Water and Sewage Pipeline System Flaskebekk

Establishment of a water and sewage pipeline system: approx. 4,230 m of water, wastewater, and surface water pipelines on existing roads, primarily 1.7 m deep trenches with depths up to 4 m, including mass excavation. Blasting and pigging are expected due to hard rock and mountainous terrain. Controlled drilling will be used in difficult areas, especially in parts of Vardeveien and Flaskebekkveien. Installation will be carried out in shallow trenches with insulated water pipelines, surface area of the water pipeline approx. 1 m, depth to the bottom of rock trenches approx. 1.7 m. A manhole group at K20 requires multi-stage blasting to a depth of approx. 5.5 m.
