Grounding dust collection system for static build up?

[Eric Arnsdorff]

The original questions appear to be answered well.
The way I ground my duct work and plastic hose is with aluminum electric fence wire spiral wrapped around the plastic pipe and hose. I use an occasional wrap of electrical tape to hold it in place. I connected it to the water pipe ground wire connection. It is simple, inexpensive and works very well for my setup.
