I used a hose pipe to siphon bath water during a hose pipe ban a few years

me to do this provided they had the right to inspect it. Friend were amused
that I had a visit from one of their officials to see what I did with my
bath water!

How did SW even know about it (or were you just super-honest and
contacted them before doing it)?
