Coffs Coast Partnership Leading the Way in Nutrient Management

COFFS COAST PARTNERSHIP LEADING THE WAY IN NUTRIENT MANAGEMENT
North Coast Local Land Services recently completed construction of what may be a world-first triple inline woodchip bioreactor for hothouses. The bioreactor is designed to achieve at least a 95% reduction in nitrate wastewater.
This latest woodchip bioreactor forms part of North Coast Local Land Services on-ground research and development response to mitigating the effects of runoff on local waterways from intensive horticultural farms.
Bioreactors utilise the carbon in woodchips to correct nitrogen-enriched water through a naturally occurring denitrification process where microbes reduce nitrate to more acceptable levels.
The project has been developed in partnership with Coffs Harbour City Council and Southern Cross University with funding from Catchment Action NSW and is one part of the Orara River Rehabilitation Project. Intensive horticulture is expanding rapidly within Bucca Bucca Creek (Upper Orara Catchment) having implications for both the creek’s water quality, and it’s unique assemblage of endangered species.
“The aim of the Bucca Bucca Creek Project is to improve water quality and habitat for endangered species through improved management of nutrients loads, river banks and sediment sources - this latest bioreactor will provide the data needed to develop generic designs for broader adoption by industry”. Shaun Morris from Local Land Services said.
The project has a focus on weed control in the riparian zones and providing education to landholders about best practice land management.
Designed by North Coast Local Land Services and monitored over the next 12 months in partnership with Coffs Harbour City Council and Southern Cross University’s Shane White and Praktan Wadnerkar, this site is fully functional suited to the needs of the farmer as well as an experimental structure.
This is the fourth bioreactor built by North Coast Local Land Services. With ongoing monitoring of previously installed sites in partnership with SCU, NCLLS continues to lead the way in the development of mitigations to managing nutrient runoff in a range of landscape and industry related settings.
