Karl,
This is on Veolia site which I think you said you come under,
"The level of recharge achieved so far has not been sufficient to restore groundwater resources to normal levels, but has been sufficient to allow for a limited relaxation of the exceptions for businesses (please see below) affected by the drought, so we can help safeguard livelihoods.
UPDATE 13 JUNE
Any person whose business was in existence before 15 March 2012 and whose income is solely dependent on cleaning private motor-vehicles; walls or windows at domestic premises; paths or patios; or other artificial outdoor surfaces may now use a hosepipe for these purposes until further notice. These businesses were previously given a 3 month exception to consider how they might reduce their reliance on mains water until 4 July 2012, this deadline has been removed."
So nothing there about recycling water?
