East Rocky Branch Sewer Improvements
Columbia, SC

Project consists of the replacement of the sanitary sewer piping to upsize the existing piping from Manhole SS-RB05-05541-MH to Manhole SS-RB05-14373-MH for a distance of approximately 4,700 LF with new 36” diameter gravity sewer located along Rocky Branch. Phase II includes the replacement of sanitary sewer piping from Manhole SS-RB05-14373-MH to Manhole SS-RB08-24193-MH for a distance of approximately 2,700 LF with new 42” diameter gravity sewer. The route of the new gravity sewer was very close to and sometimes the same footprint of the existing gravity sewer since the project is located in the congested area. Hussey Gay Bell’s team invested a great deal of planning/feasibility energy into the design of the new gravity system to be installed within flood prone areas and phasing and routing of bypass operations.
