Design of the stormwater system

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.

Stormwater Code of Practice

This guideline document sets the standards for designing and constructing:

• public stormwater assets
• assets to be vested to the council.

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

Auckland region Network Discharge Consent (NDC)

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.

Before applying for the NDC, refer to the Stormwater Management Devices Guide (GD01)[PDF 14MB] and Water Sensitive Design Guide (GD04)[PDF 37MB].
