Effluent management is an important part of any dairy farm business. Good effluent management has a number of benefits both on and off the farm including:
- Saving money on bought-in fertiliser
- Soil conditioning properties from the organic matter
- Improved soil moisture holding capacity
- Improved nutrient holding capacity
- Productivity gains from pasture responses
A series of short video clips explaining key aspects of effluent management is available from the Dairying for Tomorrow website. Each video has an accompanying printable fact sheet summarising the video topic and providing references for further reading or information on the topic.
The Effluent and Manure Management Database for the Australian Dairy Industry website has reliable and scientifically validated technical information on dairy effluent management adaptable to all dairying regions in Australia. This database stores information that underpins state and regional guidelines on dairy effluent management, technical and farmer-based extension programs and educational material.
It includes advice for:
- On-farm effluent designs
- Principles for effective effluent management
- Design criteria for components of effluent containment and reuse systems
- Decision support systems and relevant tools
Agriculture Victoria maintains a directory of accredited private sector providers who provide effluent design services for dairy farmers.
Nutrients from effluent and sludge provide a valuable source of nutrients and organic carbon. Visit the Dairying for Tomorrow website for further information and to access the nutrients from effluent and sludge calculator.
An introduction to the basic requirements of South Australian dairy effluent systems is available in the SA Environment Protection Authority Code of Practice for Milking Shed Effluent.
For a deeper look at the topic:
- Tackling specific effluent issues: Effluent - Dairying for Tomorrow
- South Australian effluent tools and guidelines: South East SA and Adelaide Mt Lofty Ranges Effluent Guidelines
Specific regional effluent guidelines are available for River Murray and Northern and Yorke regions:
- South Australian Murray Basin Effluent Guidelines
- LMRIA Effluent Guidelines
- Northern & Yorke Effluent Guidelines
DairySA is able to seek funding to assist farmers to undertake effluent planning. Natural Resources Adelaide and Mount Lofty Ranges Sustainable Industry grants, Natural Resources SA Murray Darling Basin Sustainable Agriculture program and the Environment Protection Authority (EPA) have all assisted DairySA to allow participating farms to undertake a complete farm effluent system review and have an effluent plan developed by a trained advisor.
Dairy farmers seeking assistance with effluent planning can contact DairySA.
Dairy farmers planning to make more than 200 tonnes of compost in a year require a licence, dedicated pad and runoff pond for the composting area.
Learn more about composting guidelines and requirements from the EPA - Composting guidance.
Wastewater Irrigation Management Plan
The EPA may request a Wastewater Irrigation Management Plan (WIMP) from dairy farmers seeking approval for changes to effluent management on their farm. A Fert$mart Plan and Irrigation and Drainage Management Plan will inform this plan. Fert$mart planners, irrigation system designers and effluent management planners can all contribute to a WIMP.
Learn more about WIMPs.
Australian dairy farmers are among the most efficient dairy producers in the world. To survive in this competitive industry, the production and utilisation of pasture as the main feed source will be the key to the future success of the Australian dairy industry.

Smarter Irrigation for Profit was a partnership between the Australian Government and the major irrigation industries of cotton, dairy, rice and sugar.
