Water questions a Texas landowner should ask first

Groundwater in Texas belongs to the surface owner, which makes water a negotiable part of a land deal here in a way it is not in most states. That cuts both ways, and it is worth understanding before you sign anything.

Most articles about data centers and water are written for people worried about their community’s supply. This one is written for the person who owns the land, because in Texas your position is unusual and it is worth knowing what you actually hold.

Groundwater here belongs to you

Texas treats groundwater as the property of the surface owner, subject to regulation by local groundwater conservation districts. That is different from much of the western United States, where water rights are permitted and allocated separately, and it has a direct consequence for a land transaction.

Water beneath your ground is generally part of what you own and part of what can be conveyed, reserved, leased or negotiated.

That is worth pausing on. In a deal for your land, water is not automatically a throwaway detail. It can be a separately valuable thing, and it can also be something you give away without noticing if the paperwork is not read carefully.

Which is why the paperwork matters here more than most places

If somebody puts an option or a purchase agreement in front of you, there will be language about what is being conveyed. Often that language covers the groundwater along with everything else, by default, without anybody drawing attention to it.

Sometimes that is entirely appropriate and reflected in the price. Sometimes it is not.

This is one of a small number of places in a land transaction where a Texas attorney reading the document earns their fee several times over. Not because anybody is necessarily trying to take advantage, but because the default language conveys more than a landowner often realizes, and once it is signed the conversation is over.

We would say the same about anything we put in front of you. Read it with your own attorney, specifically on this point.

How much water these facilities actually use

Less than the coverage suggests, and it depends almost entirely on the cooling design.

Evaporative cooling uses a great deal of water and is efficient on electricity. Closed-loop and air-cooled designs use very little water and consume more power instead. Some newer facilities are built to use almost no water at all in normal operation.

So the honest answer to how much water a project would need is that it depends on a design decision that may not have been made yet. Anybody who gives you a confident figure very early is either working from a settled design, in which case they can tell you what it is, or guessing.

The question that actually tells you something

Ask what the cooling design is, and what the annual water requirement would be under it.

A party with a real project can answer, or can tell you honestly that the design is not fixed and give you a range. A party who has not got that far will change the subject, and that is your answer about how developed the project really is.

Then ask whether they expect to draw groundwater from the site, buy from a district or municipal supply, or truck it. Those are very different propositions for your land, your neighbours and your own remaining operation.

Why this matters beyond your own deal

Groundwater in much of Texas is a shared and contested resource, and your neighbours know it. In parts of the state the aquifer situation is a live argument at the county level.

If a project on your ground would draw significant groundwater, that becomes a public conversation and you are in it. That is not a reason to walk away. It is a reason to know the answer before somebody at a meeting asks you, rather than after.

What still decides your ground

Water is rarely the first thing that eliminates a Texas property. Transmission is. What runs near you, whether it has capacity, and which wires company or cooperative holds your area remain the questions that settle most sites.

Water is the thing most likely to be underestimated in the paperwork, which is a different kind of risk and worth separate attention.

Where we sit in this

We buy and option land for our own account, with our own capital. Nobody here is paid a percentage of a transaction. Your property is not shopped to a list.

We would rather you took anything we send to a Texas attorney before you act on it, and we would rather you asked us the water question directly and got a straight answer than found the clause later. Most Texas ground we look at does not work for this, and when that is the answer you will hear it plainly.

Send us the county, roughly the acreage, and who bills you for power.

Where this information came from

Selling land for a data center in Texas

See if your land qualifies

Tell us about your property. There is no cost and no obligation. If it does not fit, we will tell you plainly.

A rough number is fine. If you are not sure, write not sure.

Does the property have electric service now?
Is there anything like this nearby that you know of?Check any that apply. Guessing is fine.
Are you the one who decides whether to sell?
Where are you in your thinking?

We use this only to evaluate your property and to contact you. We do not sell your information.
