We need a layout based on Water Pollution Issues

From my research, water reclamation isn't really an issue. It's a process.  I'm not really sure what we could do with water reclamation.  It's just the process of recycling waste water (sewage, or toxic water).

I drew this little dummy diagram up, I want to get this set in stone before we move to far forward.  Take a look at this Designers and think about the issues.  how we could layout the map and what the goal is along each path (this image is nothing official, it's made to inspire).
