Germany – Underground work other than tunnels, shafts and subways – Wasserwerk Kleinensee Nord Leitungsbau

The Stadtwerke Lübeck Energie GmbH plans the construction of a new groundwater intake north of the Kleinensee waterworks with five wells and its connection to the waterworks. The laying of the raw water pipe between the wells and the plant, along with accompanying empty conduits for power supply and fibre optic connection of the wells, will be tendered. A total of approximately 5.5 km of PEHD raw water pipe in various nominal widths up to DN 500 is planned. Of this, 2.8 km will be laid in open construction across agricultural land, 0.9 km in open construction in the middle of a road, and 1.8 km will be laid using the HDD method. Eight HDD boreholes are planned under hedgerows and roads, as well as two approximately 500m long double boreholes. The new pipeline will be connected in the pipe cellar of the waterworks. Permit reservation: The procedure is subject exclusively to the complete and legally binding grant of all necessary permits. Until these permits are available, there is no entitlement to the performance or remuneration of the tendered service.
