Code of Practice

Best practice for managing dairy effluent.

The Code of Practice for Dairy Shed Effluent Western Australia, developed in 2012, outlines the shared industry and agency expectations for dairy effluent management in Western Australia. The Code provides clear standards for effluent management  for all dairy sheds, as well as guidelines for new dairy sheds. The Code is used as a self-regulation tool for dairy farmers and as a reference for referral agencies across the state. 

We benchmarked 32 dairy sheds in 2015/16 against the Code of Practice. Our findings found that the majority of dairy farms required improvements to meet the standards required in the Code. We have supported 10 dairy farms to upgrade their systems from 2017-2020. 

Western Dairy is undertaking a review of the Code, with support from Department of Water and Environmental Regulation. It is expected to be completed in 2021. 

Dairy effluent storage ponds allow effluent to be stored over winter and irrigated onto pastures in summer
