Any water or wastes containing dissolved or suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant. 9. Any noxious or malodorous gas or substance capable of creating a public nuisance. 10. Any pollutant releases, (including demanding pollutants i.e. B.O.D., etc.) in a discharge of such volume or strength as to cause interference in the sewage works. Section 15-2-13 Preliminary Treatment; Required Approval Whenever objectionable and prohibited substances exist in the characteristics of a user's wastewater, the owner shall provide at his expense, such preliminary treatment as may be necessary to, 1.
