Halifax Regional Water Commission
From Wikipedia, the free encyclopedia
The Halifax Regional Water Commission (HRWC) is a Canadian water utility in Nova Scotia's Halifax Regional Municipality that supplies potable water and fire protection water to the urban core, as well as several isolated smaller systems in the rural areas of the municipality.
[edit] History
The HRWC was formed on April 1, 1996 combining the water utilies of the city of Dartmouth, the city of Halifax and Municipality of the County of Halifax.
Before amalgamation, the Dartmouth water utility supplied the city of Dartmouth as well as the adjacent county communities of Eastern Passage, Westphal, and Cole Harbour from the Lemont Lake watershed east of the city. The Halifax water utility supplied the city of Halifax and the town of Bedford from the Pockwock Lake watershed west of the city.
The Municipality of the County of Halifax water utility supplied the communities of Lower Sackville, Waverley and Middle Musquodoboit.
