HOW TO MISLEAD WITH STATISTICS 1010:
26 million litres is 26,000 tonnes. Divide by 365 and you get 71 tonnes/day/MW, or 3 tonnes/hour.
1MW converted to heat with 31% efficiency will boil 3 tonnes in almost exactly an hour.
So our 1MW data centre is converting about 69% of its energy into computation.
The real efficiency problem is not the water consumption (although we need better heat sinks than potable fresh water!) it's the MIPS/MW ratio.
