As Bellevue continues to grow, Bellevue Utilities is expanding the capacity of the city's drinking water system. As part of this program, we will build a new water inlet station with underground vaults and pipes to draw water from the Seattle Public Utilities supply line in the area (Bellevue gets its water from SPU).

The site for the new inlet station is located on 136th Ave NE just north of NE 8th St. The connection to the SPU supply line (called the Tolt Eastside Supply Line or “TESSL”) will be made at the intersection of 140th Ave NE and NE 8th St. A large pipe (20-24 inches in diameter) will be installed along NE 8th St and will connect to existing pipes in the City’s water system at the intersection of NE 8th St and 126th Ave NE.

The project area includes the new water inlet station site on 136th Ave NE and transmission main pipes and connections on NE 8th St, from 126th Ave NE to 140th Ave NE. The new pipe will connect to the TESSL.

Constructing the Project

Construction is anticipated to begin in the late spring of 2020 and last for approximately one year. This schedule is subject to change once a construction contractor has been selected this spring.

What to expect during construction:

  • Noise and vibrations from construction activities. All work will be conducted within the permitted limits for noise and vibrations.
  • Trucks, excavators, and other machinery occupying work areas in the road and rights of way.
  • Traffic impacts on NE 8th St. Flaggers will direct two-way traffic around work areas and lane closures during work hours (typically 7:30 a.m.-4:00 p.m.). Traffic control measures will remain in place at all times, such as signage and steel plates, so travelers are able to move through the area safely.
  • Work at the intersection of 140th Ave NE and NE 8th St. Work in this intersection will connect the new transmission main pipe to the regional Tolt Eastside Supply Line (TESSL). It is a busy intersection so some of the work may be completed overnight from 8:30 p.m. - 4:30 a.m. One crosswalk will be closed temporarily as well for the duration of this work. This work is anticipated to last two to three weeks.
  • When construction is complete, work areas on 136th Ave NE and NE 8th St will be restored to previous existing conditions, including a new asphalt pavement overlay.
