01What is being requested

This is a non-public tender for the construction of the new Laag-Blokland pumping station, part of the A5H Program of Waterschap Rivierenland. The project focuses on disconnecting the Graafstroom and moving excess water to the Ottolandsche Vliet, including an inlet facility for low water levels.

One part of the A5H Program is the disconnection of the Graafstroom. This sub-project consists of four interconnected measures. This tender focuses on one of these Graafstroom Measures: the to-be-constructed Laag-Blokland pumping station.   The function of the new pumping station is to pump excess water from the Laag Blokland polder and from the Graafstroom to the Ottolandsche Vliet. The new pumping station also contains an inlet facility (by-pass). In this way, during low water levels in the Laag Blokland polder, water can be let into the polder from the Ottolandsche Vliet.

06Frequently asked questions

What is the purpose of the new Laag-Blokland pumping station?
The pumping station serves to pump excess water from the Laag Blokland polder and from the Graafstroom to the Ottolandsche Vliet. Additionally, the pumping station contains an inlet facility (by-pass) to allow water from the Ottolandsche Vliet into the polder during low water levels.
Which measures are being implemented within the A5H Program?
The project includes the disconnection of the Graafstroom via four interconnected measures. An essential part is the closing of the eastern part of the Graafstroom by means of a closure device at Molenaarsgraaf/Gijbeland, which interrupts the surge and prevents water buildup.
How is water discharge regulated at different water levels?
When the closure device is open, water discharge takes place in a westerly direction via the Graafstroom and the Alblas towards Kinderdijk. At high water levels, the closure device is closed, whereby excess water from the Graafstroom and the Laag Blokland polder is pumped towards the east towards the Ottolandsche Vliet.
