When a discharge of waste causes an obstruction, damage, or other impairment to city facilities including, but not limited to, the city sewage system or wastewater treatment plant, the city may assess a charge against the user for the work required to clean, repair and/or replace the facility including overhead costs, and add such charge to the user’s charges and fees. The city shall have such authorities to collect these fees as it has to collect other sewer service charges. (Ord. 2282 NCS §3 (part), 2007.)
