Throw out the bath water, great for the garden.

  We love our 50 gallon bath tub, but sad it uses so much water.  We don't use it that often but sometimes my elementary school age son wakes up at 6AM and pulls himself a hot bath.  Our irregular bath habit was sending A LOT of water to the sewer, while our lemon tree was looking thirsty in the garden.
I stopped in at The Urban farmer to see what siphons and pumps they might recommend for a gray water set up. I walked out of there with a SiphonAid, male/make hose adaptor, a 25' hose, and some great design ideas from the staff.  First we tried to run the hose out the bathroom window and off the balcony on the SAME floor as the bathroom.... but the water output was a disappointing trickle.  
I needed something more dramatic.  
So I set up a siphon hose to run the water out the window and down a story to the garden resulting in a an impressive flow of water.   (Please remember this set up is not to code as it is not advised to have gray water available where kids could touch or drink. Proper set ups have the gray water drain into covered mulch basins. )  A cool feature is that we can hang the hose outside the window when not in use.
