It’s been a busy few months at the BIGG Lined Catchment project site in Flaxman Valley with works nearing completion.
This project demonstrates how lined catchments can be effectively constructed and integrated with existing farm infrastructure to harvest rainfall and improve water security. In this case, the 1-hectare poly-lined catchment feeds directly into an existing dam, maximising water capture during rainfall events.
Construction has involved several key stages. The site was first cleared of an old vineyard, followed by detailed earthworks to shape and smooth the surface, ensuring proper runoff and preventing water pooling. Large sheets of poly lining were then rolled out and welded together to form a continuous surface across the catchment. Tyres have been strategically placed to secure the liner, and fencing has been installed to protect the area from livestock and wildlife.
A video showcasing the construction process is currently in production, offering a step-by-step look at how the system was built. BIGG also plans to host a field day at the site soon—keep an eye out for event details.
This project has been made possible through funding from the South Australian Drought Resilience Adoption and Innovation Hub (via the Australian Government’s Future Drought Fund) and the Northern and Yorke Landscape Board through the Landscape Priorities Fund.
