Dairy NZ guidance and documentation

DairyNZ provides information on everything from designing and building effluent systems to management, operation and compliance. The goal of this is to maximise the reuse farm dairy effluent (FDE) nutrients on pasture, while minimising adverse impacts on the environment. 

The dairy effluent code of practice was developed with input from Waikato Regional Council. This document is supported as the standard for a dairy effluent system. It guides designers through the process of developing a FDE system, from initial site investigation through to commissioning of the final system. It provides a general design approach, including lists of things that must be taken into consideration.

Institute of Professional Engineers - farm dairy effluent system design and construction

The Institution of Professional Engineers (IPENZ) and Dairy NZ have worked together to develop the folloing good practice guidelines for professional engineers and other technical specialists who are involved in the design and construction of farm dairy effluent systems.

  • Practice Note 21: Farm Dairy Effluent Ponds
  • Practice Note 27: Farm Dairy Infrastructure
  • Practice Note 29: Dairy Housing
