But you're right, regarding to water usage we don't publish numbers (nor does anyone else afaik, I haven't found any WUE number for e.g. Amazon, Yahoo, Facebook...) so it's difficult to compare this to others.
I am however confident that a lot of things have been considered and this was the best option, we have imho a good track record trying to do the best for the environment, a lot of attention is being paid to this internally. E.g. everything running on green electricity, which is not the cheapest.
Look here: https://www.google.com/about/datacenters/efficiency/internal... . PUE globally is 1.06, compared to Yahoo/Cap Gemini Lockports 1.08.

The bandwidth is limited to 10 Mbit/s upstream and downstream.
Still, it's good to have a cheap offsite backup to complement a local one.
80% drives surviving after 5 years seems right, this is what we're seeing as well. The hardware is decommissioned faster then the drives fail.
