Pumps
The critical role of the intake pump station, which provides the necessary mechanical lift to convey the 40 MGD influent from the Tres Rios wetlands to the elevated AWPF headworks.
Pump Alternatives
There are three primary high-volume intake configurations: Vertical Turbine, Dry Pit Centrifugal, and Submersible pumps.

Pump Scoring Criteria
Review the weighted scoring criteria used to evaluate the pump alternatives, heavily prioritizing maintenance accessibility alongside the requirement for a compact structural footprint.

Pump Station Final Design Recommendation
CJE chose the Vertical Turbine pump was ultimately selected, offering the ideal combination of a highly compact vertical footprint and ground-level motors for easymaintenance access.
