The City of Puyallup’s Comprehensive Sewer Plan has evaluated the capacity of a 24” trunk line, which will need to be upgraded to at least a 36” diameter pipe. The first portion of the project is identified as 14A and 14B in the City’s Sewer Plan which will upsize the trunk line along 9th Ave SW between 14th St SW and 5th St SW. Project 14C identified as the trunk line north along 5th St SW between 9th Ave SW and 7th Ave SW as well as the section along 7th Ave SW between 5th St SW and S Meridian will also need upgraded. Additional modeling/ capacity analysis will be required. The total project trunk line replacement is approximately 5,655’ in length. A robust sewer bypass and traffic control plan will be required. This project will be designed altogether, however will be phased and constructed in four separate sections.
