Sunnyside Wastewater Treatment Project

Client: Lake Stevens Sewer District
Location: Lake Stevens, WA
Notice to Proceed: January 2009
Completion Date: June 2012
Original Contract Amount: $88 million

Work is progressing on the 14-acre site for the Lake Stevens Sewer District. The project in Lake Stevens, WA, will run through 2011. It includes the wastewater intake, an aeration system and an ultraviolet disinfection.

Balfour Beatty Infrastructure will also construct a generator building, an administration building, a shop, earthworks and a stormwater detention pond. The engineering firm Gray & Osborne is the designer of the plant, which is designed to handle 5 million gallons per day. The Sunnyside plant will replace the Ebey Slough plant, which has lower capacity and is less environmentally sound.

The project, which began in September 2008, includes installation of a lift station and sewer pipeline just north of the plant. Workers will place an effluent pipeline into a trench in the existing slough.
