Agbar Water Bills

Hi, we recently had an astronomical water usage of 230 M3 in 20 days, which is about 11000 litres a day and we weren't even in the house. A very minor leak was found but.... This plus the current water situation led us to focus on water consumption quite a lot.

Our latest Agbar bill showed 14 M3 when we were only there for 2 weeks religiously trying to obey all current advice. We thought that pretty good until we compared with our UK usage which is around 80 M3 for 6 months which includes garden watering/baths/ someone who thinks 20 mins is OK for a shower, the usual extravagance.

Agbar claim their meter is sound, and there is no visible evidence of huge amounts of water leaking within the house or garden. Has anyone had issues with Agbar meters?

Unfortunately, we are in Calonge which is on Agbar's to-do list for Smart water meters 

So first question is: Is a M3 standard across UK and Spain?? - joke

Seriously, does anyone have an english translation of the various elements on an Agbar water bill? Specifically what is the Canon Aigua ACA, which seems to make up a large % of the bill   

Many thanks
