South East Queensland water grid

The Queensland Government’s $6.9 billion South East Queensland (SEQ) Water Grid is the most ambitious water supply project and largest urban drought response in Australia. It was built as a strategic response to the worst drought in modern history. Providing unprecedented water security for South East Queensland, the SEQ Water Grid integrates our existing water sources with new climate resilient water supplies, such as desalination and purified recycled water.

As an integrated treated water supply network, the SEQ Water Grid connects our water supplies, storages and treatment plants across South East Queensland, from Noosa to Coolangatta and out to the Lockyer Valley. It comprises a network of treatment facilities and two-way pipes that move treated drinking water from new and existing sources across the region.

As a result of the establishment of the SEQ Water Grid, South East Queensland now leads Australia in water security. This means that regardless of weather patterns, the Queensland Government has not left our future water supply to chance.

A key component of the water grid is a cluster of projects to increase water security in the Logan and Scenic Rim communities.
