Here's the best i could do.
this pic shows the vortex coming out of the ground underneath the deck.
the vortex is buried about 4 1/2' in the ground.
The vortex diameter came out to be around 33-34", and almost 5' tall.
Vortex has been running for about a year and a half.
In this next pic you can see the vortex wall a little better. Not very thick, but it is fiberglass. Little bit flimsy, that's why it isn't a perfect circle.
The microscreen has been running for well over a year now.
And with this pic you can see how I have it in perspective to my pond.
I don't have much land, so I had to put everything close together. The vortex is right next to the pond. In order to hide it, I built a second level abstract deck to cover it. I cut a small access door, to service the microscreen.
