Fresh water: Some nice stuff you can do here. Our Well water in the area is pretty good.
Now fluoride is more toxic than lead and would cost big business a fortune to dispose of so it gets dumped into most of the drinking water in the U.S.A. More than 60% of the States in the U.S.A. practice this. Research bottled water – you may want to revisit what you are drinking there too. (Thought I would throw that in for you ?).
Photo shows shower on left with drain. There’s a washbasin on the ground in position with the toilet on the right. Toilet has hot water too, bidet. Note the 3″ sewer cleanout in the backgrond, angled up to allow for the berm. The trench in front of the bathroom will be an internal wall. Perhaps doubling up as support for the huge window in the loft?
So in our dome home, water comes into the building from the water well and is branched to the kitchen and washer with separate lines Tee’d off to the bathroom. We will use an instant water heater for electrically heating water for “on demand” hot water. (Winter use?) This is cheaper than running a hot water cylinder and also saves space.
A separate hot water supply system heated by a black water piping system wrapped around the outside of the dome as well as finned copper piping wrapped around the wood stove stack, will be our other source of hot water. This will also be used to supply water to a tub. (outside the building – earthbag construction, insulated).
The bathroom is compact. The shower will have two seperate hot water suipplies: Electrically heated water on the left hand side with the alternative hot water faucet on the right hand side. Both systems feeding into a common shower rose. More on this later.
Pressure test the whole system before laying your floor over it. Can’t afford to have a leaking pipe can we?
You can obviously catch rain water and build tanks from earthbags too.
