Rehabilitation of the Whitefish Bay Water Distribution System

This project entails the replacement of aged and undersized watermain in Lac Seul First Nation to meet current water demands and fire protection, in accordance with current regulations and standards. The existing 50mm watermain is significantly undersized and is insufficient and poses a significant health and safety risk to the community.

Specifically, the infrastructure upgrades to be completed include: 

• Replacement of the aged and undersized 50mm watermain, with the properly sized 150mm watermain.

• Replacement of the aged an undersized and waterline (lake crossing).

• Reconnection of existing water services to existing homes and buildings; and

• Supply and installation of two (2) upgraded high lift pumps.

The work will require excavation and removal of the existing small diameter watermain within the community and for the lake crossing (in water works). In water works will include utilizing a floating barge for settling the watermain on the lake floor and the use of siltation currents around the barge and watermain route area.  All in water works will be completed outside of the fisheries concern windows to be determined in consultation with MNR and DFO, but generally from approximately June 15th to September 15th or during the winter season through the ice.

The project requires vegetation clearing - the construction work is planned to occur during summer months and will consider the migration, nesting, spawning etc,  timelines of local species, including species at risk. Notably at the time of completing this form, no known species at risk are known in the project location, or adjacent to the project location.

All work is being completed within Lac Seul First Nation Lands, and is the replacement of existing watermain infrastructure (i.e. no new expansion into undeveloped areas).
