Why it matters

Some supportBrind's analysis of the reports

The failure was attributed to a combination of interacting technical and organizational factors. These factors included apparent design flaws, such as critical electrical equipment being located below ground, and the absence of sensors for high water levels. The incident resulted in the emergency, unconsented discharge of untreated wastewater.

Tiaki Wai provides essential water and infrastructure services within the defined geographical boundaries of Wellington. The company is regulated by the Wellington City Council.
