BTW, not long after I enquired, a Thames Water van appeared and sat in our
road most of one evening with no apparent activity. My suspicious mind
did
wonder whether they were watching for unusual water flow. Not that they'd
have found any since my garden is "green" and if the plants can't survive
on
the rain they get, then they don't!


i understand helicopter surveys are used to spot green gardens in a droght
with no licence.....
