There are cup waterers available that are similar to the nipples but are affixed to a water source horizontally. These could be attached directly to a 5 gallon
bucket or what we did was attach them to a pvc pipe, attached to a hose attached to a 5gallon bucket. We put the 5 gallon bucket on a cinderblock and the pvc pipe with the cups on the ground. I don't have a picture of our set up but I've attached a picture of one of the cups. We made this waterer specifically for chicks with their mother hens as the typical chick waterers would get drained by all the adults halfway through the day. The bucket lasts a couple days, although it would probably be longer but there is a tiny leak in it.
Ours are free ranged so bedding getting in the cups isn't an issue for us but if it is for you, you could easily zip tie the pvc pipe to something to raise it up a bit.
