   (a)   The village jail shall be used for the incarceration of all persons arrested for violating any laws of the state, the United States or for violating any provision of this code or other village ordinance until such person shall be brought before a magistrate for a hearing or until such person shall be lawfully transferred to some other place of incarceration.
   (b)   Any person convicted of a violation of any provision of this code or other village ordinance and sentenced to the payment of a fine may be imprisoned for the nonpayment of such fine. Such persons may be imprisoned in either the village jail, or in the house of correction of the City of Chicago or such other place of incarceration with which the board of trustees has made the necessary arrangements for such transfer of prisoners. When so incarcerated, prisoners shall be allowed to work out their fine at the rate provided by statute.
