The city of Lewisville is participating in the fourth annual North Texas Holiday Grease Roundup, which runs from Monday, Nov. 27, through Monday, Jan. 8. Lewisville residents can bring their used holiday cooking oil and grease to the Steven L. Bacchus Public Services Center, 1100 N. Kealy Ave., between 8 a.m.-5 p.m. Monday through Thursday, and 8-11 a.m. on Friday. Thanksgiving’s fried turkeys, buttery foods and gravy can be hard on pipes and sewer systems. When fats, oils and grease are washed down the drain they stick to the inside of pipes hardening and building up until they cause clogs and sewer backups. This can cause sewage to overflow into homes, streets and local waterways. Whether the repairs are in your home or in the street it can be costly and inconvenient. The collection not only protects pipes, it also diverts a valuable resource from being wasted in landfills. The used cooking oil and grease collected during this event will be used to create biodiesel, or turned into biogas for energy production. For more information, visit ceasethegreasentx.com.
