King County to replace Lincoln Park sewer line

King County will start this weekend on a four-month construction project to replace more than a mile of sewer line that runs through West Seattle's Lincoln Park. The 50-year-old line was damaged after heavy rains and high flows on Jan. 17 and Feb. 6, causing sewage leaks in Lincoln Park (links).

The county decided to replace the line after Wastewater Treatment Division inspectors discovered extensive wear and corrosion throughout much of the pipe, which pushes wastewater from the Barton Street Pump Station north of the Fauntleroy ferry dock through a 6,250-foot pipeline to the county's Murray Avenue Pump Station at Lowman Beach Park.

To keep the system operating normally during construction, crews installed a temporary 6,000-foot-long, 18-inch-diameter surface pipeline along the beach to carry wastewater from an interim pumping facility at Barton to a manhole south of Lowman Park where it will be discharged back into the system and go to the West Point Treatment Plant in Seattle.

When the temporary pipe and pumping station begin operating this weekend, the county will no longer need to bypass the damaged line using trucks to haul wastewater from Barton to the Alki Treatment Plant. The temporary pipe will also enable the county to stop bypassing about a million gallons of wastewater a day to an outfall in Puget Sound, which will protect water quality.

Contractors will begin permanent repairs next week, installing a new, 24-inch plastic pipe inside the existing line, which will take about a month. Lining the old pipe is more efficient and cost-effective because the old pipe will not need to be dug out and removed.

When the pipe lining work is finished, the system will once again begin normal operations and the temporary equipment will be removed.

But because the new pipe lining will restrict capacity, King County will need to spend three additional months installing a second 24-inch pipe that will run parallel to the newly repaired line. Two pipes will add enough capacity to increase system reliability.

Contractors will begin trenching along the beach in March, starting from the south end of Lincoln Park heading north.

King County and Seattle Parks Department are coordinating to get the work finished as quickly as possible. During construction of the pipeline trench, the beach will be closed to protect public safety. The rest of the park will remain open, and people will still be able to rent facilities.


The county will also be holding meetings with neighborhood groups and the public to answer questions and address concerns.

King County's Wastewater Treatment Division protects public health and water quality by serving 17 cities, 17 local sewer utilities and more than 1.4 million residents in King, Snohomish and Pierce counties. Formerly called Metro, the regional clean-water agency now operated by King County has been preventing water pollution for more than 40 years.

King County repairing leaky sewer line in Lincoln Park

A King County contractor is repairing a 30-inch sewer line in Lincoln Park after wastewater workers discovered a sewage leak Tuesday near a sinkhole that developed late last week during heavy rains. One of several storm sewers crosses the sewer line near the sinkhole.

To stop the leak in the park and enable sewer repairs, King County's Wastewater Treatment Division began an emergency bypass at its nearby Barton Street Pump Station on the north side of the Fauntleroy ferry dock. The bypass will protect public health and prevent personal injury and severe property damage. King County is temporarily discharging a mixture of stormwater and diluted sewage through an outfall 620 feet offshore.

King County discovered the leak early Tuesday afternoon. King County posted the beach as closed, took water samples, and told health and regulatory agencies about the leak.

Normally, the Barton pump station pushes wastewater from the Fauntleroy area through a 6,250-foot pipeline to the county's Murray Avenue Pump Station at Lowman Beach Park.

During major storms, the Barton station works as an outfall for excess rain combined with diluted wastewater. Flows normally go to King County's West Point Treatment Plant, which treats up to 440 million gallons of wastewater a day during storms. King County and the City of Seattle are carrying out a multimillion-dollar program to prevent most combined sewer overflows.

King County's Wastewater Treatment Division protects public health and water quality by serving 17 cities, 17 local sewer utilities and more than 1.4 million residents in King, Snohomish and Pierce counties. Formerly called Metro, the regional clean-water agency now operated by King County has been preventing water pollution for more than 40 years.

In 2000, the Morgan Community Association received CRF funds to install a traffic calming project at 40th Ave SW and Fauntleroy Way SW. The project was installed in 2004. Along with a new concrete sidewalk and barrier extension on the east side of Fauntleroy, an overgrown, weed infested triangle on the west side was regraded and planted with trees and a new low maintenance grass called Ecoturf.

While the Parks Department agreed to provide once a year mowing, the expected effort needed to trim back the Ecoturf, within 2 years aggressive weeds overwhelmed the Ecoturf and the triangle quickly turned back into a weed infested planting, although with nice trees.

This year, nearby neighbors decided to deal with “Weed Island” just as aggressively as the plant invaders and have formed several work parties to provide mowing services to keep the weeds in check. Along with the tidy trimmed look has come the return of wildlife; several pink flamingos have been spotted nesting in the pine trees, and a Halloween decorating party may bring back bats.

Thanks go to Paul Sureddin who help coordinate the taming of Weed Island, along with neighbors Dave and Linda Gould, Shawn and Susan Terjeson, Kevin and Jaye Bywater, Mona Beery, Janine Rees, Gene Brake, Greg Stripes and others.

City Repair Seattle is a non-profit organization that has a goal of improving communities through public participation and creating gathering places, public art and identity in local neighborhoods. City Repair is offering a public workshop on "Place Making" on January 21, 2006. Please see the Seattle PI news article on City Repair (Link below).

MOCA is hoping to use City Repair as part of the public planning process for developing a public plaza in Morgan Junction in 2006. The Seattle Parks Department is funding the construction of this plaza through the Pro Parks levy. The plaza was recommended in the Morgan Junction Neighborhood Plan.

If you would like to attend the workshop, you must first register. Please call Cynthia Shick at (206) 322-6295.
