Pre-Soviet Storm Drains in Lviv
Unlike the sewer manhole covers, many of the storm drains have dates. The oldest storm drains date to 1902; there are also many from the late 1930s, especially 1939. It seems even during Austrian times the Polish name of Lviv was used, as seen in storm drain from with inscription Ed. Machan Lwow 1902.
Some of the same manufacturers made both manhole covers and storm drains, such as Ed. Machan Lwow, A. Kunz Lwow, and Słowik.
