The construction of the modern Bydgoszcz water supply system began in 1897, when the construction designs were finally approved. Architectural designs of the buildings of the water supply station "Las Gdański" were made by Franz Marschal. Construction works on the SW-1 water intake were completed in 1900. At that time, the Pump Hall building on the left (facing the entrance gate) and the extension of the collecting well, and an administrative and residential building on the right were erected. The architecture of these buildings clearly shows the eclectic style, with a predominance of neo-Gothic features. The most interesting architecturally is the old pumping station, i.e. the Pump Hall, made of veneer bricks with facades, which rhythmically divide slopes, ogival blendes and windows. Additional decorative elements are openwork carved decorations placed in three triangular gables. Inside the Hall, you can admire a wooden coffered ceiling supported by a row of profiled columns with highly extended heads and stained glass windows with heron and swan motifs mounted in the eastern and western windows. The superstructure of the nearby well has also been designed in an interesting way, the attention is drawn to the lantern and decorative spire crowning it.Between the described buildings there is a new pumping station, built in 1937, which completely took over the functions of the previous pumping station. After its commissioning, the old pumping station was used until the 1990s as an iron remover hall. Today, the Pump Hall performs conference and museum functions.
