"Dętka", Museum of Sewer

"Dętka" is an original drainage canal in the form of an ellipsis. It’s a 142-meter brick tunnel created in 1926 as one of the first sections of the city drainage system. Designed by the creator of Lodz and Warsaw waterworks, William Lindley, and built under the supervision of the constructor of the Lodz system, Stefan Skrzywan, up to the 1970’s it functioned as a tank for rainwater collected for flushing street collectors from the Liberty Square in four directions of the world. Since the square is the highest point in the vicinity, the water flowing down by force of gravitation effortlessly flushed mud. The canal stopped functioning in the 1970’s, when the Waterworks and Sewage System Company began cleaning through other methods. Currently, it is a tourist attraction. “Dętka” is properly ventilated and dimly lit so as to preserve the atmosphere of the place.


ATTENTION: The museum is closed due to safety reasons until further notice.
