What the stormwater system design needs to address

The design of the stormwater system needs to address:

the Auckland Council standards, including the requirements of the regional Network Discharge Consent (NDC)
environmental requirements
minimisation of flood risk to life and property
safety
service life, maintenance risks and costs.

This guideline document sets the standards for designing and constructing:

public stormwater assets
assets to be vested Full transfer of ownership rights and authority over an asset. to the council.

The code of practice is available on the Auckland Design Manual website.

If you are planning a development, we may be able to authorise the discharge of stormwater under our regionwide NDC.

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