Sewage sewers, sewage treatment plants

Sewerage

A sewer system can consist of ducts, shafts, and special constructions, e.g. rainwater drainage systems, wastewater pumping stations, pumping stations and outlets. In many conurbations, the main water collection pipelines are accessible. There are still thousands of kilometers of bricks built sewer system around the world. Modern sewerage pipes are made of concrete, steel or stoneware.

Especially the brickwork system and the concrete canals from the beginning of the concrete application are a considerable part of the concrete and need urgent repairs.

In addition to the increasingly frequent extreme rainfall which then leads to very high water velocities in the sewer systems, the permanent loads as in the above-described sewage treatment plants are the reason for a large number of damage to the sewer systems.
