9. If the Regulatory and Community Safety Committee determines that the works should
proceed, construction will begin within three months (weather dependent). It is proposed that
the pipe will be installed by horizontal directional drilling, which is a trenchless methodology
designed to minimise disruption caused by construction. The works will take approximately
10 days to complete.
10. It has been explained to all the affected property owners that they have the right to claim
injurious affection (if established) under the Public Works Act 1981.

Context
11. Auckland Council is responsible for managing and maintaining the public wastewater
network in Auckland, much of which is located on private land.
12. Section 181(2) of the Local Government Act 2002 empowers the council to ‘construct works
on or under private land or under a building on private land that it considers necessary for
sewage and wastewater drainage’.
13. Such works require either the prior written consent of the owner of the land, or that the
council follows the process set out in Schedule 12 of the Local Government Act 2002.
14. Schedule 12 requires that affected owners and occupiers are provided with a description of
the proposed works, including plans, and are given the opportunity to object to the works
within one month of notification.
15. If an objection is made, a hearing must be arranged. After hearing objections, the council
must then determine to either abandon the works proposed, or proceed with the works
proposed, with or without any alterations that the council thinks fit.
a) Enabling wastewater management on 331 West Tamaki Road
16. A developer has been granted resource consent by Auckland Council’s regulatory
department to subdivide a property at 331 West Tamaki Road. A condition of that resource
consent is that the new development connects to the public wastewater system.
17. The developer has obtained engineering approval to connect the subdivision to the existing
public wastewater manhole located within 341 West Tamaki Road, see Attachment A. The
connecting pipe will cross under the shared driveways of 339 and 341 West Tamaki Road and
along the fence-line of 341 West Tamaki Road.
18. It is proposed that a 26 metre long / 150 mm diameter wastewater pipe is constructed using
directional drilling, a trenchless method which involves drilling a small hole from 331 West
Tamaki Drive and pushing the pipe underground through to the manhole located on 341
West Tamaki Drive. This method does not involve digging up the shared accessway of 339
and 341 West.
19. Minor excavation works can be undertaken around the outside of the existing manhole. All
excavation and removal of any vegetation or landscaping will be fully re-instated upon
completion of the works.
