The remote location of Etta Plains presented significant logistical challenges for manufacturing, transporting and installing large-scale irrigation infrastructure. The development also required a completely new approach to water control, with existing products unable to efficiently manage the large flows and irrigation bay sizes planned for the project.

The initial stages involved approximately six months of collaborative design work between Padman, the project owners and engineering partners. 

This process resulted in the development of several new products and innovations, including: 

• PE3000 Water Control Structure 

• MaxiFlow 2000 Structures 

• Hybrid Headwall System 

• Custom Rolled Downstream Bubbler Sills 

These solutions were specifically developed to manage the project’s exceptionally high flow requirements while minimising erosion and improving long-term performance.

• Etta Plains ownership and management team 

• RSA Contractors (Dalby) 

• Searle Plumbing (Julia Creek) 

• JF Power Freight 

• Peter Lesson Designs 

• Padman Water Solutions

Etta Plains involved every part of the Padman Group, including design, engineering, manufacturing, project management and installation support.

The project also played a major role in validating the formation of Padman Water Solutions and the establishment of the Ayr manufacturing facility in North Queensland, providing a commercially viable freight solution for remote irrigation developments throughout the region.

The first stage of construction was completed under extreme North Queensland conditions, with temperatures exceeding 46°C. 

Working alongside the property owner, RSA Contractors and a small onsite crew, the team delivered the first three 200-hectare irrigation paddocks over approximately six weeks. Development has continued progressively since then, with approximately 1,000 hectares and around 700 tonnes of precast concrete infrastructure being added each year. 

Beyond agricultural production, the project has delivered significant environmental benefits. The new storages and water infrastructure have created valuable aquatic habitats, attracting birdlife and native water species that were previously uncommon in the area.
