Should it become necessary to shut off water from any section of the system because of any accident or for the purpose of making repairs or extensions, the Department will endeavor to give timely notice to the consumers affected thereby and will, so far as practical, use reasonable efforts to prevent inconvenience and damage arising from any such causes; but the failure to give this notice shall not render the Department or the city responsible or liable in damages for any inconvenience, injury, or loss which may result therefrom.
