60% Design Phase

See Engage Bainbridge site below to vote on tank graphic design (closes June 12):


The Winslow Water System serves 2,450 customers in the Winslow and Fletcher Bay areas. These areas are currently served by the two High School Reservoirs which include the 1-million-gallon Tank 1 (near the right field of the Bainbridge High School softball field) and the 1.5-million-gallon Tank 2 (behind home plate of the softball field). Tank 1 was constructed in 1973 is not up to current seismic standards and is nearing the end of its useful life. Tank 2 is not quite as old as Tank 1 but may also be seismically vulnerable and in need of upgrades, which the City is currently analyzing.

Project Description

The project consists of demolishing Tank 1 and constructing a new 2-million-gallon elevated water tank. Tank 2 will be retained and seismically upgraded (pending the analysis) but will be used only for back up and emergency use. As a result of an Alternatives Analysis, the City has selected the Tank 2 location as its preferred alternative. Both the current location of Tank 1 and the preferred location are on Bainbridge Island School District Property. The City is working with the School District to reach an agreement on the preferred location.
