In connection with the establishment of a new sewage treatment plant MRIA needs to lay sewage pipelines and supply pipelines for cables to and from Tangen treatment plant.

The works include the establishment of:

— 1 Ø900 mm PE100 SDR17 emission pipeline from Tangen RA,

— 1 Ø450 mm PE100 SDR11 sewage pump pipeline to Tangen RA (from PA130),

— 1 Ø355 mm PE100 SDR11 sewage pump pipeline to Tangen RA (from Sørumsand),

— 1 Ø160 mm PE100 SDR11 supply pipeline for cables.

(NB! the estimated dimensions are given as minimum dimensions. If a larger wall thickness is chosen, the outer diameter must be increased in order to maintain the internal diameter of the pipes).
