During the period of nonconnection or disconnection, habitation of such premises by human beings shall constitute a public nuisance, whereupon the Board shall cause proceedings to be brought for the abatement of the occupancy of the premises by the human beings. In such event, and as a condition of connection or reconnection, there shall be paid to the District reasonable attorney’s fees and costs of suit arising in the action. (Ord. 4 §5.5, 1973)
