Utilities Kingston has launched a new video campaign reminding residents and restaurants to stop dumping cooking grease down the drain. The YouTube video shows a utility worker wading through murky, knee-deep water to clear a sewage blockage inside a sewage pumping station. "It's toilet waters and solids, anything going down someone's kitchen sink or coming out of someone's washing machine," said Heather Roberts, director of waste and water services for Utilities Kingston, describing the water in the video.
