Consumers shall prevent unnecessary waste of water and keep all water outlets closed when not in actual use. All water outlets, including those used in conjunction with hydrants, urinals, water closets, bathtubs and other fixtures, must not be left running for any purpose other than the use for which they were intended. In addition to the penalty provided herein for code violations, the water supply may be turned off where any such waste occurs. (1976 Code § 14-8-8)
