Factory-Built Buildings House New Pump Station

Missouri American Water Company at their Joplin, MO, Shoal Creek Treatment facility initiated a major project to expand and upgrade facilities including replacing the existing raw water pump station with a new, larger pump station.

American Water asked Engineered Fluid Inc. (EFI) to join the project team and be responsible for the design and fabrication of a factory-built raw water pump station based on design criteria developed by American Water and the St. Louis office of Black & Veatch.

The project was a design-build, CM at Risk project headed by Reynolds Inc. of Orleans, IN.

The first phase of the expansion was to build a new raw water pump station, revamp the pre-treatment chemical feed facilities, construct a new dual 30” pipe line to the treatment plant and make extensive electrical service changes.

Because of water supply negotiations, the project had a short duration and a hard completion date. Mark Griffin, P.E., Central Region Engineering manager and Project Manager, assembled the project team under the direction of Les Archer of Reynolds. The initial pump station design criteria were given to EFI in June 2006. The required completion date was May 15, 2007. The station was delivered onto the site in February 2007, well ahead of schedule.

The Shoal Creek Raw Water Pump Station was designed as two equal halves with three vertical turbine pumps in each half. The halves were brought to the site separately and assembled together atop the basin structure. The two side-by-side modules have roof extension caps over the pump rooms with the electrical rooms at standard height.

Engineered Fluid has the ability to house larger, taller and wider equipment assemblies in its custom-built buildings. These buildings are brought to the site as individual modules and assembled to form a single, integrated equipment enclosure. Where tall equipment must be housed, add-on roof sections can be provided to raise the building height above what can be shipped as one piece.

The completed station has a total flow of 36 mgd with five pumps running at build-out. Pumps include two 5560-gpm, one 4170-gpm, and two 2780-gpm. Space is available for an additional 4170 gpm pump for future addition. The two building modules each measured 14 x 47 x 11' - 6". WW
