CS-10.1 Fire Hydrants

PreviousNext

Hydrants shall be constructed in the position and with the details shown on the approved drawings.

CS-10.1.1 Hydrant Installation

  1. Drain holes for frost protection are not permitted. If the hydrant is drilled for this purpose, the hole shall be plugged.
  2. Hydrant tees shall be flanged if laid next to other flanged fittings. Otherwise flexible joints are permitted (gibault or supertite).
  3. Hydrant risers shall be used, or the water main laid deeper, where necessary, in order to ensure the top of the spindle is between 100mm and 250mm below the finished surface level.

CS-10.1.2 Hydrant Boxes

The following shall apply to the construction of hydrant boxes:

  1. Hydrant boxes shall be constructed as per the approved drawings with the cast iron valve box set flush with the finished ground surface.
  2. Hydrant boxes and risers shall be fitted with lifting cleats to assist installation.
  3. Surface boxes set in sealed surfaces (carriageway or actual footpaths) shall be surrounded by such edging and with the immediately adjacent concrete set within a square boxed-out construction joint if required.
  4. The lid and concrete surround shall be painted yellow in accordance with NZ PAS 4509 specification.
  5. A yellow fire hydrant triangle roadmarking shall be painted with its base next to the road centerline in accordance with NZ PAS 4509 specification.
  6. A blue cat’s eye double sided reflective marker shall be adhered to the centreline of the carriageway opposite the hydrant in accordance with NZ PAS 4509 specification. 
  7. In kerbed residential streets the kerb shall be painted yellow on both the face and top of the kerb, in line with the painted yellow triangle and the hydrant itself and for a length of 500mm. A marker post is not required.
  8. In un-kerbed streets and rural areas, concrete marker posts of approved type shall be set vertically in the ground within 300mm of the lot boundary and immediately opposite the hydrant which it indicates. Hydrant indicator posts shall be painted yellow in accordance with NZ PAS 4509 specification.
  9. Where a hydrant is in the carriageway, a painted yellow circle around the hydrant shall be provided in accordance with NZ PAS 4509 specification.

In any street with special paving (e.g. cobblestones) the painted yellow circle is not required, however, all other marking requirements described above still apply.
