The city of Baltimore is under a Consent Decree (CD) from the Environmental Protection Agency to improve its sewer system in several areas. We performed planning, engineering, and construction services for one of the city's eight sewershed systems under the CD. Planning activities included reviewing available CCTV and manhole inspection records to determine the extent of the required work, and providing hydraulic analysis and constructability reviews of previous recommendations. The findings from these assessments and the hydraulic studies that were conducted resulted in a design memorandum that detailed the extent, methods, and limits of the rehabilitation work and hydraulic improvements.
