The Nanoose Water Service Area was established in 1980 when the Eagle Heights water service area was merged with the Beachcomber/Seacrest/Dorcas Point water service area. Today, the Nanoose Water Service Area comprises the majority of the properties within 300 metres of the ocean on the north shore of the Nanoose Peninsula. The water source for the Nanoose Water Service Area comes from a series of groundwater wells located nearby. The water source is chlorinated and stored in three reservoirs.
