Canadian Dam Association Bulletin - Fall 2016 - 11
The infrastructure deficit has been and will continue to be a challenge for the built environment in Canada's cities. A critical public service of cities and municipalities is the supply of
drinking water and process water, and that often means dam infrastructure is part of the asset
mix. Halifax Water, the utility with a mandate to manage water and wastewater for the Halifax
Regional Municipality, has experienced the reality of this infrastructure deficit recently.
Halifax Water owns and operates six dams as part of the water system serving the greater
1. The Pockwock System is the major water supply system for Halifax and is controlled by
2. The Chain Lake System is the backup water supply for Halifax and is controlled by Chain Lake
Dam, with upstream regulation at the Bayer's Lake Diversion.
3. The Lake Major System is the major water supply system for Dartmouth and is controlled by
Lake Major Dam, with upstream regulation at East Lake Dam.
4. The Lake Lamont System is a backup water supply for Dartmouth and is controlled by Lake
Halifax Water follows an established dam management program based on the Canadian Dam
Association's Dam Safety Guidelines. Halifax Water has an active Dam Safety Management System
(DSMS), which it operates within the framework of its Integrated Resource Planning model.
The DSMS includes regular surveillance, operator training and Dam Safety Reviews (DSR) on
a regular basis. The observations and recommendations from surveillance are used in capital
planning for maintenance and replacement.
The Lake Major Dam had been identified for replacement based on activities contained in
the DSR and Halifax Water issued a Request For Proposal (RFP) for replacement design in 2014.
