  • Pumping stations
  • Waste water treatment plants
Efficient drainage systems are crucial for a road to survive its entire service life. CeS.TRA has gained international experience in planning, design and supervision of road surface drainage infrastructure. We work closely with traffic and road designers, early within the project to achieve the optimum highway layout and drainage strategy.

What we do:

  • Hydraulic and hydrological considerations in highway planning and design
  • Evaluation of highway effects on surface water environment
  • Hydraulic analysis for the location and design of bridges
  • Design of culverts
  • Hydraulic analysis and design of open channels
  • Hydraulic analysis and simulation modelling of highway storm drainage systems
  • Design of storm water flow attenuation measures
  • Discharge license applications
CeS.TRA has proven experience in implementation of successful river management projects. Our objective is to provide innovative and cost-effective advice and guidance, whether it is for strategic planning or detailed design.

What we do:

  • Catchment hydrology
  • Hydraulic assessment of networks and receiving waters
  • Flood hazard modelling and mapping
  • River stability assessment
  • Prediction of erosion and sediment transport
  • Optimization of the location of structures in rivers
  • Design of bank protection and river training works
  • Design of flood protection embankments
  • Design of sediment traps
  • Consultation and negotiation with statutory authorities
CeS.TRA provides collaborative multi-disciplinary team to develop projects, from concept initiation to detail design of the rehabilitation works on disposal sites and abandoned dump sites. We evaluate environmental risks and compile an overview of the necessary remedial measures and associated costs.

What we do:

  • Site identification and evaluation
  • Environmental due diligence
  • Waste management
  • Environmental impact assessment
  • Landfill design
  • Assessment and restoration of closed landfills
  • Landfill closure and aftercare programs (landscaping, re-cultivation)
CeS.TRA has led the Environmental Impact Assessment (EIA) of massive projects in recent years, where the EIA forms the framework within which environmental risk assessments are performed. We are familiar with working to all current EIA related methodologies and delivery of multi-disciplinary EIA, from the scoping stage, through to representation at public inquiry where required.)
CeS.TRA has the experience and expertise necessary to undertake assessments of railway noise or road traffic noise, in order to develop proper mitigation measures, and in support of planning applications for residential developments. We rely on state-of-the-art modeling software (CadnaA) for production of noise contours defined by current and future noise sources.

What we do:

  • Noise mapping
  • Evaluation and design of noise mitigation actions
  • Evaluation of environmental noise exposure
