Stormwater is the water that runs off surfaces such as roads, driveways, footpaths and rooftops. It travels down gutters, into sumps and enters the stormwater network.

Facts about the Wellington stormwater network:

  • 650km of pipes
  • 20km of tunnels
  • 51 years average age of pipes
  • $639 million value
  • 79 million cubic litres per year

Keeping it Clean

Stormwater is discharged - untreated - into Wellington harbours and streams. That's why it's important to keep it as clean as possible. The Council commits resources each year to improving water quality in the inner harbour and along the south coast.

We have thorough sampling schedules and standards to test stormwater for pollution from sewerage, heavy metals and other contaminants.

Residents and businesses must also do their part to keep the stormwater network healthy. Under the Resource Management Act, it's illegal to allow anything other than rain to enter the stormwater system.

To report a pollution incident, please call the Greater Wellington Regional Council Pollution Hotline: 0800 496 734.

Reporting Problems

Every year the Council responds to about 12,000 calls to fix leaks and other problems with water, sewer and stormwater systems. If you come across a problem, please report it to the Council with specific details of the leak's location.
