Inuvik Water Treatment Plant (Interior)

Water Treatment Plant - Inuvik, NT

The Town of Inuvik owned and operated two water supply and associated treatment facilities to provide potable water for the community on a year-round basis. The pre-existing water treatment plants were reaching intended lifespans and needed to be upgraded or replaced. A new water treatment plant opened in March 2017. This new plant allows Inuvik to have a single source of water year round as opposed to relying on water from Hidden Lake in the summer and the Mackenzie River in the winter. Dillon designed a new water treatment solution that draws water from a single source instead of the two water supplies.

Wastewater Treatment Facility - Amherst, NS

Beginning with its founding in 1764, Amherst, like many Canadian communities, discharged its municipal wastewater untreated to nearby watercourses. For many years, the town’s raw sanitary effluent discharged to a series of outfalls along the Amherst Marsh, with the flow proceeding to the LaPlanche River and ultimately the Bay of Fundy. Efforts to address the town’s wastewater treatment requirements extend back to 1979. Following Dillon’s preparation of the detailed design and tender documents and the selection of Brycon Construction Limited as the general contractor, development of the $11 million facility was initiated in June 2010, with the official opening taking place in October 2012. This project received the Lieutenant Governor’s Award for Excellence in Engineering from Engineers Nova Scotia in 2014
