St. Emanuel Pump Station Hydraulic Modeling Study
As part of the North Houston Highway Improvement Project (NHHIP), TXDOT required a stormwater pump station capable of managing 100-year, 24-hour design inflows from two directions. The St. Emanuel Pump Station’s dual-inlet configuration and high capacity—over 100,000 GPM—posed significant hydraulic challenges, particularly in meeting ANSI/HI 9.8-2018 standards. Risks included air-entraining vortices, excessive swirl, and pre-rotation near pump intakes, all of which could compromise pump performance and longevity. Verdantas Flow Labs conducted a detailed physical hydraulic model study at a 1:5.3 geometric scale, supported by complementary CFD simulations.
