How we manage stormwater

​Why we manage stormwater

We manage the quantity and quality of stormwater runoff to:

• minimise flooding
• maintain the environmental value of our aquatic habitats
• prevent the pollution of our seas.

Stormwater infrastructure

Stormwater infrastructure consists of assets including:

• 6000km of pipes
• 45,000 manholes
• 6700 catchment pits
• more than 900 treatment devices.

These are used to manage rainfall runoff from urban areas.

Stormwater bylaw

The stormwater bylaw helps protect our waterways by ensuring stormwater systems are of a consistently high standard across Auckland.

For more information, see the Stormwater Bylaw.

Auckland region Network Discharge Consent (NDC)

The NDC sets out a range of requirements for connecting to the stormwater network and assets to be vested to the council.
