>>548452There are a few more things along the way like plumbing for instance. Things like showers, sinks, washing machines, drains, and toilets.
For water, collect rainwater by having a sloping roof and gutters. collect the rainwater into barrels stored high inside. Use natural filters for water. When the water is held high, you have the benefit of gravity-powered water pressure. From there run pipe to wherever you need. You can even use bamboo if you've been growing it.
You don't have to have a flush toilet! Composting toilets are a good option that avoid plumbing all together and saves water.
Run drain pipe from showers and faucets and washers to plants for grey water irrigation.
If I'm missing anything please let me know I'm still working it out.
