From left, Dale Arnold and Lars Hendron, of the city of Spokane, and Hollis Barnett and Tim Welsh, of Garco Construction, take a tour Tuesday atop the new digester at the wastewater treatment plant on Aubrey L. White Parkway.

Officials say the egg shape of the new digesters is safer, allowing for better mixing, less maintenance and lower energy use.
