The New Pond

Good evening!
Have you ever noticed how therapeutic it is to sit beside a crick?
Have you ever thought about all the water running down the drain from your washer or shower?
Our pond is a grey-water pond/ crick. Right now it is fed by our washing machine drain and we will add the tub drain soon. Ass the washer hits the spin cycle water rushes out the pipe in the foundation into the upper pond.
As each pond refills, it overflows into the pond below and, eventually, through my garden.
This seriously cuts down on watering and I've never seen vegetables grow the way grey water makes them grow!
What is your grey water conservation technique?
