OPINION
Opinion by
We are asked to decide whether governmental immunity applies to and bars this suit against Bexar Metropolitan Water District for specific performance of a contract to sell real estate. We hold that it does and therefore reverse the trial court’s order denying Bexar Met’s plea to the jurisdiction and render judgment dismissing the cause for want of jurisdiction.
Factual and PROCEDURAL Background
The facts are neither disputed nor complicated. Bexar Met entered into a contract to sell a parcel of land to the Corporation for Education and Economic Development (CEED), acting on behalf of the Education and Economic Development Joint Venture, a Texas not-for-profit joint venture composed of the CEED and the Regional Economic Development Corporation (collectively, “the Joint Venture”). When Bexar Met refused to close, the Joint Venture sued Bexar Met for specific performance of the contract. The trial court denied Bexar Met’s plea to the jurisdiction. Bexar Met then filed this interlocutory appeal. See Tex. Crv. Prac. & Rem.Code Ann. § 51.014(a)(8) (Vernon Supp.2006).
Applicable Law and Standard of Review
Although a governmental entity waives its immunity from liability when it enters into a contract, it does not waive immunity from suit.
Tooke v. City of Memo,
Applicability of GoveRnmental Immunity
The Joint Venture first argues governmental immunity does not apply to this suit because “Bexar Met acted in a proprietary capacity when it purchased and sold the real property at issue for a profit”; and “governmental entities are not entitled to governmental immunity for their proprietary actions.” However, as a conservation district created pursuant to the provisions of article XVI, section 59 of the Texas Constitution,

Bexar Met is a political subdivision of this State and performs only governmental functions.
Bennett v. Brown County Water Imp. Dist. No. 1,
The Joint Venture also argues that governmental immunity does not apply because “[s]uits seeking ... equitable relief have traditionally been excluded from the constraints of governmental immunity because they do not run the same risk of depleting the governmental entity’s coffers.” In support of its argument, the Joint Venture quotes the following statement in
Fed. Sign v. Tex. S. Univ.,
In short, the relevant distinction is not between suits seeking equitable relief and those seeking money damages, as the Joint Venture argues, but between suits seeking to compel state officers to act within their official capacity and suits seeking to control state action by imposing liability on the State. Here, it is indisputable that the Joint Venture seeks through its suit to require Bexar Met to perform a contract and thus “control state action.” Accordingly, we hold governmental immunity applies.

STATUTORY WAIVER
The Joint Venture next argues that Bex-ar Met’s immunity from suit is waived by section 49.066(a) of the Texas Water Code because this is a suit for breach of a written contract approved by Bexar Met’s board. We of course recognize that Bexar Met is subject to chapter 49. 3 But we disagree that section 49.066(a), as originally enacted in 1995 or as amended in 1999, waives Bexar Met’s immunity from this suit.
As originally enacted in 1995, subsection 49.066(a) provided that “[a] district may sue and be sued in the courts of this state in the name of the district by and through its board. All courts shall take judicial notice of the creation of the district and of its boundaries.” Act of May 25, 1995, 74th Leg., R.S., ch. 715, § 2, 1995 Tex. Gen. Laws 8755, 3760 (amended 1999) (current version at Tex. WateR Code Ann. § 49.066(a) (Vernon 2000)). In 1999, subsection (a) was amended by adding the following sentence: “A suit for contract damages may be brought against a district only on a written contract of the district approved by the district’s board.” Act of May 30, 1999, 76th Leg., R.S., ch. 1354, § 8, 1999 Tex. Gen. Laws 4589, 4591. Although the Joint Venture recognizes that the “sue and be sued” language in section 49.066(a) does not, standing alone, constitute a waiver of immunity,
see Tooke,
1995 Enactment
According to the Joint Venture, we must assume the legislature intended to waive immunity from suit because it enacted section 49.066 after the Texas Supreme Court held that the phrase “may sue and be sued” in an organic statute was “quite plain and gives general consent for [a governmental entity] to be sued in the courts of Texas in the same manner as other defendants.”
See Mo. Pac. R.R. Co. v. Brownsville Navigation Dist.,
The Joint Venture’s argument that the “sue and be sued” language in section 49.066(a) is a general waiver of immunity is foreclosed by the Texas Supreme Court’s decision in
Tooke,
in which the
*30
court reconsidered its holding in
Missouri Pacific
and held that the phrase “sue and be sued,” by itself, in an organic statute, does not waive immunity from suit; “[b]e-cause the phrase means different things in different statutes, it cannot be said to be clear and unambiguous.”
Tooke,
When Bexar Met was created in 1945 “as a governmental agency, a body politic and corporate,” it was given “the powers vested by the Constitution and general laws in such public agency” and other powers, including the general power “to sue and be sued in its corporate name.” Tex. WateR Aux. Laws art. 8280-126 (Vernon 2006) [Act of May 10, 1945, 49th Leg., R.S., ch. 306,1945 Tex. Gen. laws 491, 492-93 (amended 1953, 1957, 1997, 2003)]. The 1945 Act does not indicate that the legislature intended the “sue and be sued” language to be a general waiver of Bexar Met’s governmental immunity from suit. Rather, as with the statutes examined in
Tooke,
it appears the legislature used “common language to refer to [Bexar Met’s]
capacity
to be involved in litigation.”
See Tooke,
In 1995, the Legislature passed comprehensive legislation in an effort to achieve procedural uniformity among the different types of local water districts. See Act of May 25,1995, 74th Leg., R.S., ch. 715,1995 Tex. Gen. Laws 3755; David B. BROOks, Texas PRACTICE: County AND Speoial District Law § 46.3 (2002). As part of this effort, administrative provisions governing many districts created by authority of article XVI, section 59 of the Texas Constitution, which had previously been spread throughout the civil statutes and the Texas Water Code, were brought together in a new chapter 49 of the Water Code. The “sue and be sued” language used by the *31 legislature when it enacted section 49.066(a) in 1995 was substantially similar to that it used in the 1945 Act and the meaning of the words did not change.
Nor do we believe that subsections (b) through (f) of section 49.066 either evidence a legislative intent to waive immunity from suit or are rendered “pure sur-plusage” by a holding that subsection (a) does not encompass a waiver of immunity. Nothing in subsections (b) through (f) references a water district’s immunity from suit. Rather, subsections (d) and (e) affirmatively prohibit the prosecution of certain types of claims against a district except through a quo warranto proceeding; neither constitutes a “clear and unambiguous” statement that immunity is waived for other types of suits. And subsections (b), (c), and (f) apply in suits to which the district is either not immune {e.g., suits for unconstitutional takings) or for which immunity has been waived {e.g., suits under the Texas Tort Claims Act and the Texas Commission on Human Rights Act). We therefore hold that section 49.066 of the Texas Water Code, as originally enacted in 1995, does not waive Bexar Met’s immunity from suit.
1999 Amendment
The Joint Venture next argues that the 1999 amendment to section 49.066(a) waives Bexar Met’s immunity from suits for damages for breach of a written contract approved by the district’s board. 5 We again disagree.
In support of its argument, the Joint Venture cites to the House Bill Analysis, which states that the section of the bill at issue “[ajmends Section 49.066(a), Water Code, to authorize the bringing of a suit for contract damages against a district only on a written contract of the district approved by the district’s board.” Office of House Bill Analysis, Tex. H.B. 846,76th Leg., R.S. (July 28, 1999). However, in construing a statute to determine whether the legislature waived governmental immunity, we may find a waiver
only
if it “is effected by clear and unambiguous language.”
See
Tex. Gov’t Code ANN. § 311.034 (Vernon Supp.2006). The language the legislature actually used in amending section 49.066(a) does not “authorize” a suit against a water district; nor does it expressly waive immunity. Rather, the amendment creates a condition precedent: if a suit for contract damages is otherwise authorized, it may be maintained only if the stated condition is met.
See Travis County v. Pelzel & Assocs.,
It is also quite clear that if the Legislature intended to waive a water district’s immunity from breach of contract suits when it amended section 49.066(a) in 1999, it knew how to do so. See Tex. Loo. Gov’t Code ANN. § 271.152 (Vernon 2005) (providing that “[a] local governmental entity that is authorized by statute or the constitution to enter into a contract and that enters into a contract [for providing goods or services to the local governmental entity] waives sovereign immunity to suit for the purpose of adjudicating a claim for breach of contract ...”); id. § 271.151(3)(C) (expressly applying these sections to water conservation districts). *32 Perhaps even more significant is that it would not have been necessary to include water districts in sections 271.151 and 271.152 of the Local Code Government if their immunity from suit on a written contract were waived by section 49.066 of the Water Code. The more logical conclusion is that, although section 271.152 of the Texas Local Government Code waives a water conservation district’s immunity from suit for breach of a written contract for goods and services, the 1999 amendment to section 49.066(a) requires that these suits be founded upon written contracts approved by the district’s board of directors. A water conservation district thus remains immune from a suit for breach of a contract for the sale of real estate. We so conclude and hold that section 49.066 of the Texas Water Code does not waive Bexar Met’s immunity from the Joint Venture’s suit.
Waiver by Conduct
The Joint Venture next argues Bexar Met waived its immunity from suit and “submitted itself to the jurisdiction of the court” by praying for judgment and costs in its answer, filing a plea in abatement claiming a defect in parties, and obtaining a continuance and an order abating the case to pursue mediation. In support of its argument, the Joint Venture cites
Reata Constr. Corp. v. City of Dallas,
Equity
Finally, the Joint Venture argues that we should apply principles of equitable estoppel to prevent Bexar Met from asserting its immunity because “[j]ustice, honesty, and fair dealing require Bexar Met to fulfill the promise it made to the Joint Venture.” However, the cases the Joint Venture cites in support of its argument require not only that the application of equitable estoppel not “interfere! ] with the exercise of [the entity’s] governmental functions” but also that the “entity has accepted and retained the benefits arising from the contract.”
See City of Hutchins v. Prasifka,
*33 Conclusion
Because Bexar Metropolitan Water District is entitled to immunity from this suit, the trial court erred in denying Bexar Met’s plea to the jurisdiction. We therefore reverse the trial court’s order and render judgment dismissing the Joint Venture’s suit for want of jurisdiction.
