Part 4 – Stormwater Drainage
4.11 Location of Pipelines
- Stormwater pipelines within the Residential Zone shall normally be located within the road reserve.
- Stormwater pipelines in the Industrial Zone shall either be located in the road reserve or in the front yard area.
- Stormwater reticulation pipelines (and connections) in the Business Zone shall be either in the rear service lane or in the rear yard of properties where no service lane exists. Major reticulation and trunk lines shall be in the road reserve (as for residential zones).
Where stormwater pipelines are in the road reserve, they shall conform to the standard location of underground services and shall generally be 1.5 m out from the kerb. Where the offset from the kerb varies due to curves in the street, the manholes shall be generally 1.5 m out from the kerb.
Where a stormwater pipeline changes location within a street, it shall do so at an angle of 45 degrees or greater. Where a stormwater pipeline crosses other utility services, it shall do so at an angle of 45 degrees or greater.
On the limited occasions where a stormwater pipeline is within a private property, it is preferable to be parallel to and as near to the boundary as possible so as not to reduce the building area available but also to provide future Council maintenance access to it. No part of the manhole construction shall cross a private property boundary such that a fence or other structure cannot be built over it.
On sloping ground, the stormwater pipeline should be within the property of the higher land (to avoid conflict with excavation levelling of the lower property).
An easement is required for all pipelines within private property.
Where the pipeline gradients are greater than 1 in 5, it is expected that anchor and/or anti-scour blocks shall be constructed.
No new private drains shall pass between one property and another. If crossing of private property is unavoidable, those parts of the pipeline serving more than one lot shall be Council mains with service connections to the property boundaries.
Where Council pipes pass through private property the requirements of the stormwater bylaw in regard to building over or adjacent to a stormwater pipeline shall apply – see section 4.2 of this Part.
Pipe location for works under all consents should facilitate future subdivision.
