Apply for a new stormwater connection

What you need to know before you apply for a new stormwater connection

You need to apply for a new stormwater connection and include it in an existing building consent.

A building consent is needed because as-built private plans for the property need to be updated to reflect the changes.

If you don't have an existing building consent application, you will have to apply for one at the same time.

You will also need written permission from the property owner if the pipe runs through another property.

All connections must comply with the Building Act and the Stormwater Code of Practice.

​Different types of engineering approval

Your required engineering approval - major or minor - depends on the size of your project.

We process new stormwater connection approvals within 20 working days.

• We will let you know the decision by email and post.

• Find a registered plumber or drainlayer to do the connection. To find a registered plumber or drainlayer, visit the Plumbers, Gasfitters and Drainlayers Board website.
• When the work is complete, we will inspect it to check that it meets all conditions of the connection consent.

Stormwater connection inspections

When your registered plumber and drainlayer completes the work, you will need to book an inspection to check that all the conditions of the stormwater connection consent have been met.
