To make the grind to get more Rivals for the last 15 apparel schematics a bit more satisfying, I tasked myself to count and log all Harvester dumping stations or vaults. Supposedly harvesters go there to dump their harvest.
I found 22 different locations that have 1 or more of these dumping vaults, together they sum up to 88 so far. From high to low:
