A historic moment of New Zealand’s first “earthquake proven” Seismic Resilient Ductile Iron Pipe installed.

The bulk water, bridge mounted water transmission pipeline has been commissioned at the isolated Kaitoke Bridge construction site. Construction site operators were trained by Kurimoto of Japan. The bridge pipe-section was completed ahead of time and now conveys raw water to the Te Mārua Water Treatment Plant.

SRDIP has survived some of the world’s largest earthquakes including: Great East Coast Japan (2011) Tsunami – a 9.0mw event and Awaji (Kobe 1995) Earthquake – a 7.3mw event. The pipe-joint, is easily made by pipe fitters with special tools and basic mechanical know-how, it can provide extension and contraction + 60mm and provides greater angular deflection when compared to other pipe joints during a disaster such as Earthquake, Tsunami or Landslide.
