A Southern Queensland local council has called for more funding to upgrade water infrastructure as Roma residents are asked to cut out non-essential water use due to a depleted supply.

The town's water reserves are diminished due to high, heat-related consumption and multiple equipment breakdowns, according to Maranoa Regional Council.

Council utilities spokesman David Schefe says while $10 million per year was spent on upgrading water infrastructure, the "exasperated" council needed more state and federal funding.
