Meydenbauer Bay Park Sewer Line Replacement & Phase 1 of Meydenbauer Bay Park

Project Summary

IMCO started on the Meydenbauer Bay Park Sewer Line Replacement with the City of Bellevue in December 2016. The project entails replacing a segment of the public sewer line located in Meydenbauer Bay on Lake Washington with a new 1,500 foot sewer line and associated infrastructure. A new underground pump station, associated sewer infrastructure, and removal or abandonment of the sewer line in the lake will be included in the scope of work. The wastewater from the sewer line in the lake will be directed onto the shore via a new, approximately 100-foot long sewer line segment. This segment will connect to a new underground pump station that will lift the wastewater so that it can flow, by gravity, to the Grange Pump Station. Approximately 400-feet of sewer line in the lake will be removed.

IMCO is building a sewer pump station and vault including telecommunications, power, water, HVAC and force main piping. This project includes restoration work of the developed and undeveloped Meydenbauer Beach Park and Bellevue Marina. Traffic control, dewatering, and other work will be performed to support the replacement of the sanitary sewer.

IMCO was also awarded Phase 1 of the Meydenbauer Bay Park project located at the same work site as the sewer line replacement. Major scopes of work on this project include a pedestrian pier, a beach house with restrooms, life-guard station, covered outdoor spaces, a playground, retaining walls, and other associated work. The project starts in May 2017 and will be completed within 14 months.
