Wastewater pipeline, pump station project to begin

by Andrew Walgamott

   King County will soon begin construction of a $45 million pump station and pipeline project that will divert wastewater in the Woodinville-area from a sewage line expected to reach capacity next year. The project may also lead to development of four acres of ballfields for Bothell-area residents when construction wraps up.

   Construction of the 36 million gallon per day capacity North Creek Pumping Station in the Quadrant Business Park of Bothell and installation of twin 30-inch pipelines is expected to take more than two years, according to Dave Dittmar, King County Department of Natural Resource project manager. The pipelines will stretch for 4.5 miles and take wastewater collected at North Creek to the York Pumping Station on N.E. 124th Street east of Totem Lake. The pipeline will be tunneled under State Routes 202 and 522 and will follow the Burlington Northern-Santa Fe right-of-way from approximately Little Bear Creek to N.E. 145th Street.

   By following the railroad right-of-way, traffic and local businesses won't be disrupted, and buried utilities along major streets won't have to replaced, according to Dittmar.
   From N.E. 145th Street, the pipeline will cross the J.B. Sod Farm to the York station where it will be piped to the Renton treatment facility. When the project is finished in approximately 28 months, ballfields may be built on portions of the five acre North Creek pump station site, according to Dittmar. He said King County and Bothell are working on an agreement to allow four acres to be developed for athletic facilities.

   Also in the works at North Creek is an underground storage facility to hold wastewater overflows. Dittmar cautioned that the tank won't be built for 20 years. Woodinville, Bothell and south Snohomish County are currently served by the Lake Line Interceptor that carries area wastewater to the Westpoint Sewage Treatment Facility in Seattle.
   The interceptor, which skirts Lake Washington, will reach full capacity in 1998 due to growth in the area. Last winter, the pipeline overflowed into Lake Washington once. Development of the new pipeline should prevent future overflows, according to Dittmar.
