Waikato dairy effluent breaches lead to $108,000 in fines
Two farmers and two farming companies were recently convicted and fined a total of $108,000 for environmental offending.
Farm trials are underway to ensure the technology works effectively across various farming environments.
Developed by Ballance Agri-Nutrients, Plucks Engineering and Southwater, the technology aims to address a significant environmental and regulatory challenge in New Zealand’s dairy sector. In addition, the by-product of the system is a nutrient and water source that can be recycled on farm.
“Incorrect disposal of effluent can land farmers with fines in the hundreds of thousands, and regulations restrict effluent application during rainy conditions, meaning farmers are often left with an issue to deal with,” says Stuart Kay, innovation lead at Ballance.
“This technology is designed to be a reliable, sustainable solution, transforming waste into a resource that improves compliance and lowers risk. By providing control over water and nutrients, we’re offering a pathway for more responsible and effective farm management.”
The new effluent management system, first conceptualised in 2020, offers dairy farmers an easy way to retrofit a practical solution to meet both current and future effluent storage and regulatory demands. As regulations evolve, farmers often need to renew their consents and invest in upgrading effluent systems to ensure adequate storage, control, and mapping.
Additionally, current regulations cap nitrogen application from effluent at 150 N/ha/year, meaning farmers must carefully manage their land area to avoid over application per hectare. The effluent system has been developed to aid farmers to specifically meet these requirements.
Plucks Engineering has been at the coal face of dairy effluent for nearly 30 years and says it knows and understands the burden dairy farm effluent can impose.
We love what we have developed together with our partners which removes all the stress for the farmer and gives them complete control of their effluent from day one, while removing all the risk and liability,” says Neil Pluck, managing director at Plucks Engineering.
Southwater’s core business is the dredging of municipal and industrial pond slurries into high-capacity dewatering systems to separate the water from solids. The project with Ballance and Plucks is a natural extension of the approach but with critical steps in the process being dairy specific.
