Do I remember it right that during the last hose-pipe ban someone reasonably well known (can't remember who) put a bore-hole in his garden, only for the local water board to show up and demand he stop? They reckoned despite him owning the land, the law gives them the region's water table and so any water under your land! The people that run the water companies are so money hungry that they'd be after Bing's flood if they thought it was worth something
