Cost-efficient pump station

BELGIUM

Challenge

To provide a cost-efficient pump station fed by three independent inlets, resulting in a potential maximum inflow of 7.8 m3/s (123,000 US gpm) combined. Air entrainment into the pumps due to the three independent inlets presented challenges.

Solution
We designed a solution using four Flygt PL 7101 propeller pumps with a total capacity of 8 m3/s (127,000 US gpm). This solution is shallower than competitors’ solutions and has a lower height for lifting the water, which reduces energy consumption. The design was verified through physical hydraulic scale model tests to ensure the reliability of the solution.
