From the 288th Judicial District Court, Bexar County, Texas Trial Court No. 2023CI11920 Honorable Cynthia Marie Chapa, Judge Presiding

Opinion by: H. Todd McCray, Justice

Sitting: Irene Rios, Justice Lori Massey Brissette, Justice H. Todd McCray, Justice

Delivered and Filed: July 8, 2026 AFFIRMED Appellant San Antonio Water System (“SAWS”) challenges the trial court’s decision to grant the plea to the jurisdiction filed by Bexar Medina Atascosa Counties Water Control and

Improvement District Number 1 (“BMA”) and its board members and managers (the “BMA Directors”). We affirm.

BACKGROUND

As this is a memorandum opinion and the parties are familiar with the facts of the case, we will not recite them here except as necessary to advise the parties of this court’s decision and the basic reasons for it. See TEX. R. APP. P. 47.4.

BMA and SAWS are parties to a take or pay water supply agreement (“Agreement”). 1 Under the Agreement, BMA is obligated to provide up to 19,974 acre-feet (approximately 6 billion gallons) of untreated water from Medina Lake to SAWS, “when, and if, water is available in sufficient quantities.” In turn, SAWS is obligated accept delivery from BMA regardless of the water quality, and is obligated to pay BMA for 19,974 acre-feet of water whether it takes it or not. However, if the quantity of water available to BMA is insufficient to meet the demands of the contract, BMA is obligated to grant SAWS a credit for any shortfall.

In its Second Amended Petition SAWS asserts that in recent years, it has chosen to stop receiving water from BMA due to the poor quality of the water—a result of prolonged periods of extremely low water in Medina Lake.

In April 2013, Medina Lake water quality became too poor to be treated at the SAWS ultrafiltration plant which was, in part, due to low lake levels. SAWS therefore elected to stop taking water under the Agreement. Given the unreliable quantity and consistently poor quality of the available water, SAWS could not justify or responsibly commit over $30 million in necessary upgrades to its ultrafiltration plant. The water supply was neither firm, nor dependable, nor of sufficient quality to warrant further capital investment.

1 In 1991, BMA entered into a Water Sale Agreement with Bexar Metropolitan Water District (BexarMet). After entering additional agreements in 1992, 1995, 1999, and 2003, BMA and BexarMet restated and consolidated all their agreements into a single Amended and Restated Water Supply Agreement in 2007. In 2012, BexarMet was dissolved and SAWS assumed BexarMet’s rights and obligations under the Agreement.

SAWS alleges that, since the Agreement requires it to pay for water it is not receiving when BMA does not have sufficient, quality water to comply with the Agreement, these payments amount to a gratuitous grant of public money to BMA that violates article III, section 52(a) of the Texas Constitution (the “Gift Clause”). Based on the assertion that these payments from SAWS to BMA violate the Gift Clause, SAWS has also asserted ultra vires claims against the BMA directors, claiming that accepting those payments and approving budgets funded in part by those payments, are unlawful acts and, therefore, must be ultra vires acts outside the authority of BMA’s directors.

In response to the suit, BMA filed a plea to the jurisdiction asserting the trial court lacked jurisdiction because (1) BMA has governmental immunity; (2) the BMA Directors are immune because SAWS has not properly pled an ultra vires claim; and (3) the PUC has exclusive jurisdiction over SAWS’ claims. The trial court granted the plea to the jurisdiction and dismissed the underlying proceeding. This accelerated appeal followed.

STANDARD OF REVIEW

“We review a trial court’s ruling on a plea to the jurisdiction under a de novo standard.”

County of Bexar v. Steward, 139 S.W.3d 354, 357 (Tex. App.—San Antonio 2004, no pet.) (citing Mayhew v. Town of Sunnyvale, 964 S.W.2d 922, 928 (Tex. 1998)). “In applying a de novo standard of review to a standing determination, reviewing courts construe the pleadings in the plaintiff’s favor, but we also consider relevant evidence offered by the parties.” Farmers Tex. Cnty. Mut. Ins. Co. v. Beasley, 598 S.W.3d 237, 240 (Tex. 2020).

A plea to the jurisdiction typically “challenges whether the plaintiff has alleged facts that affirmatively demonstrate the court’s jurisdiction to hear the case.” Mission Consol. Indep. Sch. Dist. v. Garcia, 372 S.W.3d 629, 635 (Tex. 2012). As the plaintiff, SAWS carries the burden to demonstrate that the trial court has subject-matter jurisdiction over its claims. Dallas Area Rapid

Transit v. Whitley, 104 S.W.3d 540, 542 (Tex. 2003). To determine if they have met that burden, we consider the facts alleged in the petition and, “to the extent it is relevant to the jurisdictional issue, the evidence submitted by the parties.” Id.

“When the pleadings are challenged, we review whether the alleged facts, if true, affirmatively demonstrate jurisdiction; because we construe pleadings liberally in favor of the pleader, we will grant a plea to the jurisdiction without an opportunity to replead only if the pleadings affirmatively negate jurisdiction.” Jones v. Turner, 646 S.W.3d 319, 325 (Tex. 2022). But vague and conclusory statements within a pleading are insufficient to support jurisdiction; otherwise, the jurisdictional inquiry would become meaningless. See Stephen F. Austin State Univ. v. Flynn, 228 S.W.3d 653, 660 (Tex. 2007); Tex. Dep’t of Parks & Wildlife v. Miranda, 133 S.W.3d 217, 226 (Tex. 2004) (holding a plaintiff must allege “facts that affirmatively demonstrate the court’s jurisdiction to hear the cause”); Cnty. of El Paso v. Flores, 677 S.W.3d 31, 43 (Tex. App.— El Paso 2023, pet. denied) (“Generally speaking, self-serving, speculative, and conclusory statements of fact or law are insufficient to raise a material issue of fact; thus, we look to additional evidence in the record to determine whether a fact issue exists.”).

ANALYSIS

Applicable Law on Governmental Immunity Subject matter jurisdiction is essential to a court’s authority to decide a case. Tex. Ass’n of Bus. v. Tex. Air Control Bd., 852 S.W.2d 440, 443 (Tex. 1993). Governmental immunity from suit defeats a trial court’s subject matter jurisdiction and is properly asserted in a plea to the jurisdiction. Miranda, 133 S.W.3d at 225-26; see Jones, 646 S.W.3d at 325 (“At the plea to the jurisdiction stage, governmental officials may challenge jurisdiction based solely on the pleadings or may challenge jurisdictional facts.”).
