In February 2015, Halifax Water undertook a stakeholder consultation in support of an application to implement a Seasonal Disinfection Program. Since 2017, Halifax Water has turned off the Ultraviolet (UV) systems annually between November 1 and April 30 at the Halifax, Dartmouth, Eastern Passage, and Herring Cove Wastewater Treatment Facilities (WWTFs). Prior to 2020, UV systems at all of these facilities were turned back on between December 24 and January 2 to provide disinfection during the Polar Bear swim in the Herring Cove area.
