Pumping station C. Mantel is a new pumping station at the ‘Markermeer’ side of the working area of the water authority and ensures a stable water level in the largest part of the province North Holland. In order to allow a more rapid drainage of rainwater, Pentair Fairbanks Nijhuis supplied four fish-friendly pumps. In terms of capacity and size they are the largest fish-friendly pumps we have produced so far.
Remarkable is that, the pumps are interchangeable. In addition, one of the pumps is reversible, so it can also be used in dry periods, in order to pump water back to the polder. We also used a new anti-fouling coating for these pumps. This coating has a very hard top which makes it almost impossible for cockles to attach to the pump. This has a favorable influence on the performance and service life of the pumps.
