The Civil Structures Group provides analysis and designs for heavy civil structures including tunnels, roads, bridges, canal appurtenant structures, and in-river structures. The group also provides team leaders for final design projects, appraisal studies, and feasibility design studies. Engineers specialize in structural and hydraulic designs for:

  • Roads and bridges
  • Canal headworks, check structures, and gated waste ways
  • Pressure, free flow, and access tunnels
  • Underground chambers and shafts
  • Reinforced or prestressed concrete storage, surge, or regulating tanks
  • Diversion structures, fish screens, fish ladders, fish barriers, and reservoir and other structures

Water Treatment (8190)

Group Manager:  Michael (Mike) Kramer (mkramer@usbr.gov; 303-445-2946)

The Water Treatment Group provides engineering and research services for the treatment of contaminated water supplies, wastewater, hazardous and industrial waste streams, and agricultural drainage. The group combines the multidiscipline expertise of chemical, environmental, and mechanical engineers to develop comprehensive water treatment solutions. Specific capabilities include:

services and equipment

  • Development of treatment goals and process options based on water quality, regulations, applicable technologies, environmental impacts, costs, and client preferences
  • All phases of planning and design from preliminary studies to preparation of specifications and drawings for design-build and construction contracts
  • Laboratory bench and field pilot testing of treatment equipment including development of test plans, equipment assembly, data collection, sampling, and analysis
  • Evaluation of regulatory and permitting requirements for treatment systems
  • Troubleshooting and retrofitting of existing treatment systems
