70 ILCS 2205/12.1
Actions to impose a fine or imprisonment for violation of a sanitary district ordinance or resolution adopted under authority of this Act shall be brought in the corporate name of the sanitary district as plaintiff. Such actions shall commence with a complaint or a warrant. A warrant may issue upon execution of an affidavit by any person alleging that he has reasonable grounds to believe that the person to be named in the warrant has violated a sanitary district ordinance or resolution. A person arrested upon such a warrant shall be taken without unnecessary delay before the proper officer for trial.
Fines for the violation of sanitary district ordinances or resolutions shall be established by ordinance or resolution and when collected shall be paid into the sanitary district treasury at such times and in a manner prescribed by ordinance or resolution.
A person who is fined for violation of a sanitary district ordinance or resolution may be committed to the county jail or to any place provided by ordinance or resolution for the incarceration of offenders until the fine and costs are paid. No incarceration, however, shall exceed 6 months for any one offense. The committed person shall be allowed, exclusive of his board, a credit of $5 toward the fine and costs for each day of confinement. The sanitary district may make agreements with a county or municipality for holding such persons in a facility operated by them for the incarceration of violators of laws, ordinances or resolutions.
