Tēnā koe Alex,
Official information request (our ref: 26-049)
Thank you for your official information request.
With respect to points 2 and 3 below, an IT search generated close to
18,000 results. Each result may contain multiple pages. Due to the
extensive and complex nature of reviewing this volume of material, we
would need to refuse your request under section 17(f) of the Local
Government Official Information and Meetings Act 1987, as the information
cannot be made available without substantial collation or research.
2. Internal communications between WW personnel pertaining to the incident
3. Communications between WW and Wellington City Council pertaining to the
incident
Therefore, to enable us to process your request and provide a meaningful
response, we will need you to refine or clarify the scope of these parts
of your request.
Thank you.

With respect to items 2 and 3 of my initial request, please ignore those two items and proceed with the remainder of the items in the request.
In addition, please provide technical details:
1. The location of the pipe/fitting that failed
2. Its age
3. Details of its inspection history
4. The capacity of the pipe at the failure location, including its diameter, working pressure (head) and the maximum theoretical volume of water per second that could leak from that location
5. The location and relevant technical details of any downstream blockage in the sewer system identified on the incident date that could have contributed to wastewater surcharge in the Victoria St / Cuba St / Karo Drive vicinity.
Kindest regards,
Alex B
