Trummi (Trumm)

Drum, but not the sort you play on: one of the large drainage pipes or flues used as culverts, named in 1922 after the local kuivenduskraavi trummi (drainage ditch drum or pipe) aka truup:truubi (culvert) burying the spring called Lisaku soon (see Soone) running along the central 20% of the street. Why Trummi was chosen instead of Truubi is unclear. Once also known (dates unsure) as Brückenstraße (bridge st) or Мостовая ул. (pavement / bridge st) shedding further light: while мостовая (mostovaya) originally meant ‘street paved with round logs’, and derives from ‘bridge’, it seems to indicate the engineering consequence of covering a watercourse to make it easily passable. But see Truubi. Parent street-name of a now hydrology-themed sector.
