Living in the upper third of Georgia we have been on no hose usage outside for anything for the past two years due to our severe drought. Some year we will out of this drought but I do not see the powers that be letting us use a hose to wash a car again - ever!
The government here had to pass a special piece of legislation so people and communities could fill/refill their pools. Water cops are all over the place.
ONR is the way to go for saving water and is an environmentally friendly product. Win - Win for me.
