The first phase of the Rákosvölgy main collector was built by our predecessor, Alterra Kft., and after a long period of intermission the continuation of the job we could build. The open-ditch segments are contracted to be done which will use narrow-work-pit technology, while the “pressed” sections are built using micro-tunnel technology.

- 1036 m NA1400 ROCLA and 9 m KG-PVC (average depth: 6 m)
- 1012,60 m no-dig sewer laying (AVN technology) :171 m NA1200 and 841,6 m NA 1400 ROCLA pipe jacking (average depth 8 m)
- 22 pits,
- 4 reinforced concrete constructed wetlands,
- Road reconstruction:
road: 20cm thick sandy gravel, 20 cm thick C12 concrete, 4 thick asphalt binding layers: 1584m2 and 4 thick asphalt coating layers AC11 2167 m2,
