Wastewater Treatment Workgroup

Scope and Purpose

Originally created in 1995, the group now serves to provide a formal means of interaction & communication amongst and between Federal agencies, state agencies/jurisdictions, & wastewater treatment plants. Functions include:

  • Provide a forum for the discussion and exchange of information between the Bay Partners, stakeholders, and the CBP concerning: nutrient loading estimates and nutrient removal technologies, along with the associated implementation costs.
  • Provide the technical leadership and provide input concerning point source issues for the Tributary Strategy Revision Process.
  • Track annual nutrient reduction progress and coordinate the information to the NSC’s Tributary Strategy Workgroup for inclusion in their annual Tributary Strategy Statement of Progress.
  • Provide data and support for the Modeling Subcommittee activities.

    This project page is the repository for Wastewater Treatment Workgroup resources relating to the Phase 6 model, its documentation, as well as files and links to Tableau pages. Please email Michelle Williams (williams.michelle@epa.gov) with any wastewater-related questions. For modeling questions, please email Kyle Hinson (khinson@chesapeakebay.net).

    Documentation

    All documentation files will be uploaded to this FTP site to assist in partnership review of Phase 6: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Documentation/

    Calibration

    A summary PDF of calibration results has been generated and is available for download (large file): ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/Calibration_Figures/00_Calibration_Figures_All_Phase6Draft.pdf

    Other detailed calibration results for each calibrated parameter and river segment can be found in a separate FTP folder: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/Calibration_Figures/

    Further detailed calibrated output for the watesrhed can be found in csv files located at this FTP site: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/Summary_Loads/

    Further comparisons between the Watershed Model and WRTDS can be found at he non-tidal indicator page: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/WRTDS_Comparison/
