Lake Hills sewer relining

The Lake Hills Sewer Relining Project will install pipe lining along existing concrete pipe to prevent corrosion and extend the life of the pipe another 50 years. 

Project description

As part of the Lake Hills Sewer Relining Project, King County will install pipe lining along approximately 7,200 feet of the 48-inch and 54-inch diameter concrete pipe. We will use a spiral wound technology, which allows crews to rebuild the pipe from the inside. Crews can feed the spiral wound lining in through maintenance holes, which speeds up the construction process and helps to minimize impacts to the community by repairing the pipe in its current placement.

The pipes need to be dry during lining, so we will need to reroute existing wastewater into a smaller temporary pipe. This temporary pipe would likely be routed above ground along streets, partially trenched, or be outfitted with ramps to help people and vehicles safely travel across. Construction is expected to take up to six months.

Notice 6: Construction starts on Bel-Red Road near 130th, 132nd, and 134th Avenue Northeast

King County crews have completed installing a temporary system of pipes and pumps in the east section of Bellevue’s Bel-Red neighborhood.   Crews will start construction on this section of the Lake Hills sewer pipe from September 9 continuing through October 1, 2023.

Here is what you will notice:

  • Rehabilitation of maintenance holes and pipes on Bel-Red Road and north of Bel-Red Road on 130th Avenue Northeast, 132nd Avenue Northeast, and 134th Avenue Northeast. 
  • Intersection closed at Northeast Spring Boulevard and Bel-Red Road continuing through October 1, 2023.  Access to business on Northeast Spring Boulevard up to the closed intersection with Bel-Red Road is maintained via detour from the 136th Place Northeast. Vehicles are not allowed to cross through private parking lots from Bel-red Road to access Northeast Spring Boulevard or vice versa.
  • Extension of eastbound closure of Northeast Spring Boulevard, between 130th Avenue Northeast and 136th Place Northeast. No vehicle or bicycle access on the eastbound side through October 1, 2023.
  • Intersection closed at 134th Avenue Northeast and Northeast Spring Boulevard.
  • Westbound Northeast Spring Boulevard will remain open to westbound vehicles and to pedestrians.
 


Dismount sign for cyclists on the pedestrian pathway next to 120th Avenue Northeast to safely pass through the construction detour.

What to expect:

  • Typical work hours are 7 a.m. to 7 p.m. weekdays with occasional night and weekend work.
  • There will be noise and odor from the temporary pumping system and other construction activities.
  • Sewer service will be maintained.

The interactive construction map shows active construction updates on the streets between 120th Avenue NE and NE Spring Boulevard where temporary pipes, road and sidewalk closures, equipment staging and other construction activities will occur for up to seven months.

We’ll continue to keep the community, nearby businesses, and impacted properties informed as construction progresses.

King County’s goal is to complete construction efficiently to minimize disruptions to the community. If you have questions or concerns, call our construction hotline at 425-224-2475 or email Demmelash Adera at deadera@kingcounty.gov.
