Sanitary Engineering Services, Herring Run Sewershed, Task A, E, F. Baltimore County, Maryland.

Three separate hydraulic models were developed using InfoWorks modeling software. The model was populated by importing the County’s GIS and verified with field investigations and survey data. Using the results of the I/I analysis and the calibrated hydraulic model, WR&A prepared Long Term Capacity/Peak Flow Management Reports. Using the results of the field investigations, CCTV and manhole inspection review, and the hydraulic analysis/modeling, a Sewershed Repair, Replacement and Rehabilitation (SRRR) Plan was developed to document the complete hydraulic and structural improvements necessary to prevent the occurrence of model predicted SSOs under a full range of design storm events in accordance with the County’s Consent Decree.
