The Tally Fox Water Network (TWN) is a steadily growing international professional network.  I am continually surprised at the high level of expertise, experience and level of education of the member of the network.  There is truly a vast level of expertise among member of the TNW from very different background and from working under different legal frameworks, this make for interesting discussions and one can get new and unique insights on issues and solutions from around the world.   TNW is a very worthwhile network to below to, and the GIS group which I am associated with has had some insightful discussions and assistance to member is always available.
