Effluent Management

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

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.

Tasmanian effluent advice, services and contacts

For Tasmanian Effluent Code of Practice and regulatory requirements, contact the Tasmanian Dairy Industry Authority (TDIA) 

For technical assistance with design of effluent systems, contact the accredited effluent designers below. There is no legal requirement to use one of these designers, but they have completed the industry training and have access to the Effluent Design Toolkit software, which is useful for correctly sizing storages, stone traps and other design features.

Farm profitability and sustainability starts with best use of nutrients from fertiliser and effluent. Dairy Australia's Fert$mart project has Tasmanian-specific information and guidelines, including:

  • Soil fertility guidelines
  • Research and trials
  • Local case studies in soil and fertiliser management
  • Regional soils information
