FYI: We've been given the go-ahead to locate the dry valve in a room below the stage (and below grade). 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.

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.
