Natural Capital Built for Long-Term Value

To enable sustainable, large-scale irrigation using coal seam gas (CSG) water, this client required both rigorous technical assessment of candidate land and a well-prepared regulatory submission for a beneficial use approval. The project had to address marginal soils in a region with limited experience in intensive irrigation, while aligning with environmental safeguards and regulatory expectations. 

This client sought an innovative, sustainable, and community-aligned solution for the beneficial reuse of A-grade effluent from a Sewage Treatment Plant, located just 10 km upstream of a major drinking water supply dam. Rather than pursuing a conventional advanced treatment facility, Verterra delivered an award-winning, nature-based solution.

In regions of Australia where rainfall is unreliable, treated wastewater (effluent) is increasingly recognised as a valuable resource—particularly for irrigating tree crops and other vegetation. However, to safely and effectively reuse effluent for irrigation, its quality must be carefully monitored and managed. This case study demonstrates how Verterra approached successfully undertook risk assessment and development of a management plan that would enable its beneficial reuse for a forest plantation.

The project focussed specifically on improving water quality from cane and banana farms in the Tully and Johnstone River Catchments.

Verterra’s largest project to date, providing a novel solution to water quality improvement that combines grazing improvement with ecosystem service market opportunities such as carbon farming and reef credits administered through 3rd parties.

Verterra developed the Grazing Land Management (GLM) Reef Credit Methodology in collaboration with AgriProve and GreenCollar. The Method allows farmers to generate Reef Credits and generate an alternative income stream by improving grazing practices and reducing fine sediment runoff, a critical step in protecting the Great Barrier Reef.
