Keystone Projects
Manchester Seawater Replacement- Port Orchard, WA
National Oceanic & Atmospheric Administration (NOAA)- Design-Bid-Build
Engineer: Iron Horse
The project included the construction of a new seawater distribution system to support ongoing research at the Manchester Fisheries Research Station. Prospect installed over 6,000 feet of underground HDPE piping ranging from 3" to 24" throughout the Research Station while maintaining continuous facility operations. Prospect also constructed a new filtering facility, head tank, and multiple distribution manifolds. Work also included the treatment and disposal of PFAS / PCB contaminated soil and groundwater as well as construction of a building pad using Drilled Displacement Rigid Inclusion ground improvement methods.
Soos Creek Fish Hatchery- Auburn, WA
Washington State Department of Fish & Wildlife- Design-Bid-Build
Engineer: KPFF
Originally constructed in 1901, the existing Soos Creek Fish Hatchery was one of the first built in Washington State. In an effort to replace failing aspects of the existing hatchery, and to upgrade the hatchery to assist the Washington Department of Fish and Wildlife meet new production goals, the Soos Creek Fish Hatchery Project has been undertaken. The project includes the construction of a new comprehensive fish hatchery on the opposite side of the creek from the existing hatchery. Components of the new hatchery include New Obermeyer weir, juvenile bypass, fish ladder, intake structure with mechanical building, 5 adult tanks, 18 raceway tanks, drain box, heavy settling structure, pollution abatement structure, distribution box, round RFP Ponds, hatchery building, fine settling structure, new bridge, office building, and associated site piping and heavy civil work. The project requires that in water work be completed in two in-water fish windows. After completion and commissioning of the new hatchery, the existing hatchery was demolished and the site restored to a wetland.
Crow Pump Diversion Reconstruction- Ronan, MT
Confederated Salish & Kootenai Tribes – Design-Bid-Build
Engineer: DOWL
The project involves a stream diversion of the crow creek and demolition and replacement of the existing pump house and dam structure with a new fish ladder, sluice walls, wet well and pump building along with the 4 new 16" vertical turbine pumps and an Ice/Frazil system for the intake screens. The project also includes the installation of ~2600 LF of 24" Fused HDPE pipe and ~3700 LF of new 48" Fused HDPE transmission line
Jocko Area Canal Conversion Project - Phase 1 And 2- Ronan, Mt
Confederated Salish & Kootenai Tribes – Design-Bid-Build
Engineer: Morrison-Maierle, Inc.
The project generally consists of, but is not necessarily limited to, the following major items: Conversion of an existing irrigation canal system to a piped system including: 1) Two new intake structures on an existing K canal, 2) Sensors, actuators, and associated electrical components to allow for local control, and eventually remote SCADA operations, at the intake structures, 3) Approximately 34,000 LF of HDPE pipe ranging in size from 2-inch to 48-inch with most pipe provided by the owner, 4) Isolation valves consisting of gate valves and butterfly valves, 5) Pressure reducing valve stations for managing pressure in mainlines and smaller pressure reducing valves at select on-farm deliveries, 6) Air valves consisting of air release valves and combination air release/air-vacuum valves, 7) Individual on-farm delivery assemblies consisting of isolation valves, air valves, flow meter, and ductile iron pipe, 8) Erosion control, 9) Road repair and surface restoration, 10) Valve and meter vaults, and 11) Drainage structures consisting of concrete dry wells and stilling basins. Owner provided items are extensive and includes most pipe and appurtenances.
Owl Creek Irrigation District Water Delivery & Efficiency Project – Hot Springs County- WY
Owl Creek Irrigation District- Design Bid Build
Engineer: Western Heritage Consulting & Engineering
Work included construction of irrigation district infrastructure including new pump station construction. New pump station construction included a new 1,400 sf pre-engineered steel building with 7.5 ton overhead bridge crane and all new pumping equipment, electrical service and coordination with Rocky Mountain Power, and up to 1,050’ discharge pipeline and discharge structure renovation. The new pump station was built adjacent to the existing pump station, work required foundation excavation of 20 feet of material and dewatering while maintaining canal flows to the adjacent lift station in order to facilitate the structural concrete construction for the new station. Pump installation include two 500 HP vertical turbine pumps capable of 22.8 CFS and two 250 HP vertical turbine pumps capable of 23.4 CFS. Pumps required the installation of new mechanical piping and valves. In addition to the new pumps PCI installed a traveling water screen to screen debris from the canal before entering the pump station. PCI also removed and replaced approximately 1,050 LF of 36-inch discharge pipe, with roughly 450 LF of the being on slopes at or exceeding 50%.
PCI performed the work within extremely close proximity to existing overhead high voltage transmission mains and while maintaining irrigation flows to the existing pumping plant.
