The Willowbrook water system ownership was transferred from the Willowbrook Utilities Ltd. to the RDOS on July 1, 2016. The Willowbrook water system is located within Electoral Area C between Oliver and Okanagan Falls. It provides drinking and irrigation water to approximately 80 connections. The water source, a groundwater well, pumps into the distribution system and up to a reservoir on a nearby property. The reservoir feeds the distribution system, of approximately 4.5 km of pipe, by gravity to each connection.
