Eastside Interceptor Section 14 joint rehabilitation
Repairs are underway to a sewer pipe that runs along the Cross Kirkland Corridor (CKC) Trail north of 108th Avenue NE.
Eastside Interceptor Section 14 (ESI 14) sewer pipe is a 7-foot diameter pipe, which carries 10 million gallons of wastewater a day on average during dry weather. In late July 2025, King County and City of Kirkland crews detected a leak from the County’s ESI 14 sewer pipe that was entering Kirkland’s piped stream. King County coordinated with Public Health – Seattle & King County, and no public health risk was identified.
In September 2025, King County Department of Natural Resources and Parks issued a Declaration of Urgency to expedite the repair efforts. The City of Kirkland also issued a Proclamation of Emergency to aid in repairs.
Project update
Wastewater to be diverted to temporary above-ground pipe in Kirkland
January 13, 2026
Construction to repair a leaking sewer pipe continues along the Cross Kirkland Corridor (CKC) Trail. As early as Tuesday, January 20, wastewater flows in the Eastside Interceptor (ESI) 14 sewer pipe will be diverted to a temporary above-ground pipe.
Last fall, crews installed a 3,000-foot temporary 18-inch pipe along the trail. Sewage from this section of the pipe will be pumped into this temporary pipe so crews can safely fix the pipe while it is empty.
Generators and pumps will push flows to the temporary pipe. An additional generator and pump will also be running to keep the dig site dry. The temporary system will maintain sewer service to your home. Once the pipe is fixed, flows will be returned to the ESI 14 pipe. Crews will also remove the temporary pipe and restore the trail. Construction is anticipated to last through February 2026. View construction notification for more information.

Project background
The Eastside Interceptor (ESI), which consists of 14 pipe sections, is a large and critical component of King County’s wastewater conveyance system. The ESI collects and carries untreated wastewater from homes and businesses in Kirkland and sends it to South Treatment Plant in Renton, where it is cleaned and disinfected before the water is released into Puget Sound.
