And it certainly is not the case that greywater would be used as a potable -- or breathable -- source of water or humidity. To obtain greywater in the quantities useful for data center cooling, it typically has to come from the local public water company, and generally requires a local ordinance allowing its use. Moreover, such ordinances will specify exactly what the water can be used for, and plumbing codes will ensure that the greywater will be kept separate from the potable water, much as are waste and storm water.
