Initial I/I reduction projects

Location of initial I/I reduction project

In accordance with the adopted Regional I/I Control Program, in 2011 King County began construction of an I/I reduction project in the Skyway Water and Sewer District service area (unincorporated King County). I/I projects were also planned in Bellevue and Issaquah; however, in 2010 King County budget limitations led to a decision not to implement these projects.

While some of the sewer rehabilitation work has focused on the public portions of the sewer system (sewer mains and manholes), much of the rehabilitation on private side sewers with the cooperation of property owners has occurred. King County and Skyway Water and Sewer District are working with the affected communities during the implementation of the project.

The results of this initial project will be used to develop recommendations to the King County Council regarding long-term I/I reduction and control, including applicable changes to policy or code
