Bells Lane Water Quality Treatment Center

 

Bells Lane Wet Weather Treatment Facility included the design of a 160 MGD High-Rate Treatment facility. This included grit removal, chemical feed and storage, settling and disinfection, a 25-million-gallon Equalization Basin, and the renovation of the Southwest Pump Station to include two mechanically cleaned bar screens and eight 27 MGD submersible pumps. As part of the conversion, the capacity of the facility was increased. This required additional pumps, new screening facilities and significant modifications to the existing Southwest Pump Station (SWPS) facility, which included converting it to a submersible pump station. The structural scope of this project included the design of the structures listed above along with SWPS modifications, which included a new sub-grade access structure on the east side of the existing facility, a new screening building, modifications to the existing screen channels and slab openings, and significant modifications to the first and pipe gallery floors and the wet well area. All the structures in contact with combined storm and sanitary water were designed per ACI 350.  Cornerstone Engineering was the Structural Designer of Record and performed Special Inspections and Construction Administration.
