Standing before us is the Boezemgemaal Halfweg. It’s more than just a pumping station. It is a testament to Dutch water management and architectural ingenuity.
This municipal monument replaced the old steam pumping station in 1977. That original one dating back to 1852. Architect Dick Slebos collaborated with DHV. Together, they created a structure that is both functional and aesthetically pleasing.
The Boezemgemaal Halfweg has an interesting design. Its substructure features three flow channels. Inside these channels are screw pumps. They move excess water away. Originally, diesel engines powered these pumps. Electromotors later replaced them. The three screw pumps lift water from the Ringvaart. The water then goes from the Haarlemmermeer polder. It moves via the Zijkanaal F. Finally, it reaches the Amerikahaven and the Noordzeekanaal.
Above ground, the Boezemgemaal Halfweg has three distinct caps. Each cap covers a screw pump. Each also has its own drive and motor. These caps define the building’s unique architecture.
What is remarkable is the client’s vision. The Hoogheemraadschap prioritized both technology and design. They carefully shaped the building’s appearance. The result is a functional pumping station. It also has an architectural identity. It showcases the integration of engineering and design.
Heemschut Amsterdam recognized its value. They requested monument status in 2020 and 2021. They highlighted its modern architecture from 1966-1990. This recognition shows the municipality values post-1965 architecture. It is especially important for a utilitarian structure like this.
Future modifications are inevitable. Changes in technology and water levels are coming. The protected status ensures these changes respect the original design.
Back in 2017, Heemschut inventoried the heritage of Dutch water boards. This monument highlights this unique aspect of Dutch heritage.
The Boezemgemaal Halfweg is one of Rijnland’s four main pumping stations. It discharges water from the Rijnland polder. The location is strategic. It is at the transition from Rijnland to the Noordzeekanaal. Rijkswaterstaat manages this canal.
The pumping station is vital for water management. It removes excess water from Rijnland. It also combats salinization. The Boezemgemaal Halfweg only discharges water. Backflow preventers stop water from entering from the Noordzeekanaal.
The station acts as a barrier for migrating fish. These fish migrate upstream from brackish to fresh water. The discharge creates currents that attract these fish. A fish passage was added in 2012. It assists eels and sticklebacks.
Dick Slebos designed the Boezemgemaal Halfweg. It has a perfect blend of technology and architecture. This is evident in its colors and materials. It is a functional structure that enhances the landscape. The location is striking. It is in a landscape of pastures and waterways. The Wethouder van Essenweg runs over the pumping station. This adds to its urban value. The three caps are visible from afar.
The building’s design includes various features. These are smooth concrete surfaces. Also, textured concrete and B2 blocks. Metal parts provide contrast. Doors are green. Moving parts like the crane are red.
The complex includes other structures. There are two octagonal volumes. They contain a boiler room, staff rooms and a meeting room. The upper floor is glass-enclosed. This offers panoramic views. Two former residences and storage areas are also part of the design.
From the road or water, the three caps stand out. Concrete is used extensively. This creates a cohesive appearance. The Boezemgemaal Halfweg is a testament to collaboration. The client chose an architect. The architect and engineers worked together. The result is a functional and recognizable structure. It embodies Dutch water management. It also shows architectural innovation. The Boezemgemaal Halfweg gained municipal monument status in 2021.
