OPINION
¶1 TDB Tucson Group, L.L.C. (“TDB”) appeals from the trial court’s grant of summary judgment in favor of the City of Tucson. On appeal, TDB contends the court erred in ruling that, as a matter of law, the City had no obligation to provide water service to TDB’s real property (the “Property”) *122 located outside the City’s corporate boundaries. For the reasons stated below, we affirm.
Factual and Procedural Background
¶ 2 “In reviewing a grant of summary judgment, we view the evidence and reasonable inferences ‘in the light most favorable to the party opposing the motion.’ ”
Cannon v. Hirsch Law Office, P.C.,
¶ 3 In May 2010, TDB sued the City, seeking declaratory relief and alleging the City had violated its “legal obligation to provide adequate service impartially and without discrimination to all members of the general public to whom its scope of operation extends.” TDB also filed an “Application for an Order to Show Cause why a writ of mandamus should not issue ordering ... the City ... to provide water services to the Property.”
¶ 4 The parties stipulated that the application could be treated as a motion for summary judgment, and the City filed a cross-motion for summary judgment. Relying on A.R.S. § 45-492(A) of the Groundwater Management Act (the “GMA”), TDB asserted that “the residents and landowners in a municipality’s service area are entitled to water service where such service has been established.” And it argued, based upon its interpretation of the definition of “service area” in A.R.S. § 45-402(31)(a), “[tjhere can be no dispute that the Property is in the City’s service area.” The City responded that the Property is not located within the City’s service area as defined under the statute because the City has never provided water service to the Property and that the Property does not contain an operating distribution system owned by the City. The City argued that, although it may choose to serve lands outside its water service area, it had no legal duty to do so in this instance.
¶ 5 After hearing argument, the trial court granted the City’s cross-motion and denied TDB’s motion for summary judgment. The court based its ruling primarily on its interpretation of the definition of “service area” found in § 45-402(31)(a), which reads in pertinent part:
“Service area” means ... [w]ith respect to a city or town, the area of land actually being served water, for a non-irrigation use, by the city or town plus ... [additions to such area which contain an operating distribution system owned by the city or town primarily for the delivery of water for a non-irrigation use.
Because there was no dispute that the Property did not contain an operating distribution system, the court instead focused on the phrase “area of land actually being served water.” It adopted the City’s reasoning and concluded the City had no legal duty to provide water service to the Property. This appeal followed.
Standard of Review
¶ 6 “A trial court properly grants summary judgment if there are no genuine issues of material fact and the moving party is entitled to judgment as a matter of law.”
Airfreight Express Ltd. v. Evergreen Air Ctr., Inc.,
Discussion
¶ 7 TDB maintains the City has a legal duty to provide water service to the Property because it is located within the City’s service area. The trial court, relying on the definition of “service area” found in § 45-402(31), accurately framed the issue at the center of the parties’ dispute as follows:
Here, because the parties do not dispute that the City has never served [the Property] specifically, nor the fact that the property contains no City-owned water infrastructure within its discrete boundaries, the focus is really on how to properly interpret “the area of land actually being served water” found in the statutory definition of “service area.” 2
¶8 On appeal, TDB essentially contends that the trial court too narrowly interpreted the statutory language and that under the court’s interpretation, “no unserved property can ever be considered as included within a city’s ‘service area,’ because it is unserved. Put differently, the City would never have a duty to serve water to any property which is not already served.” TDB argues the phrase “area of land actually being served water” refers to the geographic area generally— rather than a piece of property specifically— and that because “the City provides water service to the properties surrounding and adjacent to the Property,” it is therefore within an area of land actually being served.
¶ 9 “Our principal goal when interpreting a statute is to give effect to the legislature’s intent.”
Blevins v. Gov’t Emp. Ins. Co.,
¶ 10 Based upon its broad interpretation of the statutory language, TDB argues a municipality acting in its capacity as a water utility must provide service to “all who reasonably require service within its area of actual operation.” To support its argument, TDB relies on
Veach v. City of Phx.,
*124
¶ 11 In
Veach,
the owner of a store located in the City of Phoenix sued the city after the store was destroyed in a fire because the city had refused to provide water for fire protection despite the owner’s earlier request that the city install a fire hydrant.
¶ 12 In
Sabin,
the Town of Wickenburg operated water and electric utilities within the town limits.
¶ 13 And in
Travaini,
the City of Phoenix refused to issue a permit to Maricopa County to connect county hospital facilities being constructed within city boundaries to an existing city sewer line.
¶ 14 The issue in each of those cases was the scope of a municipality’s obligation to provide utility service within the city or town boundaries. They stand for the proposition that, although it is not required to do so, once a municipality decides to provide a utility service to its residents, it must do so for all without discrimination. The cases did not address, much less decide, the scope of a municipality’s duty to provide water utility service outside municipal boundaries. Although TDB asserts this fact is neither “dis-positive” nor “relevant” to the outcomes in those cases, we disagree.
¶ 15 TDB also relies on
City of Milwaukee v. Pub. Serv. Comm’n,
¶ 16 TDB’s reliance on City of Milwaukee is unavailing for a number of reasons. First, as the city points out, a portion of the plaintiffs property was located in the City of Milwaukee’s corporate limits and already was being furnished water. Second, to the extent the court held the city had a legal obligation to provide seiwice because it served the “general area,” we reject that proposition. Third, there is nothing in that ease to suggest Wisconsin has the same water conservation policies inherent in Arizona’s GMA that affect a water utility’s ability to provide service. 3
¶ 17 In Arizona, a municipality has the right to provide water service “through its municipal water plant to customers without, as well as within, its corporate limits.”
City of Phx. v. Kasun,
¶ 18 Here, the trial court properly relied on
Cortaro Water Users’ Ass’n v. Steiner,
¶ 19 On appeal, this court affirmed the trial court’s ruling that the well-site property was not in the city’s service area.

¶20 TDB overstates the breadth of the phrase “area of land actually being served water” in § 45-402(31)(a). Notably, the Property is not a single parcel located within a larger area but is comprised of a multi-acre, multi-parcel residential subdivision. Were we confronted with the City’s refusal to provide service to parts of the Property while providing service to others, we might reach a different result.
See Tonto Creek Estates Homeowners Ass’n
v. Ariz. Corp. Comm’n,
¶ 21 Our conclusion is supported by this court’s recent decision in
Yuma Valley Land Co.;
there, the plaintiffs owned real property in an unincorporated area of Yuma County.
Disposition
¶ 22 For the reasons stated above, we affirm the trial court’s summary judgment in favor of the City.
Notes
. The Water Availability letter conditioned the assurance of water availability on TDB’s submission of a water master plan requiring the City’s approval. TDB does not dispute that the letter expired on February 7, 2008, nor does it contend that the City has a contractual obligation to provide water service.
. TDB argues on appeal that the definition of “service area” in the GMA does not apply to this situation. However, in its application for order to show cause filed in the trial court, TDB cited A.R.S. § 45-402(3l)(a), reasoning that under its definition of "service area," "[t]here cfould] be no dispute that the Property [wa]s within the City’s service area.” We acknowledge that in one sentence of a footnote in its ”[r]eply in support of its application for order to show cause,” TDB also stated ”[t]he [GMA] ... does not address water utility services.” And later, during argument on the motions, TDB also asserted that the GMA does not apply to the question whether the City was obligated to provide water to the Property. But, because TDB at various times both relied on the language of the act and rejected its applicability in the trial court, we do not consider this argument further. TDB "may not invite error [in the trial court] and then assign it as error on appeal.”
See Chavez v. Pima Cnty.,
. To the extent TDB suggests the present case can be decided on common law principles, we disagree. "Arizona's common law evolved from the territorial-day view that a landowner has a property interest in groundwater underlying the surface estate.”
Davis v. Agua Sierra Resources, L.L.C.,

was decided, this subsection has been renumbered, but for purposes of this decision, the language is the same.
