Outside water supply advice please!

[gazandlucy]

I have just dug an 18" trench 50 metres for armoured cable electrics to my new gargae and am thinking i may as well put a cold water supply in too.

Could some one please advice me on what kind of pipe to bury and if there are any regs i need to adhere too

thanks

Must mean the depth it is buried? Can't be the diameter!
