Sewer surcharges shall be based upon the average of the analysis of at least two samples taken during any one month and shall remain in effect for a minimum of one month. Sewer surcharges will be billed with the regular sewer service bill. A surcharge may be assessed for BOD or COD, but not for both parameters simultaneously. No reduction in sewer service charges, fees or taxes shall be permitted because of the fact that certain wastewaters discharged to the sanitary sewer contain less than the maximum allowable concentration as defined above.

Establishments involved in the preparation of food for commercial or public purposes shall provide grease interceptors or traps. The interceptors or traps shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperatures and shall be of substantial construction, gastight, watertight and equipped with easily removable covers. For new or remodeled (food handling) establishments, the minimum capacity for an exterior-type grease trap five hundred (500) gallons, based upon rectangular dimensions that will support a liquid (depths) of at least three (3) feet and six (6) inches. Existing food handling establishments must within two (2) years of written notification, install grease trap(s) on all wastewater drain piping, except floor drains. For existing facilities, approved floor or flush mounted, under the fixture units will be permitted. The capacity of such units will be determined by the size, number and types of fixtures utilized by the grease trap.
