Eastside Interceptor lining
Please note: Some of the work is taking place along railroad tracks and property. However, this is a sewer line improvement project and is not related to the rail corridor or to work planned by Sound Transit.
In early 2016, work began on sewer repairs for the Eastside Interceptor (ESI), a sewer line that carries wastewater from homes and businesses in Bellevue, Kirkland, Redmond, Issaquah, and the Sammamish Plateau to the South Treatment Plant in Renton. Work includes:
- Installing pipe lining along approximately 1,360 feet of the 72-inch diameter pipe
- Excavation at three locations to allow access to the pipeline
- Installing erosion control, supports, dewatering wells and monitoring equipment
- Restoring areas disturbed by construction
This work is part of a program to restore corroded sewer lines throughout the regional wastewater system. Pipe lining is a cost-effective way of maintaining the sewer lines. It saves on materials and energy use, when compared to installing new sewer lines.
What to expect during construction
- Traffic control: There will be signs, flaggers, and police officers present to direct construction vehicles entering and leaving the work areas
- Work hours: Hours of construction will be subject to approval by the City of Bellevue.
- Duration: Work is anticipated to be finished in five to six months.
- Work areas: There are three work areas, all along the pipeline, and generally adjacent to the railroad tracks which cross Northeast 8th Street, just east of 116th Avenue Northeast. There is one work area on the south side of 8th Street and two on the north side.
- Access to the sites will be directly from Northeast 8th Street, from private properties and from along the railroad tracks.
Wherever possible, King County will work to minimize construction impacts and keep people informed.
