It is unlawful for any person to tamper with or make any connection to the sewer system, without written permission, or to reconnect any water or sewer service when it has been disconnected for nonpayment of a bill for service, until such bill has been paid in full, together with any reconnection fee which might be charged. It shall likewise be a violation of this chapter for the owner or occupant of any residence or other building required to be connected to the public sewer to fail to cause such building to be connected. (Prior code § 4-1-5)
