The Nanoose Bay Peninsula Water System was established in 2005 by amalgamating the water service areas locally known as Madrona, Wall Beach, Driftwood, Nanoose (Beachcomber), Fairwinds, Arbutus Park, and West Bay. The water supply comes from a series of groundwater wells located in the Nanoose Bay Peninsula, and is supplemented seasonally (as required) with water from the Englishman River. The water supply is chlorinated and stored in several reservoirs throughout Nanoose Bay. A water treatment plant designed to remove iron, manganese, ammonia and sulphur from the well water was constructed in 2012. By the end of November 2012, Nanoose Bay Peninsula water system customers were receiving a much-improved combination of filtered and unfiltered drinking water.
