New Oldenoord pumping station completed
Work on the new Oldenoord pumping station has been completed. The new pumping station was completed and taken into operation at the end of 2024, replacing the old one from 1984. The Oldenoord pumping station, located east of the village of Toornwerd on Oldenoordweg, drains the Hogepandstermaar, followed by the Startenhuistermaar. The new pumping station will improve water level control in the area.
Increase in discharge capacity
The area drained by pumping station covers 1,200 hectares. The new pump processes 125 cubic metres (125,000 litres) of water per minute, increasing the discharge capacity by 25,000 litres per minute. The water is discharged via the Hogepandstermaar into the Boterdiep. During periods of extreme rainfall, more water needs to be discharged. In dry periods, water can be pumped into the area with the new pumping station. The pumping station is operated automatically and is equipped with an automatic weed screen that stops floating material, such as plants and wood. This prevents damage to the pumping station 's screw pump.
Fish lift
A fish passage (fish lift) is part of the new pumping station. Fish are guided to a waiting room by means of an attraction current and then transported through the lock. This is important for fish migration, as it allows them to pass the pumping station unharmed.
Sustainable construction
The new Oldenoord pumping station has been constructed in a circular and sustainable manner. Both the weed scren and the steel and wooden sheet piling have been reused. It has been constructed with a modular, virtually cement-free method and is emission-free/low-CO2.
