The so-called Rule of Threes says that we humans can survive three minutes without oxygen, three weeks without food, and three days without water.
So of all the things that our councils provide, is water the most important?
The latest full meeting of Thames-Coromandel District Council received a deputation from Whitianga, whose representative Len Salt told councillors it's been 14 years since a consent was given for water take from the Whangamororo River.
If we have another summer on the Coromandel like we just had, Whitianga would be in a "very dangerous position", he said.
He urged the council to not delay investigating alternative water supply options, as it did at its Annual Plan deliberations in June.
