Water wastage

Interesting news.

"About 15% of Dunedin's water supply, recently upgraded at a cost of $64 million, is slipping through the cracks.
The figures meant about 2.4 million cu m of water was being lost to leaks and burst pipes each year, council staff confirmed."

and even more interesting

"Dunedin's leakage compared favourably with Wellington, which lost about 20% of its water each year, but poorly with Hamilton, which lost about 11%, Christchurch, which lost 12%, and Auckland, which lost about 14% (or 7.6 million cu m of water) each year."

I've never thought about the leakage of water from old pipes. It seems like a lot of lost water.
