The public is invited to an upcoming open house to learn about Pierce County’s replacement of the sewer main along Brookdale Road in Parkland. The open house will be held on Thurs., June 20 from 5:30 p.m. to 7 p.m. in the Elmhurst Elementary School community room, located at 420 133rd St. E. A short presentation will be made at 6 p.m. about the project and construction schedule.

An interceptor is a sewer line that receives wastewater from multiple collector pipes and transports it to a wastewater treatment plant. The county will replace about 5,000 feet of pipe with a 72-inch diameter interceptor pipe along Brookdale Road from Golden Given Road East to A Street South. The work will begin in mid- to late-July, and is expected to last until October 2014. The existing pipes are 30-inches and 8-inches in diameter.

“The nearby interceptor pipe along 133rd Street East and Brookdale Road is nearing its capacity of 7 million gallons per day,” said Pierce County Public Works and Utilities Sewer Utility engineering supervisor Jane Vandenberg. “It’s also heavily corroded, and it’s located in an area affected by high groundwater levels. Groundwater seeps into the sewer pipe, reducing its capacity to carry wastewater. By installing a new interceptor pipe along Brookdale Road, the county will be able to increase wastewater capacity. Also, the new interceptor will be in an area less affected by high groundwater.”

About 750 feet of new 36-inch diameter pipe will be installed along A Street South to connect the Brookdale Road interceptor pipe to the existing pipe at 133rd Street East. Detour routes may be in place periodically throughout the project. There will be local access when detours are in place. The county will work with property owners to minimize impacts.
