What about stainless steel? Along the lines of the "In Building Riser" from Ames? Instead of the just the transition/riser portion, use stainless all the way. http://www.nickelinstitute.org/index.cfm/ci_id/14414.htm

We will pipe horizontally underground from that room to a point near one of the glue-lam arches that support the stage canopy (with slope back to the room). Drainage is no longer a problem. We're looking into the wrapping of galvanized pipe. I know some out there would recommend cathodic protection as well. Mark A. Sornsin, PE Fire Protection Engineer Ulteig Engineers, Inc.

I have a cut sheet for it if anyone is interested. Let me know and I will email it out to you. As far as drainage, Eric already mentioned it, a big ugly pit.

This might work in this situation. The drainage is still a problem. -- No virus found in this outgoing message. Checked by AVG Free Edition.
