SA Water engages Geofabrics to Upgrade Infrastructure with PVC-Elvaloy Liners
with the aim of delivering an additional 12 GL per year of recycled water for irrigation. Phase 2 was to construct recycled water storage infrastructure to the area north of the Gawler River, enabling a new major irrigation area to be built. The recycled water storage included two 200 megalitre earth bank storage ponds. The pond’s storage capacity was designed to cater to future growth in the area, for at least the next twenty years.  The improved performance is largely due to the Dupont Elvaloy® technology, which enables protection against weathering and UV resistance, whilst allowing the PVC alloy to maintain it’s flexibility.
