I’ve wanted to do a short series on data centers because there is a lot of information, misinformation, and fear surrounding them.
My purpose is not to argue for or against data centers. It is to take the major concerns one at a time, separate what we know from what we assume, and talk honestly about the real risks, benefits, and unanswered questions.
Yesterday LV Fact Checker asked me about water use, so let’s start there.
Do data centers use a lot of water?
Some absolutely do.
Google opened its Council Bluffs, Iowa data center in 2007. In 2025, Alphabet reported that the site consumed about 1.35 billion gallons of water.
That is a big number and a legitimate concern.
But Council Bluffs uses evaporative cooling, which consumes water as part of the cooling process. Other designs, including closed-loop liquid cooling and dry cooling, can use considerably less.
You cannot take the water use from one facility and assume every data center will operate the same way.
One concern I hear locally is that a large data center could drain the water table or leave residents, farmers, and businesses without enough water.
I specifically asked about that in my discussions with KDHE.
There are different state agencies involved. KDHE deals with public water systems and related engineering. Water rights and water appropriation are handled through the Kansas Department of Agriculture’s Division of Water Resources.
The takeaway was simple: a large industrial user cannot just show up and take unlimited water. The source, available supply, existing users, and ability to sustain the demand all have to be considered.
That does not mean I am comfortable taking anyone’s word for it.
I want to know the actual annual and peak water demand, where the water is coming from, whether the source can support it long term, what cooling system is being used, whether there is any evaporative component, and what happens during drought conditions.
Those answers should come from engineering and water-supply data, not talking points.
I have also heard the claim that closed-loop systems have to be completely drained and refilled every year. I have not found evidence that this is a universal industry requirement. Maintenance varies by system and can include testing, topping off, or condition-based replacement rather than a complete annual drain.
So where do I land?
I think the concern is real, but I also think some of the discussion has gotten ahead of the facts.
If a project is going to use hundreds of millions or billions of gallons of water a year, I want that known before anyone makes a decision.
But I am also not willing to assume that every data center proposed in Kansas will use water the same way as Council Bluffs.
Show me the cooling design. Show me the water demand. Show me the source. Show me that it can be sustained without creating an unacceptable impact on the people already living, farming, and doing business here.
If the numbers hold up, we should recognize that. If they do not, we should recognize that too.
My goal with this series is simple: take the claims one at a time, verify what we can, acknowledge what we do not know, and have the discussion based on evidence instead of fear or salesmanship.
If you have a source that challenges something I have written, send it to me. I will read it.
