a new and interesting book, written by a dear friend: Mark Nelson

After seven years I worked with him by e-mail, I finally met at the airport in Istanbul in March 2013, where we were both leaving for Iraq. He is a person truly exquisite and very knowledgeable. His past experiences have given him a lot and all of its current activities are admirable and very appreciable.

Here I show his last book on wastewater treatement within the technology that he has developed and registered: the WasteWaterGarden (TM).
Now available on amazon   and other book web site !!!

Thank you Mark to involve me in your projects
