton-Grampians pipeline had to meet present needs and leave room for what the region would need later.
How the Hamilton-Grampians Pipeline Was Supplied
Viadux worked with Wannon Water to specify pipeline products that would meet both present and future community needs. The result was TYTON DN375 PN20 ductile iron pipe for the main, matched with SUREFLOW fittings including bends, tees, and valves.
Ductile iron pressure pipe for Australian water networks is manufactured to AS/NZS 2280. You can browse the range on the Viadux ductile iron pipe pages, including ductile iron water products and the SUREFLOWbrand.
Before and After the Pipeline
• Water Source: Before, the region relied on local catchments that were short of demand. After, the system has a direct connection to Rocklands Reservoir.
• Emergency Measures: Before, there was a dependence on drought relief bores and water restrictions. After, these issues are addressed by the new supply.
• Supply to the Hamilton System: Before, supply was limited by the local catchment. After, the pipeline delivers up to 2,000 ML (two billion litres) a year.
Wannon Water's Hamilton Pipeline: What Was Delivered, Step by Step
1. Specification: Viadux collaborated with Wannon Water to specify products for present and future community needs.
2. Pipe Supply: TYTON DN375 PN20 ductile iron pipe for the 52 km route from Balmoral to Cavendish.
3. Fittings Supply: SUREFLOW bends, tees, and valves to complete the pipeline.
4. Delivery: Pipe and fittings deliveries were completed in June 2010.
5. Completion: The project finished on time and under budget.

Hamilton Water Supply Outcome: Up to Two Billion Litres a Year
The Hamilton-Grampians pipeline delivers up to 2,000 ML (two billion litres) of water each year to the Hamilton system. It was completed on time and under budget, which the case study presents as a benefit of working with an experienced pipeline solutions provider.
If you are comparing regional pipeline projects, the Viadux Goldenfields Water County Council and Eyre Peninsula Pipeline case studies show how ductile iron pipe was used in New South Wales and South Australia. More civil, industrial and irrigation projects are listed on the Viadux case studiespage.
What This Means for Other Regional Pipelines
The Hamilton-Grampians project shows why long-term demand belongs in the specification from day one. When a region expects significant growth over several decades, a few questions are worth asking before products are chosen:
• How much water does the region need now, and how much is predicted over the next 50 years?
• Is the region relying on emergency measures such as drought relief bores or restrictions to fill the gap today?
• Can the pipe, fittings, and valves be supplied together so they are specified to work as one system?
• Is the supplier involved early enough to help with the specification, not only the delivery?
On this project, answering those questions early led to a clear scope: one pipe size and pressure class for the main, matched fittings, and a delivery program that finished on time and under budget.
