Inland wastewater systems will be under huge pressure, if predicted sea level rise continues.

A report from Local Government New Zealand shows predicted damage to council infrastructure nationwide would cost approximately $8 billion.

Water New Zealand technical manager Noel Roberts says it will back the water level up inside the sewers.

He says the infrastructure will be under pressure and it will have to cope with higher volumes.

Andrew Dickens asked his listeners what they thought about this, especially in light of a recent story that the West Coast Regional Council demanded more information on climate change from the Government.

One caller, Jake, says that people don't have the knowledge or time to appreciate the horror of these reports. 

But another, Gavin, questioned where all the water that would raise the sea levels is coming from. 

Pete drew the debate back to the recent talk of a heat wave, claiming the current temperatures are what he felt as a kid.

He says that he owns a property in Fiji and a sea wall near his house has never once been breached.
