leak testing sewer pipe
(OP)
New construction leak testing sewer pipe -> air testing or hydrostatic testing can be done for smaller diameter sewer pipes (<24"), but how would one go about testing or checking larger diameter sewer pipe (24" or larger)? Thanks

I would caution however, that if testing of individual joints is used (an option it appears of at least the latest reference) this scheme does not test the installed condition of pipe barrels etc. Some folks apparently employ various schemes as well of water, as well as vacuum/external pressure testing of pipelines and manholes etc.
Everyone have a great Thanksgiving!

If you specify air testing and something goes wrong, you will not have followed the industry testing standard.
There are many debates in the Piping forum that air testing is sometimes the correct choice in process piping. I am unaware of any reason to use air testing in civil works.

Good point.
I assumed, perhaps incorrectly, that the OP was testing sanitary force main at 100 to 150 psi, in which case air testing should not be used.
The articles you refer to are for testing at perhaps 10 psi, which can be used for gravity sanitary sewers.
