R/M, in partnership with IBC Engineering, designed an upgrade at the Influent Building at the wastewater treatment facility (WWTF). The new screen transfers captured solids from the influent flow upstream of pumping, to the finished floor level. Previously, the screenings were collected in a dumpster at the lower wet well deck level. The screenings, weighing approximately 70 pounds, were manually carried up 15 sets of stairs every day and hoisted to a refuse container at chest level.
Ruekert & Mielke, Inc. (R/M) was chosen to provide a condition assessment and long-term solution options in order to extend the life of the culverts underneath State Fair Park. The R/M team looked beyond the pipe’s internal conditions and investigated the surrounding environment to determine contributing factors to the culvert failure and future rehabilitation needs.
The major components of this upgrade included: a new clarifier with related RAS pumps, conversion of existing chlorination/dechlorination facilities to ultraviolet disinfection facilities, addition of phosphorus removal equipment, replacement of all aeration basin aerator equipment including drive units, shafts, and discs, and construction of a new headworks building, which included screening and washer/compactor equipment, grit removal, and new influent sewage pumps.
R/M provided planning, design, and construction engineering services for the aeration system upgrade. Through this project, the aeration blowers were replaced, the underground air piping was replaced with above-ground piping with continuously welded joints, and the aeration basin diffusers were replaced with a more efficient type.
