I have captured the bath shower water by placing a pond pump in the tub when we are finished and have it collect and distribute to the holding tank by a hose exiting the window and flowing into the tank. The tank is a water tank people here use to have at cabin sites to hold water. I collect the kitchen sink (our busiest water source) and change the plumbing in the spring summer to collect as seen in the following picture. This works quite well and provides us with about 200 gallons per day to be pumped out of the holding tank onto our garden. I have a large submersible sump pump that provides good water pressure to the sprinklers we use to disperse it. We don't get much water after July so this is when I use this to minimise my water neads. When raining all of my rain water is diverted from the run off spouts underground in non perforated pipe (4") To the nearest garden bed where it is then allowed to percolate out of 4" perforated drain pipe into the soil of a nearby bed. This is all done with gravity. Each pipe is open on the end with a cap that can be easily removed to flush out debris that may collect in the pipe. All down hill with a drop of over 20' so easily cleaned out.
