EWVA Schleppe site Klagenfurt am Woerthersee, renewal by construction of a new supply pipeline including connection to the existing network

01

The works concern the renewal of a drinking water supply pipeline at the Schleppe site in Klagenfurt am Woerthersee. Starting from the pump station at node 1, the existing main supply pipeline (AZ DN150, built 1964) is replaced by a new PE100-RC DN/OD180 PN16 pipeline up to existing valve shaft no. 1 at parcel no. 164/1, cadastral community 72196 Waltendorf, where age-related pipe damage has occurred. The Falkensteinerbach stream is crossed by underboring about 1.5 m below the stream bed over roughly 4 m. An overflow and drain line (about 3.50 m PE100-RC DN/OD110 PN16) with automatic valves is installed after the UV system, discharging untreated well water via a precast concrete soakaway shaft DN1000 with a 2.0 x 2.0 x 0.5 m infiltration body. An existing PE 1 inch supply line serving three properties on Trettnigstrasse is reconnected with about 2.0 m PE80 DN/OD32 PN10 pipe, and a DN800 shaft with a 400 kN locking cover is built in the green area.
