The photos show a pipeline carrying cooling and additional water which is taken from the Witznitz storage near Borna and transported to the Lippendorf power plant for water treatment.

The tender documents of the project accepted both options: either pre-stressed pressure pipes made of concrete provided with interlocking connections and abutments for turns or glassfiber reinforced pipes (GRP). Due to economic reasons the decision was made in favour of GRP, i.e., glassfiber wound pipes of pressure rating PN10 with conical bonding connections by means of which abutments can be dispensed with.

Pipes in 10 m lengths, elbows, fittings and stub-ends had been prefabricated and laminated at our premises. On site the pipes and fittings were accurately installed. 6 GRP pipes in lengths of 20 m at a time were trailed with a bulldozer to the installation place and then lifted into the pipe trench by means of a crane shovel.

Short pipes which became necessary before turns or valves were manufactured according to site measuring.
