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.

Mandatory Water Conservation Measures Remain in Effect

Since the mandatory Stage 1 water restrictions were implemented for the Lake Major supply area on September 10, Halifax Water has seen a 9% decline in overall consumption.

Halifax Water is encouraged by the public’s response and respectfully asks everyone to do their part to conserve water where they can. As these dry conditions persist and with little rain in the forecast, all residents and businesses supplied by the Lake Major Water Supply Plant must follow mandatory Stage 1 water conservation measures until further notice.

This impacts water service for the communities of Dartmouth, Burnside, Cole Harbour, Westphal, North Preston and Eastern Passage
