I have been told by those who experimented with built wetlands in the
Niagara Peninsula of Ontario several years ago that the effluent is close
to drinking water standards. They cannot handle industrial sewage, only
residential.
The gravel used to absorb phsophate has to be renewed every 50-100 years.
It can be used as fertilizer.

Maybe there is more than one type of built wetland? These people used the
term "artificial marsh."
