The county board may require convicted persons confined in its jail to reimburse the county for the expenses incurred by their incarceration to the extent of their ability to pay for such expenses. The warden of the jail shall establish by regulation criteria for a reasonable deduction from money credited to any account of an inmate to defray the costs to the county for an inmate's medical care. The State's Attorney of the county in which such jail is located may, if requested by the County Board, institute civil actions in the circuit court of the county in which the jail is located to recover from such convicted confined persons the expenses incurred by their confinement. The funds recovered shall be paid into the county treasury.
