“Dairy Green” was initially the name of a Sustainable Farming Fund project set up in Southland in 2003. The project aimed to solve the challenge of dairy effluent contaminants entering waterways, particularly after irrigation of dairy effluent with conventional travelling irrigators.
The project was managed by John Scandrett of Scandrett Rural Ltd. It reached a successful conclusion with the development of sludge beds and weeping walls for the filtration of raw effluent and the use of K-line pod sets for low rate irrigation of dairy effluent. When the project was completed, Dairy Green Ltd was setup in 2007 to take this knowledge and expertise to the wider industry.
Since 2003, industry interest and investment in the concept has continued to grow, with hundreds of designs and installations in Southland, as well as in Otago, Canterbury, Marlborough, Westland, and the North Island.
