Polyhedral composite pipes and sections can use for reconstruction:
- urban networks of domestic and storm sewage
- municipal networks of underground rivers and streams
- city drainage water intake and drainage systems
- sewage networks of large enterprises
- water pipelines of nuclear, thermal and hydroelectric power stations
- culverts of railways and highway
Polyhedral composite pipes can use for the construction of new modern underground reservoirs, conduits, tunnels, wells, tanks, etc.
Networks of underground sewerage in cities are very long, about 10% of them are a large-diameter collector.
The length of the sewage networks of large cities:
- Moscow: household sewerage more than 8760 km.
- St. Petersburg: household sewerage about 8800 km, tunnel manifolds – 270 km.
- Novosibirsk: household sewerage 1150 km, tunnel sewers – 100 km.
- Kiev: domestic sewerage more than 3000 km.
- Kharkov: household sewerage 1660 km., tunnel collectors – 56 km.
- Lviv: household sewerage is 765 km.
- Odessa: household sewerage about 680 km.
- London: only the Bazalgette system consists of 1,100 miles of street sewage and 82 miles of main sewerage networks. Built-in 1855.
- Berlin: a combined sewage system with a total length of 1,900 km built-in 1873. The Berlin sewage drains have a distance of 9,600 km.
- Prague: the length of the sewerage system was more than 4,500 km.
- Paris: In 1805, the construction of 182 new miles of sewerage, today Sewerage extends for 1,300 miles.
- Vienna: the length of about 2500 km. Construction started in 1837.
- Krakow: sewerage system approx. 1858 km.
- In Brussels, there are about 1500 kilometres of sewer networks, which now require serious attention.
- Hamburg: is about 5,800 kilometres. Construction started in 1842.
- Frankfurt-on-Main: an extensive public sewage network with a length of about 1600 km.
