Hi!
Does anybody have some experience with read bed purification in dry 
areas? I'v read about it, that it is not practical there, because of the 
high evapotranspiration loss of water. But on the other hand i heard of 
many people that they use it. Do you get water back from that system? 
And can you use the reed propperly?
Are there more effectiv plants to use on that kind of pourification?
