Sewerage systems: Design and supervision 

COWI designs sewerage systems of all dimensions and types. We offer creative services tailored to the needs of our clients and to local conditions. Our services involve not only pipe systems but also all other sewerage system components.
Sewerage systems are an important part of the infrastructure in any society, especially in modern urban settlements. Wastewater from buildings and industries must be transported safely and hygienically to a wastewater treatment plant without nuisance in the form of odour, flooding or damage to the environment. Solutions must be profitable and easy to operate.

All types of components for sewerage systems

COWI has in-depth experience of many kinds of sewerage facilities:

  • Pipe systems
  • Sewer appurtenances
  • Retention basins
  • Pumping stations
  • Sea outfalls
  • Drainage and dewatering
  • Flushing systems for sewer cleaning, fine screens and flow regulators

Means of collaboration

Often, the traditional means of collaboration with the consultant that is designing and tendering general and individual trade contracts is the most efficient solution. On other projects partnering is to be preferred. COWI has participated in a number of sewerage projects where partnering between client, contractor and consultant has been the means of collaboration. Partnering allows for a close dialogue and optimum use of the ideas and know-how of all parties involved.
