Local 242 builds giant eggs in Washington

Members of Local 242 (Spokane, Wash.) are working with CBI Services Inc. to build two 2.8-million-gallon, egg-shaped digesters — one of the most efficient and cost-effective anaerobic systems for sludge treatment. Their shape and liquid mixing system help reduce scum, grit build-ups, and dead zones. When completed at the end of the summer, the 89-foot-wide digesters will stand 112-feet tall along the banks of the Spokane River at the Riverside Park Water Reclamation Facility.

Pictured, l. to r., are: front row, Neal Davis, John Hess, Frank Maravilla, and Justin Reardon; and back row, Jeff Weger, Jeff Voss, Dan Thiessen, Kevin Baumann, Bob Bergan, Alex Burunov, Aaron Dirks, James Dennis, and Mark Keffeler.
