Would a data center want my Missouri water, and could they take it?
Missouri does not ration water the way the Plains states do, which is part of why it gets looked at. That is an advantage for a project and it is worth understanding what it does and does not mean for the person who owns the well.

Landowners in Kansas and Oklahoma have to think hard about water because those states allocate it and the allocation is contested. Missouri landowners mostly do not, and many are surprised the question comes up at all.
It comes up because these facilities can use water, and because Missouri’s comparatively relaxed position on it is one of the quiet reasons the state gets looked at.
How does Missouri handle water?
Missouri is a riparian state operating on reasonable use. Landowners along or above a water source have a right to make reasonable use of it, and for groundwater the same reasonableness principle applies.
Permits are not generally required to withdraw groundwater for domestic or livestock purposes across most of the state, and the state does not set a quantity ceiling the way an appropriation state does. What limits you is that your use must not harm your neighbours or the aquifer.
That is a materially different regime from the one a Kansas or Oklahoma landowner lives under, and it is worth knowing you are in it.
Is there any registration at all?
Yes, one, and it is a reporting requirement rather than a permission.
A user with the capacity to withdraw or divert seventy gallons a minute or more from any source, roughly a hundred thousand gallons a day across combined sources, is a major water user and must register once and report use annually.
The important part is what registration is not. It is not a withdrawal permit and it does not license anybody to harm a neighbour. A facility of any size would almost certainly be a major water user, and being registered as one settles a reporting obligation rather than a dispute.
Could a project take my water?
Not in the sense of taking a right away from you. Missouri does not work by allocating shares that somebody else can hold.
What a large neighbouring use can do is affect the resource you both draw on, and that is where reasonable use stops being an abstraction. Reasonableness is adjudicated between neighbours after the fact rather than rationed in advance, which is a genuine difference from the western states and cuts both ways.
For you as the owner of the site, the practical question is not whether somebody takes your water. It is what a project on your ground would draw, from where, and what that means for your own remaining operation and for the people either side of you.
The question worth asking
Ask what the cooling design is and what the annual water requirement would be under it.
The honest answer is often that the design is not settled. Evaporative cooling uses a great deal of water and less electricity. Closed loop and air cooled designs use very little water and more power. Some newer facilities use almost none in normal operation.
A party with a real project can tell you which way they are leaning or give you a range and say why it is a range. A party who cannot has not got that far, and that is your answer about how developed the project actually is.
Then ask where the water would come from: your groundwater, a public supply, or somewhere else. Those are very different propositions for your land and for your neighbours.
Why this is worth raising even though Missouri is easy about it
Because your neighbours are not a legal question and they are still a real one.
Water is the thing rural communities argue about when a project like this arrives, in states where the law is permissive as much as anywhere else. If a facility on your ground would draw significant groundwater, that becomes a public conversation and you are in it. Better to know the answer before somebody asks it across a table at a county meeting.
Where we sit in this
We buy and option land for our own account with our own capital. We take no commission, we do not represent sellers, and your property is not passed to anybody else.
Water is rarely the thing that decides a Missouri property. Power is, and most ground does not clear that bar. But water is the thing most likely to be waved away early and argued about later, so we would rather answer it plainly when you ask.
Tell us the county, roughly the acreage, and the name on your electric bill.
