Eastside Interceptor Section 8 rehabilitation
The Eastside Interceptor Section 8 Rehabilitation Project will repair 4,800 feet of a 90- to 96-inch wastewater tunnel in Bellevue that is nearing the end of its useful life.
Project description
The Eastside Interceptor (ESI), which consists of 14 sections, is one of the largest conveyance systems within the Wastewater Treatment Division. The ESI collects and conveys untreated wastewater from homes, businesses, and schools between Kirkland and Renton and sends it to South Treatment Plant, located in Renton, to be cleaned and released into Puget Sound.
This project will repair a 1-mile section of the ESI called Section 8 (ESI 8), starting near the intersection of Interstate-90 and Interstate-405 in Bellevue to the intersection of Coal Creek Parkway Southeast and I-405. Repairs will help the pipe last another 50 years.
