Tilting weirs for excess water storage in Tilburg
Next to the Tilburg Wastewater Treatment Plant (WWTP), located on the Midden-Brabantweg, there is a large purification plant of the Dommel Water Board. This purification plant also has a water storage facility, so that there are always options for storing (excess) water in the purification process.
At this location, the national high-voltage grid operator TenneT needs space to install its new high-voltage substation.

As a result, 3 new water retention solutions are needed for the restructuring of the local area.
Mechanical engineering products for the new water storage
Commissioned by the contractor Strukton, KWT was allowed to start working on the integral design of this water storage facility in 2023 in order to develop solutions for 3 sluices.
3 Tilting weirs of 3 meters high will be used as water retention solutions, placed in concrete tubes at the aforementioned 3 sluices. The challenge here was that the design of the tube and the 3 tilting weirs needed to take place almost simultaneously. This meant weekly consultations were necessary, between the various disciplines and parties involved including KWT and its client Strukton.
Both the design of the weirs and the entire production process was coordinated with both the strict conditions of grid operator TenneT and the conditions of the end user, Waterboard the Dommel.
The functional requirements, the opening and closing times, the integration into the concrete structure and lastly the checks of the welding work (carried out using X-ray images), all together, made this project a great challenge that KWT was able to take on with confidence, largly supported by its own EN 1090 certification.
On the 7th of February, the first of these three weirs was lifted into its predetermined installation spot, along the Midden-Brabantweg and next to the sewage treatment plant in Tilburg. Thanks to the good preparation done by the contractor Strukton and the KWT Project Manager (Leon Wiltenburg), only half an hour was needed from lifting the weir, to having placed it into its place. The present installations crews then only had to spend a mere few extra hours on the final installation, which is very fast compared to conventional installation methods!
