Halifax pumping station (Canada)

Improvement of a water pumping station

Client: Degrémont SA - Scale: 1:10

Context and aims of the physical scale model

The Halifax raw water pumping station was experiencing vortex problems on the pump suction side. The aim of this scale model study was to recommend a reliable technical solution for preventing the development of these vortices.

Description of the physical scale model

Once the model had been adjusted, based on the existing configuration, a series of improvement tests were performed:

  • Improvement of flow conditions in the chamber and in the vicinity of the pumps;
  • Elimination of vortex problems by proposing some simple anti-vortex systems, some simple geometric changes to the pumping chamber, etc.

The measuring device were :

  • a graduated scale and some level gauges

  • an electromagnetic flow meter
