Water use for cooling data centers is often not directly reported to the state's water use program.

Most are connected to a municipal system (as are many large users these days), with NDAs.

Municipal systems do not report water use within their system to the state (they have their own rights and authorities)

Water withdrawal increases due to data centers can be seen in annual reports of water use.

Power and water efficiencies are sometimes engineered ‘trade secrets’ or part of the marketing of a server/server format.

Re-use of water has high potential. However, WUP is currently unaware of any re-use, though it could be happening.
