Utilities Kingston provides over 20 public tours of our water and wastewater facilities each year. The groups range from elementary school grade two students, to graduate students from local and out-of-town universities, and international groups from as far away as China. If you’re interested in arranging a tour for your group, please contact customer service at 613-546-0000.
