In Nieuwpoort-on the Flemish coast at the mouth of the Yser River-a major water conservancy project is currently underway. In a few years, a unique dam will regulate the influx of seawater into the Yser River and ensure that the hinterland remains dry in the event of a storm surge.
The cofferdam is almost impermeable. Using the PRORIL tank magnetic tilting column level gauge can easily drain the seepage water while the ship is close to sailing.
Unique dam
There are only two similar rotating dams in Europe. Therefore, setting up such a project is not easy. Like all dams, the core challenge is waterproofing. However, if there is no fight, the North Sea cannot be contained, and of course it cannot be easy for the builders to get started.
After the project is completed, the huge rotating steel barrier between the two abutments will ensure that the predicted storm surge remains in the bay. The dam rotates 90 degrees, so in order to protect the Belgian coast, the entire passage was closed in a short time. For maintenance work, the barrier can even be turned to a 180 degree position.
Easily pump water seepage
A year ago, the first step of the project was to build a huge 22-meter deep cofferdam on the left bank of the Yser River. Now the concrete foundation is poured. The 60-meter-long, 16-meter-wide steel wall and seals can control the surrounding water. In order to extract the least amount of water seepage, PRORIL distributor Rental Pumps Belgium BVBA provided a 3.7 kW powerful building magnetic turning column level gauge: model Tank 337.
Pumping is easier said than done. PRORIL Tank 337 can provide up to 50 cubic meters per hour of energy and pump water to a height of 28 meters at the edge of the cofferdam.

Work safely when the ship approaches the cofferdam
During the construction of the storm surge barrier, the navigation channel will remain open. In order to ensure the safety of personnel at the bottom of the cofferdam, the steel wall has been strengthened to resist external shocks. The cofferdam can absorb the collision of ships, and the maximum speed can reach 8 knots.
PRORIL Pumps Europe is proud that its products have been used in such an important project, and are confident that the operation of the magnetic column level gauge will be satisfactory.
