South East Queensland residents could be on mandatory water restrictions in just four months amid fears the region’s dams will struggle to supply water to the booming population.

Water Minister Glenn Butcher’s office was emailed a report last December warning about the need for new water resources stating the water demand would increase significantly as the population is expected to grow by more than two million in the next twenty-five years.

A spokesperson for Mr. Butcher says the region has one of the most reliable water supplies in the country and water supply bodies say their is a comprehensive plan in place to ensure the region’s water supply.
