Infrastructure Development Code

DS-9.4 Design


The following shall apply:

  1. The design of network utilities reticulation and service connections shall be undertaken by a suitably qualified designer for each utility type. The design shall be certified by the relevant network Utility Operator and provided to Council for approval.
  2. The Consent Holder (or Council Project Engineer for Council projects) shall be responsible for:
    1. All arrangements with the appropriate Network Operator for the supply and installation of services for electricity, telecommunications, natural gas (where available), broadband and ducting for future installation of community network cabling (where required by Council).
    2. Ensuring that the network utility service is provided as part of the infrastructure development works.
    3. Ensuring installation procedures conform with the requirements of the IDC.
    4. Obtaining certification from the relevant network utility company that the service has been installed in accordance with their requirements and the IDC
Explanatory Note:
For Subdivisions this shall be before issue of the s224(c) Certificate.
  1. Ensuring all utilities reticulation is constructed using an underground system (overhead cabling shall be considered only in some exceptional rural situations and is subject to Council approval).
  2. Ensuring provision is made for a connection from each utility service to each lot. Providing for acceptable system performance for the whole of the system life which shall be at least 25 years at the time of design.
  3. Cabling for streetlighting shall be arranged with the electrical network provider, in accordance with the requirements of DS-8 Public Lighting and CS-21.6 Public Lighting.


DS-9.4.1 Reticulation Layout


The position of services in the street shall conform to the standard layout as shown in the Standard Drawings. Deviation from the standard location will be allowed only with Council approval. The following shall apply:

  1. All services shall be run parallel to the surveyed street boundary line with a horizontal tolerance of ±100mm.
  2. Wherever the network service crosses a carriageway, whether to cross a side street or for a cross-street connection, the service shall be installed in a duct. The duct shall conform to the requirements of the network Utility Operator. Where the carriageway crossing can be made before the road base is constructed, the duct can be installed by trenching. Otherwise the duct shall be installed by using trenchless methods.

DS-9.4.2 Location of Structures 

The location of above-ground facilities such as transformers, switching stations, gas regulation stations or similar shall be determined in consultation with Council. The following shall apply:

  1. Transformers shall preferably be located in a utility reserve provided as part of the subdivision outside the Road Zone.
  2. The location of these facilities shall be shown on the plans submitted for Infrastructure Development Works Approval.

DS-9.4.3 Utilities on Bridges

The following shall apply:

  1. All installation of services on bridges and the route of approach to the bridge shall be subject to the specific approval of Council.
  2. All services shall be enclosed in ducts that are mounted in positions as determined by Council.

DS-9.4.4 Point of Supply

The point of supply for all network utilities shall be located on the Road Zone boundary of the lot. Provision shall be made for a connection from each network utility service to each lot with the connection being taken to within the lot.

DS-9.4.5 Ducting

The following shall apply:

  1. Ducts shall be laid in straight lines, parallel to or at right-angles to the kerb and/or property boundaries.
  2. The inside surface of the completed duct shall be clean and a draw-wire put in place (when required by the Utility Operator), with end-caps fitted. Installation of ducts with draw-wires and end-caps where the utility reticulation or connection is likely to be installed after roads, footpaths, entranceways and the like are constructed, eliminates the need for trenching through the new surfaces. Alternatively, if cables are to be installed after completion of paved areas and where ducts have not been provided then trenchless installation methodologies will be required.
  3. The duct size, colour and installation shall comply with the network utility provider specifications.
  4. Whenever a service is installed in the duct a replacement draw-wire shall be drawn through and the end caps fitted over the installed service where required by the Utility Operator.
  5. In all business districts where services will be under paved footpaths with high pedestrian counts ducts shall be installed for all network services.

DS- Ducting for Local Authority Broadband Network


The following shall apply:

  1. Where required by Council the design shall allow for supply and installation of a continuous duct-line on both sides of the street. This shall allow for future installation of fibre-optic cables for a broadband network to be developed by the local authorities of the Bay of Plenty.
  2. The ducting shall be 100mmØ uPVC pipe, coloured pink. All ducts shall be fitted with draw wires and end caps.
  3. Ducts shall be located as shown on the Standard Drawings for position and depth.
  4. All ducts shall be installed with tracer wire external to the pipe and shall be strong enough not to break while being pulled with the pipe.
  5. All bends shall be gradual bends. No sharp bends shall be installed in any direction.
