The Systems Repair team at Catchment Solutions offers unique ways to control and mitigate the impact of damaging runoff from intensively farmed agricultural land. The team uses their unique, comprehensive knowledge of wetland systems to devise solutions involving the creation of purpose-built wetland areas specifically designed to capture and ameliorate the damaging sediment, nutrients, herbicides and pesticides carried by runoff that can be responsible for fish kills, dangerous algal blooms and sediment pollution in the Great Barrier Reef catchments.
How it works
When runoff flows directly from farmland into wetlands, the results can be devastating for fish and other animal species, as well as for plant biodiversity. Creating a series of catchment pools to treat runoff before it reaches natural wetland habitats can dramatically improve the health of those wetland systems. It can also create opportunities to capture valuable resources for reuse on-farm that would otherwise be washed away.
Catchment Solutions specialises in creating supplemental wetland areas as capture chambers for sediment and nutrients, including underground irrigation systems for capturing and reusing nutrients, and rock riffles between sections to re-oxygenate water entering wetlands. The result is a complete ecosystem solution, which often extends to include weed control, fishway systems, bank stabilisation, aquatic biodiversity enhancements, repopulation of endemic plant species, and invaluable expert and local community engagement and input.
