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.

Starting as early as Monday, January 5, 2026, the Cross Kirkland Corridor (CKC) trail between Northeast 52 Street and 108 Avenue Northeast will be closed to the public.

King County Wastewater Treatment Division anticipates that construction will last through February 2026. We will provide advance notice of construction activities and future trail openings through web bulletins, emails, and text messages for project subscribers.

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.
