The purpose of this article is to control discharges of fats, oils and grease (FOG) in the wastewater flow from food preparation establishments and other commercial facilities into the Publicly Owned Treatment Works (POTW) collection system. FOG interferes with the normal operation of the collection system by causing buildup that decreases line sizes and restricts flows, blockages and plugging of pipelines and contributes waste of a strength or form that may interfere with the operation of the treatment facility. All new and existing facilities that generate and discharge fats, oils and grease in their wastewater flow shall install, operate and maintain a FOG pretreatment system. The requirements of this article shall be supplement and in addition to the requirements of the City of Parkersburg’s Sanitary Sewer Use Ordinance and Pretreatment Ordinance. (Ord. 1395. Passed 6-14-11.)
