Due to high inflow and infiltration in some areas, the capacity of the wastewater system has been reached with no extra capacity available to accommodate growth.
We have identified areas in the network with no spare capacity and which require effective management to avoid wastewater overflows. These areas have been grouped into wastewater capacity constraint areas, limited sewer discharge areas, and vacuum sewer areas.
Check your property
Search your property on our interactive wastewater network map to see if you are in an area with wastewater capacity issues.
You can also email wastewatercapacity@ccc.govt.nz if you have further questions.
Wastewater capacity constraint areas
These areas are serviced by gravity wastewater pipes which have reached their capacity and where the risk of wastewater overflows is high.
Limited sewer discharge areas
These industrial zoned areas are on the fringe of the wastewater network and have a daily average sewage flow limit aligned to the property size.
Vacuum sewer areas
Parts of Shirley, Aranui and all of Prestons are serviced by vacuum sewer systems which either have limited or no spare capacity.
