There's skyrocketing water charges on the way for Wellingtonians in coming years. 

An average Wellington household's water bill tops $2500 a year.  

Indicative council figures suggest by 2033, that'll climb to $7,000 in a new billing system with water separate from other rates. 

Councillor Tim Brown says it covers stormwater, sewerage, and drinking water.

"It has approximately doubled in about the last five years - so it was closer to where Auckland's were five years ago. And it's quite hard to actually fully understand why our network is in such bad condition."
