STRAIGHT ANSWER
If data centers are a small share of national water use, does it matter?

Locally, a large campus can be material when it draws potable water in a stressed basin, during summer peaks, alongside other projects. The national share does not settle the local question.

What this answer does not say
- That data centers are a top national water user.
- That a small national share makes a local project irrelevant.
