Germany.

Fail: more than a certain number of legionella colonies found in water samples
held at temp X for time Y, in a lab that does such testing.

The samples are taken from taps, with any faucet insets removed, and the mouth
of the tap heated with a flame to sterilize, water running until the temperature
stops rising, temperature measured and noted. Then a water sample is bottled.

So not a "domestic water system", at least as most folk would
identify with in the UK.

But not a "large commercial or industrial premises", either.

Testing is mandated for any hot water system serving three units or more, with
the hot water piping containing more that X liters (1?) of water. While this may
be a racket, ISTR they do find more contamination than they originally expected.
As the symptoms of legionellosis apparently aren't that clear-cut, it may be a
problem that is more widespread than originally assumed.

legionella/Legionellosis is a particularly nasty form of pneumonia; it
doesn't respond to regular antibiotics. It can take some time to diagnose
and it's always possible that the body's own immune system has won.
I had the disease about 30 years ago.
