The project included the construction of trunk sewer D (the Tkalcovská Structure) at the length of 1234 m, the trunk sewer in Táborská Street at the length of 1060 m, the sewer in Merhautova Street at the length of 570 m, construction of K18 Zelený vrch collector at the length of 642 m and separation sewage collection network in the City District of Brno – Líšeň.
The sections of the sewers range from DN 2,312 mm to DN 800 mm, the diameter of the collector is 14 m2.
The shield driven technologies, conventional excavation or open cut in combination with pneumatic formwork were applied in the construction of sewers. In the course of the construction, the adjacent structures were also constructionally secured and the old part of the sewage collection network was removed. Service connectors to houses and house inlets were gradually connected to the existing operational sewer. Road surfacing work was subsequently carried out, including tram line reconstruction and the renovation of pavements.
