Pump Station 15 CFD Models | IIHR Engineering Services

Pump Station CFD Models

Winning at Sustainability

• Sponsor: Metropolitan Sewerage District of Madison, Wisconsin

Location: 2115 Allen Blvd, Madison, WI 53705

• IIHR Involvement: Baxter & Woodman Consulting Engineers hired IIHR to create a CFD model of the existing pump station, which was being retrofitted and reconfigured to handle larger flows. The station has been set in a local green space, Marshall Park, since 1974.

Goals:

Adapt Pumping Station 15 to handle a new sewage load
Increase the sustainability of the pump long-term

Setting up for CFD Modeling

IIHR began work on the project with a trip to Madison for video of the pumps in action
Researchers analyzed the layout of the pumps
They compared the videos taken at the pumps to the CFD model back at the lab
They then preformed unsteady simulations to determine the changing flow conditions in the sump (sewage pit)

Computational Model

IIHR researchers created CFD models to determine whether or not the old sump could handle the volume of waste the new pumps would bring in
Through computational models, IIHR researchers were able to determine that Pump Station 15 would not exceed the volume of the sump and thus did not need to expand to accommodate extra sewage brought in by the new pumps
