01What is being requested

Renovation of 4 bellows sluices near the Haarlemmermeerpolder, consisting of the replacement of mechanical, electrical, and process automation installations, the renewal of rubber fabric, and the excavation, conservation, or new construction of bottom box structures.

Hoogheemraadschap van Rijnland manages four Bellows Sluices. These were built in the 1960s to allow for the compartmentation of water in the Ringvaart of the Haarlemmermeer in the event of a dike breach. Sinc some time, the Bellows Sluices have not been fully functional. Rijnland has therefore decided to renovate the four Bellows Sluices.
