General Construction Work For Pipelines – Connection Wv Fr West To Geothermal Energy Wv Tel-Aviv-Yafo. The District Heating Pipeline Along Tel-Aviv-Yafo-Allee Is Crucial For Connecting The Freiburg West Heating Network To The Future Geothermal Heat Supply. In This Construction Phase, The Existing District Heating Pipeline From The Intersection Of Tel-Aviv-Yafo-Allee / Adelheit-Steinmann-Straße Will Be Continued.
