The Regional Estuaries Initiative (REI) worked with Western Dairy and south-west dairy farmers to reduce dairy effluent entering our waterways by assisting farmers to upgrade their effluent management systems.
Effluent can deliver large amounts of nutrients into creeks and streams. However, when managed well, effluent can be a valuable source of fertiliser for pasture growth.
Upgrades were co-funded by the farmer and REI and are designed based on Dairy Australia’s industry standards.
From 2016–20, REI completed 21 upgrades throughout the Peel-Harvey, Leschenault, Hardy, Wilson and Oyster Harbour catchments representing 17% of all dairy farms in Western Australia.
It is estimated that the upgrades will capture 146.4 tonnes of nitrogen and 24.5 tonnes of phosphorus each year.
