Water meter.

I got to thinking about how much water we've used over the years, I checked on some past photos and noted the new water main and meter were installed back in February 2010, I also noted that the gang who installed them was led by a former mayor and were very productive, unlike almost everything else I've witnessed of late.
Anyway we've now used 152 kilolitres, so I suppose about 40 kl per year but I make a bit of an effort not to waste too much. Considering about 200 kl falls on the roof every year a person has to wonder about the compulsory expense of town water.
