Gemaal Lely, a marvel of Dutch engineering and architectural brilliance, stands proudly just north of Medemblik in the Netherlands. This electrically powered pumping station, inaugurated in 1930, plays a crucial role in managing the water levels of the Wieringermeer polder, ensuring the land remains dry and arable. Named after Cornelis Lely, the visionary behind the Zuiderzee Works, Gemaal Lely is not just a functional structure but a testament to the ingenuity and perseverance of Dutch water management.
The story of Gemaal Lely begins with Cornelis Lely, a prominent engineer and statesman who devoted much of his career to the reclamation and management of Dutch waters. His proposals for the Zuiderzee Works, a series of ambitious land reclamation and water management projects, were instrumental in transforming the Zuiderzee into what is now the IJsselmeer. Lely's vision included the creation of several polders, including the Wieringermeer, which would require efficient water management to remain habitable and productive.
The design of Gemaal Lely was entrusted to Dirk Roosenburg, a renowned Dutch architect. Under the guidance of Samuel de Clercq, the president of the Bond van Nederlandsche Architecten, Roosenburg was tasked with creating a building that was not only functional but also aesthetically pleasing. The result is a striking structure that blends form and function, embodying the spirit of the era's architectural innovation.
The concept of reclaiming land from the Zuiderzee dates back to the 17th century, with various plans proposed over the years. However, it wasn't until the 19th century, following the successful reclamation of the Haarlemmermeer, that serious efforts were made to realize these ambitious projects. The formation of the Zuiderzeevereniging in 1886, and the subsequent studies led by engineers like J. van der Toorn and Cornelis Lely, laid the groundwork for the eventual execution of the Zuiderzee Works.
Construction of Gemaal Lely began in earnest in 1928. The Amsterdam-based contracting consortium, N.V. Aannemingsmaatschappij voorheen Hillen & Roosen and Betonbouw Trio, was awarded the contract for the substructure. The first pile was driven into the ground on April 6, 1928, and by September of that year, all 1,500 piles were in place. The construction of the superstructure followed swiftly, and by the end of 1929, the building was complete.
The pumping station is equipped with three identical pumping units, each consisting of a vertical-axis centrifugal pump directly coupled to a 3000-volt asynchronous electric motor. The pumps, supplied by the Nederlandsche Fabriek van Werktuigen en Spoorwegmateriaal (Werkspoor Amsterdam), have a normal capacity of approximately 400 cubic meters per minute. The electrical installation was carried out by Werkspoor, ensuring the station's efficiency and reliability.
On February 10, 1930, Gemaal Lely was officially put into operation, marking the beginning of its vital role in managing the water levels of the Wieringermeer polder. The station's powerful pumps work tirelessly to keep the polder dry, preventing flooding and ensuring the land remains suitable for agriculture and habitation. This feat of engineering has allowed the Wieringermeer to flourish, transforming it into a productive and vibrant region.
Gemaal Lely stands as a monument to Dutch ingenuity and the nation's ongoing battle with water. It is a testament to the vision of Cornelis Lely, the architectural prowess of Dirk Roosenburg, and the determination of countless engineers and workers who brought this project to fruition. The pumping station not only serves a practical purpose but also symbolizes the Netherlands' ability to adapt and thrive in the face of natural challenges.
For visitors to Medemblik and the surrounding region, Gemaal Lely offers a fascinating glimpse into the history and technology of Dutch water management. The building's striking design and historical significance make it a must-see attraction for anyone interested in engineering, architecture, or the history of the Netherlands. As you explore the area, take a moment to appreciate the ingenuity and dedication that went into creating this remarkable structure, which continues to play a vital role in the life of the Wieringermeer to this day.
In conclusion, Gemaal Lely is not just a pumping station; it is a symbol of Dutch resilience and innovation. Its walls echo the stories of those who envisioned and built it, and its pumps continue to protect and sustain the land it serves. A visit to Gemaal Lely is a journey through history, a celebration of human ingenuity, and a testament to the enduring spirit of the Netherlands.
