Collect water - use for pouring
This saves wastewater fee. At the same time you have water ready for pouring in the dry season. I do it this way: Shower always comes first, always cold water from the tap. I let this water run into a bucket and then dump it into my rain barrel, which is standing outside. Also the "residual water" from the kettle is there. In the kitchen I place in my sink a plastic bowl, because if I Wash vegetables and the peeled potatoes, you need a lot of water. One does not even believe how many liters of water "pointlessly" run into the drain! And if you take it for watering, at least it serves a good purpose.
