Sewerage systems form part of municipal supply and waste management infrastructure. PORR’s sewerage construction services cover the new build, renewal and rehabilitation of sewage, stormwater and combined sewer systems.

These services include the design and construction of sewerage systems, as well as the use of open-cut and trenchless construction methods. The choice of construction method is made taking into account technical, legal, hydraulic and project-specific requirements.

Depending on the project requirements, services can be provided at various stages of the project. These include design, project preparation, site management and the construction of sewerage and drainage systems.
