The WET Science Center is a fun, hands-on place to learn all about water – one of our most precious resources. Exhibits and games for all ages focus on water conservation, wastewater treatment, reclaimed water use, clean water careers, and protecting Puget Sound. The science center is owned and operated by the LOTT Clean Water Alliance, a nonprofit corporation providing wastewater management services for the urban areas of Lacey, Olympia, and Tumwater.
