Sewers


WRE's niche expertise is in the details of wastewater infrastructure projects: how to distribute flow evenly to sedimentation basins or clarifiers; how to prevent solids from settling in the wrong places; how to get pumps to perform to capacity; how water conservation is affecting wastewater flows; how a treatment plant will perform at reduced capacity. WRE assists clients in the private and public sectors with such problems and is often called in to trouble-shoot immediate concerns. Recent project experience includes:

  • Modeling San Francisco’s combined sewer system, including development of training manuals for specialized modeling software.
  • Reassessing storage and pumping potential for a major sewer transport tunnel in San Francisco.
  • Evaluating energy use at a small wastewater treatment facility in a state prison.
