New Zealand's wastewater infrastructure is in crisis, and the consequences are spilling into the environment. The recent sewage disaster in Wellington is a stark reminder of the looming threat.
According to water engineer Iain Rabbits, the industry is facing a critical shortage of skilled operators, and this is just the tip of the iceberg. With 35 years of experience, Rabbits reveals that the root cause of wastewater failures, such as the recent Wellington incident and the 2016 Havelock North spill, lies in systemic issues.
But here's where it gets controversial: the problem isn't just about hiring more people; it's about the industry's failure to invest in training and support. Rabbits argues that the lack of experienced workers is a direct result of inadequate training and a lack of mentorship. He compares the water industry to the electrical sector, where apprentices receive years of supervised training, while in water, operators are often left to fend for themselves with little guidance.
The situation is further exacerbated by the highly technical nature of modern treatment plants. These facilities require meticulous monitoring and maintenance of complex instrumentation and automation systems. And this is the part most people miss: operators need to understand these systems to respond effectively when issues arise.
Rabbits believes that the Moa Point plant failure is a wake-up call, highlighting the need for comprehensive training and support for operators. He suggests that the industry's issues are long-standing and well-known, yet they persist due to a lack of investment and transparency at the governance level.
Interestingly, there is no legal requirement for plant operators to hold any qualifications. While a water operator assessment is available, Rabbits emphasizes the importance of on-the-job learning alongside experienced colleagues. This lack of mandatory qualifications raises questions about the industry's commitment to safety and sustainability.
Wellington Water's CEO, Pat Dougherty, acknowledges under-investment at the Moa Point plant, suggesting that early warning signs may have been missed. The resignation of Wellington Water chairman Nick Leggett further underscores the gravity of the situation, as he takes responsibility and aims to restore public trust.
An independent government review has been announced to investigate the Moa Point failure, but the real question remains: Will the industry finally address the root causes, or will history repeat itself?
