Wastewater Outfalls - International Perspectives Relative to New Zealand

Annual Conference

New Zealand has many wastewater outfalls, the majority of which discharge to the marine environment either at the shoreline, into harbours and estuaries or as offshore ocean outfalls. While the New Zealand approach to outfall siting investigations, environmental effects assessments, resource consenting, and operation and maintenance is well developed, it is timely to carry out a stock take of current international practice.

The author has been closely involved with many of New Zealand’s outfall investigation and consenting projects. As a result of this extensive experience and interest in the topic, he is now a committee member of the International Water Association’s (IWA) Specialist Group for Marine Outfall Systems. He attended the IWA International Symposium on Outfall Systems (ISOS) in Ottawa in May 2016 and from that symposium and input into a global outfalls paper, he has prepared this paper as part of an update and up-skilling for those associated outfalls in New Zealand.
