Sipriano v. Great Spring Waters of America, Inc., 1 S.W.3d 75 (Tex. 1999)

Why this matters: A bottling company pumped 90,000 gallons a day and drained the neighbors’ wells. Texas held that they had no legal claim at all, and that fixing it was the legislature’s job. The perfect contrast case. Wisconsin abandoned this rule in 1974. Texas kept it.

Doctrine: Groundwater, rule of captureabsolute dominionPump as much as you want from under your own land, even if it drains your neighbor's well, with no liability. Nearly every state abandoned this. Texas largely kept it.

Case name and citation

Sipriano v. Great Spring Waters of America, Inc., 1 S.W.3d 75 (Tex. 1999).

Court and year

Supreme Court of Texas. Decided 1999. Opinion by Justice Enoch.

One-line holding

Texas retains the common law rule of captureabsolute dominionPump as much as you want from under your own land, even if it drains your neighbor's well, with no liability. Nearly every state abandoned this. Texas largely kept it. for groundwater, and any change to it should come from the legislature rather than the courts.

Facts

In 1996, Great Spring Waters of America, operating as Ozarka, began pumping groundwater in Henderson County for bottling. The rate was about 90,000 gallons per day.

Sipriano and other nearby landowners watched their wells go dry.

They sued for nuisance and negligence and asked for an injunction and damages.

The trial court granted summary judgment against them. The court of appeals affirmed. Both relied on the rule of capture, which Texas had followed since Houston & Texas Central Railway Co. v. East in 1904.

The rule of capture says a landowner may pump as much groundwater as they choose, without liability to neighbors whose wells are depleted, subject to limited exceptions for malice, willful waste, and negligent subsidencesubsidenceThe ground surface permanently sinking after too much groundwater is pumped out. It destroys the aquifer's ability to hold water again, so it cannot be undone..

So the landowners went to the Texas Supreme Court and asked it to replace the rule of capture with a rule of reasonable usereasonable useYou can use the water however you like until it unreasonably harms someone else's use. This is Wisconsin's groundwater rule. The catch: it is enforced by a lawsuit after the harm, not by a permit beforehand..

Should Texas abandon the rule of capture for groundwater in favor of the rule of reasonable usereasonable useYou can use the water however you like until it unreasonably harms someone else's use. This is Wisconsin's groundwater rule. The catch: it is enforced by a lawsuit after the harm, not by a permit beforehand., which would impose liability on landowners who unreasonably use groundwater to a neighbor’s detriment?

Holding and reasoning

The court declined and affirmed.

It did not defend the rule of capture on the merits. The opinion is notably unenthusiastic about it. The court acknowledged that “Sipriano presents compelling reasons for groundwater use to be regulated.”

It also reaffirmed the court’s general willingness to change the common law, quoting its own language about “the genius of the common law” resting “in its ability to change, to recognize when a timeworn rule no longer serves the needs of society.”

The reason it refused was institutional. A 1917 amendment to the Texas Constitution made conservation and regulation of natural resources a duty of the legislature. And the legislature had recently acted: Senate Bill 1, passed in 1997, expanded the authority of local groundwater conservation districts and set up a process for locally driven regulation.

Given that, the court said, “any modification of the common law would have to be guided and constrained by constitutional and statutory considerations,” and it was not appropriate “to insert itself into the regulatory mix” while a legislative scheme was getting started.

The court repeatedly qualified its holding with “at this time.” The change Sipriano sought was “not appropriate at this time.” A concurrence went further, suggesting the rule’s days might be numbered if the legislative approach failed.

That phrasing was a message: the court reserved the option to revisit.

Why it matters

Put this next to State v. Michels Pipeline Construction (1974) and you have the cleanest illustration in this library of how much groundwater doctrine is a policy choice. See 1974-state-v-michels-pipeline.md.

Wisconsin faced the same question and reasoned that modern hydrogeology had destroyed the factual premise of absolute ownership. It overruled its own 1903 precedent and adopted a reasonableness standard.

Texas faced the same question, agreed the rule was hard to defend, and kept it anyway on separation of powers grounds.

Same science. Same era. Opposite answers. That is why “what are my water rights?” has no national answer.

The practical consequence in Texas is a system where the aquiferaquiferUnderground rock or sand with water in the spaces between the grains. It is not an underground lake. Water seeps through it slowly, often only feet per year. is effectively a common pool that anyone with land above it can draw down, unless a local groundwater conservation district has been formed and has adopted rules. Coverage is uneven, and district authority varies.

The story got more complicated 13 years later. In Edwards AquiferaquiferUnderground rock or sand with water in the spaces between the grains. It is not an underground lake. Water seeps through it slowly, often only feet per year. Authority v. Day (2012), the Texas Supreme Court held that groundwater in place is owned property, which means regulating it can be a compensable takingregulatory takingWhen a government rule restricts your property so severely that courts treat it as taking the property, which would require payment. Wisconsin courts have been unusually willing to say a shoreline rule is not one.. See 2012-edwards-aquifer-authority-v-day.md.

The combination is remarkable. Under Sipriano, your neighbor can pump your well dry and owe you nothing. Under Day, if the government limits that pumping to protect you, it may have to pay the pumper. Texas built a system that protects the extractor from both directions.

What it means for a landowner today

The rule of capture does not apply in Wisconsin, and hasn’t since 1974. Do not carry Texas intuitions north.

What transfers is the diagnostic question. When evaluating land anywhere, ask: if a large user next door starts pumping hard, do I have a remedy?

  • In Wisconsin, potentially yes under Michels if the harm is unreasonable, plus a permitting layer where a high capacity wellhigh capacity wellIn Wisconsin, a well (or all wells on 1 property combined) capable of pumping 100,000 gallons a day or more. These need DNR approval. An ordinary house well does not. requires DNR approval and the DNR has a duty to consider impacts on waters of the state.
  • In Texas outside a groundwater conservation district, generally no.

Wisconsin’s protection is meaningful, and it is not automatic. It depends on the DNR actually evaluating impacts, which is exactly what Lake Beulah and Clean Wisconsin fought over. See 2011-lake-beulah-v-dnr.md and 2021-clean-wisconsin-v-dnr.md.

Subsequent history / is it still good law

Good law as of July 2026. The rule of capture remains the Texas common law baseline for groundwater.

Two significant developments since. Groundwater conservation districts have expanded substantially under the framework the court deferred to, and they now regulate pumping across much of the state, with real variation in stringency.

And Edwards Aquifer Authority v. Day (2012) recognized a constitutionally protected ownership interest in groundwater in place, which constrains how aggressively those districts can regulate without paying compensation. Bragg v. Edwards Aquifer Authority, decided by a Texas court of appeals in 2013, awarded compensation on those grounds.

So the modern Texas position is: capture at common law, local district regulation by statute, and a takings backstop protecting the owner’s interest against that regulation.
