In the event a lot, parcel of land, premises or facility discharging wastewater, industrial process waste, water or other liquids, either directly or indirectly into the city's wastewater collection and treatment system or which eventually enters the system, is supplied with water from any other source other than from the city's municipal water system, then the sewer user charge will be estimated at the average monthly charge for all contributors, unless the owner of the lot, parcel of land, premise or facility installs, and maintains at his own expense, a water meter approved by the city's water department. This meter(s) shall serve as a control for the establishment of the sewer user charge and shall be accessible to the city's meter readers.
