The purpose of Practice Note 27 (PN 27) is to offer industry guidance in the design and construction of some key infrastructure components that are related to farm dairy effluent management on New Zealand dairy farms.
It is a good-practice reference source for engineering practitioners, contractors, agriculturists, product suppliers, regional council and local authority staff and others involved in the dairy industry. Farmers will also find this a valuable technical resource. It is divided into five separate parts (see download links below) covering; legislation, solids separation, underpasses, concrete structures and feedpads.
