Welcome to Cascadia Water!

Cascadia Water was formed on November 2, 2018 through the acquisition and combination of Lehman Enterprises, Inc. and Sea View Water, LLC on Whidbey Island, and is a wholly-owned subsidiary of NW Natural Water Company, LLC.  

Effective April 30, 2019, Cascadia Water closed on the acquisition of Estates Water Systems, Inc. and Monterra, Inc. on the Olympic Peninsula. Cascadia Water now serves more than 4,900 people through 1,700 connections. It will continue to operate out of Whidbey Island, and customers should not experience any disruption in service from the change in ownership.
