FROM: Bob, Giberson, Public Works Director -
BY: Mike Cusick, Senior Engineer
DATE: March 15, 2013
SUBJECT: APW /APE Sewer Repair March 2013
Project No. 91340202
Emergency Resolution
ISSUE
Approve Resolution declaring an emergency which authorizes City staff to expedite repair of the
APW /APE (Andover Park W /Andover Park E) Sewer Repair March 2013 Project.
BACKGROUND
On March 11, 2013, City staff received a call from a business owner on Andover Park East reporting
sewage coming up in his parking lot. Staff discovered that the 12 -inch pipe between Andover Park
East and Andover Park West was full of sewage and not flowing. Maintenance staff then tried jetting
the sewer line, and the jet head was only able to go out about 150 feet of the 430 foot sewer line. The
sewer flow rate improved, but the jet head could go no further. When the jet head is unable to access
the pipe, it usually indicates there is a major break in the sewer pipe and has caved in.
On March 12, 2013, staff noted gravel in the downstream manhole and determined that the sewer
pipe had failed and a sink hole had formed near the railroad tracks. A temporary rental pump has
been installed to bridge the railroad tracks and the plugged sewer line.
In February 2011 this section of sewer pipe failed just east of Andover Park West resulting in a major
excavation for repair of the sewer and water lines. In 2012 the City of Tukwila received a Public Works
Trust Fund Loan for the relining of sewer pipes in this portion of the CBD for 2013. The new failure is
about 150 feet east of the failure which occurred in 2011.
ANALYSIS
Approve the Resolution which declares an emergency and authorizes Public Works to immediately
stabilize the damaged sewer system with a construction contract exempt from competitive bidding.
The scope of this sewer stabilization project is to install a rental pump with temporary piping between
the railroad ties so that train traffic is not blocked by sewer piping laying over the train tracks and then
on to a manhole near Andover Park West. This temporary system will allow the City time to hire a
consultant to design a repair project and use normal bidding procedures in hiring a contractor for the
repair. Staff will return to Committee at a later date with a Consultant Agreement for the design work.
RECOMMENDATION
The Council is being asked to approve the Resolution declaring an emergency for the APW /APE
Sewer Repair March 2013 Project and consider this item at the March 25, 2013 Committee of the
Whole meeting and subsequent April 1, 2013 Regular meeting.
