North Shore City Councils stormwater network includes around:

• 863kms of pipes

• 18,000 manholes

• 11,000 catchpits

• 1,800 inlets and outlets

• 80 dams

• 171kms of streams that form a very important part of the stormwater system.

Our wastewater network includes around:

• 1,10km of trunk sewers (300mm in diameter and above)

• 1,100km of local sewers (less than 300mm in diameter). A similar length of private drains connect to the council system.

• 85 pumping stations

• 26,000 manholes.

Out of all these, it is primarily only structures that could have an effect on the environment will need a resource consent. We have programmes in place to assess the likelihood of effects occurring and these will be taken into account by the Auckland Regional Council when considering our resource consent applications.
