delivered the opinion of the court:
The plaintiff, Village of Bolingbrook (Village), filed multiple ordinance violations against Citizens Utilities Company of Illinois (Citizens), alleging the illegal discharge of untreated sewage. The trial court dismissed the complaints when it found the Village’s public health ordinances were preempted by the Illinois Public Utilities Act (Utilities Act) (Ill. Rev. Stat. 1989, ch. 1112/3, par. 1 — 101 et seq.). The Village appeals and we affirm.
Citizens is a public utility which provides water and sewer service to the Village. Between April 9 and April 15, 1991, Citizens discharged untreated sewage from its plant onto property located in the Village. The Village, a home rule municipality, filed 22 complaints against Citizens for repeatedly violating ordinance 24 — 200 (“Unlawful Placement of Waste Prohibited”) and 20 complaints for the violation of ordinance 24 — 201 (“Unlawful Discharge into Natural Outlet”).
Citizens moved to dismiss all complaints on the basis that the Utilities Act preempted the Village from enforcing its public health ordinances. The trial court agreed and granted Citizens’ motion to dismiss.
The Village maintains that it is authorized by the General Assembly to prohibit Citizens’ illegal discharge of untreated sewage pursuant to: (1) the Village’s general police powers (Ill. Rev. Stat. 1989, ch. 24, par. 11 — 1—1); (2) the Village’s ability to regulate offensive matter and prevent pollution within the municipality (Ill. Rev. Stat. 1989, ch. 24, par. 11 — 80—10); (3) the Village’s ability to enact ordinances for the promotion of health or the suppression of diseases (Ill. Rev. Stat. 1989, ch. 24, pars. 1 — 2—1, 11 — 20—5); and (4) the Village’s ability to prevent and abate nuisances (Ill. Rev. Stat. 1989, ch. 24, par. 11 — 60— 2)-
The Utilities Act was enacted by the General Assembly and intended to govern the operation of all public utilities within the State of Hlinois. (Ill. Rev. Stat. 1989, ch. 1112/3, par. 1 — 102.) Section 1 — 102 of the Utilities Act provides in pertinent part:
“Findings and Intent. The General Assembly finds that the health, welfare and prosperity of all Illinois citizens require the provision of adequate, efficient, reliable, environmentally safe and least-cost public utility services at prices which accurately reflect the long-term cost of such services and which are equitable to all citizens. It is therefore declared to be the policy of the State that public utilities shall continue to be regulated effectively and comprehensively.” Ill. Rev. Stat. 1989, ch. 1112/3, par. 1 — 102.
The Illinois Commerce Commission was specifically created by the General Assembly and authorized to supervise and regulate all public utilities within the State of Illinois. (Ill. Rev. Stat. 1989, ch. 1112/3, par. 4 — 101.) According to section 4 — 101 of the Utilities Act:
“The Commission shall have general supervision of all public utilities, *** shall inquire into the management of the business thereof and shall keep itself informed as to the manner and method in which the business is conducted. It shall examine those public utilities and keep informed as to their general condition, their franchises, capitalization, rates and other charges, and the manner in which their plants, equipment and other property owned, leased, controlled or operated are managed, conducted and operated, not only with respect to the adequacy, security and accommodation afforded by their service but also with respect to their compliance with this Act and any other law, with the orders of the Commission and with the charter and franchise requirements.” (Emphasis added.) Ill. Rev. Stat. 1989, ch. 1112/3, par. 4 — 101.
The term “public utility” encompasses every corporation or business which owns or operates any (utility) plant which provides sewerage disposal. (Ill. Rev. Stat. 1989, ch. 1112/3, par. 3 — 105.) Citizens is a public utility as defined by the statute because it provides sewage disposal and related services to individuals and businesses located in the Village.
A “home rule unit” is a municipality which “may exercise any power or perform any function pertaining to its governmental affairs including, but not limited to, the power to regulate for the protection of the public health, safety, morals and welfare.” (Ill. Const. 1970, art. VII, §6(a).) Home rule municipalities are granted broad and imprecise powers. This requires the courts of our State to determine whether a power exercised by a home rule municipality is within the scope of the powers granted by article VII, section 6(a), of the Illinois Constitution. Ampersand, Inc. v. Finley (1975), 61 Ill. 2d 537, 338 N.E.2d 15.
The validity of any municipal ordinance depends upon whether the municipality has been granted the appropriate governmental power by article VII, section 6(a), of the Illinois Constitution of 1970. (Kirwan v. Peoples Gas Light & Coke Co. (1988), 173 Ill. App. 3d 699, 528 N.E.2d 201.) If the General Assembly has not specifically limited or denied a governmental power to a home rule unit, then the courts must determine whether the legislature intended to preempt the area of authority which is the subject of the municipal ordinance. Hutchcraft Van Service, Inc. v. City of Urbana Human Relations Comm’n (1982), 104 Ill. App. 3d 817, 433 N.E.2d 329.
Preemption occurs when the courts determine that the General Assembly has adopted a method of regulation covering the same subject matter that a municipality is also attempting to regulate. Hutchcraft Van Service, Inc., 104 Ill. App. 3d at 823, 433 N.E.2d at 333.
The Illinois General Assembly has not specifically prohibited home rule units of local government from regulating public utilities. (Kirwan, 173 Ill. App. 3d 699, 528 N.E.2d 201.) However, the General Assembly has conferred upon the Illinois Commerce Commission the power and authority to comprehensively regulate all public utilities within this State. (Ill. Rev. Stat. 1989, ch. 1112/3, par. 4 — 101.) When the Utilities Act expressly empowers the Illinois Commerce Commission with a specific regulatory authority, any similar regulatory power vested in a municipality becomes ineffective. City of Geneseo v. Illinois Northern Utilities Co. (1941), 378 Ill. 506, 39 N.E.2d 26.
In City of Peoria v. Peoria Water Co. (1977), 49 Ill. App. 3d 1066, 364 N.E.2d 1003, the trial court dismissed the City of Peoria’s complaint for specific performance on the ground that the city’s attempt to regulate water main extensions was preempted by the Utilities Act. The City sought to compel the local utility to provide water main extensions pursuant to their existing franchise. Our court upheld the trial court’s dismissal. We found that neither the City’s municipal ordinances nor the parties’ franchise could limit the Illinois Commerce Commission’s authority to regulate the local utility. Therefore, the court found that the City of Peoria could not compel the local utility to provide water main extensions without receiving specific authority to do so from the Illinois Commerce Commission. By our opinion in the instant appeal, we reaffirm the doctrine of preemption as set forth in City of Peoria.
The alleged discharge of untreated sewage by Citizens is a matter of concern not only to the residents of the Village, but also to the people of the State of Illinois. The regulation and general supervision of all public utilities in this State have been solely and specifically vested in the Illinois Commerce Commission by the Utilities Act (Ill. Rev. Stat. 1989, ch. 1112/3, par. 4 — 101 et seq.). The general regulation of public utilities by the Illinois Commerce Commission has been, since 1913, a matter of statewide, not local, concern. Kirwan, 173 Ill. App. 3d at 705, 528 N.E.2d at 203.
We find from our review of the record that the Utilities Act grants to the Illinois Commerce Commission regulatory control over Citizens’ operation of its sewerage service and preempts such regulation by the Village. However, we note that our holding in no way precludes local Village regulation over public utility matters which do not interfere with or overlap the regulatory authority of the Illinois Commerce Commission. (City of Chicago v. Hastings Express Co. (1938), 369 Ill. 610, 17 N.E.2d 576.) Our opinion does not preclude municipal regulation of the nonintegral public activities and facilities of a local utility. See City of Chicago v. Alton R.R. Co. (1933), 355 Ill. 65, 188 N.E. 831.
For the reasons indicated, the Illinois Commerce Commission has exclusive regulatory jurisdiction granted by the Utilities Act over the operation of Citizens’ public utility sewage system and service. The trial court acted properly when it dismissed the Village’s ordinance violation complaints against Citizens pursuant to the doctrine of preemption.
Accordingly, the circuit court of Will County is affirmed.
Affirmed.
