How bloody irresponsible an answer.

It doesnt sound like 'fun' to me. I take very seriously any threat to
Public Water Supplies. Your local Water Inspector might have something
to say about the possibility of a criminal offence, which it could be.

Try reading what was written *carefully* And don't just read what you
obviously want to into it. To me it says the job of making sure the
harvested water on an automatic changeover system doesn't get into the
mains might be 'fun' ie difficult.
