Pierce County will begin rehabilitating 9,600 feet of sewer pipe and about 30 manholes located along Grandview Drive West in University Place on Sept. 25.
Repairs will be made to the corroded, 30-inch diameter interceptor sewer pipe in order to increase the lifespan of the 25-year-old pipe and reduce the potential for sewer leaks.
The work will extend along Grandview Drive West from Heitman Way West to 64th Street West, and continue down 64th Street West to just west of Chambers Creek Road West. The project, managed by Public Works and Utilities, is expected to last through April 2014.
Contractors will begin by setting up traffic control and installing an above-ground bypass pipe. The bypass diverts sewage flow during the project, allowing the contractor to rehabilitate the interior of the pipe. In addition to the bypass, a new pipe liner will be installed and cured in place, which will reduce the need for large road excavations and extended road lane closures. The pipe liner protects the pipe from hydrogen sulfide corrosion.
Sections of the roadway will be periodically limited to one lane, with minimal traffic delays expected. The bike lane will be closed during the project. Some work will be conducted at night throughout the project. Noise levels will be monitored to make sure they are within allowable limits.
Electronic message boards will be used around the project site to inform travelers of any traffic-related changes. For more information about the project, visit www.piercecountywa.org/grandview.
