Re: my previous post about a dry standpipe installation, I believe that the large pipe was all standard-type underground pipe: ductile iron as I recall. The much smaller connection for the drain may have been handled with some specially lined 2" pipe for the drain. There is a company in southern California somewhere (Santa Fe Springs?) which will cement-line steel pipe for you on a custom basis. I have used their services on government-only jobs in the past where function was more important than listing. This job I am referring to was for the county in which the airport is located. Since we needed only about 5' of small pipe, we may have done something else. I don't remember. (Guess I'd make a good politician....)
