(a) The board of commissioners of any sewer district may employ an inspector and fix the inspector's compensation, which shall be a portion of each connection fee collected.
(b) The inspector shall make an inspection after the party making the connection has excavated down to the sewer main but before the sewer main is tapped, and then the inspector shall make a second inspection after the tap or connection is made to the sewer main but before the section of the sewer main, which is tapped, is backfilled with earth, so that the inspector can see that the connection is properly made and well cemented in place.
(c) Where two (2) or more sewer districts embrace an area that is adjacent to or overlapped by the various sewer districts, the boards of the several sewer districts may jointly employ an inspector who shall look after connections on the lines of the different sewer systems by which he is employed, in which case, the permit issued shall show not only the location of the connection to be made, for which the permit was issued, but on the lines of what sewer district the connection is to be made.
