Air Release valve size for infra network.

[ABU]

Hi all,
I have more than 500meter potable water network line connecting to buildings, tanks say 25 branches which installed underground-main line starting from 125mm HDPE SDR11 to 40mm HDPE SDR11. What size of ARV to be used at ground level inside 600X600 ManHole.

I don't know, but I did come across this interesting document a few weeks ago, which may help:
