The dairy effluent WOF programme consists of a voluntary, independent inspection of a farmer's effluent infrastructure and practices.

After extensive testing with over 200 farmers, Effluent WOF is now available to farmers and rural professionals around the country.

The Effluent WOF programme is insightful and practical, covering the entire

effluent system.

An independent assessor points out areas of risk and suggest practical actions a farmer can take to ensure their system is capable of being compliant 365 days a year.

A 3-4 hour assessment by the accredited assessor covers the farm’s effluent consents and permitted rules, the storage capacity, nutrient loadings, soil risk, irrigator performance, off-pasture infrastructure and general health and safety requirements.

All WOF Assessors are trained professionals who are fully certified as Warrant of Fitness Assessors. Every assessor has completed the Farm Dairy Effluent System Warrant of Fitness Course and a subsequent field assessment.
