The project was initially approved, but then in 2012 the Hastings District Council decided to abandon it. In 2013 the then mayor, Lawrence Yule, said "when I look at the implications of spending millions of dollars on upgrading bores, I am struggling to understand why we have to do this".
With the benefit of hindsight we can now conclude this decision was a terrible mistake. But then again, we all make mistakes. Why hold the former mayor to account 5 years later? The answer of course is that if voters don't hold their elected leaders to account, nobody will, and then there will be no accountability. We can look to history for myriad examples of what happens next.
It's instructive to compare the Hawke's Bay example with what happened recently in London, when the terrible Grenfell Tower fire claimed the lives of at least 80 people. The elected leader of the Kensington and Chelsea Council, and the deputy leader, have now both resigned.
The chief executive has stepped aside from all his other responsibilities to focus on the public inquiry. Both locals and outsiders can see that the relevant elected leaders are being held to account, and that officers seen to have given bad advice are likely to be held accountable also.
In Hawke's Bay we've experienced our own avoidable tragedy, the water poisoning, in which a far higher proportion of the population suffered serious health consequences, and from which many people have yet to recover and some never will.
So far, however, neither the mayor nor the chief executive have been seen to be held accountable.
Is that going to happen or not? And if it doesn't, what message will that send to our other elected leaders, and the officers who work for them?
