I've never had a hosepipe ban here, despite being in the Southern Water area, because we're lucky enough to have our water supply from underground aquas in the hills of the South Downs National Park, but much of the company's area is water stressed, as is the Portsmouth Water area, hence this joint project, which will reduce the need of over extraction from rivers during periods when they are running at low levels, and help to protect wildlife and the wider environment.
But, I am not surprised that
