Definition
A water company is a private or quasi-public enterprise organized to supply water to a municipality, its residents, or other consumers, typically operating under a franchise, charter, or express legislative grant of authority. The term encompasses both privately owned corporations engaged in the water supply business and the contractual and regulatory arrangements through which they operate alongside or in place of municipal government.
Water companies occupy a hybrid position in American law: they function as private enterprises but exercise a public utility function, often holding monopoly or near-monopoly rights within a service territory. This public character subjects them to regulatory oversight and limits their freedom to contract, set rates, or terminate service as ordinary businesses might.
A key structural feature of the water company's legal status is the relationship between municipal authority and private enterprise. A municipality has no inherent or implied power to supply water to its citizens for compensation — that power must be expressly conferred by the legislature. When such authority exists and a municipality contracts with a water company to perform that function, the municipality is generally understood to have committed its public utility authority to that arrangement for the duration of the contract, subject to the terms agreed upon.

Common Language
Modern common usage (Wiktionary): A company that supplies water to customers, typically through a managed distribution network.
Historical common usage (Webster's 1913): Not separately defined; the term would have been understood as a commercial company engaged in the waterworks business.
The gap between common and legal meaning here is structural rather than semantic. In ordinary usage, a water company is simply a business that sells water. In law, a water company is an entity whose authority to operate derives from public franchise or legislative grant, whose rates and service obligations may be regulated, and whose contracts with municipalities carry constitutional and public law dimensions — particularly regarding the impairment of contracts and the limits of municipal power.

Why It Matters in Research
Researchers working in late 19th and early 20th century sources will encounter water companies frequently in the context of municipal corporation law, public utility regulation, and the contracts clause of the U.S. Constitution. The central research trap is treating water company disputes as ordinary contract or corporate law matters when they turn on the scope of legislative delegation to municipalities and the doctrine of ultra vires.
Bouvier's entry captures a doctrine with real consequence: because a municipality cannot supply water for pay without express statutory authority, any contract between a city and a water company that exceeds that authority may be void or unenforceable. Researchers tracing the history of a particular franchise arrangement must first establish what legislative authority the municipality actually held at the time of contracting.
The exhaustion-of-power principle noted in Bouvier — that a municipality entering into a water supply contract with an existing company has thereby committed its authority — matters in regulatory history research. This concept shaped how courts analyzed whether municipalities could subsequently contract with competing suppliers, build their own waterworks, or renegotiate terms. It is closely related to, but distinct from, the constitutional impairment of contracts doctrine.
Water company cases also appear prominently in the development of eminent domain and rate regulation doctrine. When a municipality sought to condemn a private water company's infrastructure or when companies challenged rate caps as confiscatory, courts were forced to define the boundaries of the public utility framework. These cases sit at the intersection of corporate law, constitutional law, and administrative regulation, and researchers should not limit their searches to a single doctrinal category.
Jurisdictional variation is significant: some states developed robust public utility commission oversight of water companies by the early 20th century; others left rate and franchise matters to municipal ordinance or contract well into the mid-20th century. The corpus will reflect these differences across state reporters.

Historical Dictionary Support
Bouvier's entry, though fragmentary in the available text, encodes two doctrines that were well-settled by the late 19th century and are worth flagging for researchers.
First, the no-implied-power rule: municipalities derive their authority from the state legislature, and the power to engage in a commercial water supply business is not incidental to general municipal incorporation. This restates the orthodox Dillon's Rule understanding of municipal power, applied to a specific and economically significant context.
Second, the exhaustion principle: once a municipality has contracted with a water company under valid legislative authority, it cannot simply grant the same authority again to a competitor or itself without addressing the existing arrangement. The Bouvier text breaks off before completing this analysis, but the implication is that the municipality's power is committed or encumbered for the duration of the contractual arrangement.
What historical dictionaries do not adequately address is the regulatory transformation that occurred after Bouvier's principal editions. The rise of state public utility commissions, beginning notably around the 1907 New York and Wisconsin utility reforms, fundamentally changed the legal landscape for water companies. Bouvier's framing is almost entirely contractual and ultra vires; it does not anticipate the administrative regulation model. Researchers using Bouvier as a guide to early 20th century water company law must supplement it with state public utility statutes and commission decisions from that period.

Jurisdictional Note
The scope of municipal authority to contract with or compete against private water companies varies substantially by state, depending on state constitutional provisions regarding home rule, statutory frameworks for public utilities, and whether the state adopted comprehensive utility commission oversight. Researchers should not assume that the ultra vires limits described in Bouvier applied uniformly in home rule jurisdictions, where municipal power over local services was often broader.
