To minimise the potential for impacts on aquatic ecosystems, sewerage networks need to be well maintained and capable of handling and treating influxes of domestic, industrial and commercial wastewater. To prepare for forecast continued population growth, Rockhampton Regional Council is implementing a plan of action that is set to improve sewage treatment in Rockhampton and thereby improve the quality of treated wastewater entering the Fitzroy River.
Grain growers in central Queensland produce more than a quarter of Queensland’s grain harvest. Farming practices can also contribute to water quality pollution that is impacting on the Great Barrier Reef. The Grains Best Management Practice (BMP) program is a voluntary program developed to help growers assess their management practices against industry standards and develop action plans to improve.
The extreme rainfall of the 2010-2011 year flooded 45 of the 57 coal mines in the Bowen Basin, resulting in the loss of more than $2 Billion in coal export earnings. The release of salty water from flooded coal mines can pose environmental risks to downstream river systems. This case study reports stewardship actions taken by Anglo American’s Metallurgical Coal Business Unit to better manage risks associated with water management at their open cut coal mines.
In the 2011 floods, the Fitzroy Barrage fish ladder was virtually destroyed by large rocks and flood debris. A modified design was developed by Fitzroy River Water, incorporating a stainless steel cover and stronger internal baffle plates. The $95,000 project was completed in late 2012. The structure came through the recent 2013 floods (which peaked at 8.6m in Rockhampton) with no apparent damage. The new fish ladder is expected to withstand future flood events and continue to provide a functional passage for migrating fish, with little ongoing maintenance.
