Luckily we have water tank at our new house. We had installed 2 at our last house, so we can water the garden without guilt or worry about the water bill. It has been so dry lately and I really enjoy standing out there watering the flowers. Problem is, I only get to do it for about 4 seconds before one of the kids pull the hose of me with cries of "I want a go".
But anyway at least they have fun watering the garden too.
