New Zealand Wastewater Treatment Plant Inventory


The New Zealand Wastewater Treatment Plant Inventory has been updated based on data collected in the 2015/16 National Performance Review in 2017. It contains location data and details for 252 Waste-water Treatment Plants (WWTPs) across New Zealand. An interactive ArcGIS map can be found on our website on the ‘NZ WWTP Inventory’ page under ‘Policies & Projects’. The informative map can also be viewed through Google Earth through a .kml file found on the webpage. A combined data Excel file with more extensive detail is also available for download. Visit the Wastewater Treatment Plant Inventory webpage to access the downlaods.
