Relief of a sewer system
The Landsberger Straße sewer network renovation, 2nd construction phase, is intended to relieve the existing sewer system in the Pasing and Laim area, which dates back to the middle of the 20th century.
In order to drain the large quantities of wastewater in the west/south-west of Munich, a new sewer is planned in Landsberger Straße, which, once completed, will connect to the DN 3000 sewer already constructed at the Laimer roundabout and drain the combined wastewater via the Hirschgarten rainwater retention basin. The 2.2 kilometre long tunnelling section starts at the roundabout in Laim and ends at "Am Knie" in Pasing. Wayss & Freytag Ingenieurbau's tunnelling division is constructing the sewer on behalf of Munich's municipal drainage system.
