Do I need Works Over approval?

Typical projects that require Works Over approval include:

• working close to a manhole

• building over a pipe

• a retaining wall over a pipe

• a vehicle-crossing over a pipe

• trenching of services.

If you plan to work on a reserve, road corridor or other public property, here’s what to do:

1. Check for pipes

To find out if you will be working near our pipes, please register at beforeUdig. This is an online service for anyone planning to work near utility pipes in a public site.

When you have marked your work area on the map, you will receive an email with:

• a utility map showing Watercare’s pipes

• advice on the next steps, including whether you need to apply for approval.

2. Apply for approval

If there is a Watercare pipe near where you plan to work, you will need to apply to Watercare for approval.

 Approval to work near our pipes on private property depends on:

• the size of the pipe

• how close to it you will be working.

Who can advise me?    

If you are working with an architect, builder, engineer or other consultant, they can tell you the location and size of any pipes, and whether you will need approval.

How to check whether you need approval

If you don’t have an advisor, you will need to look at the map showing our pipes and other assets. Follow the steps:
 

1. Check for a pipe and its diameter: 

​Find your site on the GIS map. ​It shows the underground pipes on your site: blue for water, red for wastewater, green for stormwater (this is managed by Auckland Council).

On the map, click on a pipeline to view the type of pipe and diameter:

 

2. Check your clearance distances:
