Project Description
Parsons was awarded a project with the City of Albany in November 2003 and began construction in March 2004. The project work included 25,000 lf of 26- to 42-in.-dia pipe and fitting, including butterfly valves, a US Filter-specified membrane filtration system, an intake structure, a raw water structure, a filtration building, a complete water treatment plant, and 5,000 lf of road reconstruction. Project work was divided into three schedules.
Schedule A included the construction of a raw water intake structure in the Santiam River, raw water and associated piping connecting the intake to the raw water pump station, the raw water pump station and 36-in.-dia ductile iron and 39-in. high-density polyethylene (HDPE) raw water force main, the Joint Water Treatment Plant (WTP) and Finished Water Reservoir, and the ductile iron 42-in.-dia combined finished water pipeline from the WTP up to and including the wye fitting upstream of the separate flow meter vaults for Albany Millersburg at the intersection of Berry and Century Drives. The City of Albany had furnished a membrane filtration system (manufactured by US Filter) that Parsons installed as a part of Schedule A. Also included were alternates for steel and prestressed concrete-finished water reservoir construction materials.
Schedule B included the 42-in.-dia finished water pipeline for Albany downstream wye, including the Albany flow meter vault and the downstream finished water piping.
Schedule C included the Millersburg 24-in.-dia finished water pipeline downstream of the wye, the Millersburg flow meter vault and 24-in. finished water piping to the connection point with the existing Millersburg finished water distribution system at the intersection of Berry and Century Drives, along with an I-5 undercrossing for sanitary sewer and fiber-optic conduit.
