Yes...but we planted them........

Yup......we have a Solar shower otdoor on the patio...that is basically the same....the sun just warms the water up in the vertical tank.....no solar as in electric...just ambient temps. Fill the tank from a hosepipe.
Hubby says it is his favorite ever shower...naked on the patio.......
...has Frightened a few Farmers though......
And the Reeds......do you get the stuff like 30 ft bamboo near you...most people pump it out into a patch of reeds coz they do the same...purify it.....
I've only seen them in France.........if they were here......they have been Eaten........
Friend has tanked water for all his washing etc...system works okay here..they have short fat water tankers coz they are mainly used in out of the way/hard to access places.
We are Lucky...we have mains lecky and water. Plus I'm on the Agricultural water system....so water for the land is Cheap.
