Plumbing in natural buildings are usually modern. No one is arguing for a return to the middle ages, and few advocate outhouses (though some do). First principles on plumbing (indoor plumbing) should help here:
- Use less
- Reuse more
Of course immediately awesome and free would be nice. But looking at these principles we can apply a few easy lessons:
- Reuse shower water for toilet flushing, this saves at least as much water as toilet flushing in general, provided showers use is more. Easy peasy.
- Reuse laundry and sink water (e.g., graywater) for outside watering, when/if possible. This includes gardens and agriculture.
- Along with kitchen graywater, compost as much as possible
- Blackwater need not do something trendy such as blackwater earthworm composting (though this can work for kitchen composting), and dry composting toilets are really not necessary, as blackwater
- Note that blackwater goes to a septic tank, then a septic distribution box, and into a leachfield (or something like that)
Use of natural cleaners
It is so very important to use cleaners that both work and do not damage the environment. For example, bleach into the toilet will kill off a lot of the anerobic bacteria and microbes that actually do all the work in breaking down the waste and contaminants. Regular washing maching detergent is usually harmful to microbes and produces algae blooms in local water, and should not be poured directly into the soil, or the sewer.
