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.
