A group of water experts, students and former councillors is urging the City of Ottawa to ban bottled water in all its arenas and facilities. The Ottawa Water Study Action Group(OWSAG)gathered at City Hall on Monday to both celebrate the quality of local drinking water and ask the city to get out of the plastic water bottle business. "Ottawa tap water is terrific, it is much better than bottle water," said former city councillor Diane Holmes at the meeting.
