About this opportunity
The City of Marylhurst, Oregon is requesting sealed bids for sanitary sewer pump station rehabilitation under an Invitation for Bid, with bids due July 1, 2026.
The scope encompasses replacement of electrical components, mechanical piping, and submersible pumps; installation of a valve vault; and temporary sewer bypass infrastructure during wet well rehabilitation. The engineer's estimate is $410,300.00. Technical specifications, plan sheets with detailed construction drawings and equipment specifications, and a questions-and-answers addendum are posted.
Key operational constraints from the Q&A clarify site conditions: the pump station runs approximately 6 minutes per pump on average daily (12 minutes total), with documented peak run times of 77 minutes per pump during heavy rain events. The City will not permit surcharge into lateral connections on the sanitary sewer main. Temporary bypass pumping structures may be constructed during rehabilitation and removed upon completion; retention is permitted if the structure meets City design requirements for a manhole. Material substitutions or upsizing of the 2-inch valve vault drain pipe are allowed if 2-inch ductile pipe cannot be sourced. The electrical conduit schedule on sheet E4.1 contains intentional duplicate entries reflecting the original design package scope; Marylhurst Pump Station components are identified by tags beginning with "1" (G-1-0, P-1-0, P-1-1, P-1-2, etc.). Any additional structures constructed for bypass purposes are considered incidental to the temporary sewer bypass bid item.
Bidders should review all plan sheets and technical specifications carefully, as the project documents establish binding technical standards for electrical systems, mechanical piping, pump installations, and valve vault construction that govern execution and ensure compliance with industry standards and local regulatory requirements.
